Dragline Crawler Build

And now, for something completely different...

Here is my first prototype drive tumbler! Still working out the details.



Don't even have the second side formed because I didn't leave enough center hub to hold onto. Back to the lathe...

Finally got one tumbler done both sides. I am waiting on hardware so I can assemble an entire unit. Need to have it nearly complete so I can tell what I need to do to the drive dog ears on the pads and the tumbler flanges.

I am pretty sure I am going to need to put a bevel on both, just not sure how much on each. I sure it will be more trial and lots of errors.
