Wing Mounts

- Glass tubes moulded from wings in 4x600DB E glass

- Drop onto deck on a bed of 403/411

- Tie this to inner skin with unis

- Tie to outer skin with uni

- Encapsulate all unis with one 200DB carbon.

Sound simple. Until you realize it is difficult to the deck gets in the way when you need to put the unis onto the inner skin. So, cut the deck back around the wing mount so it is narrower than the hull sides. Immediately before the deck goes on wet out the uni onto the inner skin then lay the top half over the top of the hull side. Drop the deck on (for good, apply glue) then fold the unis back on top of the deck.

There is a risk of poor lamination onto the inner skin, as all of this folding back and forth may wriggle it about, but luckily the springyness in the unis appear to hold them hard against the inner skin.

The rest of the laminating involved in the wing mounts is trivial.
