Simple jigs to assist in polishing the roller bearing contact washers used in the SkyWatcher AZ-GTi tracking telescope mount. There are three different sizes used. 

I started with a long sanding of 600 mesh wet/dry sandpaper on a piece of picture frame glass, then to 800, 1000, & 2000. Switching to Micro-Mesh cusioned polishing papers (not the polishing pads) throuh 6 grits ending with 12,000. Finished with a buff with Semichrome Polish. This might be overkill for this low end mount but I had it apart to fix another part so why not.
