Re: Logging & Construction Equipment
 

Lou, you're making great progress. Can't believe how much you've accomplished since last Sat. If you keep that up it'll be moving dirt before Christmas. Well maybe not, I got the bad news our goodies are out of stock and won't be shipped till the 20th Dec. Anyhow great work and keep the pictures coming.
Rob

Re: Logging & Construction Equipment
 

Wow! Nice work Lou! You have been busy, that's for sure. I am amazed at the pieces you have been able to make with such a small cnc. Are you pushing to have this done for the show in CR? Do you know a solid date for that yet?

Re: Logging & Construction Equipment
 

Excellent job!!!...WOW!!...I know how much time and work it takes me to make parts for my simple builds so I can appreciate and admire the work you have in this build...
This forum is loaded with many very skilled and talented people which is a great help for those of us who may be lacking in skills and new to the hobby... Keep up the great work !!!

Re: Logging & Construction Equipment
 

Almost ready for paint now eh?

Re: Logging & Construction Equipment
 

Close Rob may have to use it for snow removal ..lol ..thanks for the update on those parts ..we will definalely have to get together for some xmas drinks

Reg im on a roll...Im waitint for parts for work so I have my head burried in Cad / Cam ..Been fun though ..havent heard anything yet about the show yet but soon im sure

Thanks .Yeh it does take some plannig .thanks for sharing your great ideas as well...so far I only had a few screw ups..The neck is very full up front with not alot of room..two servos and the drive system..Its working but not perfectly ..try and get some drivetrain test video up..

Jerrrett ..not Quite yet..lol..All the details are gona take some time but I am almost ready for hydros ..still a few bugs to work out ..I am not sure if the big 1/4 scale servo is gona be quite strong enough for the atriculation yet after some short testing ..may have to go hydro ..On the plus side that would make more room in the engine compartment

Thanks for looking

Re: Logging & Construction Equipment
 

I did some testing on the drivetrain ..sorry no vids yet but soon ..and had some difficulty with the steering and binding ..I ended up making a bearing block and seems to work much better ..The o-ring drive belt i was using at first was slipping too much and putting too much tension on the whole assembly so i dug in my parts box and foung a nice little tooth belt and cogged pullies..Much better ..Having the front wheel drive makes things way more complicated and wheel tilt as well as having the whole asembly ossilate and steering was a challenge to make work ok ..still not perfect but it does work..

Re: Logging & Construction Equipment
 

Wow Lou, nice progress. I can just imagine that the 6 wheel drive is probably twice as complex than the 4 wheel dive would be to build. Your doing a jam up job on this and your CNC work. Ready to see it work.

I ran Robs blade at ST Louis last year it was blast. Your going to have fun with this.

Re: Logging & Construction Equipment
 

Thank you Joe ..Rolling right along and having fun with this build ..Robs Machine is so impressive ..I can wait to see what your next build is ..I hope you srart something soon
heres a small clipon my facebook page of the gearbox ..yeh it works ..Pretty strong little gear motor for the size ..im impressed

Re: Logging & Construction Equipment
 

Looking good Lou...

Can't wait to see it moving dirt..

Re: Logging & Construction Equipment
 

Very nice work. Can't wait to see it working.

Re: Logging & Construction Equipment
 

Lou
As always when I look at your builds I say to myself I have a ways to go to meet your projects quality. One question I think I see 2-56 hex head bolts, my Pacfic Fastner source ended only 4-40 now where do you get yours

Earl

Re: Logging & Construction Equipment
 

Looking good Lou! Inspirational.

Re: Logging & Construction Equipment
 

Great job Lou. You are raising the bar for the rest of us Island guys for sure. I am looking forward to seeing this at the CR show!

Re: Logging & Construction Equipment
 

Thanks for all the great comments guys

Earl Yes lots of 2/56 on this build ..Micro fasteners and Festener express have them in stock ..a little cheaper at fastener express and I found 2/56 x 14 there as well where micro fasteners doesnt have those ..I really wish the head pattern was a little smaller and more scale on the 4/40 in stainless ..I have seen some in brass at a link for train supplies that Rob sent me ..should give them a try as well ..Rob said his prices were good too .. http://www.americanmodeleng.com/id41.html

Reg did you say Bar ....Im trying to stay away from bars ..lol..Seriously ..Im trying to keep upto you these day ..Your a building machine ..lol..Should be at least functionalby the show in CR

Re: Logging & Construction Equipment
 

T-n-T-Lou-great work on a very complicated model. These look like the toughest to build out of all the construction models. Good job!!

Re: Logging & Construction Equipment
 

Lou
Just thought I would give you this site for 2-56 Hex Head bolts looks like about a quarter of the price of American Model 2-56 SS X 3/8 is $6.10 per 100 http:www.microfastners.com/home.php?cat=576.
Thanks for pointing out sites to look for.

Earl

Re: Logging & Construction Equipment
 

Wow....tracksandtredlou you are where I hope to be when I retire. I hope to have a small network of friends and equipment when I retire to do just what you have done. Very nice Sir and keep posting please!

Michael (ekim)

Re: Logging & Construction Equipment
 

I know they are not exact scale but they do add a bit more to the looks ..I dont see any philips heads on the one to one scales


Thanks Michael ..really apreciate your comments

.

Tom at times I think I bit of way more then I can chew ..some things are working really well like the table rotation and mold table and others have been a nightmare ..the large servo for the articulation had to be replaced will hydros as the servo wasnt quite strong enough ..the steering had a few bugs in it as well and I messed with the linkage to get it working ok ..Having the front drive is creating a bit more strain but I think I will get these bugs worked out ..

The hydros now that has been a pain in the %$#...Last fall I bought a pump and 3 spool valve off a well know US ebay member ..I am not knocking him because im sure he wasnt aware of the problems with this product at the time. He bought 3 of these units and after emailing him about the problems he said they were all crap ..I thought i was getting a good deal and Paid over $400 for the pump filter and three spool valve ..A leimbach pump would cost that much ..Anyway this unit is pretty much a chinesse knock off of the leimbach ..spools are a touch larger ..The + side they used bearings on the spool cam ..4mm fittings and metal gear servos ..servos are very cheap but seem to be working well.. The pump looks very much like the leimbach as well ..Gears are a bit larger and the unit I quite a bit noisyer then the leimbach ..Buyer beware..The Valve leaked from the moment I hooked it up ..The pump was labouring and drawing way too much current and now leaking out the motor shaft ..I should of sent the whole thing back but It sat for months in the box before i set it up ..grader has been sitting on the shelf for months with a big puddle of oil under it

Well I am trying to recoupe some of this money i have spent of this so I am working out the problems one by one ..first the valve ..I tried replacing the o-rings and found the same thing happened .I made the oring grove wider and doubled up on the oring ..better now but still weeping a little on one spool ..may have damaged the o-ring when i put it back together ..I also found out the servos were bottoming out on the inward stroke..One servo broke the housing during the strain...after closer inspection the plunger was bottoming out and hitting the cap screws ..The cap screws another joke ...They were wrapped with teflon to try and seal.Idiots
Leimbach uses an o-ring on the seet ..I ended up using the valve servo ajustment caps that you remove from the valve .the same thread as the cap screws . I Cut the ends off and used 5x1 mm o-rings on the seat .Should be able to see in the pics ..seals and works way better ..Glued the servo and valves seems to be working ok now ..

Now the #$@%&* ..Pump After inspecting the pump I noticed the the is a extar line off the top of the pump to the tank for the releif valve ..Looking it over I noticed there was no way for the Oil to exit or pass the set screw when the PRV did open ..They were expecting it to bypass through the threads i guess ...NOT ..Idiots ..I just drilled a 1/16 hole through the center of the PRV set screw now the oil can bypass into the tank ..I dont have a guage but im thinking the pump may have creating too much pressure for these vavles ..Now the shaft is leaking on motor side ..Opened that up and the only thing i see is some type of neoprem bushing ..I put 3 layers of walbro carb gasket material under the shaft set screw and that seems to have worked ..time will tell..If I didnt get laid off last month I would be replacing the whole works with a leimbach set up..Live and learn

Re: Logging & Construction Equipment
 

T-n-T-Lou-sounds like you may have gotten burned on the pump system but seems like you solved all the problems. I never worked with hyds. but hearing about all your troubles I am glad I never got into that. Your model works great in the dirt. I especially like how you have accurate speed control. This will be handy when doing complicated tasks. It will be interesting to see what all you can do with this model, such as dig ditches, put slopes on banks, etc. Looks like a fun machine to run. nice work!!

Re: Logging & Construction Equipment
 

Lou, Your grader looks and works great. That is quite a project!

Sorry to hear about your problems with the hydraulic parts..i think i might have some of those hydraulic systems in my shop that a customer left here for a future build..i'll have to compare what i have to the pictures you posted.

Re: Logging & Construction Equipment
 

thank you Tom and scott..To someone without any experience what soever that could mean disaster and out of $400 bucks ..If you see any out there its best to stay clear
Im not out of the woods yet though and hope I can resolve this ..

scott the unit came without the motor ..If it is the same one i really hope you can get it woring as well ..heres a few more pics

Re: Logging & Construction Equipment
 

That is very impressive. It can really dig in and take quite a cut. The driven front axle appeared to be working very well and was making a real difference. Is that about the top speed with the gear motors you are using, or are you just very disciplined. It looked to be just about perfect for grading, I just didnt know if you had some in reserve for a "road gear" if you know what I mean.

I understand not wanting to flame the E-Bay seller if you beleive he was not aware of the poor quality of the hydraulics, but do you mind telling the manufacturer or some other way of identifying these so that others who dont have the same experience and abilities as you dont get burned.

Again, This is an amazing model, Thanks for sharing.

Re: Logging & Construction Equipment
 

Lou, i just looked and sure enough i have that system here.. little triangle clamps on the corners to secure the tank and all.

I re-read through what you posted and i believe that the system i have came form the same source (Shipped from New Jersey).

Re: Logging & Construction Equipment
 

Thanks for the awsome comments ..The Company that made or supplied them is
LESU and make quite a bit of stuff for rc4wd as well

Re: Logging & Construction Equipment
 

Stay away from these

http://www.buychina.com/items/lesu-t...em-utooppsmlno

Re: Logging & Construction Equipment
 

Yep, that is it..i am not blaming the guy that the pump was purchased from either..i just looked at his ebay listings and does not carry any Lesu hydraulic components.

Re: Logging & Construction Equipment
 

Sorry flyingbeagle I forgto the speed question ..I do have a bit more gas at 35 RPM..Would like a bit more but grading will be tricky at any faster speeds .Going to take some getting used to ..Now I need to build some road ..Maybe greg will come to help

Scott when you are ready to do something with it feel free to ask what i did in detail if you need ...oh yes I did trim the cover allen screw for the PRV so I could get a little more adjustment on the set screw

Re: Logging & Construction Equipment
 

I recently Purchased A pair of Boxes off of RCP Reg ..one a pup so i figure i would try to desing a hoist for it ..decided to try out the firgelli cyclinders ..Im using the 50 mm 150 rpm 12 volt ..rated to lift 40 lbs ..Thanks for hooking me up Ian ..I also purchased the remote control with keychain ..this way the pup will be independant ..heres waht i have come up with so far

Re: Logging & Construction Equipment
 

COOL!! Nice design!!!

Re: Logging & Construction Equipment
 

Wow, that actuator is so smooth and quiet, and I think you did a great job on the design of that scissors lift mechanism. In my opinion, it's a nicer way to go than the screw drives. The lifting speed is more constant throughout the range of travel. Screw drives all seem to suffer from the jack rabbit start, and then putter out at the end of the stroke, but this takes care of that problem!

Re: Logging & Construction Equipment
 

Added a little color to the screening plant and modifide the bruder conveyors ..stilll some fine tuning ..post pics later ..heres a vid

Re: Logging & Construction Equipment
 

That looks awesome Lou! I am so excited about the upcoming show! We will have a lot of different things on the go there this year!

Re: Logging & Construction Equipment
 

That's a pretty nice screening set up!! And your post on the dump body actuators changed my planning phase on a dump build I'm doing. I was doing a similar lift but going hydro. After watching your video and looking up the actuators I am now going that route. So much simpler than all that hydraulic parts to find places to hide. Thanks!!
