  • From ehow, one of AB's partner sites: Cut Plexiglass With a Power Saw Step 1 Use a ruler or measuring tape to determine the thickness of the plexiglass you want to cut. Thinner plastic tends to chip more, so you will need a saw blade with more teeth to reduce the risk of chipping. General Saw company's catalog of plastic saw blades can help you choose a blade (see Resources below). Step 2 Choose your saw blades based on the thickness and hardness of the plexiglass. You may need two or more different blades to alternate during use, since harder acrylics chip more than softer materials. Acrylics that are softer are more likely to melt, and require saw blades with fewer teeth in order to cut effectively. Step 3 Attach the blade you have chosen to your saw. A table saw or circular saw work best for plexiglass. The saw you decide to use is a matter of personal preference, or whichever you happen to own. Step 4 Put on goggles before operating the saw. It is important to protect your eyes from plastic chips that may fly. Step 5 Place your plexiglass sheet on the work area and begin to saw. If you experience a lot of chipping, you may need to use a blade with more teeth, and if you get smearing, you should increase the number of teeth on the blade. It may take a few tries to determine which blade (or combination of blades) work best. Step 6 Use a fine grain piece of sandpaper to smooth any rough edges on your cut piece of plexiglass. Tips & Warnings: Maintain your saw to ensure the best performance. Sharpen blades as soon as they seem dull. Clean the saw when needed and keep sharp blades out of reach of children. Plexiglass shards can cut you just as bad as metal or glass, so be sure to sweep your working space clean of all debris after working and wear tough work shoes at all times. http://www.ehow.com/how_2056832_cut-plexiglass.html
  • I use a saber saw, a table saw or a mitre saw, depending on application. Sometime with thin plexi and stright lines, i score and break.
  • I've used a table saw with a fine toothed blade. My husband is happy using a circular saw but he's good with one. I've also used a scroll saw to cut out intricate pieces.
  • Depends on the thickness and what you are using it for. Thick plexiglass may be best cut on a table saw or radial saw, depending on the size. Cutting shapes you might be better off using a saber saw, band saw, jig saw, or coping saw. There are various other power saws you can use, so pick the best choice for the job. Any time you use a power saw, though, you want to use a sharp blade and more like a finer toothed 'finishing' blade than a ripping blade. This gives you a cleaner edge along the cut. For thinner pieces of plexiglass that you are straight cutting for, say, window pane replacement, you would use a plexiglass scoring tool and a straight edge. Score the plexiglass where you want it to break, line the plexiglas up with the scored side facing up and along the edge of a table, and sharply bend the plexiglass down to snap it along the scored line. There are also some tools which use a hot wire to make cuts in the plexiglass by melting your way through.
