[Public-List] Cockpit deck core job

[George Dinwiddie]

FWIW, I've found that the high-density klegecell (from fgci.com) works 
fine in both deck and cockpit sole.  (I hate their current website!)

Probably the foam would not have been strong enough without tabbing the 
upper skin back into one piece, though.  It's strength is rigidity in 
compression, not tensile.
