 I am in the middle of fitting a bracket to hold my autofocuser to my old blue 127mm mak , which is a 3mm thick plate with a 46mm hole that locates over the focuser held in position by the screw in focus adapter but because of the plate thickness when adapter screwed to hold plate I have play in the adapter so I need a washer 42mm  Od and id hole no smaller than 32mm to take the slack up when adapter screwed home anyone know of a washer must be metal or a hard plastic.

If you can’t find a suitable washer this place can make one to your specs. You can specify what OD and ID and thickness you want online.

I’ve used them a couple of times. Delivery is about two weeks.

Yes they are useful. Used one of their “washers” when doing my dual fit (EQ5 & EQ6) Berlebach conversion. Now waiting for a disk to make a puck for the AZ-GTi mount.
