I don't know what your application looks like, but we used to run
humongous sideboards on Dominators and SRP's and the like.
Did a billion of them.
If you are using "Lexan" about a half inch wide or so, with about a 45 on each end,
just put it in your needle nose pliers, and bend it..
It bends great. Just push on it as close to your pliers as you can,
and you will get a decent sharp bend right there.
