Amp Eater Bill of Materials
DO NOT PURCHASE ANY MATERIAL UNTIL YOU READ THIS SECTION.
LUMBER: White oak, mahogany (Philippine or Honduras), spruce, or
similar types of wood common to the area for boatbuilding can be used. Seat
cleats and similar members that impart no great structural strength may be
almost any good grade of lumber. The wood should be knot free (small solid ones
are permissible), properly dried, and free of splits. Lumber designated as
1" is "four quarters" lumberyard stock, usually finished to
3/4" net thickness. All widths are NET and the noted lengths allow for
cutting to fit. However, lumber noted as 2" stock is lumberyard size in
both length and width (e.g. A 2" x 6" will usually net 1 1/2" x
5 1/2"). NOTE: The following listing is for the basic hull only. The
types of lumber listed are as used on the prototype; spruce for light weight
and mahogany for appearance. As stated in the prologue, other species can be
substituted. Although the sizes are noted individually, it is best to group the
lumber, purchase "random/random" (varying widths and lengths)
lumberyard stock, and rip and trim to the required sizes. CHECK ALL SIZES
TO THE WORK PRIOR TO CUTTING.
Abbreviations used are: Mahog = mahogany; Sp = spruce: DF = Douglas-fir.

PLYWOOD: All plywood must be intended for marine or
exterior use. Interior grades are NOT acceptable. Marine plywood has higher
grade inner plies, while the exterior grade cores may be of inferior material
with inner voids not apparent to the eye. In most cases, the glues used in both
marine and exterior panels are the same. A solid core marine grade is
preferable, although an exterior grade can be used with the understanding that
unseen interior voids can cause problems. Douglas fir plywood is acceptable,
but high quality Okoume, mahogany, or other decorative veneer (usually imports)
are preferable. The grade of the exterior veneer of plywood panels is
identified by the letters A, B, and C with A being best, etc. The best face of
all panels should be the one exposed. Any patches on lower grade veneers should
be on the interior, especially on the forward bottom. Check the PLYWOOD LAYOUT
on the Full Size Pattern sheet 1 of 2 for method of utilizing the listed
plywood to obtain the various parts.
Abbreviations used are: DF = Douglas-fir; PW = plywood; Ext. = exterior; Mar. =
marine. |
