A number of years ago I picked up some “Rhino” abrasive wheels in
different grits (grana). I think it was in the UK or at a snag
conference. The wheel is a combination of scotchbrite type material
between rows of emory paper. It turns out it works really well on
pewter and some of the folks in Fred Fenster’s Haystack class would
like to find more of them. Does anyone know a source for them?
