I've been reading through the back posts on this and there seems to be a few varying opinions.
I have to make several cuts in 3/16" Plexiglas, some as long as 48". I don't mind trying the score and crack on the shorter cuts, but I think I'll go with the TS for the longer cuts. It seems that most people (?) prefer to use a plywood blade. But I'm wondering about the blade height? I would think that a higher blade would reduce chipping, but increase the likelihood of melting (more friction). Any experiences?
