Cutting Plexiglass

[Elbow]

Anyone know any good ways to cut plexiglass without shattering it? I am making a new back window for my car and need to cut it a tad shorter.

Scissors

It shatters.

ummmm.....i have no clue. Now I want to know what its cut with.....

[Elbow]

I may try a dremel tool lol. Luckily I need a lot cut so it only shatters the area I am cutting. So if I mess up the part I need is ok. Anymore ideas?

[jhadleyh]

i actually think the dremel will work well i cant really think of anything

sorry simmon i know im not being any help

[Elbow]

Yeah I will try the dremel, I think it cracks from the pressure of scissors and stuff.

Dremel with a cut off wheel, then sandpaper.

make sure to buy a shit ton of cuttin wheels

If you have access to a bandsaw thats what you need to use. A jig saw with a good blade may do the job, and a dremel may also work. But bandsaw is the numero 1 choice. One of my best friends family make motorcycle windshields and thats what they use.

shouldn't need too many, plexiglass isn't very hard so shouldnt eat through wheels too bad.

The wheels are made of hopes and dreams. They seem to explode a brief moment after contacting anything.

Yeah, should be alot thinner than thick plastic. However I've only used the bigger wheels in a air ziz wheel. The dremel wheels may be weaker.

when i made a sub box once where i used plexy glass and i cut it with a skill saw but u have to turn the blade backwards so its not such a rough cut :goodjob:

Dude, come on guys. Use carbide tipped blades on it. I would not use a skil saw or circular saw. Too powerfull it would chip pretty bad. Jigsaw with a carbide blade at a slow speed should work pretty good. Or if you have access to a belt sander, use that. Plex is basically plastic.

Try taping it all up with packing tape, might help from shattering.

dremmel with a cutoff wheel. done it several times

If you haven't done it yet, and it's a straight line you need, snap it. Get a straight edge (metal, preferably) and run a blade down it a few million times lol. Don't put a lot of pressure on it, just enough to make a groove on the plexi. Then, flip it over, put the straight edge on the line, put some pressure on it (I usually use my knee), and pull up against the straightedge. The groove will act as a "starter" for you, and the plexi will snap in a clean straight line.
