John,

Based upon you comments, it would seem that all that I have been using is
Plexiglas, some cast, some extruded. And not Lexan. The 'no fear of
chipping' statement confirms that. I have learned to work within its
limitations and have accumulated the bits, blades and buffers to assist me. 
However, is Lexan a better product? How is it priced compared to Plexi?  Can
it be cut on a band saw (Plexi melts, congeals and hardens to quickly).

Gary,

Basically, Lexan is easy to cut, there's no fear of chipping,
or breaking.  However Plexiglas (Lucite) is brittle and takes
care in cutting and drilling.  Plexiglas
and lucite are both brand names for methyl methacrylate.
(not sure if I spelled that correctly).  Lexan is a brand name
for polycarbonate.
