I have a project where I need to cut some lexan that's about 1/8th inch thick. What's the best way to cut it? Using a saw? I thought about using heat somehow to cut it, because I have to cut a circle out of it, but I don't know how to rig up something like that. I have a little dremmel saw that's just too weak to cut it. Whenever I put any kind of pressure on the plastic from the saw, the saw stops. What do you recommend? Thanks.
