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.
It is not a robot, but just a pattern of polishing. For big aperture though, spinning a large mirror and moving a large polisher might be too much work. That is why the mirror lab spun caste their glass to avoid hogging, and then had a robot go around grinding and polishing the high spots. Or maybe they spun ground it.

The I.A.U. named asteroid 17823 Bartels discovered 1998 by J.M.Roe in recognition for my contributions to amateur astronomy. Making is the Key to Knowing. A telescope mirror is arguably the most accurate surface made by human or machine. Amazingly you can grind a mirror by hand and make a telescope with simple hand tools.
Grinding Machine for Large Telescope Mirrors I designed and built a grinding machine for mirrors up to 42 inches [1.1m] in diameter. By slipping on and off a couple of belts, the machine can quickly be reconfigured for spinning work or for stroking work.
There are many reasons for grinding your own mirror. Either you want a unusual size, or focal length, or to satisfy your curiosity, or to have the "pride of achievement" by fabricating something as precise as a telescope mirror.

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.
Mirror Grinding Machine. 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. Most of them came from industrial junk yards.

You may notice that many commercial telescope advertisements proclaim they use "Hand Figured Optics" - in fact this is one of the best and least expensive ways to get an accurate surface on a mirror - most machines just can't hold the tolerances necessary, and any good telescope optic, including the mirror you could make in your kitchen, should be hand figured.
