Tunnel King 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, unless specified as
NET. 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), spruce (Sitka), 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; SP = spruce; DF = Douglas-fir; PW=plywood; Ext=exterior;
MAR=marine.
