Dragline Crawler Build

Wow, those tracks look great! Are you going to put any rollers on top of the side frames to hold the track sag up?

Jared,

Thanks! I was waiting on the 2-56 screws so I could assemble a complete set and start checking the pitch and freedom of operation. I do plan on 6 lower and 2 top rollers. In fact, I think they should help keep the pads and tumblers in line for better operation. Been working on the tension system brackets and mount.

Working on upper and lower rollers today

Rollers and pins, rollers and pins...and I'm only about halfway done

Need to make 5 more of these and then match drill and tap the holes. And that is only the bottom, five each side

I think I will/can do 2 each on the top.



Another one of those things that I think, "well, that shouldn't take too long" and then I spend all day doing it
