> Most power tools don't work very well on Plexiglas.

	In my experience, one very good way to put a nice sharp clean edge
on plexy is with a milling machine or lathe run at high speed.  In either
case, a very sharp carbide cutter helps.  I've never tried it, but I would
guess a conventional home workshop router would work just as well, or
possibly even one of those cute little dremel tools.

	As somebody else already pointed out, flame polishing is a good
quick way to get the very last bits done.  You basicly just sweep a flame
across the edge once or twice.  Getting the proper motion might take a
little practice.  Around here, the guy who runs the shop uses a hydrogen
flame for this because it's clean, but he's probably just being paranoid
(and it's readily available in the shop).  At home, I would imagine a
well-adjusted propane flame would work just as well.
