Short-term heating of softwood veneer blocks temporarily softens the wood so that it can be peeled more readily. Heating reduces the depth of lathe checks and the likelihood of splitting and thereby increases the quality and quantity of veneer recovered. The softwood-plywood industry conventionally conditions blocks three ways: steaming blocks...
"We describe a test procedure developed during growth room and field trials for which we processed hundreds of test lots of seedlings, mainly Douglas-fir (Pseudotsuga menziesii) and ponderosa pine (Pinus ponderosa), as well as lodgepole pine (Pinus contorta), Jeffrey pine (Pinus jeffreyi), and Sitka spruce (Picea sitchensis), noble fir (Abies...
Production rates, skidding costs, and soil disturbance were compared for two partial-cut units-one with preplanned skid trails and winching and one conventional unit-harvested with a Caterpillar D-7F. For the unit with preplanned skid trails and winching, production was 11 percent less, and skidding cost per unit volume was 29 percent...
