Fixed-post machine grinding is where the mirror is on a turntable rotating around 20 PRM [speeds vary], and a 75% tool is on top. They are already curve-generated. The tool is hanging over the mirror by 1/6 the diameter of the tool, or about 1/8 diameter of the mirror, and is fixed in this position.
Mirror-O-Matic grinding machine. When I decided in 2009 after a ten-year break to get into mirror making again, it quickly became clear to me that I would need to construct machine, as hand grinding big mirrors is not something very beneficial for the hands of a musician.
My Mirror Grinding Machine. For a long time I've wanted to build a machine for grinding telescope mirrors. Dennis Rech's M-o-M designs finally inspired me to just get up and do it. Over the years, I'd been collecting motors, gear boxes, pulleys, etc.
The Design . I began by measuring the sizes of what I already had, a 1/3 hp 1750 rpm electric motor and a 25:1 geared speed reducer. Then I took a rough cut at the MoM-20 H-frame and placed the motor and gear box on it. Lining up the pulleys, drilling holes for the mounting bolts and making sure the belts would clear everything drove the design

The mirror machine came to me as a result of astronomical horse-trading, swapping a large GEM mount and a 8" Newtonian OTA for the machine as it was and a start kit consisting of two 6" blanks and the grit, rouge and pitch to manufacture a mirror. The grinding machine had been built to the design of the mirror-o-matic design of Dennis Rech ...
After six months of grinding a rough concave surface, the exacting and tedious job of figuring and polishing the surface of the mirror began in the autumn of 1905. Because the shape of the mirror had to be perfect to within a few millionths of an inch across its five-foot surface, special care was required to insure the mirror’s accuracy.

Mar 16, 2015· Page 1 of 5 - Making a Mirror grinding & Polishing machine - posted in ATM, Optics and DIY Forum: Hello, I am on the half of the way to make a mirror grinding machine inspired by original M-O-M design. I made the pulley arrangement such a way that, both the turn table & eccentric spins at 50 RPM fixed. I wont go for making mirror bigger that 10.5 (or max 12).
In addition, a great deal of money will be saved: a finished 24" scope will set you back $7,000; grinding your own mirror and building the mount yourself will cost you $2,000. Amateurs have made mirrors up to 41" by hand. A grinding machine relieves the labor, but is not necessary. A 24" is the largest you can comfortably do solo.
Rough grinding is complete for the 12.5 inch honeycomb-back telescope mirror blank. The rough grinding went pretty quickly and painlessly this time. I only have maybe 12 hours of actual work in the mirror so far. It's hard to believe, but the rough grinding has removed over a pound of glass. The mirror now weighs in at only only 8 pounds 15 ounces.
