The frames that had crumbled or fallen apart were replaced first .
That way the semi intact ones could be used as guides to fair in the
shape of the new frames as they were being replaced .
the new frames were made of white oak . White oak has
been used in boats for centuries and has excellent decay resistance .
The frame components are bonded to each other with 3M 5200 and bolted
with stainless steel carriage bolts .
With all of the frames replaced a batten is used to check the
fairness of the frames ( 1 ) . Any high spots on the frame
are smoothed off with a plane allowing the batten to lay continuously
across all of the frames without bumps or hollows . With
the frame work fair the stem is replaced next (2) . The joint where
the planking lays into the keel is called the rabbet . This is a
constantly changing angle along the length of the boat .
Notches are made at each frame with a sharp chisel (3) , then
they are connected into a full length notch that will receive
the planking .
