Mirror Grinding Machine

If you don't have a gear box, you should stick with the M-o-M power head design. In the configuration shown, the reducer shaft output is 50 rpm, the eccentric rpm is 11, and the turntable rpm is 67. This is typical for grinding and polishing. For figuring, I have another set of pulleys that spin the eccentric at 25 rpm and the turntable at 11 rpm.
