Title: Plexiglass (sp)
Post by: geneVG on April 21, 2012, 08:40:28 am

I was wondering if I needed to get a different type of blade  to cut plexiglass or can I use the blades I use to cut wood.  If I need a different type of blade what kind do I get.  Thanks

Best advice I can give is talk to FDMike at http://www.mikesworkshop.com/index.htm (http://www.mikesworkshop.com/index.htm) about blades and cut at VERY SLOW speed.

Hi Genevg, don't cut at too fast a speed as the plexiglss can melt and rebond behind the blade. Then you'll have fun!!!.LOL.

 I use regular blades to cut plexiglass, remember to use very slow speed, and keep the paper backing on.  Edward

Yea I don't change to any special blades either. Just slow speed and moderate to slow feed rate..

What if you have a single speed saw?? I think slowing the feed rate the glass would rebond?

Don't worry a lot about the re-bonding as you can go right back through the cut with the same blade and release the bonding.  It's very easy.

I have found that if you put masking tape over the lines to be cut that you don't usually have a problem.  I apply the tape and then draw the lines.
