I got to remove a few inches to fit in a window. It's a big piece too, almost 4 feet and I have to cut off 2 inches the fill length. How do I cut plexiglass?

My friend GB used to build video game cabinets and he used a carbide toothed blade on his table saw to cut Plexiglas.
TDD
I have cut plexi with a electric saw with the blade on backwards.
How do I open a web browser, get to a search site like google and come up with some clever search string like "cut plexiglass"?
Maybe the nine year old across the street can help.
Jigsaw,hacksaw,handsaw,tin snips,........
Table saw, sharp carbide 80 tooth blade. Dozens of posts on this topic in this NG. Check the archives. Or simply ask the techs at a plastics supply house, via Yellow Pages.

I wish I'd had the Famous Usenet Multitool back when I had to cut some lucite panels.

What thickness, the thinner stuff cracks easily with a saw if you let it move or catch on the blade, My Ace hardware uses a glass cutter table, they score and snap, use a sharp fine tooth blade on whatever you use and go slow.
A RotoZip or equivalent works well. Use a guide to make a straight cut. My son used my RotoZip to cut 1 foot square panels that were about
5/16" thick. It made nice clean cuts.snipped-for-privacy@myplace.com wrote the following:
They make a hand tool to cut plexiglas. It's like a carpet knife but works like a glass cutter. You use it with a straightedge. Just scratch deeply a few times along the straightedge, then snap the plastic.
I used to cut/machine a lot of plexi where I used to work. A band saw is best. At home, I'd use a jig saw with a coarse blade. Leave the protective paper on till after cutting. Bee's wax or kerosene make good cutting lubes. If using a jig saw, clamp on some sorta straight edge to hold a straight line. DO NOT slow down or stall during the cut, as the plexi will heat up and begin to melt. If you must stop, back out of the cut immediately. HTH

So again with the unhelpful snarkiness.
Look, pal, it's a *home repair newsgroup*. A place where people come to ask questions about, oh, I don't know, HOME REPAIR???
Next time just STFU.
One of those small plastic letter openers.
Same way as you do glass. In fact, they make a tool specifically for scribing the plexiglas to snap it off. Saws, etc will leave you with nothing but a melted plastic mess on the plex and blade both - don't even bother with any other method. I've done it many times - scribe, snap, Done.
HTH,

5/16" was NOT plexiglas.
Finally, someone who knows what he's talking about amongst all these idiots and guessers.
why not?
nevermind. I get it. It doesn't COME in that thickness. I never knew that.
Correct! Most full-service hardware stores have a glass-cutter that also "scores" plex. The scribe is something like a lathe cutting-tool (only it comes to a point).
