Started building the PC1800 with a plywood profile the same way that I started the D11 and 777 build. I will be using the original tracks I had on the dozer but will need to add 10 more links and pads, keep in mind I'm not building a true scale model of the shovel but will try to keep it much the same as full scale.

I have made some progress already with this build and will upload more pics and info in time.

I will be using a sprocket and chain for the swing , this will allow me to put the swing drive motor in under the cab or in a spot that is not needed for something else.

Still need to install the top and bottom seals on the bearing as well as the spacer to get the proper height. Hope this all works...LOL

I will be trying these air cylinders on the shovel not sure how well they are made but I'm going to find out. The main boom cylinders are 1.25" ID and the rest are 1.0625" ID. Hopefully the 5/32" tubing will have enough flow.... I'm going to find that out as well. :D

I also plan on using a full scale valve body and pump , I will need to change the operating pressure in the valve down to 200-250 psi and the pump will need to turn at about 1500 RPM to supply enough volume for the cylinders, not sure if I can get this all to work as I would like but it's worth a try...the other challenge will be getting it all to fit in the model....time will tell.

Princess Auto strikes again!lol I'm liking what you're up too! I think one of the other guys on here used some valves like that in a couple of excavators and they worked alright. What is the plan to spin that pump with? 3408?lol

http://rctruckandconstruction.com/showthread.php?t=3616&highlight=pc650

Yes good ol princess auto...lol...the valve body and pump are from them (got them on sale too heehee) the cylinders are from Automation Direct. Not sure yet what motor will be used on the pump yet, need to turn it at 1500rpm to get the flow needed but I don't actual know how strong the motor needs to be, if I put in a motor that is to big it will just eat battery power. Still need to try runs some tests with pump RPM and see what flow rate is like, going to just use a cordless drill to do the tests on the pump three speed drill will give me some ranges to play with. You would need two 3408 engines to run the full scale shovel.....even then two kitties might not be enough....lol

Thanks.......it looks simple enough but was tricky to make....my first mistake was using a three jaw to turn it , should have use a four jaw but got lazy and didn't change chucks and started to get some vibrations in the cuts near the finished size, sometime short cuts aren't short cuts at all.....just end up spending more time trying to fix thing.

Since I'm a Komatsu guy, I've been waiting for this build to start. Great work on the swing bearing! Don't know if it will be a problem, but sometimes when a main relief valve is adjusted well-below its normal operating pressure, it is not very consistent or accurate. I'm guessing this system has an original pressure of 2500-3000 PSI, dropping to 250 PSI might be a problem. Hope it is not for you. Should you need additional technical information about the full-size PC1800, let me know. Be glad to assist.

Ken

You might be right about the relief valve not liking the the low pressure, I wasn't thinking of that style of relief valve in there not a simple ball and spring, if it wants to float around at the low pressure I will need to add an external one on later to correct it....l will try it first and and see what it will do...maybe just maybe it will work with the low pressure.
Do you work on this machines or operate them??

I agree with RCP-I want to see everything!! A scratch build and a front shovel. It just doesn't get any better than that for me. I prefer the older cable shovels but I guess they are on the way out. Hydraulic machines take a lot more maintenance and do not last half as long but I understand that is what the companies want today.

Wow, great work on the swing bearing!! I've tossed around the idea of making bearings. Can never find the right size and if I do it's $$$!!! Yup, keep the pictures coming, I usually post pics because I need a break or because something just isn't working out and it's just enough to walk away and regroup:). Speaking of that, how is that motor gearbox holding up on the haul truck? This front shovel is going to be a big boy!! Any guess as to how much it may weigh when done??

Thanks....I was originally going to buy some big tapered roller bearings for the swing bearing and like you changed my mind after finding out the price, so desided to try build a bearing (was most likely cheaper to buy the bearings if a person considers all the time spent in making it...lol) one thing I like about it is it will transfer the load over a big area unlike some of the models using a small bearing. This model will be heavy and if I did the math right should be able to lift between 80-100lbs or I could just be fooling myself into believing that! :D

The banebots motor gear box has held in there so far, have stretched the#25 chain and have needed to tighten it a few times but the motor hasn't given any troubles yet...knock on wood...you know how that works...watch the next time I use it something will pile up :lol: I want to tear it apart and look at the gears and see if there is any possible failure about to happen, or at the very least clean it and apply new grease....pulling the motor out of that truck is not much fun so I think that's why I haven't yet;)

Not sure how heavy it will be, if I had to guess I would say it will be in the 140-160lbs range but I could be completely out to lunch on that guess, may even end up being heavier...lol...knowing the size of it and the way I build stuff it will most likely end up being 200lbs HEEHEE

Awesome!!!! Now I know who's brain to pick for info!! Finding good reference pics on line for this machine has proven a challenge....so I'm cheating a bit by looking at the PC2000 which has a great deal of similarities to the older 1800. I was almost going to switch the build to a 2000 but decided to keep going with the 1800. One thing I like about the 1800 in the length and size of the body/house section, gives more room for the full size valves etc, the modular design of the 2000 just wouldn't work. I do however like the overall looks of the 2000 over the 1800 but the design of the 1800 will be somewhat easier to build.

Is it OK to post reference pics from the online Komatsu brochure of the shovel...I would like to post one of the pics with all the size references on it ? Or if anyone else knows the answer let me know....that would be great !

Not an expert, but if wanting to post something that is from Komatsu's public website, I'd say no problem since it is not being using in a derogatory or for-profit way. Might list the link you got it from.

Finished putting the swing bearing together c/w seals and spacers, needed to add spacers to bring the overall height up to what was needed, I didn't have thick enough material to make the bearing tall enough to start with so it will be 4 pcs total instead of two.The total height of bearing c/w spacer is just over 2".

Howdy Joe......to bad I dont have any fan motors around like that,would almost fit....LOL....just need a long extention cord and never charge another battery.:D

I did run some red neck, high tech tests using a cordless drill though :p....turns the pump at about 1400 RPM no load, at that RPM the pump is moving about 51cc / sec which is a bit more than I need, could slow it down a bit more.
2.2cc / rev X 1400RPM = 3080cc / min. Rember this is no load very little restriction in the system ( I did need to increase the intake hose to 5/16" ID hose, the pump did not like trying to pull that much oil through the 1/4" OD tubing which is what you see in this picture)

This was the next test c/w valve and one 1.0625" ID x 6" stroke air cylinder, I have a 40lbs load on the cylinder. I replaced the spring in the RV with a lighter one that I thought would work and with a small adjustment it holds the desired 250PSI very well , really glad this worked :D:D This valve has an open center which means when all the spools are closed the flow is allowed to return to the tank with very little restriction which should help increase run time on the battery.

Great project, thanks for posting) When able to scratch build a fantastic swivel bearing like that, I was betting you also would be building scale replicas of the original cylinders;) But hey, if there is already some stuff out there on can get hold of that is about the correct size and can take the pressure, one can save time naturally.

Thanks!! Decided to try use some off the shelf air cylinders that are close to the needed sizes instead of building them, time will tell how well they will work and or for how long...lol

I have a question or two for all you hydraulic fellas on here.....

What type of oil filters are being used in models , are there inline and intank
filters??
How much would these small filters effect the flow if the needed volume is greater than the typical RC system??

How big should the tank be in regards to the total volume of oil in the system, should the tank hold the same amount or more, or can it be less providing the oil temp doesn't get to hot? I can't see the temp of the oil in this model being a problem....there will be about 700cc in the system not including what will end up being in the tank, which is one more thing that still needs to be built. I would think that the longer the model is being used the warmer the oil will get....how warm does the hyd. oil typically get in your machines??

I have limited knowledge in regards to hydraulics and no experience with RC hydraulics...zero...so be patient with me as I hope to learn more from all of you and of coarse the good ole " school of hard knocks"

RC_Dozer

12-02-2015, 01:50 PM

Hello Dadsgarage,

In a normal machine, the tank volume is about the same size as the system volume. I would do the same on a model. Maybe a little more to be sure and to have better cooling.
Unfortunately I do not have experience with oil in scale models yet.

Your build is great! I really like the scratch build parts.

12-02-2015, 02:21 PM

i alway thought it was double the cylinder. 30 gallons in the piston
30 more in the tank. thats how it is on my dump trailer 60 gallons
in the tank when the piston is down 30 left when full lift.

what about a inline carb filter on the return side as long as it not under pressure

I wanted to use this (fuel) filter in my stuff but it is too big, probably good for this size model. Oil filter/fuel filter, they both are trapping particles of a certain size, 5~500 microns,,, the ones I use are very small disposable I get from McMaster. I have to drill out ends and thread for m5 fittings. I'm sure they are way too small for this. My opinion on hydro volumes is about same as above, double the system volume and you'll be good. On an hydro guys side, as big of a tank as weight/size/practicality allows. More oil is just better all way around. Temp, contaminants, lifespan of oil, ect. But on 1:1 machines, lifespan, cost of replacing, and available size is what restrictions are. One thing to try is to have tank suction on bottom and tank return line on top (baffle or just opposite side) allows air in oil to migrate to top and not back into pump. That's the frothing of agitated oil, a lot of oil has additives to lessen foaming. I've never had temp come into issue in any of my models. Excavator cylinders get warm after a hour use in summertime, but never hot. (At least that I am aware of:) )

And that school you talk about, one of the best I've ever attended!!! :)

Thanks for all the feed back on the hydraulic questions, now I will have to put it to good use....

Next trick will be getting everything to fit, even though this is a good size model there isn't a lot of extra space left over after all the "big goodies" are in place. Played around with different placements of everything on a plywood template, this seems to be about the best use of the space....the rusty 2"x4" HSS may end up being used as the tank, after getting a good cleaning and cut to proper length it will hold about 1000cc. I dont have the drive motor yet for the pump, it will be belt drive with about 3:1 reduction using a small 2L vbelt. The servos will be mounted on a plate above the motor/pump, the handle shafts on the valve will be cut shorter and then connected to the servos with ball linkage rods. Nothing to exciting but here are some pics....

How many amps is each battery?

JAMMER

12-05-2015, 11:24 AM

Only a suggestion but why don't you go with an aluminum tank it would seem to have better heat transfer to help keep the oil cooler. Ed

Cooper

12-05-2015, 02:24 PM

Wow, you definately know what you are doing,,,, I'm curious to know how much force will be needed for the valve handles. The shorter you go the more force. I'll have to wait and see how you RC the valves, I'm assuming the hitec servos will be used. Short as possible arm or linkage. Again not questioning anything about your plans, just can't wait to see!!! Lol!! It seems like whatever we build, at first it appears to have plenty of space. Then when components start being placed all that space suddenly disappears!!

Cooper

12-05-2015, 02:31 PM

Just thought of something, on the valves, I assume they are spring loaded for neutral centering. Just a thought but having a servo being used, that would basically take place of the internal springs. Could eliminate them and have very little force needed for throw.

RCP57

12-05-2015, 02:37 PM

I believe the other guy removed the springs and mounted the servos more direct. I could be wrong though. It's happened before....:confused:

DADSGARAGE

12-05-2015, 04:44 PM

Joe, the batteries you see are 14ah each, the space under the cab could be used for one more battery if needed.....

Ed, yes an alm. tank would be much better....I can't weld alm. sold my tig a while back didn't use it enough....could have used it now...lol

Cooper & RCP57, Not sure that I really know what I'm doing but hey as long as it looks that way it's all good...lol...
The very first thing I did to the valve spools was to remove the springs, way to much force needed to move the controls with them installed, without the springs there is almost no resistance when moving the spools. Yes I will be using four Hitec 755 servos to control the valves, which should have plenty of torque and enough throw with big control arms. Originally I was going to remove all the valve control handles and housings and connect the servos more directly to the spools but then the ends of the spools would be xposed and getting any dirt on them would be bad, so that would mean haveving to build something to cover/seal the exposed spools. So using the "KISS" formula.....adapting and using what is already there seemed to be the easiest and most "simplistic" way of getting it to work. I might not cut the original control lever shorter because they will only need to be about 1" long so I will just thread some 1/4" round bar to match the original male threads of the long control lever/handles, then drill and tap the other end 6-32 to attach the ball links....or at least that's the plan for now...time will tell if this all works! :)

Built this cart/work bench to help organize all the "stuff" when doing a build, it has ten small removable parts trays for all the little parts etc. Even though it really isn't part of the build it will help with it...... never seems to be enough bench space for all the parts etc, this will help keep everything together and help avoid collecting all the parts on the main work bench. Usually my work bench is just a magnet that attracts everything but what you're actually working on...LOL

I know exactly what you are referring to with parts scattered!! For a long time I keep wanting to get another cart, or make something like you did. But it becomes another thing to build and gets put on the back burner!!! One of those things that should have been built along time ago and still not done!!! Come springtime I'm going to be moving the shop to another house, maybe then I'll take the time to better organize!! I keep seeing workshops like yours , where things are organized and clean, and I can only imagine what I could cluster up in a short amount of time!! Lol:)

Cooper, the only reason you see pics of a nice clean work area is because many of us or at least I do....is to push everything of to one side into a big pile and then avoid getting it all in the picture...LOL

I put aside the hydraulics for now because I'm waiting on some parts to show up, which is good because it's giving me a headache trying to get everything to fit etc. So here are some other pics of what I have been able to build in the past while....

Jammer, I do sleep at night...lol...these are pics of what I have done over the past few months, I wish it was going together this fast....sadly that is not what is happening, if I get this done in the next year I'll be doing good...lol

Cooper, yes the pattern on the sprocket is etched, the machine operates at about half the normal cutting pressure and the travel speed is also increased which means it just doesn't have enough time to cut through the material, it does have it's limitations and the depth of the etch isn't really something that you can change, it is somewhat of a default setting.

I will be using one solid slider instead of bottom rollers, didn't have any black plastic...and yes I was using a drill chuck to hold the end mill while cutting the UHMW plastic:eek:....I was trying to make the sides look like what I think is called a full rock guard, kinda killed two birds with one stone with this idea just wish it was black, not sure how long plastic paint will stay on them, may need to do them again using black plastic....or down the road I might replace the slider with rollers, really want to see if and for how long this will work

Thanks Modelman, trying to get a few details in this build but my stuff usually ends up looking a little "plain jane" because I run out of patience near the end of the build.Tracks can take a long time, even the simple ones on this...glad to be able to use old ones from the D11.

I was going to suggest that also, can't find the info I ran across sometime ago about painting/dye plastic , acetal. Someone painted something non important and then they used dye on another part. The dye penetrated a little bit verses the paint scratched off. It might even have been a thread on anodizing?!?!??

Made a little more progress on the brass hydraulic fittings, got them turned/threaded. Then they were threaded in until they firmly bottomed out on the face of the valve body, this will insure that the angles are milled in the proper direction and that all of the small fittings for the 5/32 tubing are all pointing forward. Next job will be to mill all the flats and then drill/tap the hole for the small fittings....

The ports and fittings will need be numbered because the valve ports will most likely all have different thread start timing.

RCP57

12-18-2015, 08:14 AM

He means each fitting will be machined to fit a given port because the threads will be cut different in every one. If he just makes the fittings and threads them in to any old hole they will point in different directions when tightened down.

Looking good KP!

What??? haha sorry Joe...I see Reg already nailed the answer for me...I even understand it better now...lol...Thanks Reg, well said!!

One other thing that would affect the orientation of the fittings would be the location of the bottom face in relation to the length and start point of the threads on each fitting, any changes to that would allow the fittings to rotate more or less before it bottoms out on the valve port face. And I know none of the fittings I made are exactly the same. :o;)

The advantage of cutting parts on the waterjet table was very handy....but at the moment both my tables are in storage...long story...never team up with a big company, it seems the bigger the outfit the harder it is to find the right people to manage it, which creates a lack of direction or in this case a change in direction, so for now the machines are in storage. That would be the short and not so sweet version of the story...lol....but hey such is life.

So.....I'll be a bandsawing, drilling, milling, zip cutting, grinding machine for the rest of this build :eek:...or maybe I'll just get someone else to cut the parts!?:D

This is my simple attempt at building a slip ring....hope it works!!??

Used copper pipe for the rings, one wire will get soldered to the inside of each ring and exit out the slot in the center post. Originally I was only going to use one contact bar/finger on each ring, the new idea has two points of contact on each ring which should work better and the tension on the rings can be adjusted by simply bending the brass contactor arms closer together if needed.

The center post will be mounted directly to the bottom of the body floor and rotate with the house, the stationary contact finger assembly is mounted to the center track frame. Each track drive motor will be connected to the brass leads on the assembly. Really hope this works!!
Not sure how long the copper will last against the brass fingers, and I don't really like the idea of two different metals being used on this but the copper pipe was the easiest way to build it and would be easy to replace if it wears out to fast

What a beautiful setup for a slip ring. Just put a generous coating of dielectric grease on the copper rings to stop pitting and it will last forever!! And it looks to me like that Alberta loonie is shrinking smaller with every picture, go Justin!!!!!
Rob

I was going to suggest the same thing as Rob... the slip ring in my JD850 is somewhat similar to yours Kornel with brass contacts, before adding the dielectric grease the friction created a black soot on the contacts creating a loss of electric connection... not a moments trouble since 4yrs ago.

Did some more "high tech" testing of the hydraulics....turns out it does work but not as planned...lol...the open center valve is not the best for running more than one function at a time, live and learn, need to convert it to a closed center which will mean the PRV will be bypassing all the time when the controls are in neutral instead of free flow back to tank when using an open center valve.

Started testing with 20 lbs and then added another 20lbs to see what it would do with the 40 lbs....the extra weight made little to no change in cycle times or pressure

After running it with the 40lbs I noticed the 1/4" threaded rod was bending under the load, so went back to using only 20lbs for the "wire and wood" testing...lol

The motor and belt drive seems to work well, using a small adjustable pulley on the pump so the RPM of the pump can be changed a bit while using the same input RPM of the motor

So what pressure are you currently running at?

So you can't feather two valves together at all for simultaneous movement?

I don't fully understand the open/closed concept, but I'm pretty sure these german made rotary valves are open center, as there is two return lines off one side of the valve; one goes through prv & the other direct to tank. Precise movement of the tx & I can get all 3 valves to work together.

The PRV is set at about 275psi, the operating pressure was about 210 PSI

Yes two valves can be used together but the speed of both functions changes as well as the pressure, I can understand the pressure change but flow should remain constant no matter what the pressure is.....a positive displacement pump (gear pump) that delivers say 2cc per revolution should always deliver that amount of oil no matter what load is on the system,what will change is the pressure and the speed the oil needs to travel through the system....

In an open center valve all the flow from the pump is allowed to flow "freely" back to the tank when the spool valves are in the neutral or center position...so my thinking was that it would be a good way of eliminating the use of an ESC on the pump to gain some battery run time, the pump would always be running at a constant RPM and would take less power to just keep moving the oil in the system unrestricted when no function is being used, instead of always having a load on the pump and motor when using a closed center valve that needs a way of allowing the flow to get back to the tank using some type of unloading valve....but a closed center valve system always maintains a constant pressure in the system which is set buy the unloader valve or PRV, the open center has almost zero pressure in the neutral position because there simply is no load or restrictions in the system which is good in one way and bad in other ways.....

DADSGARAGE

01-10-2016, 06:09 PM

With all valves in neutral and flowing back to tank what kind of pressure is in the system? I'm just wondering, some systems use a slow return check valve for the oil returning to tank. It keeps the valve in a more charged and ready state. Using a flow control you could restrict return flow to a point and not generate excessive heat. Let's say you have 50psi in a free flow state right now, using the flow control you could increase that to maybe 75 or 100 psi and see if the functions improve? Also, your prv would need its own dedicated return line to tank and not tee into the valve bank return line.
It may be something to experiment with before going through the hassle of converting to closed centre system?

Funny you should ask that...lol....because the more I restrict the return line the better it works....lol....(the return pressure was about 60psi) but this is only helpful up to a point....if all the valves are open and the return line is too small the sytem pressure goes way up and beyond the PRV setting, which is what should happen because the PRV valve uses the same return line and there is no place or volume left over in the return line to dump the flow and or unwanted pressure.....but like you say if the PRV had its own seperate return line before the valve body the pressure in the system while in neutral could be increased but never allowed to go above the PRV setting.

From what I understand changing this valve to a closed center should be easy......need to change out one fitting.....the closed center simply uses a plug to block the center port flow to the return line port....when the plug is installed and the controls are in neutral (center position) all the flow must pass through the PRV and back to tank. I'm sure you already know much more than I do about hydraulic systems and don't need to learn anything from what I am sharing as I slowly learn more on the subject, I'm sharing this more for others who might also be interested in learning more on this subject. We can all be thankful and learn from the skills and knowledge shared here on this forum....like Joe says "the more you share, the more you get"

The hydraulic stuff can get confusing very quickly. Yes, a fixed displacement pump will deliver same volume for same pump speed, but if divided between circuits, each circuit gets only a part of that volume, so each function will be slower than each individually. Also, for a given valve opening, oil volume is directly related to pressure on that circuit. If using two circuits at once and both valves are opened the same amount, the circuit with the least resistance (and lower required pressure to move it) will move first. Only when that circuit bottoms out or it's valve is closed, will the other (higher required pressure) function move. Throttling or feathering the two valves during operation is the only way to compensate so both functions can move simultaneously while operating at different circuit pressures. Pressure-compensated (and usually with variable displacement pumps) take care of this for operators, but are much more complicated systems. Yes, the open center system does reduce heat and horsepower needed when in neutral. But having some "standby" pressure, as Mario stated, does give quicker response when activating. Also, open center may allow a function to drop a bit when first pressurizing a circuit - I don't think our model circuits have load-check valves to prevent this.

Ken

Yup....it does get confusing very quickly for me!!! Lol
Here is what I understand....if a pump at a given RPM moves 2 gal/min is attached to a cylinder that has a total volume of 2 gallons it should take one minute to fill the cylinder....if you have two of these 2 gallons cylinders it will take longer to fill them both, in this case twice as long. The larger the total volume of the cylinders being used the longer it takes to fill them all and the cylinder movement speed will be reduced accordingly. What I don't understands is why this isn't happening like it should....this pump supplies much more volume than what is really needed....there should be a surplus of volume left over when using multiple cylinders....but where is this surplus going??? I think that in this valve body there is always some flow allowed to bypass the spools and flow to the return port even when the spools are totally open to the cylinders!!?? One would think that all the flow would be channeled through the spools that are being used and only allowed back to the return through the return hoses on the cylinders. Yes/No ???

Interesting?!?! Have you confirmed the volume of oil being supplied by the pump? Disconnect the return line at the tank and put a container that is calibrated or that you can measure the actual quantity easily. Depending on how large your reservoir is, run the pump without actuating any circuits and measure the amount returned. May have to run for only 15 or 30 seconds, but confirm pump delivery. What pressure is being displayed during this test? Confirm system maximum pressure will make 275 PSI. Bottom a cylinder (either direction) by fully stroking control valve and see if relief valve actually is 275 PSI. Also, at this condition, return oil volume should match max output of pump. (You may see a slight decrease if the motor reduces RPM while under relief pressure, plus no pump is 100% efficient. Most big gear pumps can be up to 98% efficient when new. I'm guessing yours should be near that.) When you saw the system operate at 210 PSI, was that while cylinders were actually moving? Should go to 275 PSI when cylinder hits end of stroke. If there is a question about individual circuit flow, disconnect a cylinder line and put it into a container for measuring. Stroke valve fully and measure volume delivered to circuit. At same time, see if any oil is being returned via the valve return to tank. Should be practically nothing. If is significant amount, the valve may have something going goofy. Also, observe system pressure at this condition.

The best thing for me to do is share the results of all the different tests so you all know what is happening.....

The pump "should" be moving 3000cc/min or 50cc/sec. The total combined volume of the two boom cylinders is 241cc, so at 50cc/ sec it should take 4.82 seconds to fully extend both cylinders. Keep in mind this does not account for any slip in the pump and would be with no load or restrictions.

20lbs was used for the load in all the tests

First test

1/4" ID suction line tank to pump, the blue1/4" OD tubing from pump to valve body, the ID of the tubing is .180", the same 1/4" OD tubing was used on the return from pump to tank. PRV set at about 275 psi on a 0-600 psi gauge. System pressure with no load and the controls in neutral was about 60 psi. It took 7.5 seconds to fully extend both cylinders and pressure was about 220 psi.....funny not what I was hoping for...lol

Second test

Changed the suction from the tank to pump up to 3/8" ID and changed the return line from valve to tank up to 3/8" ID as well. Pressure in the neutral position was now zero, and operating pressure dropped to about 200 psi. The time to extend the cylinders increased to just over 9 seconds. So I was getting some restriction in the return using the smaller tubing...interesting.

Third test

Increased the feed line from the pump to valve body to 3/8" ID tubing....no changes

Forth test

Check the flow rate of the 5/32" OD tubing (.106" ID)....removed the 3/8" return line and installed one 5/32" OD tubing. With the controls in neutral I turned the pump on for 30 seconds (220psi) and got almost 1500cc which is 3000cc/min, again not what I was hoping for...lol....really thought the small tubing was restricting the flow to the cylinders but that is not what is happening.

Test 5

Increased pump speed 600 rpm to 2000....again very little change....scratching a hole in my head with this one...lol

Last test

Dropped the pump RPM back down to 1400, increased suction to 1/2" ID used the same 3/8" line pump to valve but reinstalled the blue 1/4" OD tubing on the return....the result where nearly the same as the first test. Which makes me think that some of the flow in this open center valve is still bypassing the spools even with them fully open to the cylinders. The pump is supplying the proper amount of flow but if all of that flow isn't getting to the cylinders where is it going?? (and no there isn't a leak some where...lol)

Pressure makes a dramatic difference in hyd speed too... looking back to pg1 I see the size cyl bores you're using are 25% bigger than my 850 hoe that has its working pressure at 475psi, but your front shovel is likely going to be 25% bigger too... try your cycle speed tests at 450psi.

Hey Joe.....yes pressure does have its advantages....the only way to increase pressure with what I'm working with is to increase pump RPM, if the resistance or load isn't there the system will not make more pressure. The open center valve pressure with the controls in neutral is zero...I'll bet with your system the pressure is always at operating pressure. This build might be bigger than your 850 but I'm hoping to run it on half the pressure, so I have over sizes the cylinders to somewhat compensate for running a lower operating pressure...this may end up being a bad idea....lol

Speed in hydraulic's can only be changed by two things, pump rpm and volume of oil. The pump is designed to give max cc at the max diameter hose that can be fitted to the pump output.
If you put on small hose it acts like a restriction in the circuit. Also to get max flow every hose from tank to pump to valve and back to tank has to be the same diameter or you'll have the same restriction in the circuit. If the pump is the same as what I think you have the inlet and outlet in 9/16" Dia. =1.767 sq. in. Sizing the hose down to 1/4" .785 brings you down to about 2.25 less volume than the pump can produce = slow cylinders.
I think if you up size all the primary circuit hoses to the proper diameter then you'll able to control it from there with motor rpm.
Hope this helps.

Speed in hydraulics can be changed.....but the pump RPM is directly related to the output volume, so short of up sizing a pump the only way to increase volume flow is to increase the pump RPM. The pump I'm using is really much to big for what I'm using it for so I don't need the max output it can produce....you are right about creating an unnecessary restriction due to under sized hoses but the current sized plumbing is actually within the proper sizes for the flow rate, there are oil flow speed charts that can help in getting the proper combination of flow, hoses sizes and the ideal flow of oil in feet/second....suction is the slowest, pressure lines are the fastest and the return is a bit slower than the pressure lines. The ideal oil flow velocity according to the charts is....suction 2-4 ft/sec, return is 10-15 ft/sec and pressure lines are 15-25 ft/sec...this is for full size systems but I would think the same would apply to smaller scale as well. I think the problem I'm dealing with isn't the flow from the pump but more about where its disappearing to....not going to the cylinders...it's either the PRV or valve body not doing what is should .

I noticed in a couple pictures the suction from tank to pump you had to use a reducer. The larger the suction line the better otherwise the pump is trying to suck through a straw and will drastically effect output.
One other thing that quickly comes to mind is the prv you are using. It is the original valve relief? What is the maximum working pressure of the valve?
The reason I ask is, if you have a circuit that uses a 5,000. Psi relief but you install an attachment like a clam or grapple which only needs let's say 2,200 psi, you can't just turn the 5,000 psi relief way down to the lower pressure. It must be replaced with a lower value relief.
Long story short, maybe the relief is rated too high and working at 275 psi is causing it to not work properly.

Haha...you have a good eye for details....yup it did have a reducer, at the time I only had some 1/4" ID tubing and didn't have a 1/4" barbed fitting...but I did have a 5/16" barbed fitting and short section on 5/16" fuel line so I had to improvise....lol....used the 5/16 barb fitting and hose and pushed the 1/4" ID clear hose into it, knowing it was just a suction line the fit between the two hoses was tight enough to do the tests...got to do what you got to do with what you have at the time...lol...in any case using a 1/4" ID suction line was a bad idea, it was much to small. 1/2" ID hose is a much better match for the oil flow velocity. The PRV might still be the problem....I have it set much much below what it was set at and designed for. I have two more things to test which will tell me if the valve body is bypassing or if the PRV is acting flakey at the low setting.

Been pondering this... I was looking at Test #4 and you said it was delivering 3000 cc/min at 220 PSI, in neutral. I don't understand that with the valve in neutral the system is loaded so much. I'd expect a much lower back pressure (maybe 10-30 PSI) - appears there is a restriction going back to tank that is too high. Do you have a filter in the return line? If so, have you tried removing it for testing? Vented tank? Could vent be restricted? Did you get a schematic of the valve? Might look at it to see if anything unusual or unexpected in the guts of it.

Ken

Sorry for the confusion in test number 4 ......what I did was to remove the return hose from the valve body to tank and only use the small 5/32" OD tubing instead......this forced all the flow in the return to pass through the small tube, which did two things....first it told me the total output volume of the pump, because all the oil from the pump had to return to tank through this small line, and it also proved that the small line could handle the required flow volume needed for one cylinder. Hope that makes sense.....

I'm sure many of you are getting tired of reading about the 1:1 hydraulics I'm trying to use in this build, but now that I started down this road it needs to continue until I can get it to work properly or this whole idea will be a complete waste of time and money. So if this ideas tanks, at least the rest of you will know to avoid making the same mistake and just go buy the proper system for this type of application. (That would just be to easy....lol)

Did one last test to see what might be happening to the "mysterious vanishing flow".....turns out Ken and Mario called it !!! (Ken mention this right from the start) The full scale PRV on this valve body does not like to work very well at low pressure, and I know why it appeared to be working at the beginning.....the original small return line was restricting the flow which created the illusion of proper function....lol....long story.

This time I blocked off one port on one spool valve, connected both feed lines from the other port to the ball valve and directed all the flow into the second clear container, ran the pump....and all the flow was going through the return line back to the main black container, which is normal. Next opened the control valve attached to the ball valve, when fully open all the flow was going to the second clear container and there was no flow in the return line going to the main tank (black container), which is good, no problem with the spools. While doing this I slowly closed the ball valve....and finally got the answer to the problem...there was flow in the main return line at about 200-220 psi, should not have seen any flow until the PRV setting of 275 psi was reached. In the tests before this one the only time I would see the pressure hit the 275 psi was when the cylinders would reach the end of their travel, only then would pressure spike to 275 and then drop to about 200-220...lol...the problem was right in front of me all the time, but dumb dumb just didn't catch on...yikes..:cop:

Don't feel bad about not seeing the issue sooner KP. Feel happy your still making progress and can move forward with the system you've created. :)

It's all about accuracy within a range. looking at the valve your using I'm guessing it's rated at probably 3,500 - 4,000psi? Maybe 2,500?
When trying to maintain 275 what's not working properly is the cracking pressure of the relief. It's supposed to hold closed and stay closed and then snap open when opening pressure is reached. When it's turned way down out of that " proper cracking pressure" range it opens slightly and slowly and in essence becomes a flow control and not a pressure relief if you know what I mean.
Question is, how to remedy? I wonder if a lower rated relief valve is available?
I think best thing would be to make your own relief externally or purchase a RC hydraulics type relief? The 4200 relief comes to mind but I know there are much better versions out there that might work ?

Can't help but feel a bit like a dumb dumb and really disappointed in myself for missing the obvious problem...... but sometimes when you are trying to trouble shoot a problem you take for granted that one component is working properly.....wrong....I was convinced that the PRV wasn't the issue....not...so off we go on a wild goose chase....lol...the school of hard knocks did however teach me a fair amount more on hydraulics than what I knew at the beginning, so it's all good!!(just wish I wasn't such a slow learner...lol)

The stock PRV setting on the valve body is from 1500-3750 psi. I simply installed a smaller spring, and it worked...or so I thought...lol....you are right about it always bypassing like a flow control never really totally closing or holding pressure!! I will most likely have to make a stand alone PRV before the valve body, would really like a piloted version but can't seem to figure out how to make one, a simple poppet style will have to do. Should I use a ball bearing and seat or a tappered pin and seat...???

Cooper

01-16-2016, 11:48 PM

I may not be the best advise but I would think a tapered pin and seat would be better. Assuming you have the capabilities to hold tolerances. And I'm sure you do ;). I would think the hard part would be getting the right spring. I've been wanting to make one myself and have just assumed a taper would snap and flow better than a round bearing surface. ill be following how you make out so my learning curve might not end up with more parts for the recycling bin. :). Appriciate you posting your progress good or bad.

This goes beyond my knowledge and experience with hydraulics. I troubleshoot and fix existing systems made by people much smarter than me, never designed or thought about making a relief but based on hyd principals the ideal relief would be a needle type seat.
Just like cylinder diameter and surface area effects the amount of power generated , so does the smaller the surface area of a relief needle valve effects the strength and sensitivity of a relief and better for that cracking pressure type operation.
Like I say.... Beyond my pay grade but that's how I see it:). Nice thing is you already know flow rates and the amount your dealing with and I wonder if there's a formula out there that would tell you port size and needle dimensions to get what your looking for?:confused:

Hmmmm, i might be able to get you a pilot relief valve that runs at about 350psi come to think of it! I'll let you know next week.

Tapered pin and seat sound good but would not be my choice for a PRV. I deal with tapers every day at my real job. We make our tapers down to .000015" tolerance on diameter and .000015" tolerance on taper. These tight tolerances are used for a pressure fit of the male and female tapers. The parts are not held together by any bolt or screw just the mating of the 2 tapers under any type of pressure. A PRV using a tapered pin may lock up on you if the 2 surfaces were close to a perfect match on tapers. It takes a lot of force to get 2 matching tapers apart. Some times they don't have to be that actual close to make a very secure fit. This is in the medical field for replacement hips, shoulders, and knees.

I would use a ball bearing rather than make a tapered pin.

Just my thoughts and opinion.

Took the stock PRV apart only to find it was not seating properly....go figure...so I recut the seat angle and what do ya know....it works better now, who would have thought it was bad right from new??!!:cop:

With one control being used it operates at 240 PSI , the PRV will open around 325 PSI and hold steady at about 275 PSI. When both controls are used the pressure drops to about 150 PSI which is a bit strange, may just be how things work with an open center valve. The flow and cycle time on the cylinders is almost right on the money now.....still could be faster I think....next will be to increase the pump RPM and get a bit more flow, but first I need to make a bit bigger drive pulley on the motor. Thankfully this is finally starting to work like it should....

With the controls in neutral (no load) the pump turns at 1700 RPM and drops to about 1400 RPM with a load. The motor draws 20 amps under load and 12 amps when the controls are in neutral....yikes...really going to need the two 14AH batteries!! LOL

Here is a short test video......still think it is too slow!! But much better than what it was before:)

Looking good KP. When I built my Volvo I bought a Mustang convertible top pump with cylinders for $80. I thought I had found the ultimate poor mans hydro pump!lol Anyway, it fit in the machine perfect but I did a quick test and it drew 13amps just firing up with no load. In my machine there is only enough space for one 12ah battery so I had to ditch it and change to a smaller pump and motor. At least you have the space for more batteries! If you can increase your pump rpm to run all cylinders at once at a happy speed you will be able to dial in the TX mixing on the pump and valves so that it speeds up or down depending on the movements. This should help with run time and make the machine easier to run.

Looking good! I think the speed is pretty darn close. Although everything is new and tight and maybe a little more speed would be nice in the long run, you have to keep in mind this is a big machine and more about sheer power than being nimble and quick. Also looks more realistic when moving slower and smooth compared to those machines you see with super fast and jerky motions.
Definitely moving forward on the hydraulics part. With the proper gear reduction on the pump drive hopefully you can kill 2 birds with one stone and get that flow you want and increase run time. :)

Lil Giants

01-26-2016, 04:20 PM

I would say your speed is pretty good there, how fast it needs to be will depend on your ability to control the model while operating 4-5 functions simultaneously. ;)

My 850 only reaches max pressure when cyl(s) reach end of stroke or the force needed is beyond the cyl's capacity. At an idle the press is less than 1/3 & arm moving through the air is 1/2 - 2/3.

01-27-2016, 11:06 PM

I think the speed is about right. The PC1800's we have at work are slow compared to the PC2000's and PC1200's. Generally the bigger the machine the more power and less speed.

I would personally rather have the machine a little bit slower but fully controllable than fast, twitchy and hard to control.

I have been following your thread with interest . I am using roughly the same size gear as you . I think from memory you are using a 2.2cc pump and an open centre spool valve. I am using a 1.6cc pump as i only have 4 cyls on 1/10 scale .

I was interested to see how you went with the open center valve as i was going to use the same , but i read they are not good for uses other than hydraulic motors- mainly due to sealing around center . I liked the fact the pressure is not present unless using a control , but can not get my head around how you get pressure on one vale while the other 2 are -open to tank? -

I noticed you get some creep on the other cyls ,but maybe that is because you have removed the detents and it is hard to find the exact center ?

Strangely after watching your video i think i may go with closed centre spools and use the throttle mixing in the radio to increase pump rpm when a channel is used ( ie -- theoretical numbers --%50 rpm for main boom=2x cyls , %20 for the arm and %20 for the bucket ) . Which would also turn the pump off when no hydraulics are used . Maybe this is common , but i can not find videos where they do this -maybe there is a reason and i will find out through trial and error or maybe some on on here could explain is this is a bad idea and save me time ?

I am looking forward to seeing you progress with this model as you already look like it will be very well made ,, all the best .:)

Yes the pump I'm using is about 2.2cc/rev. The open center valve body can be hard to figure out how the open center works without actually being able to mess around with one....but it does work!! LOL
I changed this valve body to a closed center by simply installing a "closed center plug" which is on the right hand side in the photo. So if you use an open center valve be sure it can be changed to a closed center when the proper "plug" is installed, this will give you the option to go either way, closed or open. The valve body and the matching center plug is from princess auto.

Yes you did see the cylinders creep...lol.... and yes it is because I didn't get the controls centered , the control return springs are removed

Using the valve with a closed center didn't really improve anything, only slightly more responsive due to the constant high pressure, but the pump motor is always under load draining the batterys even when the controls are in neutral, I'm hoping to try and avoid using an ESC on the pump motor so I will most likely run this with the open center...time will tell.

The 1/4" shaft under the servo tray will be the pivot point of the spring loaded belt tensioner for the small vbelt pump drive. Throwing around the idea of adding a sevo to the tensioner shaft and being able to disengage the belt, the motor would continue to turn but the pump would stop, decreasing the amp draw and adding a little bit of battery time....really trying to avoid using an ESC on the pump motor if possible....just a thought

I think if you're able to properly time your swing to your hydraulic speed, your cylinders will always be in motion lowering the amp draw from the pump, and an esc on the pump would help with that too varying pump rpm with the number of valves activated at any given time.

This is an interesting picture... you've turned a horizontal bandsaw into a vertical with cutting table, could I see more pics of how you jigged that up?

Thanks guys!!!!

Now that I have a better idea of where things are going to be located I could finally mount the valve body in place and then fab the hard line from the pump, ended up switching sides with the pump and motor, works better with the pump on the same side as the tank.....go figure...lol

Now that the valve is mounted I could finish the work on getting the controls connected to the servos, the 6-32 threaded rod seems to be rigid enough to move the valve controls....time will tell. Hopefully this set up will work, how well it works remains to be seen, having the servos mounted more directly to the spools would be better...less chance of free play from servo to spools. This whole hydraulic system is not typical for an RC but hey I'm going to try it out and see what happens...LOL

Thanks again guys!!! Glad you like my attempt at building this model....trying to keep this as simple and functional as possible. Hopefully it all works!! :D:D

Mounted the hydraulic/servo frame to the floor, so while it was apart I also added some access holes to get at the motor mount cap screws....having this frame attached to the floor has really increased to the rigidity....thankfully...the 1/4" aluminum floor needs all the help it can get.

So.....after experimenting a while with a spring loaded belt tensioner I finally decided to build a simple adjustable tensioner that moves in a slot on one side beside the pump.....took this apart again and then had a total brain fart
and marked the angle of the slot the wrong way...hate it when that happens!!:mad::eek: YIKES !!! So then proceeded to take a light cut, the whole time not noticing the painfully obvious mistake and well the pictures tell the story....lol....just as I got to the end of the first light cut I noticed that the slot was angled toward the pump mount studs....to late now..."NICE REAL NICE" Wasn't sure if I should laugh or cry...lol...gave this thing it's first nasty build scar!! After cutting the slot at the proper angle the tensioner should work a bit better now!! ;)

Superb work Sir! I feel I have learned a ton from you and a couple others on this build I appreciate you all posting for all us noob's. What do I search on Princess auto site to find those cylinders if you don't mind sharing.

Thanks!! Glad you are learning something from this build, I'm learning from it too!! LOL I would say most of us on here have things to learn and if we share what we learn (good or bad) then hopefully we can all learn a thing or two from each other. This forum is loaded with some very talented people building models far more complex and interesting than what I build so be sure and check out all the older builds as well!!

The air cylinders I'm trying are not from Princess Auto , the pump and valve are but the cylinders are from Automation Direct

Needed to see what this thing will look like, a 2D cad file just doesn't cut it sometimes, so this is a simple way to get a 3D visual before making it in metal. Somethings just didn't look right (scale) on the cad drawings like the black hood and side grill...seems to big, not sure. And the cab on this machine is huge!!! :D:D

PrimeRigg

04-26-2016, 10:27 PM

I agree with dadsgarage, the cab looks larger than it should. And the main body seems a bit taller as well. This might just be an optical illusion because of the colors you used for the paper mockup. Your wooden template seems well proportioned to the diagram you supplied on page one of this thread. So, I am going to assume that your paper template is based on the wooden model dimensions and draw the conclusion that everything is correct.

My advise is, never use yellow paper as your building materials, save it for final paint.

Here you go Joe, a few pics with the plywood stick/boom/bucket,it does look a little better seeing it all together...LOL

I did changed the size of the cab slightly and I think it looks better now...still a big cab....the full scale cab is almost 7 feet long, just over 5 feet wide and just under 7 feet tall and it's weight is almost 1 ton....yikes....

Really trying to get this model to look like the real deal as much as possible without getting to detailed but some details and dimensions just have to be right in order to get it to look right and do this big machine justice, but building something with limited info is a challenge. Even though I usually try and build a simple versions of the real machine most times trying to keep a build simple gets complicated...go figure...:)

That looks really good with a more complete looking machine. I think scale and the smaller details look pretty spot on. After adding handrails and maybe a somewhat realistic interior the size of the machine will really show itself. Killer job as always!

Looks good!! I know what ya mean with some things need to be spot on and some other things can be skewed a bit. I always just try and figure what your eyes are drawn to , bucket, cab, size relationships. This is working out to be a monster!! What is the max height of something you can load? That soda can really showed the size of this bad boy!!

Thanks RW!!

The max loading height of the full scale is about 31ft which would be 31" at 1/12 scale , because I don't have the exact cylinder stroke as the full scale it will only have between 27-29 inches, still need to finalize the cylinder mount locations so that might change a bit yet. If I increase lift height I loose in digging depth which should be about 10", i think I will sacrifice a little of the depth and try get more height, one inch either way should be ok. Can't see this thing digging down much or ever loading something 31" tall, unless I want to load a wheelbarrow with it....don't think a single 777 truck will keep up! :D

Hi guys, we got evacuated Tues afternoon. We are all safe and are staying with family in St Albert.
It was a horrific event for an entire city, and it still isn't over yet!! It is an experience that 80,000 plus people had to deal with. Everyone has endured this event in different ways, many have lost everything, some have not lost anything....yet...unclear on the next few days. The next few days will be long for us all, the "not knowing" is painful!! I can't see anyone being allowed back there for a number of weeks, and even when we go back we won't know what to expect until we see it all first hand. I have lived up there for over 20 years and it will be heart wrenching for myself and everyone else returning there for the first time to see what is gone.
Special thanks to all the many people that have been so helpful and supportive during this, we truly live in an outstanding country.

We didn't have any type of damage to our house other than the smell of smoke for the first few days back, even the power was on most of the time because everything in our fridge and freezer was OK as well.

I did manage to spend some time on building the hydraulic tank, it is 2" x 5" x 14" long and if filled to the top would hold about 2200cc, hoping to have just under 2000cc in the tank when in use.

Still need to make a few changes to the intank strainer but this will the general idea
(#60 stainless steel mesh , really wanted to use #100 but couldn't get any)

I welded a baffle plate inside the tank, the idea is to help push air bubbles up and away from the suction side, not sure if it will be of any help in such a small tank but thoght I would try it anyway....

Nice to see your able to carry on with the build! She's really looking like a mean machine coming together.
Tank features are very cool and love it. One thing that came to mind though, it's hard to tell in the pics but how thick is the tank walls? Just wondering about cooling factor..... Then again, such a large surface area heat retention shouldn't be a problem?

Making some awsome progress ..this machine is build to last and some great features with the tank as well ...to darn bad you are so far away ..Btw sure glad you made it though that devastating fire ..so many people lost everything ..im sure you knew many ..my heart goes out to them

Oh, like that tank, looks so good and with all those featchers built in it must be a winner.
If/when I will have to rebuild mine, some of your solutions will be copied :)

Thanks Dan!!

Good to hear everything turned out okay for you. Glad your able to get back to work on this. Very nice work!!!

Thanks!! It sure is nice being able to continue working on this project...there for a while I wasn't sure if that was ever going to happen!!

Thanks!! The tank filter/screen design was really just a fluke, was originally thinking of just soldering the screen to the outside of the copper tube but luckily found some brass tubing that fit really snug against the screen when inside the copper tubing, sometimes luck is just as good as skills!! LOL

The tank wall is 3/16" thick, the reasons for it being that thick is to be able to cut pipe threads directly into the tank wall....the original design had some threaded holes on the side of the tank as well but ended up changing things around a bit and just decided to use the same thick wall square tubing....already had it so hey...got to use what you got!! Hopefully heat retention doesn't create any problems, I think it would take a long time to heat everything up enough to cause any troubles...hopefully! Lol

Very glad that you did not suffer any big damage - and prayers for those that lost everything. Your hydraulic tank has more features than some I've seen on real machines and the shovel is looking really great.

Ken

Me too!!! We do know a number of people who lost everything!! We are very fortunate to still have a home etc!!!
The features in this little tank might be a bit overkill but hey...why not!!

Thanks Ken!!

The fire has impacted everyone up here, some more than others.....some people are rebuilding and some are not. I know a number of people who never lost anything in the fire but have still decided to leave town...only time will tell how much this affected us all.

Got started building the boom...finally...started by laying out the sides and cutting them in the band saw.

After drilling the pivot holes I bolted on a couple of heavy washers (turned on the lathe) that had the proper diameter/ radius and then used the belt sander to grind the radius on the ends of both plates, the thick washers act as a guide and or stop point while grinding the rads by hand.

Really trying to hide any welds, so most of this will be welded on the inside. Only the longer top section will end up being plug welded from the outside.....so I milled a small shoulder on the edges of all three outer plates, doing this also leaves a small lip on all the edges much like the real deal.
The small slots on the front of the bottom plate are to allow the front pivot/hyd. mount plates to be welded on the inside, as well as locate them... (hopefully this will all make more sense later....lol....just need to make a few more parts of the puzzle)

This is what was used to layout the lines etc.....

Spray on the layout bluing, scribe the lines, when you are done the part spray on the remover and wipe it off with a rag. Here are two brands that make both the layout fluid and remover, I find that the Osborn brand is better but both work well. Hope this helps...

How heavy do you suppose the arms/bucket will be built from steel?

DADSGARAGE

11-26-2016, 01:36 PM

Thanks Joe, I have most of the parts made for the boom and the total weight is 14lbs, once everything is in place etc I'm planning on milling away some of the unneeded material thickness in places where no support is needed to help bring the weight down. The full scale boom is 26000lbs, 1/12 scale is 15lbs, so if nothing else on this build is to scale at least the weight should be close!! LOL

The full scale weight for the boom, arm and bucket is 39.4 tons (78800lbs) 1/12 scale would be about 45lbs. The total weight of the full scale machine is about 400,000 lbs' 1/12 scale would be about 231lbs.

Funny you should mention that some things I do you don't understand at first....your not alone, I also don't understand some of the things I do...lol...I don't know about any of you other scratch builders but for me it seems that you get an idea in your brain and just have to go with it, good or bad, only to ask yourself after it is finished...why did I do it that way??....when there was a better/easier way to end up with the same end results...lol...I guess it's always easier to figure out when you have something to actually hold in your hands and or see compared to just a thought in your head, but hey I guess that's just part of the fun and challenge of a scratch build...

Also made the small lifting lugs...funny how the small parts take so much time to make, hopefully the end result and appearance will be worth all the time.

You're right. Small details do take time but add so much to the overall build. Those lifting eyes are perfect. Now you and some of the crane guys can actually field assemble your excavator, after being hauled in by 7 or 8 lowboys. That would be a hobby show on its own!

Used a small sanding disc on a die grinder and a guide with the proper radius to finish the keepers after rough cutting them on the bandsaw, not the most accurate way to do it, but it does work fairly well.

Thanks Joe!! CNC is the way to go, much cleaner build and 10-20 time faster!! This making parts manually is painfully slow!!

Almost finished all the parts of the puzzle for the boom......hopefully I can get this "mess" all welded together, inline and without shrinking the pivot bore size, time will tell.

With all the fine machinist work you've done to date KP, I think you should now build your own cylinders to compliment the model. :D :p

Thanks Joe...yes I have considered making cylinders....but at this point I think I will use the cheap air cylinders and just focus on getting this build functional. Once this model is actually finished I really can't see these air cylinders lasting very long, so I can see building some cylinders for this model happening in the future. But for now I really have to spend my time on getting it finished and hopefully functional!?😃

That boom looked so big , until I saw the pic of it attached. Really puts perspective on how monstrous this model is!!! Not saying it's is small but it looks small once it's mounted, in comparison to the base!! I think I see one of those hydraulic lifts in your future!! To work on this monster!! You are really doing a great job on the parts, nice clean lines, hidden welds, that lip on the box of the boom is really going to pay off in looks. Appreciate all the pics also, very much enjoy the building process and sharing of how you are doing the cuts!! Even if you would have cut them with a program it still is a lot of hard work!! Definately going to pay off in the end and show it off too!! You got me thinking about something to load the haul truck with, I was think big loader but having something heavy with the payout force like this may be better suited for me. ,,,, have truck need loader,, lol!!!

Lol....yup it looks big by itself but not so much when it's on the machine...there is one thing about face shovels that always seems strange... the fact that even the full scale machines don't seem to be to scale...lol...the boom and stick seem to small for the size of the buckets!!
Glad you like all the pics I posted...sometimes I wonder if anyone is really interested in seeing all the boring details of how this is being made, but hopefully it will help give ideas to others !!

There are no boring details in build threads! :)

Always interesting to see how people work things out. Some (if not most) of the build threads on here are way above my skill level, which makes it even more interesting. Already had some nice "so that's how they do that" moments while spending time on this forum.

So thank you very much for posting the pictures/explanation. :)

I seem to be having trouble getting on here......and staying logged in.....very strange?? I keep getting logged off without actually logging out, and then can't seem to get back on. Same result on my phone and computer....let's see if this works for more than one try.....

Ok.....so I have started working on this build again......put grease in the gearboxes, threaded and welded the sprocket hubs and machined flats on the drive axles etc
