River Rat-PW Bill of Materials
DO NOT PURCHASE ANY MATERIAL UNTIL YOU READ THIS SECTION.
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 oak (white
oak), Douglas-fir, 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.
CHECK ALL SIZES TO THE WORK PRIOR TO CUTTING. Abbreviations used are: Mahog =
mahogany; DF = Douglas-fir.
