elementcollector1 Posted January 24, 2012 Share Posted January 24, 2012 I've heard that when fiberglass is cut with regular saws, etc., it tends to crack and chip. Is there another way to get a better cut on this? I have a fairly large sheet of Plaskolite that I'd like to cut into a variety of pieces. Link to comment Share on other sites More sharing options...

If you have an angle grinder handy you could use a diamond tile cutting blade and put masking tape both sides of the cutting line first. This what one or boat builders I've just read do. Whatever you do use the masking tape first. Link to comment Share on other sites More sharing options...

Xittenn Posted January 24, 2012 Share Posted January 24, 2012 (edited) Cutting it with a blade does a number of things depending on a number of factors. If you want a super clean finish you will have to rough it first using this method and then use any number of methods to finish it. I've cut and machined a number of materials like Acrylic Sheets and also Solid Surface. A fine grit and a little drop of oil, followed by some buffing, should finish a surface like this quick. There are routing bits specifically for machining plastics. I would suggest trying a plasma cutter if it is available to you.

Externet Posted January 25, 2012 Share Posted January 25, 2012 Thin abrasive wheels do work the best in my experience. Link to comment Share on other sites More sharing options...
