Using the Fixed-Post Grinding Machine for Rough Grinding an 11 .Feb 16, 2014 . Gordon Waite sets up his fixed-post mirror grinding machine to begin rough grinding on an 11" f/4.3 telescope mirror. He uses a grinding tool made from dental plaster and steel pieces to speed up grinding. Gordon shows the setup for spin grinding at high speeds and with added weights to get the job done.fixed grinding machine,Machine Mirror MakingHere's Jeff fixed-post grinding on a 24” using Greg's machine.. So, there are a few machine styles out there. In our shop we use fixed-post grinding and polishing, then parabolizing with an Elgin style system.
