Seasoning and machining degrade in young-growth Douglas-fir dimension lumber

Creator:: Anderson, B. G., Knauss, A. C., Frashour, R. G., and Oregon Forest Products Laboratory
Abstract:: The increasing volume of young-growth Douglas-fir timber cut in the Pacific Northwest emphasizes the need for more knowledge on the characteristics of lumber sawed from these trees. The study described here was initiated to learn the extent arid causes of degrade resulting from kiln-drying young-growth Douglas-fir dimension lumber. At the...

Vapor drying of western woods

Creator:: Graham, R. D. (Robert D.) and Oregon Forest Products Laboratory
Abstract:: The vapor-drying process is described briefly and its present status in industry is discussed. Fairly extensive data on the vapor drying of 1-, 2-, and 4-inch Douglas-fir and 2-inch western hemlock lumber are presented. Exploratory work on the vapor drying of redwood, Pacific madrone, red alder and ponderosa pine is...

Sticker stain in one-inch red alder lumber

Creator:: Anderson, B. G., Frashour, R. G., and Oregon Forest Products Laboratory
Abstract:: The Oregon Forest Products Laboratory was asked in July 1953 by the Oregon Alder and Maple Company, Willamina, to work on the problem of dark stain which developed at sticker crossings in air-drying red alder (Alnus rubra, Bong.) during the summer months. Previous experience at the Oregon Alder and Maple...

Kiln-drying Oregon maple paper roll plugs

Creator:: Anderson, B. G., Williams, W., Jr., and Oregon Forest Products Laboratory
Abstract:: Four charges of S-inch paper roll plugs of Oregon maple were kiln-dried at various temperatures and humidities. The charge with the most desirable combination of short drying time and low degrade was dried to 12 per cent moisture content in lit hours, using a dry-bulb temperature of 160 degrees F...

Initial study of kiln drying clear Douglas fir planks

Creator:: Stillwell, H. D. and Oregon Forest Products Laboratory
Abstract:: 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...

Forest road location and design in the Douglas-fir region

Creator:: Barbieri, John Gillick
Abstract:: The purpose of this thesis is to outline the principles involved in the reconnaissance, survey, and design of forest roads in the Douglas-fir Region. The reconnaissance survey is the most important element in road location. Poor reconnaissance often results in abandonment of the route at considerable expense. The ground slope...

Seasoning and preservative treatment of tanoak lumber

Creator:: Miller, Donald J. (Donald James), Graham, R. D. (Robert D.), and Oregon Forest Products Laboratory
Abstract:: 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...
