Tanoak lumber might supplement the supply of white oak for boat construction, as the tree has extremely thick sapwood that can be pressure- treated readily with preservatives.
One-inch tanoak lumber was kiln -dried to 3 different moisture content ranges, then pressure -treated with water -borne preservatives. Some unseasoned lumber was...
Checking was influenced b drying conditions. This influence was greatest before average moisture content reached 20 per cent, but tension in surface layers caused checking even below this point.
Neither high initial dry-bulb temperature nor initial conditions of high equilibrium moisture content were conducive to checking.
High temperature and high...
Need for increased outlets for common boards led to a study of lalllinated bevel siding.
Low-grade boards of Douglas fir and ponderosa pine were bonded with exterior glue to veneer covering and resin-fiber overlay to form panels subsequently ripped to width and bevel-sawed into siding,
Grooves in the lumber core,...
