Years ago, I built a disk sander using a motor I harvested from a washing machine. It's got it's own stand, on/off switch etc. It worked pretty well, but has been relegated to a corner of the shop since I got my oscillating belt sander.

I'm thinking about turning it into a dedicated lathe tool sharper by fitting it with a CBN wheel and my wolverine jig. It's 1725 RPM, so that's good, but I'm wondering if 1/6th HP will cut it. It always did pretty well as a sander and I figure the CBN wheel will also act like a flywheel. The time it might take to spin up isn't a concern for me, at least not yet. Curious to know if I'm overlooking something.

I have a 1/2 horse on mine and it struggles to start the CBN wheel moving. However once it gets going it runs great. I think if you gave the wheel a spin by hand before flipping the on switch it would probably work although if you tried to take a big cut or a left the tool on there for a longer period of time it would probably slow down.
