All right time for a photo update.

Added (1) 1208 and (3) 1700 to inside skin along with 8 & 12" 1708 tabbing.
Laminated 2 pieces of 3/4" marine ply and one 1/2" marine ply. Let it cure after applying neat epoxy to all inside faces and troweling on a cabisol, cotton flocking mixture with a 1/4" notch trowel. Squeezed it together with a 300 lb steel plate and screws and a coupe bags of concrete mix. When I cut the top curve the laminate looked solid with no gaps. I then a coated the back and sides of the core with neat epoxy and troweled on the cabosiol mix on the inside skin and back of the core. Pulled it all together with some long 24 and 30" clamps that I welded up along with a handful of 2x6x18" blocks inside and out, thru bolted with 1/2" rod.
Pulled fillets on the inside and added 8 &12" 1708 tabbing. Then laminated it with (1) 1208 and (4) 1700; wrapping 3 layers over the top and down the back staggered to 5".
