I think the gearboxes would have too much drag, and the only ones I have are about 30:1 and another that's about 100:1.

I swear that at the same RPM the lower KV motor had a higher voltage out.

This is going to be a pretty small unit about 16" tall and about 12" in diameter. Just for testing too see what I can do just with what I have laying around.

Keep the ideas going!
I'm really curious about the small sheaves and belts you speak of. I've been toying with the idea of a belt drive rather than a traditional spur/pinion. Have any links or pics?
