[You have to heat it up with something, a butane torch or a hot gun. I would practice with some cheap scrap pieces first though. You can get it too hot and it will bubble. And you have to be pretty good at it to get the bends straight.]
[Bending acrylic is simple. Simply apply heat (oven or propane torch) to the acrylic and then bend to the shape you want. It work better if you can just heat the section you want to bend. If you use a propane torch do not leave flame in one place to long or it will melt and bubble the acrylic.]
[Call Allied Plastics they are in dallas they carry the plex and you can have them bend it for you i think the charge a $1 a bend, but not sure on the cost]
