Re: Cutting Lexan
I have had good results using Irwin Marathon blades cutting 1/4" thick acrylic on a table saw. I usually tape both sides with masking tape to help with the chipping problem. In fact, I have had good results cutting just about everything with those Irwin Marathon blades including Lexan and aluminum. We cut about a zillion feet of aluminum this season with one on my 12" miter saw. We also cut a lot of thin (<~1/16" - 1/8") Lexan with a jig/scroll saw and a plain old 7 1/4" skill saw with a plywood blade. You can cut Lexan with just about anything in my experience. At competition, the inspectors wanted us to shield a pinch point/sprocket on our robot and all we had was a small piece of 1/16" Lexan and pair of scissors. The scissors cut it to shape just fine and a couple of minutes and a couple of zip ties later we breezed through inspection.
