I need to bend some 4 foot long (almost), 1/4" thick Lexan sheets. It

Do you have a heat gun? Make a fixture in the shape of your bend, and
blow the heat gun at the lexan on the part that needs to do the bending,
and let it droop as it softens, to conform to your mold/fixture.

A hair dryer isn't hot enough - you need one of those heat guns that
says "CAUTION!!!!! DO NOT USE ON HAIR!!!!!" ;-)

Good Luck!
