to be reused, bond the fasteners with epoxy.
4.3 Removing and replacing a damaged section
Often damage to a frame is limited to a small section or the frame may be too difficult
to remove. You may be able to replace only the damaged portion, restoring the
strength of the frame while leaving the frame in position in the boat.
1. Cut out the damaged section of the existing frame. Trim the exposed ends to a
minimum 8-to-1 scarf angle (Figure 4-4). The longer the scarf angle, the stronger the
joint. When repairing hardwood or highly loaded frames, use a longer (12-to-1) scarf
angle.
Figure 4-4 Cut out all of the damaged area, leaving at
least an 8-to-1 bevel on the ends of the damaged frame.
