Joe, I used about eight 4'x8' sheets of 1/4" polycarbonate to make a greenhouse, and did many cuts with a portable circular saw with a fine-tooth blade, and a fine-toothed hand saw. I also drilled many holes. I never experienced cracking or chipping. As far as I know, the polycarbonate I used (Cyrolon) is no different from that sold under the Lexan brand name. I used the stuff because it is hammered by 4' thick chunks of ice and snow sliding off our roof, and it doesn't flinch. Fifteen years of UV from vertical sunlight at 7400' elevation has caused some clouding, but in your application it would be forever. If you like, send me your address, and I will mail you a chunk of the PC to play with. By the way, nice looking boat. Tom Jenkins M17 Scintilla On Mar 23, 2010, at 10:14 AM, Joe Murphy wrote:
Has anyone ever worked with either Lexan or Plexiglass? I'm thinking of making companionway doors but I keep hearing about how difficult it is to cut the material without it chipping and cracking.
