River Rat-Alum Bill of Materials
DO NOT PURCHASE ANY MATERIAL UNTIL YOU READ THIS SECTION.
The following is a listing of the primary aluminum members required to build
the RIVER RAT including their sizes, lengths, and/or square footage. The
listing will require some modifications depending on the version being built
and is to serve as a general guide only for cost estimating purposes and is not
meant to be all inclusive. Do not use this list to purchase materials without
first checking to the plans, Manual, and Instructions for options. In all
cases, the builder should check local sources for availability of stock sizes
as well as possible substitutes. How the members are obtained from the stock
and the manner in which the material is utilized can vary to suit sizes of
materials available where the boat will be built. This is why many members are
listed by square footage. In other cases, members may be made from flat bar,
plate, or sheet material. Also, square footage or linear footage may be given
for contoured members which can be cut to shape from plate or sheet stock, or
could optionally be formed or bent from flat bar stock. Sizes and areas include
an overage factor so that minor members not specifically noted can be obtained
from scrap material.
CHECK ALL SIZES TO THE WORK PRIOR TO CUTTING.
