RE: [ATM] Edging a Blank

["Robert Turner" <rbturner@charter.net>]

Michael,

This is just an idea I thought about and have not tried or even know if is
feasable. I considered rigging up a spring held arm on the machine. Just
some tiles glued to a piece of straight wood. Mount one end so that it can
pivot and the other hold it with a spring to the edge of the glass.

Let see... Maybe some ascii art time...
