darn plexi glass........ahhhgggg...

[brokentine]

answer may be simple but not for me.  How in the world do you cut thick plexiglass.  Tried roto zip, saw, and utility knife witch got me no where.  Need help. 

[itsatrophy]

I use a band saw, slow and easy should work fine

[nate]

i use my dremel with a cut-off wheel.

[Oakcreek]

Bandsaw. as said go slow bot not so slow the plexi can regel around the blade.

[jonny]

table saw for straight cuts

[M.T.]

a variable speed jigsaw.  Make sure the plexi is on top of a hard surface, and make sure when you are cutting, that your sawblade is real close to that surface, that way, the glass wont want to jump up and down on you. With a variable speed, you can figure out real quick what speed to cut it at.

I like using a dremel with a cut-off wheel like Nate or a jig saw like M.T.. Just make sure that it is a blade with finer cutting teeth- not a wood blade, and safety glasses are a must. Nothing worse tha that cut-off wheel shattering and whipping past your eye at 170mph.

band saw is the best I've used. Just cut some up at my other job(windows on machines) noone else could do it without breaking or shattering the edge.

jig saw with a metal or plastic blade, router with carbade bit,  circular saw 40 tooth blade.  there are 2 things that go wrong when cutting plexiglass it will chip some times large and violent and it can also melt and gum everything up.  chipping is caused from teeth of your blade being too big or rpms too low, and melting is from the opposite too small teeth moving too fast. If using a circular saw always set the depth just through the material 2 1/2 in of blade under your pice is bad, it changes the angle of approach of the blades teeth and increases risk of chipping or cracking it. variable speed jig saw works great, with a finer plastic or metal blade, just make sure you put a few layers of masking tape on the deck, so the plexi is not scratched (same with circular saw)

Table saw.  Just make sure that you go slow and that you are holding down as close to the cut as possible, keeping it from being able to bounce about.  Sometimes running a strip or two of masking tape where the cut is to be helps keep it from splintering.

We cut some with a fine tooth blade.  one trick was to reverse the blade.  Try it.

[mark c]

score both sides with a masonary blade snap off take sanding dic sooth out use polishing compound to make clear again  i used t carve parts for clocks that way  mark c

[bill@hogheaven]

We have 2 hardware stores in town that have machines designed just t cut plexi glass. Perfect cut everytime. You might see if you can find one in your neighborhood.

I to score the glass, only I do it on one side. This takes a little practice to get it right but when you figure it out it is the quickest and most simple. I use a tourch to turn the edge clear again. Just barely heat the edge and feather it out it will come clear with little effort.
