Lots of fill and sanding. Mixed glass microballoons with phenolic for filling on the sides. The bottom, below the Cedar chine, will be all graphite powder black but the sides and top will be natural wood finish.
Bought another 1"X8"X8' piece of dark color Western Red Cedar today. This will be cut into strips for the front deck and mixed with balsa for lightness and color differentiation. Think I have the pattern worked out. Keeping it simple.
Glassed the bottom yesterday afternoon. Used slow (2:1) epoxy/hardener. Not totally cured yet. Sands gummy.
Several bad spots, where the glass pulled away, bubbled or the epoxy got sucked up. Nothing that can't be fixed.
Tooks 21 oz of epoxy.
Later I epoxied the Kevlar on the nose and bonded the tube for the rudder mount.
Had to put Glad Wrap on the rudder mount because the piece of fiberglass was only 3 inches wide and it did not want to lay down.
Lessons learned so far:
Balsa does not cause splinters, Cedar does.
Fiberglass needs to be stretched both ways to prevent bubbling.
Need to be careful not to pull fabric away from concave surfaces when glassing.
Planking does not work as well as strips even with balsa. 4" wide is too wide to compound bend properly. Even 2" is too much.
I'll think of some more here.
