Andy, you have an amazing fleet of great equipment ! :cool:
Welcome and glad you could join the group :)
I really like what you did with the 4200 upgrades. It looks spectacular. Nice work:cool:

cheers Mario, a bit of paint and a cheap plastic excavator cab and some old panel vents I rescued from the scrap bin, also made a few decals and it looks way better than standard.

hope the youtube link works, first test run of screener, had to get a new vibrator motor recently as the old one spun in its mounting and destroyed the connection tags , so chucked some brass into lathe and made nice counterweight as well, works a treat now.

time to go to work , will post more picts tomorrow.

heres a quick video of the 4200 making a new road up to the trommel

please excuse the learner driver in the loader . he needs a lot more practice.

have used about 10 batteries in loader and it runs like a dream, have also checked diffs for play and wear inside and all is good.
hopefully its only an issue with a few of them .
have been dealing with a guy named Tang at eagle machinery in China over missing front wheel fenders and a few bits and pieces I would like to get for the excavator, cant say enough about their service !
I will be getting all of my rc gear direct from them , TOP GUY and an arsom price.

Never had a rc with sound before but now im hooked.

loader driver has a long way to go before hes qualified much better in the excavator.
Guess I better change the battery again.

got a bit of painting done, want to paint all the light holders and still waiting for front guards to turn up, also have a slight problem with the loader.
one of the rear wheels has come loose and my small nut driver has gone missing so I cant sort out my loose wheel.
I don't want to go to the local hobby shop just yet, It could end up costing a lot.( usually dose , all those shiney things)
cheers for now.
going to redo the decals on the arm as not correct and also theres a few to go on the motor housing .

ps the loader is only allowed inside if it sits on the newspaper LOL.

all right time for some updates.

excavator:
ordered a sound card from eagle machinery ( same as my loader)
and crammed it into the excavator, am running it of the 4th valve so after my Y cable (signal reversing) turns up it should be all go.http://i1322.photobucket.com/albums/u575/andyathome/20140918_120331_zps2c51085b.jpg (http://s1322.photobucket.com/user/andyathome/media/20140918_120331_zps2c51085b.jpg.html)

have also made a few decals for the rock truck, http://i1322.photobucket.com/albums/u575/andyathome/20140912_104425_zps854c2836.jpg (http://s1322.photobucket.com/user/andyathome/media/20140912_104425_zps854c2836.jpg.html)

also had a slight problem with the loader.
had a rear wheel come loose from the axial, emailed tang at eagle machinery and got a detailed how to do , remove wheel, remove ring gear, pull axial, pull washer , look inside and find 4 small bolts holding planetary gear to axial housing tighten up and all good.http://i1322.photobucket.com/albums/u575/andyathome/20140916_212400_zpseef4cbf1.jpg (http://s1322.photobucket.com/user/andyathome/media/20140916_212400_zpseef4cbf1.jpg.html)

new drive motors for excavator have turned up so will fit those when I have a bit of time, also front fenders for loader here and painted.http://i1322.photobucket.com/albums/u575/andyathome/20140917_112724_zps51834bb4.jpg (http://s1322.photobucket.com/user/andyathome/media/20140917_112724_zps51834bb4.jpg.html)

also have eight more diggers, early one morning on my way to the shed for a bit of play time and I spot this. http://i1322.photobucket.com/albums/u575/andyathome/20140918_115056_zps306eb21e.jpg (http://s1322.photobucket.com/user/andyathome/media/20140918_115056_zps306eb21e.jpg.html)

heres a real quick video of the sound card, flat battery.
you can see how the revs drop when the sticks are moved, the signal reversing lead will fix this.

cheers andy:bounce:

andyathome

09-19-2014, 01:49 AM

heres a better video showing the issues I have .
sound card wont shut down, because Im using the 4th bypass when there is no stick movement the revs are high.
in order to shut down the sound card I have to stop pump, use a stick , drop sound card revs then use a track and all shuts down.
when the reversing lead shows up all these steps will be gone, hopefully:D

Have just finnished installing the new track drive motors.
Found out why the tracks were jumping, I have sheared both pins; probaly due to driving small gravel and ignoring the bad sounds .
I didnt have 2mm by 35mm pins lying around .
measured a few pop rivets and they are a perfect fit.
1 battery flat , new motors work sweet and the pins are still going strong.

10-03-2014, 07:16 PM

ok, finally bit the bullet and got another lowboy for the fleet.
was a stock standard rc4wd lowboy but it needed some upgrades.
all the fleet trailers are red so ,out with the spray can.
also cut up some 5mm MDF sheet and used a slitter blade in the grinder to make some fake planks.

cheers paul,
waiting for better weather then a few more outside shots.
got the conveyors finished and running good.
need to put loader back together, had a bearing failure in the rear diff.
input shaft bearing toast!
got a new gear set from manufacture (free) and put some shims in around main diff gear bearing, and milled a bit of clearance for the diff lock leaver ,also rechecked front diff and fitted shims, milled a bit out the same as rear diff.
need to find a bit of time for a play to see if it is all good.

10-04-2014, 03:18 PM

Thanks. Had to get a few while it was still all shiney..
now I need to try several batterys in the loader to see if my fix is going to be long term.
I can see why the bearing failed, just really bad clearance in the castings and a lot of loading.
I see this all the time at work on the cheaper electric motors that are fitted to some of the machines that get installed buy the bean counters.
they wonder why maintenance cost is so hi.
need I say more.
dose any one know if theze are the same axial setup as the armagedon dump trucks and do thay have the same issues.

Great Equipment you have there!! I am just starting, so far i have the excavator like yours and the armageddon dump and my Loader like yours is on it's way. Think I will pull it apart and do the diff's right away. Is that Big dump truck manufactured by you or another outfit?

andyathome

10-13-2014, 11:46 PM

thanks, takes a while to get a fleet together.
and yes pull the axels and fit shims, also make sure all the bearings are there, mine had the bearings in the axel tube missing, standard tamyia bearing will do the job.
the dump truck , if your talking about the yellow rock truck, I scratch built it from scrap metal I rescued from the rubbish bin, I think there is a post on here under MY JUNK ROCK BUILD, has a hydraulic tipper and electric steering.
need to get some small rams, or make some when time allows for the steering.

heres a quick video of a bit of axel bashing on the loader, still going strong, must be 20 plus batteries and still no problems, cant say the same for the speaker connections, must be shorting on diff lock steel cable.
will fix on next days off.

I borrowed a few small bits from work, brass shims 1.5 mm thick and super glued two pieces top and bottom in the main diff gear bearing housings , makes a nice sung fit, no way the bearings are going to move around now.
I measured the bearings and then the housing and found about 2.5mm of difference!
not exactly a precision casting, but all good now.

Now that's a nice wall of fun!!! I had the wife convinced (and myself) that you had the sandbox inside the house. From other posts you could see a couch and looked to be inside. She lets me run them in the house but don't think I could bring dirt in the garage. Although the supports the idea of me building a vacuum truck.

andyathome

10-14-2014, 12:00 PM

Now a vacuam truck could come in handy.
As for playing inside. Punishable by death or so ive been told.
we bought a new house about a year ago. Wife got itchy feet I said big shed and that was my main want.
a week later she found a house with 4 acres of land and huge 4 bay shed .
go to the auction and we are the only bidders.
next minute we are moving.
I will suggest tha vacuam truck idea to help out with the house work. If you dont hear from me again you will know what happened.

10-14-2014, 02:21 PM

also need to point out that there is another use for the shed,
you cant just play with RC consturction modles all day, belive me Ive tried.
sometimes you need to make things. was lucky enough to get these two toys at a really good price, next to them is my paint box. have fitted a small fan heater at the bottom and cut a slot at top of box to let the heat out. makes painting all year round possible. welders and grinders on other side of shed so lathe and mill dont get covered in unwanted dust.
I plan one day to convert the mill into a CNC set up as ive seen it done on the net , looks easy enough but a little costly at the moment.

Thanks. Yeh a mig will work. Turn if way down.
personaly I used my mig on the thin stuff , just makes for a lot less cleaning up after welding.
The only thin part on the truck is the tipper so if you ask an engineering firm to weld it up for you it shouldnt cost too much.
the cab is made of rubbish plastic , super glue and a lot of filler.

after numerious requests for how the excavator has been wired for sound.
this is the sound modual I got from eagle machienery of aliexpress, the connections arent how I ended up running it in the excavator, I also fitted a signal reversing lead on the 4th valve so revs picked up when the sticks were moved. I will take a few photos on my days off to show which channels i used on the reciver

how I installed my eagle mach sound card.

photo 1 ;
channel 6 track motor use a y connector and put track motor cable and the orange lead to sound card.

photo 2;
channel 7 4th valve .put signal reversing connector into channel 7, put white lead for sound card into one of the output leads and 4th valve into the other.

http://i1322.photobucket.com/albums/u575/andyathome/20141015_184908_zps680ab9b3.jpg (http://s1322.photobucket.com/user/andyathome/media/20141015_184908_zps680ab9b3.jpg.html)

at the front of the excavator there is a strip connector to supply the esc,s . I connected the power cables for the sound card into one these.

mine didn't work how I wanted ( when stick moved the revs decreased) on the signal reversing lead there is a small pot ( photo 3) adjust left or right to change out put signal, once done the revs will increase with stick movement.

http://i1322.photobucket.com/albums/u575/andyathome/20141015_184908_zps680ab9b3.jpg (http://s1322.photobucket.com/user/andyathome/media/20141015_184908_zps680ab9b3.jpg.html)

I don't know ( haven't tried) if it matters which lead you use that comes out of signal reverser . but I do know if the signal is reversed to the 4th valve when you try to start the pump it will stall( not good swap wires around or try adjusting the pot 180 degrees)
a bit of guess work and it works perfect.

last picture job done.

cheers Mario, an 8400 battery holly cow it must be huge , how long is the run time on it.
im getting about an hour on the 6500 that came with the excavator.

just a quick up date on the loader, diffs are working great , have been thrashing them by pushing and digging way to bigger loads and also trying to push the dirt box in high and low gears . the wheels just spin and loose traction , no bad noise from either diff, pulled rear diff and inspected yesterday ( all good) , only did this because my rear drive shaft fell out. this wasn't a problem with the model it was a problem with the twit that put it back together last time and didn't do up BOTH grub screws!!! it would appear I only did up one of them.
I think I need someone to check my work LOL.
having read a few posts about the loader issues I can see why some people are angry , but having said that now that mine is sorted I am more than happy with it.
enough talk im off to the shed for some play time.
will post a video today of the new pit and some loader bashing, after I do the lights in the mrs shed , and a few other jobs she wants done.
how is it on my days off ive got more jobs to do than I have to do at work?

forgot how slow the blade rams were so they will be swapped for faster ones.
will make a whole new base and install tensioners for the tracks, also will nut and bolt track pads as pop rivets don't last.
will also fit 2 more rams so I can tilt the blade, then a paint job.

ok, so the king hauler finally has a reduction box, 4:1 fitted.
problem was when hauling a heavy load I had no steering, it was suggested that I make a dolly trailer, had a spare flat deck doing nothing .
end result after 40 minutes is an average looking dolly, but I have steering.
will clean it up and paint, I can now haul the excavator and loader no worries.

sorry about the photo , its late and dark here.

10-28-2014, 06:31 AM

Andy,

A couple of suggestions...
- move the fifth wheel further forward, possibly just before the middle axle.... It will require a long neck on the trailer or dolly, but will ensure more weight is over the front axle.
- on the dolly, make sure you are transferring some weight to the truck, otherwise traction will be a problem..

Finally is the reduction box behind the main box, or between the motor and the gearbox?

Cheers,
Ap

finished the dolly and had a test drive, have mounted a box above hitch so if I need to I can add some weights to get extra traction, will swap tamyia tyres for my off road ( and softer ) tyres once I make some foam inserts.

as it is with the dozer on the lowboy it tries to lift the front wheels , so will be interesting with some good tyres.

Hey Andy, is that skid steer in the little hill in the background a Bruder? Is it a good functioning Model? I also wanted to get your opinion as well as other's , I see you have a 4 axle truck pulling your Lowboy, very cool. I Have a 8x8 MAN Trackter dump, the one they sell on RC4WD, was wondering, how do you think it would work if I used a Dolly and the same trailer as yours behind it?

andyathome

10-30-2014, 10:04 PM

hi, yes its a bruder skidsteer , but as yet unconverted. one day.
as for the truck you will need weight on truck to tow a good weight, are you talking about removing the tipper and fitting a 5th wheel.
I have a tow hitch at rear of the semi , I have a bruber dolly so I put that in the hitch, and attacted my dolly and trailer combo with dozer on trailer just to see what happened..... nothing really lots of wheel spin. so what everyone has told me is you need weight over 5th wheel to get traction is 100% correct.
8x8 I think it should work, but to be sure post in the big rig section .there are guys who will know for sure.

hi david, theres only one way to find out if it will be too heavy.
My truck pulls ok but standard tamyia tyres are only tempoary , I have a full set of off road tyres to fit just need some foams as they are too soft with all the weight and side walls colapse.
you could load up truck with dirt , that will give you better pulling traction.

a quick update.
the dozer has been stripped and I have made tensioners for the tracks.
just a tube inside the track body with some heavy springs, seems to work nicely.
made up some brass wheels and these need bearings fitted, but for testing a bolt will work short term.
also widened the the track body by 30mm for some extra clearance form the body to avoid rocks getting jammed between tracks and pannel work.
also modified the blade and made some new arms for the blade.
next i will redo the tracks with some new pads.
then it will all be stripped again and sand blasted and a new paint job.
later on I will replace the rams with faster acting ones.
its 4:50 in the morning so that will do for now.

had a bit of spare time tonight so,
all wheels fitted with bearings, made a bit of a stuff up and predrilled wheels and body and used 8mm bolts to hold it all together, the bearings im useing are 5mm centers, problem sloved by tigging some pannel washers to body.
also cheated a little and fitted teflon runners for tracks , and added a cutting edge to the blade.
Im going to redo the ripper set up as I think it looks rubbish.
got a fear bit of clean up to do with the dremmel and a bit of sanding but its getting there.

any way picts of tonights efforts.

weather was pretty average today so I made an executive decision and painted the dozer, here's a couple of pictures showing the travel of the ripper.
I will be making a new blade set up and going with a large single ripper in stead of the three blade set up.
I have run out of paint so off to get some more made up, will pick up some more aluminium and do some new track pads, they will be 15mm wider than the original ones, so traction wont be an issue, these will be nut and bolt , no more pop rivets.

I love the paint box, I built a drying /oven a while ago to speed up drying time and now that the paint is dry I can continue the build.

not sure on the black blade? also going to cut it so that it can be moved with two more rams.

the wife picked up a new driver for the dozer, not sure he gets on well with bob the truck driver .
as for the dirt bike I sold my Yamaha TRX 850 a while ago, too many speeding tickets , but I replaced it with a Yamaha WR 450 so technically I can ride a dirt bike most days, usually on one wheel on the way to work .
back to building.

its been a few years now since CAT changed the color scheme on dozers and skidders.
Nightshift operators complained of glare from the hood and blade on dozers. That's when Cat started painting the top of hood and backside of blade black.Same with skidders, top of hood black and the grapple boom and arch black to minimize glare.
No need to worry with RC's about glare and no matter what you choose it will be right and look great. Nice work :cool:

Nice Andy,

that Dozer can push rock with ease!! It must have some good weight to it.

modelman

12-08-2014, 02:03 PM

Andyathome-I wish you would think about something before you change the blade lift speed. I think the speed is good. A lot of dozers you see on here are jerking the blade up & down 1/4" and that is not realistic. You will never see a full size dozer with that extreme blade movement. When I watch a video of a model I like to see good, steady realistic movements of the entire machine and I think your dozer does that. All the video of real machines that I have watched the blade movement is so slight that you can hardly see it move while they are pushing. You can not do that with fast movements of the blade on a model. Your scale look is off a little with the very high sprocket (was there a reason for this), but I will take a model that works good over a model that looks good anytime and yours certainly seems to work great. Your model looks good, I was just talking from a scale point of view. It pushes the rock & gravel with very little effort and it will be interesting to see it in the dirt. Nice work, keep at it.

andyathome

12-08-2014, 07:34 PM

hi modelman,
unless santa brings me some more rams ( not likely) I will be keeping the slow ones.
after a bit of practice we are getting used to them and when to activate them to achieve what we want the dozer to do, I weighs in just under 35kg with a 6500ma lipo battery and has a few issues in the pit, If we push too much dirt it digs a hole with the tracks, so soft dirt will be a challenge.
just need to change our driving style, or wider tracks.
as for the track sprocket height, with the type of motor gear box I have that is as low as I can get the drive sprocket, just a space issue inside the dozer, I could have made it longer and wider to get the right look, but then its not going to fit on the trucks and will be way too big.
for the time being the kids are enjoying them selves and it pushes good.
I still have about 8 feet of track leftover so might build one for me and try to do it more scale, once I finish of all other rc projects and anything else the wife comes up with .
at the moment this is still a hobby and hasn't become an obsession yet but I can see it happening. LOL..

had a bit of time to replace the ripper.
found some good sized bits of aluminium in the junk pile and come up with this, in picture it is fully extended down, in the up position it has about 50mm / 2 inches of ground clearance.
the paint is drying and should be dry for the official test run tommorow,

I want to make up a couple of covers for the cables on the blade tilt rams and then the dozer will be finnished. ;)

sure, will post some when I finish work.
The screener is made from an old drain pipe with two different size mesh.
I had an old spit roast motor doing nothing and some old aluminium filter frames.
I now have 4 speed controls, $10 each.
1 for drum speed, 2 for conveyors and 1 for the vibrator motor that is fitted to the infeed hopper.
I made up a control box and fitted a 12v power supply and a 230v supply for the spit motor.
It runs nice and quiet unless there is nothing in the hopper.

There is a quick video on the first or second page of this post, will do some more videos with excavator and screener on my days off.

here's a few pictures of the trommel and a quick video of the gold trommel.
I gutted the black power supply and fitted the board into the main control box, have used banana plugs for the conveyors and motors so it can be transported easily, will one day make the control box into a container so it looks like a generator setup , but that's another job.
the gold trommel uses a portable shower pump 12v to cycle the water but it needs more flow so will look for a high flow pump to replace it one day.
The kids grab some brass dust of the lathe and sprinkle it in the slues box and instant gold.
shame its not worth much but looks good.:D

over the last couple of days Ive been struggling to dig in my chosen area due to the compacted gravel, the dozer can rip most of the rocks but its slow going.
Then I had a brain explosion, lets make a rock ripper bucket.

http://i1322.photobucket.com/albums/u575/andyathome/20141230_161739_zps3ffbb6f4.jpg (http://s1322.photobucket.com/user/andyathome/media/20141230_161739_zps3ffbb6f4.jpg.html)

I ran out of gas and its unfinished but I had to test it.

Magic, digs great and moves the rocks no worries, its a little small and will take a little while to clear away all the rocks but now I have reached the dirt.

got sick of swapping buckets so I made a manual quick change.
started with this .

Good work on the quick attach & rock bucket.

Rock bucket will be great for trenching, but I think a ripper tooth to rip a large area & then use a big digging bucket to clear the cultivated area would go a lot faster.

01-06-2015, 02:13 PM

morning all,
cheers Joe, now that I have the quick attach sorted the ripper sounds like a good plan.
I also have the original bucket , not much good for digging as its lightly made and bends under load.
the plan for that one is hit it with the splitter blade and make a screening bucket, don't know how much use it will be but at least it wont take long to swap over.
cat 322, its the china buy excavator, have swapped all hyd lines for high pressure lines, swapped out the pump and motor, valve bank and esc's for RC4WD set up.
same as my RC4WD excavator, will also have to reinforce a few of the boom mountings as they are pretty light and also need some bushes made.
this will be a test for my young fella to see how good he is using the mill and lathe.
all the hyd parts will be transferred to the rock truck for the tipper and steering,

I got it of the buy china web site, just had a quick look and its now on aliexpress web site.
If I were you I would get the shell and fit rc4wd hydraulics and radio gear.
It is lightly built compared to the rc4wd excavator.
I would also cost it all up and do a compare to buying the rc4wd excavator , I know its not as nice to look at but its a turn key and dig machine that will last longer than the KAT excavator.

That looks like cold rolled steel you're using :thinking:, if so, you'll probably loose your point pretty quick & the tooth will not be effective.

This tooth I made, not very prototypical of anything, but it works very well. Those are 3" ardox nails that I weld on... they wear out eventually, cut 'em out, weld on new ones. The width of the shank is 3mm.

Im going to talk to one of the engineers at work tomorrow and see if we cant put a hardened edge on the ripper.
have made a video and uploading now , I tel you it makes for easy digging once its ripped up and way quicker.
I made the blade so it can be unbolted and swapped out so can try different shapes and sizes, but this one seems to work nicely.
Just need to set up conveyors and start feeding the screening plant, unfortunately im back on shift so it will have to wait.

Do you have dual rates or flight mode in your radio programming? If so, lower your EPA settings for valves & swing so it makes your stick throw on the gimbles less sensitive & you will have much finer control while trying to change attachments. Then you can switch to a different rate of throw for digging.

On airplane radios it's usually just aileron, eleveron & rudder that have dual rates, and with Fmode you can change throttle curve per mode to achieve the same characteristics as dual rates.

When I 1st started rc excavator in 2001, I operated my model much like the way you are now. Something that was said to me by an experienced machine operator after showing him my model, "what separates the best from the rest is how much the tracks move around while digging at full capacity of the machine".

I don't wish to be mean or rude, but rather be helpful to guide you to operate your model with greater finesse & professionalism, it makes watching videos of what you're doing more enjoyable. :)

andyathome

01-10-2015, 12:45 PM

cheers joe, I have the standard flysky radio that came with it, I would like to have a go at changing how much the valves open and swing speed to achieve a slower movement as to make swapping the attachments easier.
Since i never got a manual with the modle i havent messed with the radio settings, figured if I messed the settings up I wouldnt know how to get it back to what it was.
I know it has a flight mode , will search internet for a manual, did you change any settings on your rc4wd excavator to make it smoother and if so do you remember what they were .
as Im new to these multi channel radios I have some learning to do, but am not affraid to have a go now as there are plenty of guys here that are willing to share there knowledge to help an amature like me.

Nice job on the ripper Andy, one came with my 944b but not had chance to use it yet, I didn't think I would but after seeing yours maybe I'll give it a go!

On the radio, I've added curves to the valve channels, so when you move the sticks the valves only open a tiny bit to start with, makes small movements much more controlled, the same curves also ramp the pump speed up.

Keep up the good work

Have just found the manual for radio so will be doing a bit of study. Lucky im at work and no excavator.

Lil Giants

01-10-2015, 02:26 PM

I got a radio manual with my RC4wd hoe, but the English translation was quite poor & didn't offer much sensible info anyway... my model didn't run long enough to let me do much with it.

I recall changing servo travel (EPA) & it being easy to find/to do in the programming, though I don't remember the sequence of what I did today. I think you want to look for either servo adjustment or servo travel to find the EPA values.

While EPA values can be equal on both sides for bucket & stick, I usually program a very low value for boom down because of the effect of gravity... the Vario 850 has a very heavy boom/stick & @100% EPA will drop very fast with very little stick throw... currently boom down is 60% & up is 100%. The boom/stick on your model is considerably lighter, but on the other hand it still has a long boom & stick and gravity with have some effect with a bucket full of dirt... plus your hyd pump & motor is a poorly matched combo, you have too much flow & too much pressure for that size of model.

What I did with my Stahl excavators (22lbs gvw) to set hyd pressure was with the bucket perpendicular to the tracks, set the pressure so the stick could just barely pull the hoe sideways on hard ground (that's with both tracks staying grounded). The pressure was about 16-17bar with a 14mm stick piston. My Vario is just too heavy & that test is irrelevant, even @35bar with a 22mm stick piston, it doesn't have the hyd power to pull itself sideways. I see it advertised that china hoe weighs 44lbs... mine weighed roughly 32lbs with a NiMH 4amp battery.

thanks Joe, i notice mine will drop the bucket like a stone with too much stick movement and it will also pull it around too easily.
I will have a go at changing the epa for a few movements to get it more life like and dehorse power it.

If I read the manual( good translation) Ive got no excuses for messing it up.
but I may still ask some dumb questions till i figure it out.. :lol:
thanks for the advice.

Hiya Andy. Loving your setup you got there. Just one question though. Does the King Hauler pull your 4200xl ok? Was just wondering as i am getting a 4200xl and i am already think about a low loader lol.
Cheers Chris

01-15-2015, 01:25 AM

Hi ya chris. The king is fitted with a pmd 4:1 reduction box (in the retail section) bolts directly to the original gearbox and pulls my 35kg dozer no worries.
there is a youtube link some where on the jcb forum, even pulls wheel stands under load.
I stretched the frame and added an extra set of drive wheels for looks and added traction.
having said that my knight hauler (standard) will also pull the dozer, but not as easily.
once you get one piece of gear you will always need something else. Lol.
keep on trucking.
Cheers andy.

as I have mentioned I may ask some dumb questions, well here is the first one.
I have had a play with the radio settings for the excavator, have managed to slow the rate the boom drops and also the rotation, really happy so far.
problem is that my pump is now going in reverse??
have checked all switch operation and seen how they work in the display screen, all looks as it should be.
pump starts when the switch is operated but in reverse, have reversed the switch but all that dose is change when the pump is on.

any ideas..

Think I got it sorted. Can any one tell me what direction the pump motor turns.
I have run the system dry due to a pump seal leak but have swapped the motor wires around to change direction and now have to bleed the system. Just need to know what way it should turn.
new pump should be here soon then it is back to digging.

Lil Giants

01-18-2015, 08:21 AM

Is the suction line from the tank to the pump see through? Even if it's a black line so you can't see the oil coming from tank, you should still be able to hear if the oil is being sucked from the tank or if the pump is blowing air bubbles into the tank.

andyathome

01-18-2015, 10:33 AM

Yes got direction sorted, pump seal at motor end has been leaking for a while ( new one should be here in days) by the sound of it it is probaly shot. I have arm movement but not enough flow to clear air properly so will wait for post man.
also will flush all lines and cylinders and replace oil as old oil was foaming pretty good.
but I did get to test new ripper.
it works much better with the curve, gets in under the rocks realy nicely.

Im uesing the tellus 15 equivalent which is a dte light by mobil as its free and avaliable at work.
the hydraulic guy here at work recomended it for the application but he insisted on a test drive just to make sure it was ok, that was almost two years ago. So I can say the mobil oil works, no leaks from ram seals.
lf you use an oil that is too light it will cause issues and the same if its too heavy.
got a quote for 20 liters yesterday $120.00 , its the smallest container they sell.
should last a long time.

Cheers for the Help Andy. I bit the bullet and with my teeth gritted i bought some from RCBitz here in the uk. Cost about £36 in the end and thats enough for 2 tank fulls.
My oil guy here at work is going to find me some equivalent hydraulic oil as i wont be paying those prices again lol. Got two 6400mAh 3S1P 30C coming from Hobbyking too and the 4200xl should be here between 5 and 11 days time..Woohoo

nice need picts in the dirt.
i spoke to several suppliers for work and they worked out what i need, 20l bucket is a bit much, but with three hyd models it will , still last a long time.
$30 from rc4wd for two tank fills is way too much.
talking to a fellow dirt bike rider he suggested motor bike fork oil as its pretty close to the tellus oil and should work and you can buy it in 1 liter packs. and its cheap.

all right update time.
have sorted my issues with the 4200.
I had a leaking pump seal, new pump sorted that.
I played with the radio settings and made a complete hash of it.
read the manual, did some more playing and fixed it. slowed the slue and speed the main boom drops :bounce:

had a small problem bleeding the system, worked out one of the problems was I put the tank back in the wrong way around and the suction line was fitted to the return of the tank, so the rams would move , fill the tank enough to force oil into the pump then it would run dry again!!! MUPPET!!!

still , im learning and wont do that again.
radio is pretty easy do use now, so will play around a little more with the settings.
had to test it all out so dragged the screening plant outside and had a play.

andyathome

01-27-2015, 07:54 PM

that's the one Joe, found it by mistake.
good for practising the bucket swaps, I need some more reading time to see if I can do something with the slew as its quite jerky and smooth small movements are quite a pain.
I am wondering if a better esc and motor gear set up will fix the problem, or can it be slowed on the radio, by that I mean the acceleration of the motor.
the mix channel switch seems to only affect the hydraulics , only noticed it as my sound card is controlled by the forth valve( engine revs ) but dosent seem to have any effect on the rotation.
time to get the radio manual out.

cheers andy

Lil Giants

01-27-2015, 08:40 PM

A better esc would be best to try, one with a light to no brake.

The mix has nothing to do with your rotation. You can manipulate your rotation speed & smoothness with the use of dual rates using different values for curves & offsets, and it will help alleviate some of jerkiness, but not eliminate it. Your right/left movements on the sticks are either aileron or rudder, which is which on each side of tx depends on which mode (1-4) your transmitter is set to.

osikasculptor

01-27-2015, 08:42 PM

What I did was screw the dial all the way in on the pressure relief valve then
the dial for that servo can be used to manually adjust the overall pressure/function speed from the radio (mix always off then) This also keeps sound constant- dialed up down manually with pump on or off.

andyathome

01-27-2015, 09:20 PM

thanks guys,
engine revs , I can set max revs on the signal reversing cable ( small pot on board )
Im more focused on the rotation jerkiness ( if that's a word ), I will try joes suggestions on the radio and see how we go.
if I cant get any joy out of that next will be an esc, the more play time with the radio the more confidant I am becoming at changing things up, also learnt write things down before I change too much LOL.
thanks for the help

02-02-2015, 05:20 PM

No. Have checked all the possible mechanical issues and everything is good, it is more of an electrical issue . The smoothness of how the motor preforms on the control side of things.
have ordered a few esc's to see if I can take out the choppyness of the brushed motor, if that dosent work maybe a brushless motor will be smoother .
still have a few projects on the go so can use left over bits for other toys, and you can never have too many spare parts.

finally got motivated and installed the light kit for the loader.
had to disassemble the loader to run all the cable's nicely out of the way ( bit of a mission) but worth it in the long run.
indicators work off steering , even got them on the correct side first pop, left is left right is right.:)
figured out the radio to get them switching on the aux pot at top of radio,
now all I got to do is put her back together and start the digging.

04-14-2015, 10:27 PM

it was time for a bit of maintenance on the junk rock truck as the swivel was sagging , the steering wasn't working too flash and the tipper set up was very sad.

I made up a new dual layer swivel joint .
I made a new set up for the tipper motor and used a universal joint on the screw drive.
I made a cover to protect the tipper motor.
rerouted the drive motor cables under the truck and into the bottom of the cab.
I also filled all the holes in the chassis of the tipper frame.

as for the steering a 6rpm motor was fitted at the back of the cab and a couple of arms bolted to the right places and we have steering!

I found when the bed was loaded with 20kgs it struggled to get started lifting ( may be my geometry is a little off) SO I had a brain wave and made some fake rams to fit to the tipper.
They are filled with two 50mm long compression springs, so when all the way down( tipper bed) they are compressed, this gives that little bit extra and make the lift start easier.

now its off to paint and back to work.

new swivel joint

and how I made the rams, once the springs are decompressed on the up lift the rod just follows the screw drive.

well , its almost winter here in New Zealand and the outside digging is not so much fun, so another project I have wanted to build has been started.
A rock crusher.
I have made the crusher box out of 6mm steel and used a 10mm round bar drilled off set to make a cam, made a crusher plate and tested.
hooked up a battery drill and crushes a beer bottle cap no worries.
heavy duty springs at the bottom of the crushing plate give me a little movement and a bit of adjustment.
It will have its own tracked drive system but will have a generator ( battery box ) to power the two conveyors and the crusher motor.

I may need to use bigger flywheels but that will be an easy change. Once all functioning I will fire up the 3d printer and give it some detail, but the main concern will be function.
I will also make some new crushing plates out of stainless steel which should last longer.
Heres todays progress.

spent a little more time in the shed today.have the bottom conveyor all mounted up and managed to get the second conveyor almost done.
hope fully the rocks will be travelling fast enough to be thrown onto the second conveyor.
need to make a few more bearing blocks and make up a mount for the winch to raise and lower the out feed conveyor.
not far off testing ....

I am loving this build Andy! And thanks for taking the time to share with us. Your moving along so fast, making me feel guilty for time spent on the couch! :eek::lol: i need to get back building and your really helping to motivate me.:cool:

The transition to the second conveyor does look tricky. Definitely need some speed on the first to throw material. Could you elevate the end of the first conveyor a bit, lower the second and slip under so you have a straight drop?

andyathome

06-11-2015, 05:25 PM

hi ya.
looked at lots of options, not too many choices due to space and height constraints.
I need to make a smaller last roller on the 1st conveyor and have made the 1st roller of the outfeed conveyor 3/4 the size.
It will give me about a 20mm drop , so when its up and running i will be able to adjust speed electronicaly to get the throw about right.
at least thats the plan so far. LOL.

I need to get two drive sprockets so thats another $20 a couple cans of spray paint and job done, all up should be under $100 build .
I have some old recivers I can bind to a radio but will need another saber tooth fot the tracks.

Got another 6 days now at work so plenty of planning time.

had a day off due to the flu so spent a few sneaky hours in the shed.
plans have changed again.

my original set up needed a small modification because Im cheap, I didn't want to spend the best part of $300 on a 10 foot length of chain.

so Ive cut off the track set up , mounted motors at the back of the crusher for the track drive.

Have also shortened the length of the tracks, makes it look a little more scale next to the excavator and loader.

I have had to order a couple of motors so cant do much more to get it running until they turn up but can make a start on body panels and finish of tracks.

I will fit 5 or 6 5mm bearings for the crusher tracks to run on and a couple up top to take up a bit of slack.

But the first thing I want to do is make the front half that will hold up the out feed conveyor, nothing too flash but I will fit a winch so I can raise and lower the conveyor.

more time spent in the shed and it still looks the same

main structure is now complete, so it has been loaded onto the low boy to be transported to work to be sand blasted prior to the first coat of primer.

I need to modify the tracks a little due to a lack of planning, have to change the front wheel height because I did my measurements of the drive sprocket which is too small,

but that little mistake turns out to be quite fortunate because it will give me room to fit the bearings under the track body .

also need to play around with the hopper to make it look more industrial, will also put slits in to the bottom of the hopper so smaller rocks will fall down a shute onto the conveyor (and bypass the crusher ) which has been moved back to suite this new change.
have test run the crusher by manualy feeding hard dirt lumps into it and attached battery drill to crusher, lots of dust and little rocks.
looks like it will work nicely.

its going to be a long drive of 50 plus ks to work so I think I will just put her in the ute and save a bit of time , plus I don't have a pilot vehicle of any of the necessary paper work to use the motor way.

didn't get a whole lot done last night, made up a cover for the fly wheel .
I made it quite a bit bigger than needed just in case I need to fit a bigger fly wheel, and also had some major dramas getting the hopper vibrator to move product, had to make some temporary brackets to align the hopper , and will need to make a bigger vibrator weight.
also had a dive into the scrap bins and found some pretty cool bits and pieces to make some vents , grills ect to give it a bit of detail.
last night shift tonight so want to get hopper functioning and looking the part, may be even get a shute made up to take the fines away before the crusher.
one thing at a time. :(

Wow Andy, the crusher sure is coming along great! I can't wait to see and hear it do some crushing.:). I agree on a way to get rid of fines. Won't take long and it'll be everywhere:eek:.
My conveyor started slipping after extended use. The back side of belt collected the fines and transferred it to the wooden drive roller. It had a complete thin layer packed onto it. I realized that installing a brush to clean the belt is not an option but a must! :cop:

Anyway, nice work. Enjoying the build.:cool:

andyathome

06-22-2015, 10:46 PM

I agree with the cleaning brush .
I will make a shute under the hopper to take the small fines down through slits in the hopper and somehow fit a bottel brush ( which ive found in the wifes cleaning cupboard) in between the conveyor belts .
My idea would be to fit them on an angle in between the belt? So dirt ect was pushed out to the side.
dose that sound like the right idea.

cheers andy

Supermario

06-23-2015, 09:31 PM

I had the same idea to place on a angle to clear the dirt. If it's straight across all the fines will bunch up and get by the brush.
Which reminds me, had a crazy thought as I'm sitting looking around my man cave and saw some wiper blades I've been collecting to use as treads on the conveyor if needed. I might try to use a wiper blade? I'll take some pics and show you what I mean.

but since I didn't have any motors I decided to paint it.

no sooner had I finished painting it I hear " hi mate , got a package for you .

if learnt something today, if you use a mig welder to weld galvanised fence wire you are lighting a fuse.

Ive welded galv steel before and its not that great, clean the galv off and its not too bad. but the wire just started burning and fizzled out about 10mm shorter than what I started with.

plan B was needed , I had a length of tig welder filler.

cut and bend to suite and weld with mig , works nicely.

Unfortunately I only had 1 length so got to get some more to finish the safety rails.

Bob seem impressed with the crusher.

this is where the main conveyor drive will be

hey Justin heres a real quick video of the crusher crushing dirt lumps.
just fitted battery drill to shaft and had it set on low 0- 400 rpm, it appears to work better at the higher speed but needs conveyors running to take away the crushed dirt as it blocks up with out them running.
the crusher motor is a 1200 rpm unit so I can slow it down on the pot on my power supply box.

heres test #2 , big rock ( hard dirt) may have to change crusher plate to make gap smaller at bottom but first I need my conveyors running so it has a chance to break the lumps.

I think the problem is that the dirt is pilling up on conveyor and dirt isn't going far enough into jaws to be broken down.

I think once the conveyors are running and there is weight ( more dirt) on top of the rocks in the jaws they will be forced down the shute to be crushed.

heres a quick video , let me know if my theory is right?

Your right Andy. The more in the chute the better. Crushers are hungry and need a steady flow of material otherwise single chunks will skip and dance around. That's cool if you can easily adjust jaw distance and crush different grades or size of material.:cool:

Your screening holes prior to the crusher, I've discovered the fines help move the chunks around in the box, constantly changing the bite of the jaws. Sometimes chunks lodge & stay in one position, then the jaw pivots on that one chunk, not breaking it any further.

O rings for belts... to drive your crusher? Won't last very long, they stretch too easily. Cog belt or V belt with steel in it.

andyathome

07-01-2015, 01:40 AM

I have been told the same about the fines shute.
we have a guy at work who used to repair them in South Africa and he suggested a sliding mech under the hopper slots that I can adjust to suit the material im crushing and that the shute must be full to work properly. And apparently it needs to lift the rocks on the jaws when crushing other wise they will jam in place.
I do intend to use a toothed or a vee belt but I had the seals ( o rings ) lying around so for initial testing and a zero budget they will have to do for a couple of weeks.
this has been a bit of a learning curve but still fun.
by the way Ive also learnt that you dont put a large plastic handle of a screw driver into it to see what happens.
I now have a large square shanked handle less screw driver and lots of yellow plastic bits.

Never realy measured it , but im guessing around 6mm.
the top moves more than the bottom of the crusher plate..
I also need to change the shape of the jaws to a rounded shape so the majority of the crushing happens in the middle of the plates.
there is a lot more to just smashing up rocks.
my design is a little different to a real jaw crusher but it actually works.
maybe I should pattern my design LOL.

just a small up date , got all motors mounted and tested.
track drives all good .
a few hand rails to go and a total repaint, also still having trouble finding drive belts that im happy with.

Also picked up a king hauler day cab with a wedico 3 stage hydraulic ram on a home made tipper trailer , needs some loving but that's what winter is for.

any way heres some crusher progress

As fast as it seemed to initially go together, I was hoping to see a video by now of it breaking rocks? :thinking: :D

you and me both, but the mrs dosent quite share the same enthusiasm , hence the jobs that need doing around the farm.
now that the fencing is all finished and creek cleared, did I mention trees cut down and made into next years firewood......

I now have a few days play time, I need to find some closed loop timing belts for the crusher drive as the home made ones don't last and my initial orings were never going to be permanent .
I will measure up what I need and order them and also make a start on the control wiring.
I want be able to drive tracks via rc but want to use my power supply to run vibrator, conveyors and crusher motor.

still waiting for some belts to show up for the crusher , so I made a start on the latest project.
I picked up a second hand king hauler with a home made tipper trailer , which has a 4 stage wedico hydraulic system.
the plan was to clean it up and a quick paint job....
the previous owner wasn't too kind to the truck and a little rough in the building side of things.
so the plan changed a little, I was going to make a trailer and fit the hydraulics but looking at the truck , as a day cab it looked too long.
plan B , make the truck into a dump truck and make a smaller pup since Ive already ordered some axels I might as well use them.

heres a few progress pictures, The cab will be lowered as all the plastic parts holding the cab were broken of butchered.

lots of sanding to finish off tipper body and then its the tail gate to make.

got a little more done on the dump truck.

not overly happy with the tipper body, due to a little warping when welding.

No gas for the tig so had to use the mig, blown a few holes here and there but nothing a little filler wont hide.
I will also replace the plastic tanks and make two stainless ones so that one of them will be full of hydraulic oil and the other possibly to hold the pump.

its been an interesting week, the mrs has been laid off , new parts are turning up daily for the dump truck and pup build and the dogs ate the spa pool cover and chewed through the spa pool power cord when it was turned on!!!!! :(
what do ya do...:o

Ive also got another wedico ram and pump coming from a fellow RC chap in ausie , so pup will match the truck. :D

got some more sanding to do then it is the big decision on colour choice.

enough talk heres a few pictures

So what size wire do you run in your mig? I have .023" in a small hobby mig & welding light gauge works very well.

So... did the dog(s) get electrocuted?

andyathome

07-26-2015, 01:13 AM

Im useing 1mm wire at the moment but have several different nozel sizes.
would usualy tig most of the time as I can weld better with it and less chance of burnning my shed down.

and as for he dogs, they are lucky they are alive either way. :)
just got back from a four hour round trip to get another spa cover .

cheers andy

Yeah, I use 035" wire in my 200amp mig to do my various farm welding tasks, that's a bit smaller than 1mm. The smaller 023" wire takes less voltage to melt & splatters a lot less too... so what do you use the big wire for?

Really enjoying the updates on the crusher, its really taking shape

Do you have any pictures of the jaw setup? I'm thinking to make something similar and I was wondering how to attach the jaw at the bottom?

What speed are you going to run the jaw at?

Hey joe. I use the mig to do structual things, roll cages, chassis mods.
what ever the guys need. Running high amps and a good sized wire is more forgiving on heavier structual steel.
I used to race off roaders running a turbo charged subaru engine , did pretty good but now its time to spend more time at home.
broke too many bones racing cars and bikes.
I still look at the trophies and think I could be the ledgend again, but the cold mornings remind me im not 20 years old any more.
Would rather help the young crowd and try and pass on a bit of advice.

I do love my small 3 in one tig/ plasma cutter/ stick welder awesome for most jobs, just need some more gass.

ok , colour choice for the truck, real simple.
checked cabinet for spray paint, only had black.
so truck is black.
also sprayed dump in the aluminium.
need to start fitting some exhausts ect to break up the black.
Ive sprayed most of the chrome bits in aluminium paint , and it dosent look too bad.
the steps ect that came with the truck were all corroded and needed painting, also when I make up the hydraulic oil tank that will get the aluminium to match.

fresh out of the paint shop :)

cheers , its defiantly no beauty queen, but it aint too ugly :D

got a bit more done due to average winter weather, sprayed the plastic chrome parts in aluminium that I will be using and fitted.
I don't know whats on the windows but nothing takes it off so may have to order some new glass.
I will make some exhausts and air filters ,I also made a start on the trailer.
cant do much more until my wheels and axel turn up,

heres a picture update
