Feather Bill of Materials
All fiberglass material should be of the marine-type often referred to as
"chrome treated" material which is free of dirt, grease, and oil.
Weights of fiberglass materials other than those listed are not recommended as
material which is lighter could affect the strength of the boat, while heavier
materials will only make the boat heavier and perhaps impair the performance.
Epoxy resins are not recommended as a substitute for the polyester types.
Lumber sizes listed refer to standard lumberyard size material except where
specifically noted as "net". For example, lumber listed as 1"
stock will be standard "four quarters" material which will finish
from 3/4" to 7/8" in finished thickness. All widths listed (second
figure) are net. All lengths allow sufficient material for trimming to exact
lengths. Material should be grouped together and purchased as
"random-random" material to be resawn to size for cost savings. The
term pine refers to the clear type free from excessive knots. Spruce refers
preferably to the Sitka variety. Mahogany refers to the Philippine type. Other
woods similar to these types and common to the locale may be substituted. For
wood members which will remain a part of the boat, the mahogany type is
preferable,. Other plywood types of the Exterior grade may be used alternately
also. For form members that are not to remain in the boat, pine or fir is
listed although any reasonably clear straight lumber can be used.
