Fletis -

Okay, it's 1/4" thick sheet... If I bend/break it in half in "folding" it,
I'll be in the category of "it was necessary to destroy the village in order
to save it."
Maybe I can rip off a strip.... How far do I have to bend it? Wouldn't even
poly break if I folded a strip of it in half? Any tips appreciated...

Others have offered some good advice.

Lexan has a grayish/blue cast when looked at from the edge. Clear
acrylic is generally water clear to very, very sligthly warm amber
tinged when looked at the same way. If your have a piece of each, the
difference is obvious, otherwise, perhaps not.

That said, using a sharp handsaw or hacksaw, cut off a small strip,
1/4" wide by 1" long is plenty. Put it on a hard surface, or mount
halfway in a bench vise, and whack firmly with a small hammer. If
acrylic, it will shatter or snap like glass. Polycarb will just bend,
tear or deflect the blow.
