You might want to search the web for mirror grinding machines. There's several websites that have been done that have homemade grinders on them and some have used motors like what you have. The need for speed control is a bit overrated as you generally build the machine for a particular size machine and it's a lot cheaper to use different sized pulleys for speed control than using a speed controller. Sorry that I don't have any urls for the machines but they popped up very quickly when I did a search several months ago. BTW, there's an article in one of the recent articles in ATMJ (another thing to go look for as it's a nice magazine for the telescope maker).
