Francis Drake-PW Bill of Materials
The following list of materials is intended to be a general guide only.
Before ordering any materials, the text and plans should be checked for
possible options. All lumber listed as 1" stock is to be standard
"lumberyard four-quarter" material which when finished may vary to
somewhat less or slightly more than 3/4" in thickness. All widths are NET
and all lengths allow for cutting to fit. Grouping lumber and purchasing
random-random material to resaw to the required size will result in
considerable savings. All lumber used should be first grade free from shakes
and knots. Lumber typical to the locale and proven in use in boats in the
locale of similar type and size can be used. Suitable woods include white oak,
mahogany (both Philippine and Honduras types), Sitka spruce, Douglas-fir,
longleaf yellow pine, Port Orford cedar, apitong, and teak. All plywood (PW) is
to be marine (MAR) or exterior (EXT) grade. The marine-type is preferable as
the inner cores are solid and thus the panel has more structural integrity.
Douglas-fir (DF) is satisfactory with the quality of the exposed faces of the
veneer being designated by the letters "A" or "B". The
"AA" grade panels are always preferable, however, "AB"
grade is acceptable. All plywood should be a minimum of five plies, if
available. All fastenings should be bronze or hot dipped galvanized ferrous
metal. Brass fastenings are not advised nor are the electroplated screws
commonly sold in hardware stores. All screws are to be of the flat head type
intended for wood. All nails are of the ring-type nail common to boat
construction. Unless otherwise specified, all wood-to-wood joints are to be
glued with a waterproof or highly water resistant glue such as plastic resin,
resorcinol, epoxy, or other equivalent type used per the manufacturer's
instructions regarding temperature, clamping requirements, curing time, and
mixing method.
