DescriptionUsing a new computer grading program (UGRS), 1 and 2A Common lumber was sorted based on the percentage of board surface measure found in the maximum allowable number of grading cuttings. For 1 Common, 46.0 percent of 921 boards had percentages in the FAS range (83-1/3% and above). For 2A Common, 54.7 percent of 825 boards had percentages in the 1 Common range. When gang-ripped first, these quality sorts produced important differences in the number of rips, crosscuts, and parts produced for primary and salvage operations when processed to easy and difficult cutting bills. In addition, important differences emerged in the cost and amount of lumber required for each of the quality sorts.
