I would like opinions please. I am thinking I would like a buffer for the pens I make, but I am cheap. Here is my plan. I have an old Kenmore motor out of a sewing machine. It has s foot pedal to vary the speed with. I'm thinking of mounting it on a board that I can clamp to a table, put a 3" or 4" buffing wheel on it to buff pens. Just cost the price of the wheel, I have a 1/2" mandrel for it. Think it would be worth the trouble to set up?
