what a pain in the *, finally settled on a jigsaw, used razorblades to score and try and snap, just busted it up. tried circular saw with blade backwards, it shattered it also. got 18 tooth blade for jigsaw and ran it on less half speed, if got to fast it would chip and shatter, slow about third power was good it was just much more than 3-4 foot and motor heated up bad, as plastic melted as much as cut, and when you stopped it would harden on blade and not cut till it cooled off and you chipped it off blade.
It has been almost a week to get about a dozen peices ranging from foot square to maybe two foot by three foot, got a bunch of used plexiglass the mall was throwing away where the wife works, they were about 3x7 peices that had been temporary vendors in center of aisles. free is free but it was a pain in the *....

Have seen guys put thinner sheets in a plywood sandwich with good success. Never tried it personally tho.
And fiery auto crashes
Some will die in hot pursuit
While sifting through my ashes
Some will fall in love with life
And drink it from a fountain
That is pouring like an avalanche
Coming down the mountain
Score (actually more of a groove) the Plex and then 'snap' it.
Works like a charm.
Sometimes good old fashioned hand tools work best.

I was fortunate to get a 'Plexiglass scoring tool' from the local plastics company 30 some years ago.

Learned how to cut it in shop class almost 60 years ago, however can't remember what I did. Guess forgetting isn't part of learning.
Do remember it was easy to polish using a polishing wheel. Made a knife out of red plexiglass but don't remember how I cut it. Maybe it was blue? Bet it was a hacksaw. The plexiglass had peal off paper that could be drawn on. Think it was two sided, but again, don't remember.
Fast enough to get a good cut and with enough tooth set to make clearance for the "chips".
I've cut it with jigsaws, TS and bandsaw.
Don't use zero clearance inserts. I ruined a good blade when the chips built up between the blade and the insert and blade got red hot.
Coarse enough blade to clear the chips, but fine enough to keep at least a couple in the material.
Don't be afraid of it. It cuts very much like plywood -- and like plywood if it's too thin be very careful.
There's a bunch to choose from on amazon. Do it centers and hardware stores got em.
