Thanks Greg ?

 

Who has braided hybrid tubes?  I?ve only seen carbon sleeves from Sweet?
When I purchased Carbon Tape, only 1 ½ was available.  Is 3? now available?

 

To your health,

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?
