Dyno Mite Bill of Materials

LUMBER: Do NOT purchase any lumber until you read this section. Do NOT purchase any NET SIZED material. All lumber thickness specified should be purchased as standard lumberyard stock finished as full as possible. As an example, 1" stock is NOT to be a net thickness of 1". Stock 1" thick refers to lumber purchased as "four quarters" material that will finish from 3/4" to 7/8" in net or actual thickness. Widths, however, are noted as "net" unless specified otherwise. (Exception: All 2" thick stock is lumberyard size in both thickness and width.) Purchasing random-random material to re-saw to the required size will result in considerable savings. Some suitable boatbuilding woods include mahogany (dark red Philippine, Honduras, or African) clear vertical grain Douglas-fir, Sitka spruce, white oak or longleaf yellow pine. Similar woods, available in the building locale and common to boatbuilding, may be substituted at the discretion of the builder. The prototype was built primarily from Sitka spruce with dark red Philippine mahogany trim. Check all listings to the work prior to purchasing materials.

PLYWOOD: All plywood must be intended for marine or exterior use. Interior grades are NOT acceptable. Marine plywood has higher grade inner ply cores, while the exterior grade cores may be of inferior material and have inner voids not apparent to the eye. In most cases, the glues used in both marine and exterior panels are the same, however, the decision to use exterior in lieu of marine panels for planking must lie with the builder. Most exterior plywood is not 1/4" thick; it is classed as "scant" and is a fraction less than full thickness. Take care if mixing marine and exterior panels that must butt join. Marine plywood is recommended, especially for the bottom. Douglas-fir plywood is acceptable in all cases although other species of suitable grade may be used alternately. The grade of the exterior veneer of plywood panels is identified by the letters A, B, and C. For planking the A-A (best) grade is desirable. The best face of all panels should be the one exposed. Check the PLYWOOD LAYOUT in these instructions and the text for method of utilizing the listed plywood to obtain the various parts.

FASTENINGS: All permanent fastenings should be of a non-corrosive type. Screws as noted are of the flat head wood type, while nails are of the annular ring shank type commonly used in boatbuilding. Screws should be hot-dipped galvanized or preferably silicon bronze while nails can be bronze or Monel. Electroplated steel and brass fasteners are NOT advised. Carriage bolts are to be complete with nut and washer with galvanized being satisfactory.

Screws: Flathead wood type, bronze or hot dipped galvanized
