so im sitting in class yesterday thinkin of making my front square shaft. ive talked to a few people and the pieces i have to make mine seem to have a lot of sloppiness. i have a read of the sheet metal idea, weldin a bead or two down the length of the tube. now recalling a conversation with a friend who is a crane mechanic about the outriggers he mentioned wear pads. so i was thinkin of ways to incorporate something like that. so what about think sheets of plastic to take up some of the slope? figure 4 strips the length of the reciever tubing possibly glued in or just let sit? thoughts, comments, suggestions?
