A comparative economic analysis between log scaling practices

Creator:: Lewis, Charles Stewart
Abstract:: Many centers of population in the Pacific Northwest are dependent upon employment in the forest based industries. Mary of these timber dependent communities look to the public forests for their raw wood requirements. In some localities the installed capacity has outstripped the local wood supply. This necessitates reaching into other...

Probability proportional to size sampling of Douglas-fir from aerial photography

Creator:: Rogers, Roger Allan
Abstract:: This experiment was designed to investigate the use of volume estimations from aerial photography and probability proportional to size (PPS) sample selection in the development of a practical sampling design for timber volume estimation on small land areas of Pacific Northwest Douglas -fir (Pseudotsuga menziesii, Franco). The major problem of...

The effects of thin kiln sticks on the drying of two inch western hemlock lumber

Creator:: Horton, Robert Kenneth
Abstract:: New technology allows the production of thinner kiln sticks manufactured of phenolic resin impregnated paper which are both structurally and economically realistic. This project tested the effects of kiln stick thicknesses on dry kiln air circulation and on lumber drying degrade. Three variables, stick thickness (3/4, 9/16, 7/16 and 1/4...

Steam-jet heat recovery in a lumber dry kiln

Creator:: Masters, Keith R. W.
Abstract:: Lumber drying accounts for about 70 percent of sawmill energy requirements. Significant recovery of energy used to dry lumber would result in significant energy recovery for the mill. This is desirable because of today's high cost of energy. The objective of this study was to recover some of the energy...

Pollutants leached from selected species of wood in log storage waters

Creator:: Graham, John LeRoy
Abstract:: A study was conducted to determine the quantity and character of substances leached from logs floating in water, and the rate of leaching of these substances. The species of wood studied were Douglas fir and ponderosa pine. The research was carried out in a controlled laboratory environment with log sections...

A method for approximating distributions of mechanical properties for structural lumber

Creator:: Fernandez, Virgilio Asuncion
Abstract:: The present method of design for walls does not accurately predict the strength and stiffness of walls because load sharing and composite action are not taken into consideration. This results in the use of higher strength materials and walls which are overdesigned. A new method of design for walls using...

Drying Oregon white oak lumber

Creator:: Espenas, Leif D., Kozlik, Charles J., and Oregon State University. Forest Research Laboratory
Abstract:: Oregon white oak, Quercus garryana Dougl., could have greater commercial use, but information on its drying properties is lacking. All oaks are difficult to dry, and the initial kiln conditions are important to prevent excessive surface checking and honeycombing. This study illustrated that a maximum dry-bulb temperature of 110 F...

BOD and toxicity of log leachates

Creator:: Atkinson, Sheridan William
Abstract:: A series of log storage experiments were conducted to determine whether leachates derived from water storage of logs are acutely toxic to fish. Log segments approximately 18 inches long and 16 inches in diameter were stored in tanks and held submerged for a period of 7 days. The holding water...
