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.

EPOXY RESIN: For gluing, laminating, epoxy encapsulation, and resin putty. (NOTE: Polyester resin can be used for resin putty and fiberglass cloth and tape application.

When using polyester, wood preservatives and adhesives [not listed] will be required.)
