Rudders / Daggerboards

I am making the rudders and daggerboards of foam, carbon fiber and Kevlar, laid up with epoxy and vacuum bagged.

 

Epoxing the foam together.

Epoxing an extra area of foam to move the joint to a less stress area.

Rudders cut out & the foil shape cut to depth with router.

Peal ply & breather in place. Extra beather where the suction cups go, to prevent a hight spot.

Cuting the holes for the vaccum cups.

Vacuum on. Jugs are to keep it flat.

Suction cup. Yes it's just one of those window thingys with a 1/4" hole drilled & a piece of 1/4 tube. The circle drawn on the bag is so I do not lose the hole.
