The Forest Products Laboratory (FPL) has developed five house plans for low-cost rural houses to demonstrate cost-saving principles of construction, The plans feature simplicity of design, but provide structurally sound houses that fulfill the needs of many families. To determine to what extent the plans were used, how they met the needs and the acceptance standards of low-income families, and how they could be improved, a questionnaire was mailed to 1,620 individuals who requested and were sent the FPL plans during 1969. A total of 1,129 responded. The replies indicated that 225 houses...

Large volumes of red pine (Pinus resinosa) from plantations in the Lake States and the Northeastern States are about to appear on the saw log market. One of the most important products of small saw logs is studs (2 in. x 4 in. x 8 ft.). A study has been conducted by the FPL which examines the relationship of two industrial and one FPL sawing method on the subsequent warp in the studs from this species. Results generally indicate that the species is suitable for studs. There is significantly less warp in studs sawn by the FPL method than the industry methods. Also one of the industry...

The Problem: How to determine the number of days required for air-drying lumber to 20 percent moisture content. The Answer: By developing an annual calendar of effective drying days.

A comparison was made between the air-drying rates of rough and presurfaced northern red oak and white oak. In both species, the presurfaced material was about 1/8 inch thinner than the rough material and dried faster than the rough material. The reduction in drying time depends on the method of analyzing the drying curves, but is slightly less than 10 percent.
