Cutting glass tubs (1 Viewer)

Just wondering what you guys with glass use or would use to cut the tub. I'm gonna put some "you know what" flares on the back, and know I need to cut a little.

I used a pneumatic cut-off wheel to do mine. Basically its a die grinder with a 3" cut-off wheel and a shield. It cut through fiberglass with no problems and left a smooth edge. You do have to be careful not to let the wheel catch and go where you don't want it to.

Just a little trick for you. Get some 3/4 inch masking tape and use it to tape out your desired wheel opening line. Use the cutoff wheel as Mark said to rough it out to @ 1/8 inch of your tape line. Finish the last bit off with 36 grit on a hand sanding block (maximum control if your not used to this) or use a small grinder or air file with 36 on it if you have and are comfortable with them.

Home Depot sells jig saw blades that are coated with carbide grit, with a variable speed saw and some patience they work great on fiberglass.
