According to Steve B :
How do professionals cut plexiglass? I am going to need to cut some, as
well as rout some of the edges to make them fit into slots.

Would I be better cutting these on a table saw with a special blade, or
using a router blade that has say a narrow width? Maybe even taking more
than one cut, and using a fence as a guide.

I'm going to Google on this, just wanted to know if anyone did this sort of
thing. It has to be a quality finished cut.

Both plexiglass and polycarbonate will cut quite cleanly with normal
woodworking tools (tablesaws with crosscut blades, routers etc). _If_
the plastic is thick enough - eg: at _least_ 1/4", and you move things
along at a proper speed and don't stop.

Thinner stuff should probably be scored and snapped.

As for "quality finished cut" - well, that depends on what you mean. If
you want optically decent, you'll have to polish it.
