Abstract:: The response of three hardwoods from Ghana and a hardwood and three softwoods from the United States to liquid and gas-phase impregnation was investigated. Impregnation with liquids included a sink-float test in a water-glycerine solution and pressure treatment with a copper sulphate solution and creosote under identical treating conditions. Flow...

Abstract:: Eight series of untreated posts (including five series of steel), 18 series of nonpressure-treated posts, and II series of pressure-treated posts remain in test at the Oregon State University post farm in western Oregon. So far all posts have failed in 36 untreated series, 33 nonpressure-treated series, and 2 pressure-treated...

Abstract:: 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...

Abstract:: Joints were fabricated from different combinations of untreated and fire-retardant- treated (FRT) Douglas-fir dimension lumber and 3/8-inch plywood. Eight types of fasteners and three fire-retardant treatments were tested. Joint specimens were exposed 2 and 7 years in cold, standard, and warm-humid conditions, then tested in lateral bearing. Best overall performance...

Abstract:: Eight series of untreated posts (including 5 series of steel), 22 series of nonpressure-treated posts, and 13 series of pressure-treated posts remain in test. Series in which all posts have failed now number 36 for untreated and 29 for nonpressure-treated. Causes of failures since 1949 were: fungi, 75 percent of...
