Re: 1/16 Oliver Dozer Conversion

I got a reply back from the help desk of the motor controller. My gut reaction tells me that it doesn't really put out the amps to the RX like they claim. But, it also doesn't seem to like the...

Re: SCALE LOADS

Looks really nice, was it expensive with the shipping? All the little detail is the hard part and also makes the look.

Got the new undercarriage all assembled. Now I need to figure out how to attach the hood and operator/seat. Then, how to store and retain the lipo, RX and motor controller. If all goes well, this...

Dozer Refit

Well, I'm on a mission from God to try and do a motor refit on the little Oliver dozer in time for Brownsville. Just got started on it yesterday so that gives me about 10 days or so to work on it.

Re: Ny-Lint Mobile Dragline Conversion

Friz,

Ya, you are right. I just haven't decided exactly how I want to do it yet. I'll probably let it wear fora few hours and see how it goes. The shaft will be easy to replace and I might also...

Re: Ny-Lint Mobile Dragline Conversion

Well, that only took about a weeks worth of full time working in the shop! But, it is pretty much finished and I think it will perform much better now. Ball bearings on the new drive tumblers...

Re: Ny-Lint Mobile Dragline Conversion

Steve,

Thanks for the tips! I was able to lightly clamp the assembly in the drill vise and then tighten the screws. This seems to allow it to stay flat enough to satisfy me for now.

Here is a...

Re: Ny-Lint Mobile Dragline Conversion

I'll try that. I might try and put a slight cone shape on the face ends of the spacers so only the outer diameter touches the bar stock. I guess I could set the spacers on the surface plate and try...

Re: Ny-Lint Mobile Dragline Conversion

I am reworking the frame rails for my crawler, but, it has a twist in it. Here is a short video that should explain what I mean.

Re: Ny-Lint Mobile Dragline Conversion

Made some progress this weekend. Here is the new prototype drive tumbler just about ready to go back together for a test. I will make a new wider one with wider side flanges, once I see how it...

Re: Ny-Lint Mobile Dragline Conversion

Tom,

They wrap around pretty good, I am hopeful that they might work better than the old style I tried first.

I know what you mean about the width. I may be wrong, but to fit/clear the lugs on...

Re: Ny-Lint Mobile Dragline Conversion

Jared,

Ya, you are spot on! Problem is, to do them any wider I will have to move the frame rail out and that changes everything else down there. So for testing, I'm going with it as is. If I...

Re: Ny-Lint Mobile Dragline Conversion

Progress on the crawler update. I machined a few new drive dogs for track pads and made a new main and center idler wheel. I need at least four more small idlers then I can test the new design.

Re: DAF torpedo front truck and front steer truck

Very interesting!

About the resin, is it a single component? Not two parts with hardener? How long or how slow does it finally get hard to sanding stage?

Thanks for all the info!

Re: Caterpillar 990H - 1:14.5

Are the tires cast in one part or two? Two, then glued together?

Looks very nice!

Re: Ny-Lint Mobile Dragline Conversion

Tom, thanks for the picture. Do you know what brand or age the machine is? I'm curious about when or why they decide to use various style lugs and drive tumblers.

Re: Dozer Upgrade

Thanks Bo, lots of stuff to look at both places! Might be fun to try and build a gear box with right angle or worm gears.

I see on the second site they list the worm gears as right or left. Does...
