Whats' the minimum bend radius for 1/8 and 3/16" polycarbonate sheet?


Bending hot or cold?

I've seen references that suggest using a sheet metal brake which is an
almost negligable radius (and I assume a cold bend)

Hot you should be able to form it at will.


I don't think lexan lends itself to hot bends, however I have made
several three panel winshields in a sheet metal brake. I bends
beautifully, however don't ever spill gasoline on it, especially if it
is stressed or it will craze and shatter almost immediately.
