Re: Plexi-windshield
Plexi seems to get exponentially harder to bend as thickness increases, especially over 1/4". .... That may be a part of why the estimate was soooooo high....
Acrylics in general are not very thermally conductive, which makes it difficult to heat the entire thickness enough to bend it smoothly, without getting the surface regions too hot and causing bubbles from outgassing.
Bending full thickness 1/2" sheet properly, takes some high dollar equipment.
I'd be looking at something in nominally 3/8" polycarbonate for the best in strength, toughness, and formability.
