This page has lots of text, photos and GIFs which show how to use optical machines used for making telescope mirrors. I tried to do it but didn't see the moving diagrams. The GIFs are important because they show what the polishing tool will do. Mirror polishing is of course done with a slurry of cerium oxide. If AOO can handle this type of file I thought I would take some text out to shorten it for my own use. The link to the page is below. Also included is a non moving screenshot
