Tiller Layup,
In contact with the foam, one layer of hybrid braided tube or hybrid tape (the
bi-directional type). Two pieces of unidirectional 3 inch wide carbon tape
placed longitudinally, make the overlap on the top and bottom surfaces, then a
layer of carbon braided tube that extends 24 inches from the fat end towards
the thin end, and finally a layer of braided carbon tube on the outside.
Lightly sand smooth and cover the outside with 207special hardener / epoxy.
You can remove the foam internally with acetone if need be especially at the
forward and back ends. Fill the ends with epoxy 410/graphite to 1) strengthen
the joint to the cassette, 2) provide a small exit hole on the top front
surface for shock cord exit for the extension keeper system. Drill and ream a
hole in the underside of the tiller about 8-12 inches back from the front. You
can pass 2 pieces of shock cord through the tiller from the bottom hole and out
through the hole in the front of the tiller, connect to the extensions. Tension
the shock cord and tie a knot in the bottom just outside the hole.

PS Mark you received a 5 page illustrated handout on making CB and rudders with
your cores.

How many layers of carbon would you use or what is the recommend layup?
