I recently picked up a Discovery 17.5" Truss dob and I'd like to mount a pair of encoders on it to use with a Sky Comander XP4. The azimuth looks easy enough since it already has a pivot bolt drilled for an encoder. I'll just have to watch the clearance so the mirror box doesn't hit the encoder. I think I'll have to make or order another part to hold the altitude encoder though. The alt bearing has a half round shaped recess where the encoder would fit. I'm guessing I'll have to find the right size bushing to to fit the recess and the encoder shaft and tap it for a set screw to hold the encoder shaft in place then attach the bushing to the alt bearing (perfectly centered, of course). I already have the plastic arm to hold the alt. encoder housing in place. Am I on the right track with this ? A couple pictures of alt. encoder installations would help.
