BlackEagle: I'm going to throw your tip back at you:
That IPS Weld-On #4 adhesive that you recommended, contains Methylene Chloride which, beyond being a known carcinogen, is also used to seal cracks in drilled/cut polycarbonate.
So once you've got your cut edge somewhat polished, you can brush some of it on there, to prevent any cracks from growing.
As for polycarb, I order 6" by 6" by 1/4" sample sheets from McMaster (sorry if ya'll aren't in the US, PM me if you want, maybe I can get a group order going), at $1.99 each. I'll be gluing two of those to make a 1/2" sheet, for my block.
