Eight Ball-SG Bill of Materials
DO NOT PURCHASE ANY MATERIAL UNTIL YOU READ THIS SECTION
LUMBER: Pine, Douglas-fir, mahogany, spruce, or most any type of good quality
clear wood can be used. Lumber is 1" and 1-1/4" lumberyard stock that
will usually finish to 3/4" and 1-1/16" net thickness. All widths are
NET while the noted lengths allow for trimming to size.
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. 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 letters A, B, and C with A being best, etc. The best face of
all panels should be the one exposed. Exterior AB grade plywood is acceptable
for a boat of this size and type. Check the PLYWOOD LAYOUT on the Full Size
Patterns for methods of utilizing the listed plywood to obtain the various
parts.
GLUE: All permanent joints should be glued with epoxy adhesives or epoxy resin
putty. Resorcinol or plastic resin glue may be substituted for wood to wood
junctions.
