I'd like to have several Mac Mops (see an example of one at Klingspor's site: http://www.woodworkingshop.com/cgi-b...adItem=MM00518 ). Specifically, the manufacturer Klingspor states:
They are best used on a motor with at least a 3/4" diameter spindle and operate at between 1100 rpm and 3000 rpm.
I'm looking around at buffers and motors on stands that might have variable speeds and am not finding much. It looks like motor speeds are pretty much fixed, 1725 and 3450, and that variability is an expensive option. It would be interesting to be able to try various speed between 1100 and 3000. I'm looking for a motor that has 3/4" spindles on both side, akin to a buffer, sitting upon a stand (like the Grizzley buffer/grinder stand at http://www.grizzly.com/products/Stan...-Grinder/H7834) would be the solution. The issue I've yet to investigate is a motor and pulley (several pulley choices) aspect.

Has anyone specified and assembled a flap sander unit that would be just like a buffer, but with a slower motor within the manufacturer's RPM limits using Mac Mops?

I especially like the idea of the mop being out in the open as a buffer stand affords so you can hold a piece against the spinning mop from all sorts of angles.

I think I had a Mac Mop back in the early 90s running on a Shop Smith at it accomplished the task of easing edges marvelously.
