Glass Bottom Bill of Materials
LUMBER: Do NOT purchase any lumber until you read this section. Do NOT
purchase any NET SIZED material. All lumber thickness specified should be
purchased as standard lumberyard stock finished as full as possible. As an
example, 1" stock is NOT to be a net thickness of 1". Stock 1"
thick refers to lumber purchased as "four quarters" material that
will finish from 3/4" to 7/8" in net or actual thickness. Widths,
however, are noted as "net" unless specified otherwise. (Exception:
All 2" thick stock is lumberyard size in both thickness and width.) Stock
listed as 1" x ½" is to be ripped from standard 1"
material. Purchasing random-random material to re-saw to the required size will
result in considerable savings. Some suitable boatbuilding woods include
mahogany (dark red Philippine, Honduras, or African) clear vertical grain
Douglas-fir, Sitka spruce, white oak or longleaf yellow pine. Similar woods,
available in the building locale and common to boatbuilding, may be substituted
at the discretion of the builder. The prototype was built primarily from dark
red Philippine mahogany. Check all listings to the work prior to purchasing
materials.

| 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 and have inner voids not apparent to the eye. In most cases, the glues
used in both marine and exterior panels are the same, however, the decision to
use exterior in lieu of marine panels for planking must lie with the builder.
Most exterior plywood is not ¼" thick; it is classed as
"scant" and is a fraction less than full thickness. Take care if
mixing marine and exterior panels that must butt join. Marine plywood is
recommended, especially for the bottom. Douglas-fir plywood is acceptable in
all cases although other species of suitable grade may be used alternately. The
grade of the exterior veneer of plywood panels is identified by the letters A,
B, and C. For planking the A-A (best) grade is desirable. The best face of all
panels should be the one exposed. Check the PLYWOOD LAYOUT in these
instructions and the text for method of utilizing the listed plywood to obtain
the various parts. |
