Bronze Brushes Revisited

I like Donald Kinnaman's bronze brush idea ("Tech Tips/ aw ยป32), but I've found the brushes more effective when mounted on an arm tliat is free to move. This takes carc of the brush wearing down as well as any uncvcn-ness in the wheel. A torsion or tension spring could be substituted for the weights.

I was helping my dad make a picture frame and found it difficult to hold
