Actually, today I gave it a shot. I'm working on an old bass I got from a pawn shop, and had removed the f'board from the neck. I wasnt having much luck getting the old glue off with sand paper, so I gave the surform a shot for kicks. Actually, it worked pretty good! I think the "cheese grater" blade was dull or something, cause it cleaned off all the old glue in a few passes, but didnt touch the wood at all. I checked, no wood shaveings came off, they were only glue. Not bad, eh?
