I'm looking at putting together a polisher similar to those in the DIY section. I have exactly zero experience with laps. I've seen some posts mentioning RPMs and grit stages, but not sure what to aim forI've got a motor laying around that's 1/5hp and 825 rpm. How would that work for direct drive?

A lap and a polisher are two different animals! if you want to use grit that RPM is way too fast. This is a polisher, it only uses cerium oxide on it. the lap is a similar machine and I only use 120 grit on it. In Between the two I use a bull wheel sander using 100 gt, 220 gt, and 400grit.

Thanks for the clarification. What I'm looking at are the designs that use the diamond pads for slab polishing

I had an ameritec 8 inch one that used diamond pads, worked fairly well but I was not using it so I sold it to a member on here, It had a variable speed control. you might look at them and get an idea of what you ant to build.
