Great Dane excavating co.

[Cooper]

After reading all the other threads and enjoying the builds and work I decided to join in. I'm Cooper, actually my name is R.W. . Cooper was one of my Great Danes , hence the excavating company name and logo. I am on my first year in the rc construction toys but hooked!! I'll post pics, builds and just some general thoughts involving the equipment.

So some company info, I'm in central pa. Every job is too big. The customer is not always right. If you don't like the work we can work for as long as you like (it's your dime). Our hours are from sometime in the morning till whenever we get tired of working. We are open seven days a week but will be closed when you need something. Disagreements will be handled by receiving complementary sand and boxing gloves. Just remember you pay, we play:)

Right now the equipment is

I wanted to build my own excavator but I do not have the knowledge of how the components work like turntable and undercarriage. My thoughts on this excavator after reading a lot of others are something to play with and over winter hope to build my own. I may use parts like tracks and arm. Things that are difficult for me to make. And I have some immediate work for a digger. :). Initial thoughts--wow this is cool!! Later thoughts-- need better bucket, very slow track speed and hydraulics are much in need of rebuilding. (Like rebuilding from scratch with different materials and design). 3 of the 4 cylinders leak, weep and just ooze fluid. Need a filter also. But,,, I am happy with having something rtr that I can work. Oh and need to change controls, cat control is what I would prefer. I don't have a funmotec (ideal digger for me) to compare but with some tlc and a bit of work I think this ex is a fine addition to my growing fleet of overpriced waste of money toys as my wife says :).

[Cooper]

A wile back over winter I obtained a tamiya areomax. Had to go with a ford as my last name is ford :)!! After some thought on building a circus attraction heavy hauler (going to build a cage trailer to stuff the cat into and charge $ .05 for ticket to see worlds largest tiger 1:14 scale) lol!!!! Or a dump truck,, the dumper won out but I can still build a rolling cage and stuff cat into!!! (At least I'm not into airplanes or the cat would be in serious trouble!!).

Something like this.

Going to see if I can use this style of lift.

And thanks to this forum I found figelli actuators instead of having to build a hydraulic setup. Some testing will revile if it has enough power to lift a overloaded bed.

[avel]

HA! You had me going for a second. Congrats on the excavator! Also glad you are finally putting pictures up of your truck build. Have you cut the sleeper off already?

[Cooper]

Yes Avel, sleeper is off. I have to get some styrene. I think that is what to use ,? I'm also looking into the reduction unit for these trucks. It's like a race car!! For what I'm using it for I would like slow hauling speed. And I'm going to have to beef up suspension. As far as axels and drivetrain, I'm just going to use stock till something wears or breaks.

Welcome to the forum and nice fleet you got there
My buddy got one of the excavators and he loves it he turned it into a linkbelt 700 he messed with the radio some and turned the pump down and he hasnt have any problems with

[Cooper]

Cool a new forum!!! I enjoy how you other guys have rolling threads, always having some work or working on something. And now that I have a prospering excavation company I feel right at home!!! I should have a landline internet connection this week so till then the videos will have to wait, at least the hd ones.
Got a cheep tool tray today and the company mascot had to help!!

And did some more work on removing the fishpond waterfall box. This project should take some time as it's is about three feet from top to bottom. Front is completely accessible but sides are tight and back is impossible to dig. A 2" hose feeds the bottom of the box, I forget if its from front or back or side, but I'm going to dig that up also. So far I have been digging and piling dirt for the dozer to push away. That is working for now.

In the last pic you can see I unearthed the input hose. It's a 2" line and now that I have located it I'm pretty sure in connects into the back side.

[Cooper]

I do have to correct my initial opinion of the bucket teeth. As I said it needed new teeth. I hade been digging in a rooted area and dirt was getting packed/clogged with dirt and roots rendering the penetrating force ineffective. After stopping and cleaning the dirt out of the teeth they penetrate the rooted sandy wet soil quite well. But the bucket is still just a thin steel construction and in heavy force you can see it flex.

[Dieselchopper]

Took me about a week to build a heavier bucket. Build a few buckets and ripping tooth. Seem to run the bulk bucket most.

[Cooper]

Will do dieselchopper,

Some more work on the dump truck.

I have the servo (actuator) on the gear channel but with a disabling mix replaced with a dial pot. Flip the switch on gear then any position of raising dump bed with the rotation of dial. Or dial all the way up and then when gear switch is activated bed goes up whole way.

http://i1357.photobucket.com/albums/q750/cooperford/D5A8D377-D946-419D-9EED-FEB4479A32D4_zps9pyvysen.jpg

I am still not sure of a wet heavy load will be too much for this little actuator. This was just a vise I had at hand. Solid steel, it's got some weight. I did place a 10lb weight on the farthest spot on lift arm. It did lift it. I'm making the bed and sides from 1/4" plate aluminum. I'm going to try and cut as much weight by milling in the side profile, leaving the vertical supports. And same with bottom.

[Cooper]

Awsome RW you work fast.

Grreat way to waste $$ ..Congrats on the New EX

I got the one that you just plug into your receiver. So it's probably 6-7 volts. I'm not sure. Makes it real simple. It is basically just another servo.

[Cooper]

Did some more work on the dump body and lift. The servo I purchased was a L16 50mm stroke and 63:1. I'm just not that confident of how much this can lift. Options are, I may get the 150:1 actuator that will have more torque/force. (Newton meters or whatever it's rating science is :). I need to figure box size and weigh amount of dirt for the volume. That way I'll know before I get too far into it. I was looking at a way to increase the initial couple inches of travel. That is the most demanding part of the stroke. I had some cheep clamps laying around that I pulled the springs out of. I'm using them at the back pivot to help unweight the load. They apply most of the force from all the way down and then gradually let off. Just what I was looking for. I have two installed and a place for third if needed. The empty box will still have enough weight to settle down.

http://i1357.photobucket.com/albums/q750/cooperford/4616544C-53D8-4ABA-A957-9821061F005F_zps0crasrtt.jpg

That is one of the larger springs. I have two of the smaller one installed.

http://i1357.photobucket.com/albums/q750/cooperford/71F59F89-60CD-4CFC-A0DA-F7D1CE868ECB_zpslkslnxr5.jpg

And if needed they can be cut down so nothing protrudes. Even if they are left that way none of that area in in conflicting with other things.

[Blender]

Well done. Excellent use of torsion springs.

[avel]

I have been thinking about the same thing, adding springs to help with that first part of the lift. Nice to see someone else doing it.

[Lil Giants]

Slick idea with the springs... :cool:

[RCLogger]

Great idea. Wish I thought of that a long time ago.

[Cooper]

This is what I may turn the 4200 into. Looks most like this.

[Izzy]

some ideas - comments

do you have enough room for 2 firgelli side by side?

also - go with 3 springs - maybe the firgelli can pull the box down

[Cooper]

Izzy, I may shorten the arms, it has more than enough dump angle. Probably about 80 degrees. I think most of the lift weight is my lack of correct placement and location of lever forces. My redneck engineering may need altered a bit :).

Here's a vid of the d11. Sorry about the aspect, I'm still learning on these darn electronic devises. I'm use to carburators not computers!!! Ya know when things were fixed with tools not laptops :). Anyway it will get better. Have about 6 hours or more on the d11 and no problems. Running at 20 bar (need that for the tilt cylinders).
http://youtu.be/u3p1UB7QO_E

[Cooper]

Ok I need to do some work on the 4200. Leaking cylinders are down to just the bucket. I may take apart again. I think the pump is leaking, kept noticing oil inside. That may also be from some spitting out the vent fitting they use. But I had a towel stuffed around that so I'm pretty sure it's something in pump. In the pic there is oil everywhere but that is because I tried to jockey up onto two 4x4s and forgot about the tank and breather- didn't have the hydraulic power to lift itself- because I emptied the hydro dank!!! Lol!!!' Just going to do some revamping for now. Wintertime will get a whole new machine.

Going to eliminate the on/off switches for drive and turntable esc's. No need for um. Add filters. Re rout hoses to be more finger friendly. Possibly make a new tank but at least get rid of the vent. Not eliminating it but changing or running a hose to outside at least. Possibly relocating everything to help battery placement. And making some sort of user friendly hood. Oh and adding some on/off switch , possibly consield in cab. I have anniversary this weekend so I have about two weeks before she needs to be running.

And I have to make some new pins for boom and arm. These keep coming loose. They have threads into both sides and I don't want to over tighten them to make disassembly trouble.

Question for you guys, this is the pump set up they use,

It is four valves. But only three active cylinders. And the way they have it plumbed. Are they using the first valve to deadhead the pump and then mixed with other valves when input applied to sticks? I don't know much about these but that's not how I did the dozer. Would it hurt this style pump to change around to prv being the deadhead and then gaining another valve for say a thumb? And if so what advantage is this configuration? Or is a disadvantage ?

[Supermario]

Sorry to hear about your troubles with the excavator Ralph. I've got about 5 hrs total run time on mine and all has been good. Cylinders dry and no leaks in the body. I did have my first hiccup yesterday. The relief jammed and suddenly had so much power the stick function pulled the whole machine like there was nothing to it! After it cooled down things went back to normal.

Anyway, I'm a little embarrassed I never noticed myself but after seeing your post, what the heck IS the 4th valve for? :confused:

I'm off to the basement......:bounce:

Mario

[avel]

Easy way to find out would be to disconnect the pump and watch the servo's as you operate the hydraulic controls.

Have you had a gauge hooked up to check your operating pressure?

Also, on the RC4WD site they have the Pressure Relief Valve for sale but the specs have it only going to 72.5PSI. But the info sheet for the excavator says it operates at 290PSI.

[Lil Giants]

Apparently the purpose of the 4th valve is to redirect oil straight to the tank if no other valve movement happens. It keeps the oil from travelling thru the prv causing the pump motor to strain unnecessarily - conserves battery amperage.

[Cooper]

The valve that the pressure enters has a mix to activate it with each of the other valves. Must have it slightly open as you can see fluid flowing when no stick movement with pump running. I'm assuming the mix opens the (input) valve more as the other valve activates. ?!?? If that servo is disconnected and not working then the hydraulics don't work. Unless the ports on the inside are different I don't see why it couldn't be optioned to re plumb / re radio mix and end up with a forth valve for attachments (thumb)?? I don't know how far I will explore this at this time but if unanswered by winter I'll find out. :). Wonder if anyone else knows how this works or why they choose to run this way. To me it seems like more work all the way around and harder on the pump. Unless ,,,,,, maybe it is acting like the prv only diverting flow until stick input is required then pressurizing and then relying on the prv to handle excess pressure? That seems logical. That make some sense to me with being able to see the flow in the clear lines.

[Cooper]

Wish I would have refreshed before I just posted that!! :lol:

[Cooper]

And speaking of battery life, I timed the dozer over the weekend. Had 1hour and one min on an 8.4 amp battery!! (8400mah) still had 13% left!!! Was running ripping and long passes.

[Cooper]

Well just got back home and found a solution to my hydraulic leak,,,

Lol!!! Stoped at a civil war relic place (yea I know , I didn't think they had frag granades back then either). Lol:). Just couldn't resist getting some to throw at my vet buddies!!!

[tracksntreadslou]

Lol..Looks like a very good solution..Im sure with some upgrades you will end up with a great machine ..With your skills I can see a complete set of new cyclinders in the works if need be..

Thats awsome runtime with the dozer ..Yes an awsome build for sure

[Cooper]

Lol, thought somebody would get a kick out of that :). This forum is and has been a wealth of good information!! Ya know I've been "tinkering/improving" things all my life and yet have had a chance to purchase anything that I deem as perfect . Not complaining as I have purchased many things good and things cheep. Like some tools, cheep tools for the shop but good lasting quality expensive for the home (or my no one else touch) toolbox. And if I'm ignorant or not sure how much use something will get then then I usually get the less expensive to get by stuff. As far as the 4200, I think it's a pretty good platform, mind the price. Sure I wish I would have got my top pick of a funmotec ex, but twice the price too. And from what I've been gathering bits and pieces of all of these priceless "toys " need some personalization. Not complaining about anything as I'm rather grateful that I have the ability to be able to sit in my umbrella covered lawn chair with arm rest holder containing a ice cold beer while running some heavy equipment to do the yard work. Just need to time the pee break with battery swapping. Lol!!!!
Yes, Lou, come winter I plan on some more personalizing, new cylinders, metal hoses, shrinking cab to be more 1:14 scale, bucket, track motors, engine hood, decals,,,, ya know stuff to make the customers feel as though I know what I'm doing with their money :)

This is what I've been working on, it's the waterfall box from fish pond fill in project. It's rather fulfilling doing the work with these toys. At first I was thinking, boy this is going to take a long time to do. But now I've found it rather relaxing after work to come home and "work" some more. And now I look at it as boy I hope I don't get it done too quick!!!

http://i1357.photobucket.com/albums/q750/cooperford/bf0358698fb539ab7cd2f1340e995bd5_zps7b50a1d7.jpg

[Cooper]

Oh and I did instal a pressure gauge on the ex. Some of the leaks were probably due to high pressure. Like 400psi!!! Yea, had to back it down a tad,,,,and that was after I initially turned it down some from day one as I read some people say they might not have pressure set right from factory. And the pump developed a leak, found it to be the motor side of pump shaft had been installed backwards. Allowing only one of the bearings to support the gear shaft. That resulted in the premature wear of the rotary shaft seal. The shaft has pins at either end, one for motor coupler other for gear lock. The holes are just a tad different spacing from ends of shaft and I assume during factory building this was just simply overlooked and a simple mistake. Keep in mind those who are actually building these are long hours, low pay, individuals that really don't have much interest in them. Kinda like the 16 year old kid working at mcdonalds, he really doesn't care about how many pickles or how they are placed on your Big Mac. He just wants his pay check to blow on some rc toys!!!!! Lol!!!

[ihbuilder]

now that you dug all around it , hitch a chain to it and the D11 and let it rip :D

[Lil Giants]

And now I look at it as boy I hope I don't get it done too quick!!!


I've been trying to avoid that conclusion myself for the last couple yrs with trying to dream up new things to keep busy with... and it's getting harder to maintain employment as my equipment keeps getting bigger, although I can't imagine ever going back to those 20ton machines I started with. :eek: :p

We lost power after a strong thunderstorm. Luckily I had some batteries charged up!! This is right after a heavy rain came through, it's muddy and stickey but got some material into where the waterfall box was.

This is the first video of pushing some dirt after the thunderstorm.

[Cooper]

Had some changes on the 4200 excavator, as I mentioned in another post I installed a gauge and filter to the system. For the time I have, (winter will be a complete overhaul) I placed a small particle size disposable filter inline between tank and pump. I thought a suction would be better than pressure if it gets clogged. And ease of location. Now I don't really know what foreign particles were in the hydro system but seeing some stuff floating by in the clear lines I just wanted to get something inline. Digging had been going well and strong aside from a leaking (dripping) bucket cylinder, . She has definitely been getting worked and used, bucket is bent up, scraping teeth on side of bucket have been bent back several times, ect ,,, but it started to get slow stick movements after about five to ten min of work. I would turn off let sit for a min, then back to digging well again. Every time a bit shorter, I thought the pump was wearing out already. Realized it's just not getting enough flow from filter. Removed and wow it's like new again!! (With the leaks :)). Just curious if location of filter is for a purpose. I see most having filters before entering the tank, I was thinking of pump protection and right before pump would be best. Just preference or is there something I'm not aware of? And I'm also under the impression of never having too much effective filtering for hydraulic systems.

[apfubar]

Mine is on the return line... If you put it on the suction side of the pump, the constriction may slow the draw of oil into the pump, and may cause cavitation...

That's my 2 cents...

Cheers,
Andrew P.

Yea, that's what I figured was happening. Seems like the system had a lot of foreign debris in it. Quite a bit of sparkle to the oil that i back flushed from filter. Well I'll upload a video of digging today later tonight. I was digging the first of the steps for a retaining wall. Everything was fine and towards the end it started acting up. Pump revved up tracks started self propelling. I figured ut-oh, must have had some water in esc or radio from the little bit of a shower I got caught in the other night. Loaded her up and to the shop, luckily the mechanics were still there to work on her :). I think I found the problem, in a haste to get up and running I was stuffing two pounds of crap in a one pound bag so to speak. I replaced the screw terminals on the esc and battery leads with bullet connectors. Usually I have excellent solder joints but not using my normal tools and in a hurry I believe I may have made a cold solder joint. And that may have affected radio as well as shorted the bucket servo. Or it did get wet. I plugged a battery into the receiver and it seems to be working fine so that pretty much points towards a bad joint. Yup, slacker mechanic on duty that day!!!! And I'm usually the one that everyone else brings their parts to be soldered!!! Figures, right, plumber always has a leaky faucet at home!!!

Some more digging, I had a servo go bad and the quick replacement I had was same size and shape but reverse direction. Not knowing what the mixes and navigation on this radio were I just choose to learn on the fly and remember bucket stick was backwards. So if you see the bucked curling or dumbing it's just my brain not listening to my hand :). Or vise - versa. :)

I can actually help you with that radio problem Ralph.:bounce:
Unfortunately I already have way too much radio learning and reading experience in the last few months:eek::mad:
Reversing a function is simple compared to a mix problem which I'm having trouble with. And thank you for posting the question about the fourth valve. Made me realize my radio still ain't working right:(

I'll send ya a pm with a step by step how to reverse a servo.

[Cooper]

Thanks Mario, I don't mind getting into setting up radio but I haven't been too familiar with that particular radio. And hearing about others :). Accidentally hitting something I didn't want to chance not being able to dig. I ended up getting a couple off amazon as backups.

Finally splurged on a $20 cart to make the 50 foot trip from garage to work site a little quicker and easier. :). Kinda weird that we spend $400 on a hydro pump/valve and not spend $20 on something to make life easier :)!!

I couldn't resist, I got the brushless drive motors for the 4200. The stock motors were fine, a bit weak but I didn't have any problems I just want to find out if they are faster.

Removed one side for ease of wire routing. I don't have a pic but the brushless motors inside the new drive hub must be small. The lead wires were like a needle. And they didn't give any more wire than what's needed. But plenty of extra wire from the new ring. It was just a hard place to solder and have shrink wrap on wire. Oh and anyone else getting these, there is a left and right!! I found out right after I soldered and put the heat shrink on that the holes don't line up. :(. I really hate when I do things like that!!!

That sounds awfully familiar :thinking: :D I'm finally making myself fit all mechanical components together 1st before do any painting, wiring or hyds on new models or upgrading old ones. ;)

[Cooper]

Oh s#£t!!!! It would have been really nice if they would have said the new esc's were only rated for 7.2 volts!!! Dammit!!!! Why would you sell a (upgrade) that you have to downgrade batteries?? I wired everything up and had the excavator up on a block to check direction of tracks. Plugged in 3s battery ,what she runs on, and wow!! They were like little race excavators!! I was really shocked to see how fast the tracks moved. I knew they said faster speed but it seemed too fast!! Started to smell that magical electric smell, and knew right away something wrong. Unhooked power checked (multi-meter) voltage and inspected everything. And the one esc fan was like a turbine, I figured I might have a bad esc right off the bat. Messed around some more and finally no motion!!! Looked up the esc on internet and then I found they are susposta be run on 7.2 volts!! 2s max!! Yup my 3s input cooked um!!! Guess I have another lesson to learn, no spec sheet= turn on the computer first and find out what you are dealing with!!!!! What a crock!! Oh well I would have had to switch them to 3s anyway. Yup, I just looked on the site to make sure I wasn't putting my foot in my mouth, excavator battery 3s, specs on esc from looking them up on internet, 2s lipo!!! Kinda pi$$ed!!

[Supermario]

Awh man, that Really sucks! I was thinking about the new drives. I would have done the same thing and powered with the 3s.
I feel for ya Ralph.:(

Mario

[Lil Giants]

The 2s esc's would have been fine on 3s, you could have just dialed back the EPA in the radio.

That china crap with no thermal protection.

[Cooper]

Some more d11 work, I changed the locations of pins for the front crossmember connecting the left and right track carriers. It lessened the amount of torsion the tracks could move relative to frame. And lowered fron end about 1/4". Handled a bit better giving the tracks a bit more traction. Even though it's muddy it still had noticeable more traction from that little change. Guess those engineering changes from one model year to the next have some merit!!! Lol!!

I know the light housings may not look scale or real good but I have had this box of LEDs for several years and the bezels to go with them, figured this would be a good way to use them. As I remember I had to get them but don't remember what for!!! They are bright white 10mm LEDs. Should light up the way pretty well!!

[Lil Giants]

I don't think anyone here is anything too anal about perfectly scaled, whatcha got started for lighting looks great so far! :cool:

[Cooper]

Yea I hear ya, I have the empty sockets at the steps of the cab to install lights in. As for reversing lights I have seen where they mount on the side of the rollover structure. That gives me two more to face forward. I'm thinking of a total of 8 forward and 4 backwards. These LEDs are pretty bright, I forget the forward current and lumens but rembember they put some good light out. Going to have them on a switch via radio. Also have to get a sound system for people to enjoy when I get my but to some of these gatherings!! If my wife would get her rump in gear I could have been able to attend Brownsville in the motor home this weekend. By next Wednesday we should have all the paperwork done and then I just need to get two new sneakers for the front end. We acquired her grams motor home that they hadent used for a couple years. It's pretty new but got cought in a flood. Had water over axles but not in cabin. I'm taking it to get a good go-over from the dealer soon. That's going to be my heavy hauler for the toys to attend some relative close events. :). Who else do you know that can haul a d11 with a class a motor home ?? Lol!!!

Lol!! Great Dane construction co., "the more we dig, the more you pay!!,,,the more you pay the more we play!!"

I think I have another servo go bad, the machine gets a mind of its own, reves up tracks move,,ect,,,, last time it did that it was the servo cooked and somehow was messing with radio causing the out of control. I'm definitely enjoying the little guy, but these tower pro servos are not lasting me. I still think there is a radio glitch but I'm sticking with it till winter overhaul. Anyone know of some quality servos of same size as a tower pro 995, digital metal gear? Might have to have a look at hk stuff.

[ihbuilder]

try the hitec 645MG

[Supermario]

Now that you mention that, I've definitely had 2 or 3 radio glitches now with mine! No servos failed yet but maybe cause I got too much paint on the bucket still ;)

As always, I was shutting off the pump while hauling with the dump truck. Then when I flipped the pump on it was running but I had no hydraulics. I adjusted the dial for the 4th valve and couldn't hear it move. Figured the servo failed. It was 10:30pm, I just packed things up and called it a day.
2 days later I fire it up to see what's going on....all good!:eek:

A few days later, starting and stopping pump, suddenly nothing again. Turned radio and hoe off. Plugged back in, flip the switch..... All back to normal?:confused:

[Cooper]

try the hitec 645MG

Will do thanks :)

[Cooper]

Mario, I'm not sure but,,, maybe someone els knowledgeable can chime in. To me it seems like some oil may be (or had been before leaks stopped) infiltrating into the trim pot inside the servos. The one I replaced had a clear malfunction visible on the circuit board. It was ever so bit charred on one of those little circuit thingies. And pot was also wet with some oil. The second one that failed (I took apart but not cleaned and tested yet) did not have any visible scored areas but trim pot was again wet with oil. I know the gears internally have grease but until I take a new one apart I can't compare on the viscosity or amount of grease, and if any is around the pot dial shaft. I don't think the little trim pots in these servos need or have any lube on them from factory. I may be wrong but to me it seems like grease or oil would compromise electrical contacts in them. Sooooooo,,,, that may have been my problem from the get go. But I still can't understand how the servo would back feed some sort of electrical signal into radio receiver. Kind of makes me double think about using the flysky radio system for any air use. But I only have micros and park flyers that we dog fight with a small ribbon on tails. Try to wreck them but it's hard!! One thing I have not looked at is to see if any leaks are around the rotary valves in the actual valve block. Gonna keep running her hard till ground freezes with efficient quick repairs until winter overhaul.

[Supermario]

I noticed early in the operation of mine that the relief valve leaks past the set screw threads. ( I found it right away because I had the thing running at max speed and the 4th valve wasn't working so , the relief was " busy " all the time:)

Even now , after setting correctly , I still get a little leakage. I placed a towel under it to capture the oil. I think I ran 3 or 4 battery cycles before the towel was getting oil soaked.

Anyway, I bet that leakage is what got into the servo? It's the only possibility:confused:

Here's a pic, notice how the relief is directly above the servos? ;)

[Cooper]

I did stuff some soft material (ear plug pieces cut ) into the servo shaft where there would normally be the arm screw. These tower pro servos have a hallow shaft, it could have easily wept oil into the servo that way.

Now one of the centering spring boards in the radio broke. It popped off the rocker pin before and a quick fix. I may not be the only one but sometimes when I'm prying on a rock or root I find myself pressing rather hard on the radio sticks. Yea, at least I'm not sticking my tongue out, holding my breath and rotating my body the way the excavator is moving. :). Lol!!

I try to post work pics for others to see, maybe it will help someone. The track motor loosened up, the two Phillips screws removed to get to the internal screws attaching to motor. And I found a way to remove tracks painlessly, I remove the outside housing then the tensioner and wheel can be removed allowing track to be removed without removing any track pins. Only draw back is sometimes it's a trick to get the roller shafts lined up for re installation.

I was going to build my own voltage reducer circuit but found these for just a couple bucks. They are for dropping voltage to the upgrade track motors that I had problems with previously. One for each motor, rated for three amps. I really doubt the tiny brushless motors in the upgrade kit are able to sustain that for any length of time. The motor lead wires are very tiny about a pin thickness.

But it was rather funny looking back on the early 90's.

[Cooper]

I abandoned the dump truck project as I purchase on from a fellow member. Now I can keep my haul rig. I made new frame rails and 4-1/4" shorter. Basically the length of the sleeper. I'm wanting this to be more of a hauler, maneuverable truck. To me it looks goofy but I'm use to seeing the sleeper cab. I cut out the middle of the side skirts also. I may not have the smoke stacks there. I'm going to still have tanks, at least something to fill the void behind cab. And planning on a flip open body for access/battery. With smoked/tinted windows.

That is sweet! How big is the print area on that? 5"x5"? Staples sells them here in Canada and they have come down $300 in the last couple of months...Me wanty:D

[Cooper]

Yes another addition to the garage shop, although it's in the living room!! Thought the wife would say it smells of burning plastic but it is not even noticeable unless you have your nose to the build plate (yes I did) :).

Yup print area is about 5x5x5 close. I just printed a part that was 130mm wide. Was making a plate for radio and esc to span the tranny with a vertical area to tie in the back of the cab on the areomax. Bolting onto the frame rails. It was the first part, I did have the edges warp upwards during the last 20min of print. Only let the bed warm up 15min and should have longer but dammit I wanted to see it work!! Figured there will be some learning parts bin :). My biggest hurdle is the design software, using autodesign123d (I think / without looking). Figured I'm sure I will be able to get what I want made by using shareware and not $$$ cad software. At least till I know what I'm doing and how much I use it. Have to learn a different way of designing now. With the milling and lathe I had it in my head and only had the measurements written. And during the build I could remove part test fit/tweak ect,,, now I'm realizing how important and useful plans are :). My tape measure and calipers use to be a sharpie. Now I think I'm actually going to have use a ruler and calipers. As I have researched a lot from others once you get the hang of it , it becomes easier and very useful in the shop. Been pretty busy lately but will update regularly.

Printed my first part, it's just an idea and will need refined. I'm planning on adding more but this will bolt to the frame rails. The cab is going to be hinged from front bumper and this will allow some sort of stop for the back of the cab. Also the radio and esc now have a place to sit, one on each side of the tranny. There will be a shelf above motor to hold a 5000mah 2s battery, that too will be printed (I think?, at least the frame work for it ).

[Lil Giants]

KOOL!!! :cool:

You've already proven your high level of skills doing it manually with lathe & mill... I'm sure this will be a snap for you too. ;)

[Cooper]

It's posing to be a steeper learning curve than any milling operations I've had to learn!!!!! It's a different way of visualizing a part to build. Ya know needing measurements and an idea of what the finished part will look like before it's built. Kinda opposite from what I normally do. Lol!!

What 3d printer is that?

[Cooper]

The printer I have is afinia h480. Another member on this forum had a thread regarding printers. He was very accurate in describing the afinia / octave printers. They make it more user friendly in positioning and printing. You don't have to incorporate any support structure, the software does it automatically. And I value others opinions who have results the speak for themselves. :). For me the hard part is learning how to design parts and learn the software. Just need more fiddling time :).

And look what was at the door today, my first truck trailer!!

Some more time on the heavy hauler, esc / rx tray installed. Originally I wanted to make the cab hinge at front grill but am rethinking of using a completely removable cab. Magnets will hold cab onto frame and electronics (lights ) will be getting power from a simple contact tab. I haven't seen anyone do that before so I figure I'll give it a try. As lights on cab will be like 5-7 volts and not much draw. That eliminates me messing with a hinge setup and will give full access to battery. I still have to make the battery tray and figure how to fill the void, fake tanks? Flat enclosure between side skirts and frame.

For the animal lovers!! Rehabilitation of natures seed planter is going well, he was a little groggy but that did t last long.

I keep flip flopping with the aeromax. Hood hinge, magnets, ect. Playing with the printer has definitely made me think in a different manner. Good I think but designing hasent been my strongpoint!! So until I have a good direction of what I'm doing I'm going to quit saying what I doing. I'm changing my mind more than my wife does! And just can't have that happen!!! Lol!!!

This little nutt eater has some beefy body guards!! Only problem is that they may not be as loyal and reliable as needed!!! After the cat realized it wasn't a toy he doesn't want much to do with it!! Even had supervised cat rides and the cat just walked away!! But he does hunt, so in reality we will be cautious with him I'm sure if the prey drive kicked in he would definitely try to eat him!!!

Version 1 & 2 of the frame rail hood hinge I've been working on. Version 3 should be a finished product. This is what I love about this rapid prototyping stuff. Plastic is cheep ( vs aluminum) I can alter it in a matter of seconds, reprint. While waiting for the print I'm free to pester the wife, dog , work on something else!!

And the battery tray. Hood flips up, battery is accessible by a simple rubber band across top. From what I'm use to I would have to have several Velcro straps and padding around battery so these trucks are easy!! Not too much off roading that a rubber band wouldn't hold down :)

Lol!! That fat little ba$$tard has no cat like abilities what so ever!! We sometimes refer to him as handycat!! Can't jump, has to jump (fake try) onto the couch when we are watching but is on counters in morning sun!!! Doesn't like other cats but likes dogs, hates catnip but eats fallen dog food! Loves the car and riding on (or in) any of my toys, even taken for hand truck rides!!!

Getting ready for paint. I'm trying something new, I'm not using a adhesion promotor on the plastic but instead I soda blasted all plastic surfaces being painted. Just enough for some traction for paint but not gouging surface. This is the first time in trying this so we'll see how it works. I am using a sealer base coat.

Final coat. Depending how durable it feels I may not clear. But it's turning out well so a clear is possible. Probably a urethane clear. I don't have any experience with this type of plastic, anyone use clear coats? As I didn't really seal or coat insides and don't know how a urethane will react. Can find out but figured I'll ask, as I will be using a test piece.

And what a better time to start another project, getting back to that dump truck!! Building a 10wheeler. All drive axles. Pic in background is what I'm aiming for, close.

Purchased a rather rough shape dumper a little while back and quickly realized it would be a parts truck. Some left overs from aeromax daycab will help also. And this one is going back to my original idea of hydraulic lift cylinder. Have the one from magom(?). It's pretty small and uses 3mm tube. I think like 12 bar. And no guessing or math on this one!! Going to build it and then see if it's got enough pressure to lift a rather overloaded box!! Yup that good ole redneck logic!! (If you don't know how to fix it ,, tear it apart and look at the left over parts when you put it back together!) lol!! :)

I did get a trip down to the pit but no video as it was too dark. This is my first rig and I don't know what to expect but have followed many others advise and threads. I quickly found out that any imperfections in the dirt road stopped the truck. Going down was easy but kept getting stuck on the way out. Now it's making me rethink the dumper build.
http://i1357.photobucket.com/albums/q750/cooperford/7F21E5EE-A660-4D8B-A9C5-D4A5D3A06796_zpsjlntgjjx.jpg

Ok which one is better for dirt roads and uneven surfaces? Axles with lockers or having front wheel drive? Obliviously front drive with lockers all around is best but I have rear (2) and front drive axles for the dumper build. But would have to purchase locking axles. My thoughts are for building the Aeromax dump truck with lockable rears and just stock front. Figure if it gets low on traction I can lock and still be able to have a good turning radius when not locked. Is that what you guys are doing?

[steamer]

Two things I would suggest are, six tooth pinion gear on the motor shaft, gives you way more torque. and go back on the rear end rigging and loosen all the hardware bolts so the axles will articulate better. If it's too ridged back there you can get stuck most anywhere. One more suggestion is softer more aggressive tire tread and super singles on the front. The Tamiya tires just plug up with sand and are too rigid just like your last picture. RC4WD tires work well on mine!

[Supermario]

Hey the truck has a vibration in the tranny? Common with plastic gears? Just ignore or should I look for bent shaft or messed up gears?

I had a similar problem with a noisy tranny. It wasn't improper meshing of gears. Turns out the pinion gear set screw was contacting the spur gear teeth. I'd check to see if that's the problem.

Mario

[RCP57]

I was super disappointed with how easy these trucks get stuck last year when I got mine. Coming from all 1/10 scale equipment that is WAY heavier and runs tires nearly twice the size, I guess I should have known but I was still like WTF? Anyway, at the urging of some friends I locked the rear axle to try it and it works much better. I just used hot glue and it is holding up fine so far, the best part being that with greasy gears the glue doesn't stick. It cools and takes the shape of the teeth but the pieces just come out when you take apart the diff without any fuss(I didn't have spare spider gears to use). Chaseracer has both axles locked permanently in his Autocar dump truck and it still steers fine loaded on dirt. I will be locking the front tandem in both my trucks too in the near future just to try it. My Hayes also gets better traction than my KH because it has my own springs and the shocks removed. Like Rob said, if you tighten everything up properly it won't articulate.

I also had the same issue as Mario with a smaller pinion I swapped on. I had to shim the motor back for clearance so that the set screw didn't hit the driven gear. Luckily for me I remembered his experience first and shimmed the motor prior to running it. May not be your issue but it's worth a look.

Cooper, if you haven't read through LMACKATTACKS build thread on his ten wheeler dump truck it will help you decide how to set up your dump. http://www.rctruckandconstruction.com/showthread.php?t=7706
I drove this truck for about 2 hours at the RCTandC spring meet and had a blast. It would go just about anywhere in the sandy mixed dirt. I'm currently building a dump using a TLT front drive axle with a scale 72.5" tandem spread based on a Hendrickson walking beam suspension. The steer axle is locked and the rear rear drive is also locked. It will have a scale 19' bed. This was based on things learned from LMacks build and the spring meet in Ill.

We need more animal pictures in this thread!:cop::lol:

Sorry forgot to say nice job on the Areomax! I like the color.

[Cooper]

http://youtu.be/ArWMPF2HEYY

Hey trucker, it's not pictures but it covers all my animals (I was happy with one each but I caved into wife) and the Aeromax finished. I'll get to that thread, thanks!! It's what I want, as I'm planing on running the dump in dirt 99% of the time.

And I figured on beefing up the suspension. If I go with the front wheel drive I can now make new springs heavy duty. I got a sheet of spring steel, easy to work annelid, just have to heat treat when done.
http://i1357.photobucket.com/albums/q750/cooperford/021D3667-C441-4F70-976B-E3D3ADC572BF_zpsqlluejqc.jpg
Bottom spring is stock tamiya, top two are test builds. I made a quick jig to accurately bend. And surprising that steel in its state is really easy to shear and bend. Same thickness as stock (22 gauge I think). Once I get the right length and eyes bent the other leaves will be easy.

[TRUCKMAKER]

Nice video! I might get one of the cats to ride but I'd have to put a cardboard box on the trailer for them to ride in! There are empty boxes in various places around the house if you don't throw them away as soon as you take stuff out they fill up with a cat. :lol::lol:

I bought F350 add on leaves from TamiyaUSA, 4 different lengths, in packs of 4 for about $4-6 a pack. Put them in the front and rear.

[Cooper]

4-6$ would be a lot easier!! I still like trying to make stuff too :).

I did a quick test on two springs I made, one heat treated and one not. I just used mapp gas to heat, rather quick to glow. I don't know what the exact target temp or what temp I got to but for what I'm doing its fine with me.

http://i1357.photobucket.com/albums/q750/cooperford/2EF80CF6-1475-4EC2-8872-C1CB24346319_zpsx0tbwohh.jpg

Clamped both springs and applied pressure at eye to flat.

And the return rate. Must have tempered some. Definitely a lot more spring. The treated one will vibrate three times longer than non. So I'm on the right track.

And another project I've been thinking a lot about lately. Very few multi stage hydraulic cylinders out there. And ones that are available are very expensive. So,,, one I don't know what I'm getting into and that's why they are so pricey. 2, too much work and don't scale very well. 3, I'm just too green and ignorant to know any better. :). 4, all of the above!! I'm going with # 4 and going to bite off more than I can chew. But I like the challenge. (At least that what I'm saying now.

Had to fire up the dozer today. Had some dirt that needed piled. And because we are a shoestring backwoods construction company we don't have a dump truck for moving any dirt. So the d11 gets to push up piles.

[Cooper]

Well I settled on building a single cylinder for the scissors lift I had originally built for the dumper. I wouldn't really know if it will work until I have it all hooked up and put some weight in the bed. Here are some pics of it so far. I will be removing some material from side of cylinder as walls are 1/8" . The bed will have plenty of dump angle, maybe too much.

Nice work Ralph. Can't wait to see testing videos of it.:bounce:

Where the heck is the pump/motor going to fit? Using a fuel tank style set up?

[Cooper]

That's what the plan is so far, pump to be housed in side tanks. I was going to eliminate a valve by using two pressure release valves. One on each line. When hoist reaches top or bottom prv will kick in if I don't stop pump. And hoist will be controlled by direction of pump. Basically be two loops and a cylinder in between. (Again that redneck physics kickin in) lol!!!

After eyeing this for a while I'm pretty sure I should move the pin at end of hoist , the one attaching to dump bed, closer to hoist hinge. To me it is too far and just going to create more force to lift. I could do the math and figure what force would be needed on the cylinder to lift X amount of weight , but no fun in that!!! As it is this type of fulcrum isn't really efficient but it is compact. And the further that bed pin is the harder to lift. But I have it as is and can do some tests (will video :)) to see how she works before having to do all that relocation. A touch complicated to get all lined up!! I have one of those little magom pumps and I don't know what condition it's in. Have to get to work on plumbing the lines for cylinder.

[RCTech9]

Good looking aeromax Cooper.

[apfubar]

FYI around the pump, etc... On most rc hydraulic tippers, just run the pump until it hits an electric limit switch.. Stop... The lower by reversing the pump... The limits are microswitches ... With a relay... Simpler than hydraulic prv's, and easier to mount.

If you want the details let me know I will dig up a wiring diagram and some part nos.

C

[Cooper]

Yes, send me some more details. As I have limited experience on limit switches ! Ha!! I never installed them just know to be using a s.diode. But some more knowledge is always wanted!! Thanks. I'm running on 7.2 volts (can change if necessary ) pump can run by esc or by switch. I guess that doesn't really matter. Thanks a lot.

http://i262.photobucket.com/albums/ii118/apfubar/Arocs/th_4E263838-1ADF-4590-B59C-3D2C939A6FB9.png (http://s262.photobucket.com/albums/ii118/apfubar/Arocs/?action=view&current=4E263838-1ADF-4590-B59C-3D2C939A6FB9.png)

The CTI PS4aT converts the single channel to up and down (two functions aren't used).

The two lines out of the CTI go through limit switches to break the circuit when the limit is reached(one has three in this case as the tipper is a three way unit).

These trigger a relay which handles the full current of the pump...

The relay is available from Scale Art.

Thanks for the info!!

Got the cylinder for the dump lift done.

Ok, got the cylinder working strong. Problem is the pump I was planning on using is shot! It sucks air. I think the seal on motor side is shot. Oil leaks out when under pressure and sucks air when retracting piston cycle. It is a magom small 3mm fitting pump I purchased with a dump of a truck from fellow member. (Really wish I received pics I requested before purchasing, oh well my mistake). Anyone ever take one of them apart? It looks like the pinion is pressed on. If so I question how much damage I may do in the removal process. Might bite the bullet and get the small pump like rc4wd has. Another question for you is how do you guys plumb for a dump cylinder? Do you use a servo and valve? Just plumb pump to cylinder on pressure side with tank on retract side? Just one simple loop of pump to cylinder without a tank? Limit switches to prevent over pressure or the whole boat with prv and valve?? I know questions , questions right??

http://umstech.in/search_results.php try 1 of these ( L 00 Y 0300 ) they're good pumps for dumpers . I'm just not sure if their shipping time improved :confused: copy/paste # in () into the search box on the site . the website is the same POS interface :(


Pressure side to up side of cylinder ( vent 2nd port or run straight to top of tank ) suction side of pump to bottom of tank . pump runs FWD to raise , pump runs REV to lower . It would be cool to put valve setup in like the real thing but not necessary .

[Cooper]

That's how I had it hooked up for testing. Had the hoses taped to a beaker full of oil. I know some say anti-freeze but I'm on the side of light weight hydro oil all the way. This is the pump unit I have removed from the dump of a truck I harvested it from.

I did tear down the pump unit last night and removed pinion from motor shaft without any harm. Some sealant along with a simple o ring is what they use for motor shaft seal on pump housing. Order some orings from McMaster and should have them tomorrow. .09-.07 by 1/16 something like that for replacement.

And someone else asked about the dump of a truck I purchased, some pics before it went to "Harry's you pull it" salvage yard ,

Only problem was Harry wouldn't take it !!!! Lol. Axles seem to be ok, little notchey but they go round. :). I ended up going with remote locker axles and a 4x6 drive train anyway.

[liftmys10]

Hmm I think your PM today was accurate in your description of the truck. Hope you get her all back together.

[Cooper]

I've been at a loggerhead with the dump body, make it out of aluminum? Or steel? I had planned on using 1/4" alum and milling the side profiles into the sheet, also making it lighter. A lot of work and not sure how accurate it would look. Steel, have the ability to bend but welding would not be able to make the seams look clean. Sooooo,,, I decided to try brazing. Went over the the barn and got the oxyacetylene tanks. Of course the acetylene tank was empty, ran over to airgas Wednesday and exchanged both. Thursday night got to play with the torch. Sorta,, oxygen gauge popped and acetylene gauge reading zero on regulator side no matter where bolt was. Made a trip to harbor fright as a cheep torch outfit will serve our rare uses at work. Also picked up this little torch,

And after playing around found out the little torch will be perfect for the tiny delicate brazing I'm trying to do. So after attempting to understand the basic principals of brazing I got my first weld,,

Once I found that magical temp and heat area I understood what to do. The second attempt

And found out not to overheat the flux as it glasses over and hard to remove. Some more learning and then I'm going to attempt to do the dump body like this. I was using 22guage steel. If I can find some slightly thinner I may use that instead. Would be neat to develop some scrapes and dents over time :). I would like to say I acquired another skill but I'm far from skilled!! Hats off to you guys that make clean detailed welds!!

[Cooper]

Started on the dump bed,

http://i1357.photobucket.com/albums/q750/cooperford/811A43F4-847B-4A5A-82BB-5567E44D12F4_zps0fivcxmx.jpg
Just tacked front and back braces to keep the bed square

http://i1357.photobucket.com/albums/q750/cooperford/717B4F84-F07C-4BF7-8DDA-C2F741E28D5D_zpsuylpzwbf.jpg

This is the side profile I'm making. The side spars were cut too long as I recalculated side height to accommodate some wood side rails.

http://i1357.photobucket.com/albums/q750/cooperford/BED804DD-95CF-41C4-BCA2-81448231BD5E_zpshpxjweac.jpg

And bottom ribs. These are tacked in place as not really a visible side (most of the time)

[Cooper]

Rain day!!!! Get some garage time!!!

Well I am far far farrrrr from being efficient and aesthetically pleasing in my welding skills!! I am tack welding everything I can then silver brazing seams that will be seen. After learning how to braze I may need to make this truck as a well used and abused dumper. I've managed to glob, over heat, warp, and just overall make a nice flat new dump bed into a beat and abused well used bed!! Well the drive train will be new and shiny:). Have to weather the cab now I guess. I know paint can hide and magnify but there is no hope for any paint job to help this. It's a learning project, I keep telling myself.

In this case pictures help hide,lol! It's not too bad on the brazing, once blasted I'm going to go over again and try and smooth out some high spots/puddles. But the little bit of warpage will just have to be delt with. On the second side I did clamp a heat sink (thick angle iron ) to the back side and was more careful of heating too much.

[Lil Giants]

I think you're being too picky RW, function before beauty is my motto. :d

Yes, I'm more interested in function. But trying to keep up with the other very skilled builders makes me realize I may be a fast learner but need more time than a week to develop skills like them :). I'm more so wanting the lift to be able to lift a overloaded wet clay load than some bumps in the bed. It doesn't look too bad after blasting. I bought a small cabinet for blasting from eBay. It's a fine addition, found out it clogs the filter easily then blows dust. Thought I would hook up shop vac to help pull particles into filter. Kind of funny as when I turned on vac it poped!! The gloves imploded and were rock hard! A little too much suction!! It was rather funny watching me play like a fish out of water with that!!! Anyway, some areas inside cabinet need sealed better and need to make bigger filter and clean often.

[Cooper]

And yes had to take a pic of the better area, lol!!

[Cooper]

Had some uphill pushing.

And some bonehead surveyor hod the elevations wrong!! So all that dirt pushed uphill had to be pushed right back downhill!!!

[modelman]

Cooper-your dozer seems to be working well now and the operator is also improving. :D Watching the videos I thought -if there were bulldozers millions of years ago, that's what it would have looked like with dinosaurs walking around them. :eek: I know the problems you are having with the brazing. I brazed my Marion shovel together and it worked good on small pcs. but the more metal added just turned everything into a heat sink and I could not get the metal hot enough. Some of your joints to me looked like they were not hot enough to flow the silver. Some of this stuff might be worth a try-
http://muggyweld.com/all-products/coolblue Watch the videos and yes I know they are trying to sell the stuff but it looks pretty good. I didn't find this until after I finished my model. Oh well!

[Cooper]

Thanks modelman, I'll get some of that and try it also. This dump bed is a learning process. I'm sure in future I will be making a better looking bed. Got some more done,

Clamp, position, check,,, reclamp, reposition, recheck,,,,,,,,

It did take a bit of time on the belt sander to get the back flat so gate would sit flush.

The piece left in bed was just to keep square. I'm using magnets to keep gate closed. I did incorporate a tunnel in the bottom of bed to accept actual gate locks if I want to try that. That might become another experiment and learning project. :)

Just in case I can't get bed up I made the dump cab cover removable. It's snug and might have to modify or remove paint if the paint layer makes it too tight. Originally I was planing on just having magnets but as I bent the metal it was perfect snug fit.

After blasting

[Cooper]

Problem I encountered with locking axles. At the end of the Allen tool you can see some slight scuffs, that is where the locker arm make contact with hoist .
http://i1357.photobucket.com/albums/q750/cooperford/F7E1B3B8-FDA9-4834-865D-EEB7642120CE_zpsfeykwvuf.jpg

After taking them apart and understanding how the little dog works to lock I may have to machine a new part or find someway to relocate. It will work the correct rotation if I were to have the arm on the bottom side of axle. But that may not be a great idea as any rocks or dirt could damage it. Have to play with it some more. Or would it be fine to have that (first drive axle) permanently locked? Would that mess up with turning ?
http://i1357.photobucket.com/albums/q750/cooperford/E7142CB0-366E-4632-B7CE-A2FEC473A89E_zps6nhczsta.jpg

[RCP57]

Your truck is coming along nicely! Chaseracer's Autocar has both axles locked all the time and it steers fine on dirt while carrying a load. Jason noticed it plowing the front tires once he had the pup loaded up though. All I can say from personal experience is that without at least one of the axles locked all the time they get stuck on everything while running empty!

[Cooper]

Well that is assuring, I think I will lock the first drive axle then. This is going to be run in dirt most of the time.

My welding skills are improving, brazing on the other hand,,, well need more time!!
After looking around at all the different dump trucks if came to the conclusion that any thing is a go. Many different types, styles, functions so I built a small side box to resemble a fuel tank. This is going to hide the hydro pump. I'm going to make one for other side that will have a small oil tank inside with fittings hidden.

Can't really see it but I put an x bend in side, light from camera hid the pattern.

[RCP57]

Lookin good!:)

You're right about the many different styles, shapes and sizes. Impossible to build one wrong! The more I look on the net for a certain style, the more I realize that very few are the same in every way even when they come from the same manufacturer.

Keep the updates coming!

[Cooper]

What kind of tire glue can I use? Plastic on back wheels and steel/aluminum? On front wheels.?

Working on second tank today. Wanted to play outside but windy and chilly. Plus wife took dogs so I've got house to myself-have to enjoy things when the pitas aren't here!! (Pain-in-the-a$$'es) lol!!

[Izzy]

Why glue? How about ruffin up the bead groove on the rim instead? I have yet to glue any tires on any of my trucks.

Like your dump bed - looks really good. Nice welds too on such thin material.



Izzy

[TRUCKMAKER]

I have a set of super singles that some one glued and thought I could change wheels, not happening! I would not glue them if you even think you'll want to swap wheels or tires.

[Cooper]

I just assumed they needed glued. Thanks for keeping me from the glue. Yes with other faster race trucks I always glued tires and just figured once they were glued they were married for life. :). Do you guys run foam in front tires? Reason I ask was this being a load hauler figured they would roll of bead fairly easily. First timer here:) limited brain cells!! The alcohol killed off all the weak ones and only healthy strong ones left, just not many ;).

[Lil Giants]

Air rifle BB's work best, not only do you get a stiffer sidewall so you don't peel the steer tires off turning when loaded, but also the added weight when empty helps the trk get around much better. The BB's in your rear tires will help lock your tires to the rims so the rim doesn't slip in the tire, get 'em packed in as tight as you can! ;)

I've found that locking the rearmost diff in a 6x4 works best so it doesn't impede on steering too much.

[Cooper]

Thanks , I've done that with rock crawler, and happen to have a large bag of leftover bb's to use.

http://i1357.photobucket.com/albums/q750/cooperford/64E70061-F437-4EE8-B5B2-E1EE615660EE_zps8vh296ou.jpg got a new pump, will hide in tank.

I was going to use the steel tank for the actual hydro tank but my solder skills are slightly better than my welding skills. To make a sealed tank. The small fitting on top is a breather vent.

[RCP57]

Is that the RC4WD pump from their dump truck? Looks like a nice small pump.

Great work on the tank! You need a TIG!

[Cooper]

Thanks for sharing that dump bed pic in other post! Yes I need a tig welder. Only problem is I don't need it for anything other than my toys. Have been looking around for a good ac/dc , I don't know much about what to look for, any suggestions? Would be used on just thin stuff, 1/8".

And yes I got a small pump from rcbrim, pump and esc, same as rc4wd. I'm sure pump will be more than enough. Still not sure about hoist mech but only testing will tell. If it doesn't work out I'll be pestering you:) for a box and hoist!!!

[Supermario]

You may not weld like Reg but you sure keep a good work pace like him Ralph :);).
The dump truck is coming along great. I wish I had remote locking diffs for mine. I have the rear axle in full lock and with a heavy load I notice a major drop in turning radius. The soft front tires don't help but I like the using BB's suggestion. I can quit wasting them trying to hit the black squirrels in the yard and put them to better use now. Lol.
I've never glued any of my tires. I've hauled my quad axle with 45 cans of BUD on board and never spun a tire so why glue? :D
Enjoying the build and can't wait to see it getting loaded and haulin dirt! :)

No problem. You think that you won't use a TIG for anything else until you have one. No smoke, no sparks... it becomes pretty appealing in a big hurry! I haven't welded much mild steel with it but I definitely think MIG has it's leg up on TIG with that. Especially if getting the job done quickly is important. TIG takes more time, gas and patience. My welder is a 225amp Lincoln. It will weld 1/4" no problem but anything thicker is a stretch without preheating. I also have a Miller Diversion 165 that I started out on. It was replaced with a diversion 180 I believe but it is a nice little beginner AD/DC welder. I think the newer version comes with a foot peddle as well as the finger tip adjustment. There are also a few of the 3 in 1 welders out there now which seem to be popular but I have no experience with them. Take this with a grain of salt as I am not a welder. Someone else on here could probably give you better advise.

[andyathome]

you need a tig!
I picked up a three in one tig a few years back it does stick ,tig and its a plasma cutter.
I have a large mig and I used to build my own 1:1off road race cars, got sick off all that dust from slitting blades, found a small miller 3 in 1 and haven't looked back , welds mild steel , stainless ect.
I would be lost with out it now, I built my dozer using the tig ( all stainless) and the welds are by far cleaner especially on the little things.

just my two cents.

cheers andy

[Cooper]

Well enough of the horsing around,,,

I've got a question, in the pics below my screwdriver is pointing to the track pins. They are made of brass and the track shoes and links are aluminum. I thought that the aluminum would wear first, not brass. But it looks as if the brass pins are wearing faster, faster than I thought. I brought the d11 in for the lights to be installed and gave it a good going over. I have noticed some slop in tracks and knew they were wearing as the front wheel assembly was getting further out on the track tension.

Now I had thought the aluminum would wear first, but it looks as if the brass pins are wearing out. That would be great as they are sooo much easier to make than the links!! Does this sound right to you guys? Brass going faster than aluminum? Over winter I will be tearing down and checking tolerances on links. Hopefully they will be acceptable and just pins needing replaced. Future pins will be made out of steel. Sound right? Ultimately I would love to have links and pins made of steel but that's a lot of metal splinters for me:)

My simple tensioning is holding up. I cover it with graphite, try to keep all the parts with a dry lubricant.

Have some wear on the track rollers. They are brass with steel shaft. I'm upgrading them from 1/8" to 3/16 stainless shaft and milling centers out for bronze bushing.

Enough room to replace 1/8" shaft with 3/16"

This is the amount of brass that will make up the rollers. I'm going to be using non flanged bushings, just press them in.

The paint for dumptruck. Again I'm probably going with paint as last coat and not clearing at this time. I did put my tail between my legs and admitted defeat on the dump box and hydraulic hoist. But,,, have some secret parts coming. Oh and reg, you shouldn't get any hate mail from my wife,, I just have to look forward to having four more furry feet sometime this summer!!! If anything she might send you a thank you letter!!! Lol!!! The red paint just doesn't look as good in pics, it turned out well for me. And I'm going to try to add some detail to interior, that's why the dash and wheel. I want to keep them dark so not seen but still there if you look. If I can discipline myself she might be a candidate for build of month, just not sure what month, or year,,lol!! But the building of the old bed and hydraulic hoist wasn't a complete failure, I did learn some things along way. Like its good to save money by doing something yourself because you will need that money when you realize you aren't doing well and need to pay someone else!!!!

[Cooper]

Oh and the other pieces in the pic are the light buckets and hardware for the d11 lights. :)

[Lil Giants]

Yeah, Reg makes some beautiful boxes & his screwdrive is the smoothest & powerful in the market today, you made a good buy. ;)

Your dozer don't look to be too bad for wear, care to take a guess how many cubes it pushed this yr? :D

[Cooper]

Humm, I will have to think a bit, five skidsteer buckets, two back hoe buckets, then the countless hours moving the same material around in the backyard pit. I would be guessing that I've got at least 40-50 hours on it. But my wife said I was crazy, I have a lot more than that. She said I had about four hours a week on it on average, 30 weeks that's about 120 hours. Man time flies by when you are havin fun. !!!!! She may be a lot more accurate than I had originally thought, quite a bit of time pushin dirt at our Riverlot during the weekends too.

[Cooper]

Bent blade lift eyebolt. As you can see it wasn't threaded all the way because I didn't pay as close attention to keeping blade square when I made it and unthreaded it to get closer to level.

I'm going to remake the link between track carriers and frame. I made it with allowance for left and right side to flex a bit like the 1:1. But to me I think it is unneeded and just allows too much play for tractor.

And don't throw away that old recliner!! It's my swivel for painting and working on things!! Simple , big, and easy to stow when not using!!

Just cutting for threads on a new filter, I stuff holes with ear plug material so nothing gets inside.

And insides of old filter. A couple particles but pretty good.

Made up the new piece connecting track carriers to frame. Has very little torsion movement.

And after thinking about making all new track pins (and inspecting them) I decided to just keep them until failure. For 90% of them it looks as if the brass has worn and not the links. New pins will be make of stainless or steel. In the pics you can see the two wheel carrier pivot pins. I made a new location, down 1/8" and back 1/4". This will get the track more flat to surface and more force to front. When originally made I had the front and rear wheels slightly higher than middle, not intentionally, just a miscalculation. This new pin location also takes most of the play out of the stretched track and reapplies original tensioning locations. I don't know if you can see the track laying flat and up front it curves up some (front wheel is little higher-that's what new pin location in back solves)

Yes I know the buckets are big, they are hiding 10mm LEDs. I have a lot (80+\-) of them. (Impulse purchase from a while back and need to use them). Now I need to wait for some resistors to show up in mail-couple days I think. )

And I am like a kid, rushed home over lunch to see if mailman had stopped yet, nope, not yet:(. Have some black shiny box thing for the truck build!!!) well back to work for a while, looking forward to end of day and seeing a big cardboard box on doorstep :).

[Supermario]

As much as I hate to see the dozer all apart, thanks for sharing a closer look at the beauty. :cool:
Besides, this is normal wear and maintenance not a case of use and abuse :eek::lol:
Sure brings back memories for me seeing it tore apart. I've personally rebuilt 4 D10 dozers and countless D8's over the years. Enjoyed it all. BTW , The link that connects the track frames to the machine is refered to as a " hard bar".
I made the same mistake when I installed new motors on my plastic dozer. Put them to high and now the dozer rocks from front to back when you blade down and causes even more fun when you want to blade up and it takes forever to react until it rocks forward:eek::mad: . Will fix this winter for sure.

Anyway, great machine and build Ralph. I can see how much time and effort you must have put into her. I see lots of tiny threaded holes in the close ups:eek::D

Mario, here at Great Dane construction co., we are an equal opportunity employer. You don't need an education as we are more than willing to educate our employees in the way we want. It doesn't take a monkey to wrench on our machines, here is one of our employees now working on hooking up lights and some minor other work,

Now you don't need to be a rock scientist and we don't pay more than peanuts but our employees are well taken care of.

My hands are way too big for those little nuts and bolts so I've outsourced most of the work to the locals. They have a better grasp on those hard to handle nuts. But it is hard getting good help, as soon as the five o'clock bell rings they get all squirrelly and want to go home!!!

(Just couldn't help it! I know :))

Yea I'm still on the learning curve and keeping track of what to improve on for a future dozer. The front and back wheels ended up being slightly higher than the rollers. Like you said it would enable the dozer to rock a bit. I did also try and lower the attitude of the front of machine to give a bit more traction to compensate for that with different locations of pins going through the hard bar :) and now having the back wheels lowered will help more (I hope). Man I would have loved to been beside you when tearing into a d10!! Thanks, it's been a low problem machine so far and like you said just some normal wear. I finally did something right:jaw:

[Supermario]

Lol. I wonder if I can train the black squirrels in my yard to do that.:rolleyes: I think my wife might have an issue with a squirrel in the basement though:eek::lol:

always nice to mix a little nature and wildlife into our metal and electronics hobby I say! :D

Pictures just don't do these justice!! Thank you reg, RCP!! You are making an excellent product!! I'm almost glad I failed miserably on my attempt on the dump hoist!! Once I get the d11 back running I'm devoting my time back to the dump build. A couple days, I'm waiting on a couple resistors for the lights.

Also showed up were some drivetrain components from rcbrim, axles and the tranny. I got the 2 speed 1:64 or whatever the lower version was.

Got some more goodies today, the 1w resistors needed to finish d11lights. A couple punisher driveshafts for the dump trk, and it found these slider center detent pots. I'm thinking of installing them on my radio for the excavator, replacing dial pots and relocating them for finger friendly. http://i1357.photobucket.com/albums/q750/cooperford/E0A99CB6-F27C-4ADB-9F88-BE1C29C9383D_zpsmx6qzkom.jpg

And I'm not sure about this but I picked it up a wallyworld. It's a series of push button switches. I'm thinking of tying this into the battle switch to be turned on / off via radio. Then I could manually have on or off whatever I wanted, like fan, front lights, back lights, sound ect.

And I finally have the rest of tonight to try and get d11 done so I can start working on that awesome dump box I got from reg!!! ****, I've been thinking of installing a plastic liner because it looks so good and I don't want to scratch it!! Damm something of mine that doesn't have scratches!! It just wouldn't fit in :).

[RCP57]

Hurry up would ya!:bounce::bounce: I wanna see scratches in that bed ASAP!:cop:

Lol!! Had to take a break, my eyes are starting to bleed , my hands shaking , my brain is overheating!! All these little wires and keep grabbing the darn wrong end of the soldering iron!!!!!

After doing all three and getting sidetracked a few times, installed only to realize I didn't check the inside screws that was the main reason for taking them apart!!

I am completely ecstatic and extremely thankful to have reg get me a dump body. We didn't realize the Aeromax frame is one inch shorter than a kh. Had some mock up and tear down several times and finally ended up moving the rear forward one inch. After,

Got a nice driveshaft and tires that are just a tad taller than stock but still the front end is sitting up too high, going to have to make new leaf springs, probably several straight layered style. And got rc4wd parts today, tires, the drive shaft and adapter for front wheels to drive axle. Now it's not rc4wd fault as it says in product description (one piece) but I did not read and assumed the hex adapters would be a set of two-nope one. So another order:). When I ordered last, I had realized I forgot something (a longer driveshaft) I made a second order within five min and in the area for comment I asked if they would stuff second order in same box and save me the $40 shipping charge. If they could great if not it's my own fault. But $40 shipping a driveshaft? Wow, oh well. Got the package and it was only one, but shipping email had two tracking numbers. I'm thinking great, dhl lost or forgot the second package. Nope the drive shaft was in same box, but I still am getting nailed for $40. I usually don't complain much but damm if I'm going to pay double for shipping then darn it ship it seperate!! Or credit my cc. Maybe it's just me as last couple days not much has been going well, truck wouldn't start, diesel, cat poop in Landry room - found it on the underside of my shoe on the way out, fridge frozen, have to spend xx on four new sneakers on the truck, ect,,,,, and I've become rather verse in tearing apart whatever I just put together!! Lol!!

But it's the fun of scratch build right? I guess part of it is I just can't wait to haul some dirt,, I even have been thinking of some sort of liner so I don't scratch that awesome box reg built!!

[RCP57]

Despite all of the headache, your truck is really looking good and will be a real workhorse when finished! The color red you chose for the cab and the velvet black box look really good together too! It will be done before you know it and then you will have to start on something else....It's a vicious circle...

[TRUCKMAKER]

Sounds like you need an excavator with a sifting bucket to clean out the litter box. Trucks looking good, looking forward to some video!

If you want to make U bolts I take stainless rod thread one end bend down and across then measure for the length of the other side and tread the other end then bend it. I have even flattened the part that goes across the spring before bending the last leg of the U bolt. Ed

[Cooper]

Had some time to get back on track!! Just a pic of the driveshaft. It's plenty beefy!!

And figured out the locker servo. I am using a high torque mini servo for all axles. I was able to lay it Inbetwene frame rails without any interference or being seen. I didn't want to hide that big driveshaft.

And the front, still have a bit of figuring out to do for electronics and placement. Probably going with same style I used on the other aeromax.

[thebigo]

Very nice work you got going Cooper. Really like your partners working with you, speaking of your Dog and squirrel. My Boarder Collie is to much of a wimp to be around me, cause i am usually firing up the tools and grinder, it scare's him

[thebigo]

Did you make your own cable holder and I see you have some other CNC made parts on the truck as well?

[Cooper]

I've kept the door closed to the garage, cats only. The dog, Great Dane still a bit of puppy loves to raid my tire box and the foam inserts!! He is really bad at taking small parts when your not looking only to find them in the bed at night!!! The cats usually sleep on something or in something. They just flick an ear when air compressor kicks on and maybe lift a head when I hit the chop saw,,that's really loud!! But other than that they just are happy that the dog isn't using them as a living squeaky toy!!!

Yes, bingo, I made the holder for the servo and cable stays. 2-56 set screws holding the cable housing in place. I'm going to go and mill out/away any unneeded material to lighten it up as much as possible. And it's all manual milling no cnc,, my redneck cnc = crank, number, and crank again!!! I do have a digital read out for the mill and that was the best thing ever for me. I've been thinking of going cnc but I would still need the manual mill. Have been looking at setup thank still have the crank handles to allow manual milling abilities. The hard part for me is the computer stuff:).

Well it's confirmed it's a kitty (better word but keeping p.g.) magnet !! Glad I got a few of you to chuckle. :).

Ugg one of those days again!! Rain today so some playtime or work from home as I tell the wife. Designed some fuel tanks and was going to change filiment from white to black in the printer. Pretty easy to do but,,, the roll of black I have is bigger and I have to print or make a holder for it. And my enclosure is going to be too skinny for that little wider spool!! Ugg another project I guess. For now I'm going to print in white as I'm sure some tweaking will be needed.

[Cooper]

And thebigo sorry about bingo, darn spell check!!

[Cooper]

Made some square fuel tanks up, have some tweaking to do but general idea.

Still have lots to do on dumptruck, flaps, tanks, might mess with fitting bumper better. I keep telling myself it's a 4x4 conversion and body is higher cuz of that :). Hitch for back, lights, ect. It's never really done :).

[TRUCKMAKER]

Cooper the dump truck is looking good. Check out Hanks truck pictures/ Robert archer collection and look at the page on dump trucks it has a bunch of Ford/Sterling pictures, it might give you an idea of the bumper style they used on their dump trucks. That 3D printer will come in handy!

[Cooper]

Will do thanks, I've been thinking of the bumper, will have to learn how to split for printer bed isn't as wide. I think it will be easy, the hard part will be the finish, I like Crome bumper but that ain't happening with printer. But parts can be sanded and filled to look flawless. Just now getting the finishing down with my home meth lab,, lol,, cooking acetone in an old crockpot. My wife was wondering why I was doing that and I told her to go watch breaking bad ! (TV show on meth stuff). Just for those that don't know, a vapor bath in acetone will flatten much of the imperfections from 3d printing.

Didn't somebody cover a bumper with "chrome tape" a while back?
Cheers, Neil.

[Cooper]

I know just what duct tape you are talking about, foil tape, I have lots in the work truck :).

Just a short video of truck speed in low gear and high gear. At first I was thinking way too slow but for what I'm using it for I think it will be just the right combination between first and second gears. And got the big kitty back together with lights. (Just in time for the ground to be frozen:(. )

http://youtu.be/NnE1AoXVTJI

[Lil Giants]

Trk spd looks about right. It looks like it doesn't turn that sharp though. :thinking:

Are your lights hooked in series or parallel? Could you rig up the rear lights on a separate switch or just activate in reverse? cause they look bright enough that they may impair your view while travelling forward.

Your radio not have model match? You have to turn one model off before turning on another?

[Cooper]

Speed- check,, like I said when I first ran it I was like darn way too slow but realized hauling dirt on dirt road, speed should be perfect for me.

The lights are in pairs, front, top, and back. I can turn on/off any of them as long as those pairs. Example, front 4 lights on one circuit, left two are series wired then parallel with right to a switch board that can be turned on/off manually for each circuit (6 all together) with that being controlled by radio switch. So whatever switches I have on I can control by radio. And fan on one also.

Model match,, keep forgetting to try that. I'm not sure about the sabertooth and radio rx I have. I may have to program fail safes to keep it from drifting.

And the steering, the tires will contact leaf springs. The axle will turn more than twice that. I may look into what others have done. They are stock tamiya springs with rcbirm axles. I am using super wide tires in front. Will play around with that in mind.

Lol,, yup mx'er at heart. Back in 2001 I went pro, before first race I had 60 staples in my knee:(. It was a year before I could get back to practicing and then two more surgeries, another 6 months, and yet another, about 4 months,,,, by that time I decided to level all my practice tracks and bought a street bike. Kinda what got me into rc stuff,, can't get hurt right?? Well not as bad and definitely not as risky. As the saying goes the old man is wise and wisdom comes with age!!-- I got old too!! Friends always try to get me back riding but I know once I do it's gonna be expensive again. Guess the wisdom thing works:lol:

Got one side tank done , one more to go.

[thebigo]

Ya, I do a little of everything, I have a mx track on my place, just started trials couple of years back and really like that, also like to do enduros and hare scrambles. Use to race Stdium R/C truck's way back in the late 80's. Guess you could call me the jack of all trade's master of none. Now just learning from you guy's on the trucks and equipment, and just love it. I do still love riding, but I can tell my reflexes are slower from age, so can't school the youngsters that much anymore.

[RCP57]

You guy's need to stop talking about dirt bikes! I'm getting the urge lately to buy a new bike even though I haven't ridden much in the last three or four years(where has all my time gone?Hmm?)....Hearing others talk about it is not helping. I even groomed my MX track a couple of weeks back but then the weather turned cold and the ground froze before I could ride. The weather is warming up so I guess I will have no excuse not to put some laps in on my oldy! Too bad I'm so outta shape and fat.lol At 9K for a new bike I think my business needs to pick up before I rush out and buy a new bike!haha

Got the ubolts done. I just settled on m3 threaded rod and a piece of steel brazed then ground round.

This is how I did the tanks and strap, used ss for the strapping.

[Cooper]

And in the spirit of Great Dane construction company business I'm going to tear into the 4200 ex despite being done with other projects. We here at GDC, never really finish anything and are always eager to start something new :) before finishing anything old. :).

On the docket for the 4200;
New cylinders
New rx/tx system
Update track drives
Scale cab and body more towards 1:14
Bucket possibly with quick connect.
More lights
Not sure if it's going to be a hitachi or cat, I'm partial to cat but it suits a hitachi better (I think)

Just let the dogs out and some of the loose dirt is workable, I may have to load a few loads with the excavator into the new dumptruck before dismantling. I have noticed to be careful with hydraulics in -0 weather. It's probably just not a good idea -is it? I may have to get them pretty warm before taking a video. :)

[thebigo]

Coop, are you going to use the RC4WD upgrade track drive's? Why are you changing out cylinders, are they just worn out? By the way the truck is looking awesome.

David

[Cooper]

http://i1357.photobucket.com/albums/q750/cooperford/660BB68E-417C-40EF-B354-F44E94EB1564_zpsxmpvhfcu.jpg

That's one reason for changing out cylinders, look at my dozer from summer, and I changed/added oil several times. But I want to make better cylinders and hard lines. Kind of like the six million dollar man show, we have no reason to do so but we have the ability and technology to do so :).
http://i1357.photobucket.com/albums/q750/cooperford/534C9EDB-6872-46BB-81D4-65397CB31C06_zpsc0d9scho.jpg

I've been thinking of going the hitachi way but I am a cat man at heart. For scale in the 1:14 range , keeping with the trucks, what do you guys think would be better suited? A 345d or a 374L? I'm leaning towards the 374 as I can build up the back some to make appearance of the bigger machine. As far as cab goes I may cut down or print new parts.

And thebigo, I do have the track upgrade motors, I tried them before and had some voltage problems. But this time around I'm using different esc and better radio that I can tweak how I want. The esc I'm using has a drag brake. I've noticed with this model that in heavy digging force you can roll the machine forward. I really hate that. I would rather have force to skid it than have the tracks roll. And with making new cylinders I'm upping working pressure. Ah, another question for you guys, I was planing on keeping the original pump/motor. I have the premacon pump it the dozer and it is flawless so far. By going off specs the rc4wd pump can deliver higher pressure but what is reality? I'm wanting to limit it to 25 bar- 300-350 psi. (If everything can handle that, I think I was running around 20

[Lil Giants]

The Premacon hyd kit has a Jung pump capable of 100bar. The pump motor is properly gear reduced so the brushless motor & pump run at correct speeds & the esc won't be maxed out in Amps or heat. And the Meinhart rotary valves are just far superior in smooth oil flow.

I think this model's overall size is moreso a 345 series.

Does the track motor upgrade have planetary reduction? I don't think spur gear will hold even with a drag brake in the esc.

What bore size cyls were you thinking of making?

[Cooper]

Hey joe, yes the drives are planetary gears, so some movement might happen but minimal (I think). I just hate when the machine rolls forward!! I like how I have the dozer set up to run pump at 30% until stick imput ramps up to 100%. I don't know what's better, that or having pump %100 with bypass like the excavator is set up with a 4th valve. I never timed it but using the same battery I know I can usually get close to an hour on the dozer and in the excavator I doesn't last as long. I would have thought different with dozer running two motors and pump vs one big pump on ex. I think the drive motors in dozer are pretty mild and the big motor in the excavator is amp hungry. Running 8400mah 3s battery.

The cylinder tube I use is 1/2 I'd and 3/4 od. I can easily lathe down od to suit whatever. Also the 1/8 wall allows me to drill bolt holes into cylinder without soldering another piece. Cylinder rod will be 5/16? I forget exact size something along that. Are those meinhart valves the premacon ones? If so that's what I have in dozer and have had no leaks, problems whatsoever.

I know some may wonder why I'm transforming a decent working machine this rout but my intentions when purchased in beginning of year were to use it as a template to make one or to revamp using most parts to make a heartier beefier momma earth cutter :).

http://i1357.photobucket.com/albums/q750/cooperford/3e7f63b05f46aef3ba554cc3cb7df734_zps20d7aa57.jpg

Just an estimate if I can run 400 psi. I have hose rated to 350 and have been using it with no heat breaks or leaks. That's what it's rated for so I'm sure it can handle a bit more :)

[Cooper]

http://i1357.photobucket.com/albums/q750/cooperford/363EE130-D278-404C-AF1E-FE54107828E1_zps1dcrl8ct.jpg

This is the cylinder I had made for the dump project, just to show size,

http://i1357.photobucket.com/albums/q750/cooperford/F8495845-9C02-49F9-8507-2410CC4ADC99_zpsejsuedn9.jpg

One of the 4200 cylinder side by side. Same .75 od with same .315 rod. (Standardmetric ruler :)). 4200 has id of .635, that equates to more hydraulic pressure but I think 80 pounds will be plenty with the .5 id of the brass rod I have. I purchase the rod already. I tried to drill/lathe out but it's me or my machine, I can't get precise results on the longer cylinders.

[RCP57]

Sweet! I think the air line that I use is rated for 300psi and the burst strength is 1200psi. I run around 435psi in my excavator and have never had a hose blow.

[thebigo]

Very nice Coop, I think you made the right decision. These excavators , in my opinion, are kinda nice the way they come stock, but the scale of the cab is really off. Really think you are doing it the right way and I need to remember this thread when I go about my transformation on my 4200 some day.

Oh, I like that you are making it a Cat, Joe Idea is good for the 345 series.

David

[Cooper]

Ok it's done 345 it will be :). Or close to resembling one , logo and number :).

Last night I got most of the wiring done. I put bullet connectors on most everything. I hope to make enough room that I can have those two 3s batteries in there, more weight at back and 10amps to play for a while. I wish I could find a controller like saber tooth for brushless motors. I could then mod the radio with an xbox joystick for track drives.

[Cooper]

Had some time before it got dark to formally test the dumptruck.

http://youtu.be/ZVABVUYxeqQ

And did a little off roading, it had rained early in morning so dirt was wet but not muddy. The camera doesn't really show but it was a pretty decent incline for her to walk up. And then just had to use the front bumper for a plow in the piles:)

[Supermario]

Love the dump truck Coop. looks like a great job site workhorse for all seasons.:D

I also wondered what Cat model to repaint my 4200. Based on undercarriage width of 10" that does suit a 345. Adding to the upper structure will definitely add to the 345 look.

For me, I'm going with a 330B. I've worked on so many of them years ago, only seems appropriate I have one at home to work on again. :D :lol:

[Cooper]

And just an idea of undercarriage speed. I have it set to 45% and brakes too.

Thanks Mario, I never get to run the big stuff, usually mini exes and skidsteer. I think if I can get the cab scaled down and a bigger exhaust cover that will help the scale look. Like I said before if I mess it all up the logos and numbers will be good enough for scale :). Lol!! I would love to put better hydraulic pump and valves in but cost is making me think. Oh maybe Santa can read this :lol:

[Lil Giants]

The undercarriage would be a great deal of work to reproduced in steel, but seeings how you're re-doing the house anyway, why not do it all from scratch with plate steel to get your weight up? No point going big power on hydraulics if it aint gonna stay planted.

You could mill down each center grouser bar of each pad a few mm so it grabs the ground better too.

[Cooper]

I'll look I to that joe, more weight would be good. And if it's possible to mill the middle groused out and keep tracks together I may do that. There should be more spacing between shoes also. Wouldn't bind as much. I just don't want to have to remove and install all those roll pins :(.

Between shoveling and plowing I got a good window seat today:)
