: Very cool response, thanks Bill -- I never knew about mylar window
: film! I used Saran wrap over a piece of scrap plywood for my

: commercial builders use when laying up big boats with chop guns.

: Now, I wonder if I ought to drill small vent holes in the

Little vent hole is a good idea :)

I've done a single skin bulkhead in the past without it and they "breath" you can see them change shape as the pressure changes in the boat, a bit odd to see.
