Pete, what do you get out of this? (Don't take that as cynical or sarcastic...I'm really just curious about it.)
Further training on getting the hang of it? Personal satisfaction for taking something that was essentially garbage and turning it into something useful? The joy of helping others? Building some rough numbers as to the time it takes to do one so that you can accurately judge what it would take to make a hobby business at it?
I'm curious, because there's a part of me that's thought about doing something similar with refinishing 51 caps.
(And no, don't start sending me your 51 caps!)
