The M-o-M is a marvellous machine due to its simplicity and yet refined design. It is extremely flexible accommodating mirror sizes from 4 inch up to 20 inch (with slight modifications) and can be used for all three steps necessary in producing a mirror. That is you can use it to grind, polish and figure your optics.

Telescope Formulas and Design Comparator This page lists various telescope related formulas and it calculates telescope & mirror parameters for you. It is primarily oriented to the Newtonian reflecting telescope, which is what most first time telescope makers build, although many sections of it are applicable to other types of telescopes.

Grinding the secondary is just like grinding any other optic except in minature. I ground the secondary with the workstand and worked the tool on top just like I would grind a larger mirror. This optic is small enough that a lens grinding machine could work well.

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.

I started this thread to record my building progress of a new mirror grinding and polishing machine. This machine will be capable of handling mirror sizes up to 22". I have decided that 22" is the absolute maximum otherwise becomes too cumbersome to move around. I have won 2 x 1/3 horse power single phase electric motors on eBay, at $45 each.

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

After fine grinding, the mirror was rough polished on the fixed-post machine using a pitch polisher. The Ronchigrams in the photo area show the progress of the mirror from rough polishing through figuring. After the mirror is finished up, I use a diamond stylus to engrave my name, the focal length and the date on the back of the optic.
