Stitching Together a Plywood Sea Kayak.

This video shows the process of converting small piece of plywood into the parts of an 18' long sea kayak. The CNC cut plywood panels are assembled together with CA glue. These panels are then wired together with copper wire to hold them in the shape of a boat while more CA glue is used to spot weld the seams together. After the wire is pulled out, epoxy thickened with wood flour is piped into the seams and smoothed with a plastic spoon to create a fillet. The inside of the boat is then reinforced with fiberglass.
