Heh, yep - polishing's definitely approaching an art-form. I'm using my wheels on a slow pillar drill/hand-drill, takes some coordination to keep the workpiece moving whilst remembering to keep its edges out of the way of the on-coming wheel!

Nothing worse than thinking you've ruined a bit of work by polishing in a groove... Well, except maybe when the wheel grabs it off ya and chucks it on the floor.
