    Description

    Woods-run bolts in 4- and 6-foot length from poletimber stand thininings were classified into five quality classes, and the absolute sweep was measured for each bolt. Cants 4 by 4 and 4 by 6 inches were sawn from these bolts. The cants were classified by an interim classification system for the production of pallet parts. In contrast to straight bolts, sweep from 0.6 to 1.0 inches in bolts from 6 do 10 inches in diameter reduces the yield of patllet cants approximately 5 percent; 1.1 to 1.5 inches of sweep reduces the yield approximately 10 percent. The quality mix of pallet cants produced from woods-run bolts is sufficient for commercial pallet production when unsound bolts and those with sweep in excess of 1-1/2 inches are eliminated. No need for a more detailed pallet bolt classification system was indicated.
