Since my laser has a non-standard bed size (12" x 20", 300 x 500 mm), I was wondering what the best way to rough-cut acrylic would be. The way they cut it at Lowe's is nice (big frame-type glass cutter), but the cheapest one of those I can find online is still a couple hundred dollars. I completely suck at making a straight line with the handheld-type glass cutters, and to be honest, I think glass cutters in general take too much effort, especially on 1/4" acrylic. I was think about using my table saw, but I have read that you need a special blade so that you don't chip the edges. Since I'm just rough-cutting, chipped edges wouldn't be the end of the world, but it reduces the amount of usable material I would get out of a sheet.
How do you you all rough-cut acrylic, or do you all have lasers capable of handling standard sized sheets?
