I want to use this part (see attachment) to fix an encoder to so my scope can sense directions for a goto system for my Tridob.

The conventional way of attaching the encoders to the ALT/AZ pivot points would not work for my scope as there is none. So this roller would run along the AZ bearings and ground ring instead.
It is a roller with an O ring on its circumference, a .25" hole in the middle and a grub screw to fix the encoder shaft.
Anyone know where I can find one?
Tim.
