Re: [ATM] Edging a Blank

Michael,
I think the problem with your bungie approach is that the edge is
smoothed out but any out of round condition may not be resolved.  Once
the glass mates to the tiles you end up taking glass off the all around
the edge not just the high spots.

The jig Thomas referred to I think solves this because the tiles are in
a fixed in radius.  Once the tiles mate to the glass along a certain
degree of arc the blank should be both smooth and round.
