First build ,cat D11

[Cooper]

I made a hydraulic tank. The bracket on the bottom is a mount for the 1/2" bar that connects the two tracks together. I still have to add some sort of mounting to the top and a vent. The suction line for the pump is on the bottom and the return lines on top. All are 6mm.

Cooper you must of done this before ..Very impressed with your first Build ..This is awsome ..Thanks for sharing all the awsome pics and very informative discription..Cant wait to see this bad boy rollin

[Cooper]

Thanks!!!

I don't think I'll have the time I wanted this weekend to get a few hours to head down to cabin fever at York. Kind of depends how much rain we get, a lot and I'll have time. But if things aren't too muddy I'll be staying around here. I got one order from premacon today, need the second order to show up soon. Several back to back orders because I don't know what the heck I'm doing with these hydraulic fittings. !!! But some more progress that I'll post up shortly.

Your build is really great and very ingenious the way pieces have been fitted together to save space and provide access - outstanding workmanship! Concerning the aluminum brazing problems: I've used it several times with excellent results; however, on thicker pieces like you are using, allow extra time for all of the metal to reach the melting point of the rod. Early on, I had problems with heavier pieces and learned to wait a bit to be sure everything was up to temp. Even had to use a different torch once in order to get enough BTUs for proper melting. I've always used a stainless steel brush for prep, but never used flux.
Keep up the good work!

Thanks for the info, I know what you mean with the heat. I think a big problem I was having was I had it mounted to a vise and vice grips holding another piece of aluminum for a bit of a jig. I think it was robbing too much of the heat and me not getting it hot enough like you said. I'm using mapp gas but the torch tip is like three little tips, doesn't really localize the heat. Once I get use to this stuff I definitely think it will be a asset in the building options.

Good point about the heat-sinking effect you get with vises and pliers holding the parts. I forgot to mention that I switched to paper-binder spring clips to hold things. They don't soak up much heat, are cheap, available in many sizes, and can be tossed when heat removes all the spring tension from them.

Good luck!

Work on mounting the valve block.

[Cooper]

Found a practical place for the pressure gauge.



There is enough room behind and under the gauge for all the hoses

[Cooper]

With the cab up



And down. You can just see the gauge, but there is lost of room around and above it.

Wow, looking good.

Have some time tonight, I'm going to try and bring her to life. . I don't have the radio for it yet but have one laying around I can use. I ordered one of the new flysky/ turnigy 9 ones. For the money they are great radios. Mixing and assignable channels.

[Cooper]

I know several of you are enjoying all the cool stuff at cabin fever in York and I got stuck home working,,,,,,,,,, lol. Hope you all enjoyed the show, I really wanted to get there.

I found out that I have enough wiggle room on the track links when I remove several shoes to avoid using any master link or connector pins to connect the track ends.




Don't know if it will help anyone else but I've been struggling with an effective acceptable master link , now it's solved.

Ahhhhh, success!!! First test run!!! She is a little slower than I thought but that is probably what scale speed would be. I know I did the math and all that figuring when I was figuring out gearing so as long as it was right then. This should be scale speed. Just seams a bit slow to me.

[Cooper]

After looking into it , speed is about right, I guess I'm just use to rc toys being much much faster,,, and being able to punch it when the cat, wife, dog are in range and getting yelled at. Lol.

[RCP57]

It looks great to me. My wife would not be thrilled about me driving it on the hardwood floor though....

[Claus]

I can't imagine the feeling you felt seeing something you dreamed up and built from nothing functioning so well, great job!

[sparkycuda]

Looks great! Speed is plenty fast - yes, crawlers do their work at a pace much slower than wheeled vehicles and it does seem slow if not used to it. You have much to be proud of. Also, you must have a good relationship with the person attached to the tenns shoes.....floor cleanup going on while you are driving around on it!!!!!!!!

Thanks for the assurance guys!! Well about the running in the house on floors,,, I was already in the dog house about not getting stuff done around house when wife was gone during weekend. So,,, already in trouble might as well have some enjoyment during the moment. . The floor is linoleum. I'm in process of replacing all floors in house.

[Cooper]

This is what those blocks are for, I epoxied neo magnets into the slots. They will hold down the hood and cab.

[Cooper]

Placement of air cleaners and exhaust.


To me they seem a little misplaced but looking at the parts/shop manual that's where they go.


Just some m3 screws holding them.


And to get the parts to stand vertically the best tool was a simple hand file and eyeball
