My understanding was that acrylic is easy to drill, polycarb needs a special drill bit or it'll crack, and birch merely splinters if you make a mistake--not crack.

Again you can not laser cut polycarb with a commercially available machine.

I never, EVER, said you COULD cut polycarb on a laser. If you can show me where EXACTLY I said that, by QUOTING, then I'll retract this statement. Otherwise, leave any discussion of cutting polycarb by laser out.
