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.

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.

Looks like I'll have to borrow the school's table router. Thanks for the help!

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.

Use a fast helix bit for the cleanest cut, preferably with a downward spiral.

Thin abrasive wheels do work the best in my experience.
