Re: Quad Concave Body Board Study
Try thin foam core ,I am using two 5 mm sheets off airex laminated with 6 oz cloth covered with polyethylene foam to whatever thickness you need ,gets good flex .I think a thin plywood core would work well

Re: Quad Concave Body Board Study
It can be agonising building new boards being around it for weeks sometimes, knowing all the small imperfection and mistakes in it. I battle with symmetry getting the left and right side profiles exactly the same

New board
What a fantastic fulfilling hobby creating your own surfboards and the anticipation for the first test ride gives me goose bumps. Nobody seems to get this wing thing but when they light up down a wave face it is thrilling .This board is the longest most buoyant I have made. North Sea pleas bring wav...

Re: Quad Concave Body Board Study
I used to use contact glue but it is difficult to lay up large pieces, after some testing I now stick the pe with laminating epoxy it has the same adhesion as contact glue but gives time to move the pe around before it sets, with contact glue if you make a mistake its bad news. For the core lay the ...

Re: Quad Concave Body Board Study
Layered and veneered structures get stronger with concaves , it’s so easy to press form layered shapes .there are so many types of skin layering to try out .With polyethylene , cork ,etc it’s easy to change a shape or add to after testing

Re: Quad Concave Body Board Study
You can change twist and bend flex by adding layers of cloth down the core spine. I feel flex in a board is desirable

Re: Quad Concave Body Board Study
My boards are the same as a wood Paipo but with soft buoyancy draped on shaped in a teardrop form. I could use plywood but it is too heavy and lacks the bouncy and strength of Airx foam. The photos I sent deform the true shape of the board.
