[Fot] Bending Lexan

[Duncan Charlton]

If you run out of options, it's not that hard to do it yourself.  I made 
a leading-edge lens for a landing light on an airplane and it turned out 
perfect.  You don't have to get it very hot but you do have to drive out 
the moisture to avoid forming bubbles.  Make it an inch or two bigger 
than the final dimensions because the edges will end up wavy if using 
only a male mold.  Unlike plexiglass you can cut it with a reciprocating 
saw without worrying about cracking it. Clean up the edges with a file 
and polish if you want to.  Plenty of info here: 
http://bbs.homeshopmachinist.net/threads/30224-How-do-you-bend-Lexan-or-polycarbonate 
.  There is mention of bending Lexan by using solvents but without 
testing I wouldn't try it on a full-size piece. Hydrocarbons cause it to 
craze badly so never spill fuel on it...
