[PSUBS-MAILIST] Non developable surfaces

[hank pronk]

Joe,
My mbt outside windows are 1in thick.  I have no idea if they need to be that thick,  I would not hesitate to bend them to fit the curve.  I have not bent 1in but I have bent 1/2in and it was a breeze.  My rule, buy two pieces because I am sure to screw up the first  try.
Hank

The Markham submarine had instructions for blowing a bubble canopy.   I 
don't have a digital copy of those pages of the instructions.  Someone 
else might have it ... I think someone sent me a copy a few years ago, 
but I can't find that right now.
