Has anyone tried heat forming polycarbonate sheet, like Lexan as opposed to Plexiglass? I need to put some curve into a simple windshield, so it maintains a certain curve; more of an ellipse than an arc. I need it to maintain that curve by itself. Simply bending it will just result in an arc and won't do. Lexan seems to be very reluctant to bend from heat, I did some trials using a heat gun. Very unpredictable too. Does Plexiglass form fairly easy using simple methods? Has anyone tried it without resorting to ovens? I only need two simple bends really, no compound curves, but this stuff is not co-operating.
