Okay. I got my hands on a nice little hunk of tefloon. The only problem is that it is a bar about 3/8 x 1 x 6 inches, and it is pretty inflexible. for the az bearing, would it be best to try to cut a smaller piece off of that and curve it to the round bearing, or should I leave it flat, and only have the 2 points of contact? I imagine that leaving it flat might give me too little friction, and any little nudge of the scope will move it way too much...and how to make a curved surface out of a flat bar? Thanks for the advice.
