Dragline Crawler Build

Looking good jim-that is a nice beefy press you made. I agree with jared on the rollers, just a slight chamfer on the edges should help. I say you need some clearance between tumblers, rollers, etc.. This allows for dirt not jamming the parts. 9W may know something about this.

Not too much "visible" progress today but I have actually gotten a bunch done. I wasn't happy with the brass pins linking the pads so I decided to try taping 2-56 holes in the outside tabs and drilled a clearance hole on the inside tabs. The only 2-56 screws I had are shown in the picture. They don't look too bad although a bit big looking I think. I ordered some button head and some plain set screws. I will try those and decide which way to go.



If I had made this decision earlier i think I would have milled the pads such that there was a shoulder in the outside to let the head of the screw sit flush with the outside edge of the pad.
