I had a bear of a time cutting some plexiglass without cracking it.



It was 3/16 inch thick.



Using a very fine toothed sabre saw did not work.



I tried scoring it with a sheet rock knife.



I finally made some progress using a hack saw and going REAL slow.



Any tips ?

120 teeth per 12 inch blade. Cut on the backside with the blade cuting
through about one half inch. That side would be facing out the backside
will be chipped slightly. Let the blade cut the material. Sand or buff out
the chipped side if desired.

Last time I cut 1/4" Plexiglas I was using 28 carbide teeth on a 10" blade.
That's about 1 tooth/inch. With the top of the blade ~1/2" above the work
there was no white melted crud or any chips missing. Used a paint scraper
to smooth off the cut edge. I have no idea what RPM my tablesaw runs at.
