Sea Kayak Two
Bill of Materials
DO NOT PURCHASE ANY MATERIAL UNTIL YOU READ THIS SECTION.
LUMBER: Pine, mahogany, spruce, or most any type of
clear wood can be used. Lumber is 1" lumberyard stock,
usually finished to 3/4" net thickness.
PLYWOOD: All plywood must be intended for marine or
exterior use. Interior grades are NOT acceptable. Marine
plywood has higher grade inner ply cores, while the exterior
grade cores may be of inferior material with inner voids not
apparent to the eye. In most cases, the glues used in both
marine and exterior panels are the same. When SEA KAYAK TWO
is built with 1/4" plywood, an exterior grade is
satisfactory, however, a marine grade or solid core is
preferable for 4 mm planking. Douglas-fir plywood or any
suitable marine grade veneer plywood may be used. The grade
of the exterior veneer of plywood panels is identified by the
laters A, B, and C with A being best, etc. The best face of
all panels should be the one exposed. Check the PLYWOOD
LAYOUT on the Full Size Patterns for method of utilizing the
listed plywood to obtain the various parts.
GLUE: All permanent joints should be glued with epoxy
adhesives intended for wooden boat use. These may be epoxy
resin with additives or epoxy glue.
