I don't have a belt sander, but I do have two scroll saws. Maybe somebody would trade me a belt sander for a scroll saw. Anyway, I'm gonna give it another try.
I have this Ryobi sander
http://www.ryobitools.com/catalog/po...enchtop/BD4600 and it works pretty well for balsa and plywood
It was about $100 at Home Depot
