Poly-carbonate sheet is used in professional machines for chip control and operator safety. Used in Police riot shields. Don't use acrylic as it shatters. Even poly-carbonate will stress rack eventually if you make the fixings too tight - I need to replace the screens in my Beaver Partsmaster again having done it about four years ago - bolt holes should have had appreciable clearance for expansion and contraction, but I made them bang on :(

Thanks, suggested minimum thickness?

Just saw a good vid where the guy was using small alu extrusion (looked like 20 x 20) for the frame, might try that.

Something like this might be good -

I used 5 mm on both my Fanuc Tapecut Model L wire eroder and my Beaver Partsmaster CNC Mill

Would this work?

NO, because each skin is very thin - it's the over all thickness they quote. You need solid polycarbonate

Ok, thanks. Im getting prices of around £120 per 1m^2 5mm Polycarbonate. Does this sound right?
