Sawing Pattern Effect on the Yield of Furniture Components from High Quality Hard Maple Logs

The effect of three sawing patterns and five edging practices on the yield of furniture components from uniform, high quality hard maple logs has been investigated. It was found that live sawing, independent of subsequent edging practice, resulted in a 15 percent increase in the dollar value and surface area yield of furniture components compared to “sawing around” without setting out taper. The use of unedged boards, independent of previous log sawing pattern, resulted in a 4 percent increase of value and surface area yield compared to conventional or NHLA optimum edging practice. The application of live sawing combined with use of unedged boards resulted in a 20 percent increase in value yield. The surface area yield of edge-grain components was more than three times higher for live sawing than for sawing around. Sawing around the log produced 27 percent more surface area in sap cuttings than did live sawing.
