    Default Building a Mirror rotator for grinding and polishing



    I am not looking to build a full grinding/polishing machone, just something to make the task of carrying out those tasks a little easier by rotating mirrors up to 12" in diameter. The roatating disk the mirrors will rest on will be about 13-14" in diameter. I am looking for advice on the rpm suitable for this job or more properly the range of rpms suitable as I would like to be able to vary the speed in order to assist with providing a random element in the process. Does anyone have any suggestions please?

    I have used a full polishing machine. It had variable width and length but no variation to the spindle speed. If you are pushing glass by hand, you can't beat that for random variation. If you are set on doing this, I'd recommend a range from 0.5-10 RPM.

    Thanks Joe, I reckon I can achieve that range by a combination of multiple pulleys and voltage control of motor speed.
