Did you use it edge on, or flat down? Where can you get these things? I was just looking today at some bad marks on mine and thinking I may have to get it replaced.

And what drill speed please?
Edge on, think I got mine from Machine Mart years ago but I would imagine Screwfix would also do them. Mine came in a kit with a variety of wheels, a mandril to mount them on and a couple of bars of polishing compound. I originally bought them for polishing the aluminium cam covers on my e-type...
My drill says 2200 rpm.
