RE: Foam core .40 size profile fuse?
Any of you bro's ever hear about "hoop pine" ply? Very strong, comes as thin as 1.5mm weighs 3.4 oz. sq.ft. and is bendable. Also 3.0mm and 6.0mm available. It will bend tighter than a wings leading edge. It passes a 70 degree water imersion test up tp 3 hrs. without failure. Sounds just right for cladding foam. There are also veneers on the market about 1/32" thick with two micro thin layers of phenolic backing ( for special glue applications ) Its tough to tear this stuff, but you can fold a piece to fit in your wallet. No specs on the weight of this. Joe
