While laying fiberglass, and letting it harden, I have been working on the rear drive hub. It’s terribly hard to explain the many difficulties in designing it, as well as building it, but oh well, here goes. First, it needs to bolt to the rear wheel, then go inside the rear frame tube, yet still be supported by a bearing, have a sprocket that can come off, and the whole thing needs to have the 5/8 rear axle bolt go through it, yet it can’t touch that axle, cause the hub spins, the axle doesn’t. The sprocket is welded to a collar which slides onto the 1″ pipe of the left side of the hub. I had to have everything on a 3/4 axle to weld them together, so it will all clear the 5/8 axle later. The pictures can do the talking I guess.
