pic: Lexan + Heatgun =

[Jay H 237]

I've done a similar thing to the edges of my model train layout to protect the rolling stock in case of a derailment so it doesn't end up on the floor. I used 1/4" Lexan and heated it with a heat gun to match the contour of the edge of the layout. I have a variable temp (200-1200 degree) Milwaukee heat gun. I started at a lower heat and held it about 6" from the piece and slowly tried to bent it. I'm guessing I bent it around 350 degrees with the heat gun several inches from the Lexan. The amount you hold the heat gun over the piece will depend on the thickness of the material, the temp you're got it set at, and how far away you are from the piece. It's best to try it on a scrap piece first. Just remember some plastics are combustable.
