Tunnel Mite 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. 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 is to
be marine or exterior grade. The marine-type is preferable as the inner cores
are solid and thus the panel has more structural integrity. Douglas-fir 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.
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.
