I'm working on a 1 1/4 AJ focuser casting I got from the Surplusshed. Somebody really cocked up the machining job, the rack trough was off line. So I opened a pocket around where the shaft goes through, took a piece of the end of a rubber stopper and ground it down and slipped it on a piece of 1/4" bar stock and pinned it so it wouldn't spin on the shaft. The shaft is locked in the casting with washers and cotter pins and has a couple of knobs for electronic equip. on it for now. When I get her all finitoed I'll snap a couple of pretties and post'um.
