what is the technical efficiency of the mill. diameter 16-foot-long log is 0.240 inch for a mill cutting dimension lumber (fig. 4a). If the kerf on this log is reduced to 0.180 inch, the pattern shift results in a 2 by 6 rather than a 2 by 4, with an increase in lumber yield from 64 to 69-1/3 board feet–an 8.3 percent increase (fig. 4b).
