I'm doing a hollow wooden board 5'5''. But need advise if its gonna be strong enough or I should add some more wood for strength?
Skeleton is lasercut in 4mm plywood for ribs and 2x3mm plywood for stringer (mirror cut), thinnest parts are 8mm.
150mm between ribs. Extra 4x4mm wood strips 80mm appart for stiffness and more glue surface. Rails, tip and tail are to be solid in balsa. Deck in 4mm balsa (100x1000mm sheets).
The idea is to epoxy glass it 4+4 and 4.
Skeleton as on picture weighs 0,5kg
Any thoughts about this, am I way of or on the right track?
