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)


You adjust the bend radius on a sheet metal brake with the fingers through
a variety of mechanisms, the simplest being fingers with the appropriate
radius ground on their tips. If you do much sheet metal work on anything
other than HVAC ducting or roofing flashing, bend radius is a big thing.
Basically, anything structural requires attention. Do a google search on
Sheet metal Brake and you will see a number of variations. The following
link:

is for a small cheap brake. It incorporates a single blade or finger, but
it is reversible with a 3/8 inch radiused side. It mentions using the
radiused side for Lexan specifically.

Ok, I stand (sit?) corrected. I was thinking siding brake - not sheet metal
brake - My mistake. Sorry.
