Topper 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. Although spruce (Sitka variety) and
mahogany (dark red Philippine type) are called out in the
listing, lumber typical to the locale and of similar types
and weights may be substituted. 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 three plies. 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.
