Hi Brian,
Acrylic and Plexiglas are one in the same. Given the thickness of 1.5
inches I can't see any financial benefit to prototyping with a low
grade Plexiglas which no doubt is going to be very expensive regardless
of the lower grade. If it is machining that you want to play with, you
might try calling around to see if you can get a small remnant. If it
is fit-up that you want to play with, how about using a 1.5 inch
Styrofoam panel from Home Depot or Lowes?

Greg, I have already machined my viewports
and they are just waiting for me to get the acrylic lenses to fit in.
I was thinking that I could purchase some regular plexieglass (1 1/2"
thick) and machine those so I could play around with how everything is
going to fit together. Can you tell me if the machining properties are
much different between the cast acrylic and regular "low grade"
plexieglass? I imagine that the cast acrylic would be a denser
material so it may machine and polish much differently. Thanks,
