Possibly a table saw. Make the first cut VERY light, then continue a little at a time. Remove any flash before taking the next cuts.

.
Never, under any circumstances, combine a sleeping pill and a laxative on the same night.

HI Conch29

I would suggest you use the jig saw,,,the table may not be the safe way for you if you have not used it b/4..

I would suggest putting some masking tape on both sides of the Plexiglas and pickup a fine tooth blade,one that's for metal should do the trick..

test cut some scrap b/4 you make the real cut...to get the feel of it..

How big a piece and how thick is it? small thin stuff can be scribed and snapped kind of like glass if you only need straight cuts. Jigsaw works too, but if you don't have the feed rate right you either can gum up the blade if you go too slow or crack it if you feed too fast.

There are special router bits designed for cuiting plexiglass and other plastics. They are designated as O-flute. As far as I know they are available only as straight bits but come in a variety of diameters.

Hi Conch29

You might try the "sandwich" method. Put the plexi between two pieces of thin panelling, fastening them together with double sided tape and then cut away with a small circular saw (jig saw may tend to wander). You did not say how big or how thick this piece is, so helpful info can be varied. Good luck.

Conch,

Is the plexiglass stiff or a bit flexible? If it's a bit flexiable (lexan) and similar in thickness to window glass, it can be cut on a table saw with a ripping blade (~24 tooth). Thicker pieces can also be cut, but you have to be careful with the heat build-up at the cut....shallow cuts and low blade tooth number.

If it's actually old style plexiglass, stiff and brittle, I would use a router with a straight bit and spinning at low speed.

Hi. I went to a glass company to purchase some plexiglass, and they just used a table saw to cut it. I've since done the same at home and it works. I've also used the router and the dremel tool. you have to watch it with the router and dremel tool, because sometimes it just melts instead of cuts, and actually melts back together. Don't forget to use eye and ear protection!!!

Greetings (your name here) and welcome to the forum. At HD you can buy a scribing tool and cut it like glass by making several scribes. in the same place of course, and then break it on the edge of a table.

Only problem I can see if you use the table saw is if it is too big, too flexible and too unweilding to handle. The tape on both sides and the jigsaw would also work.

I guess if you could tell us how big it is and how thick it would help for us to make the best recommendation.
