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.

One machine is designed for grinding concave mirrors of small focal length. The other machine, a much larger piece to implement, grinds mirrors of large focal lengths. Though Leonardo da Vinci creates sketches of mirror grinding, one crucial and logical question to ask is whether he used such mirrors in his artwork or drawing.

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.

Before starting machine grinding and polishing, one should at least read several books on mirror making. Most of these books will be about hand work, but knowledge of calculating and measuring a sagitta , pouring pitch laps, building tile tools, and most importantly reading and interpreting the Ronchi and Foucault tests are extremely important.

I had an idle mirror grinding machine (a modified MOM 20), so I volunteered to grind and polish his blanks and check for strain using the cross-polarized light test. Soon, three plate glass blanks arrived, two 10 inch and one 7.5 inch. They looked pretty bad. They showed a lot of strain where Horace had taken a belt sander to them.

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.
