^This reply should be considered first before you dive into the electrical part of the project.^ The size of the motor, rpm needed, etc. is highly dependent on the application. What exactly are you trying to achieve here? There are small buffing wheels and big buffing wheels, the extreme ends of the buffing wheel size spectrum shouldn't even be on the same tool let alone the same motor.
With that said, you have received some sound advice on the electrical side. If you are considering a purchase of a router speed control, why not purchase a cheap tool to run the appropriate size buffing wheel for your application? Harbor Freight may be your best friend in this case.
VT, this first one is an experiment. I got this juicer for $10.00 at a garage sale. If this works, I will then probably make a heavier duty unit -- for heavier sanding and lapping -- with a router as the motor. My materials need to generally be run with water, for cooling, as one of my plastics will warp with too much heat.
Below is a photo of a benchtop wet lapping machine that I'm trying to replicate or approximate. These are used a lot in the jewelry and rock industry. That sucker costs $550.00. Heck, I can make one for less than $100. I'm really having a lot of fun experimenting and also saving beaucoup bucks.
