This study compares the machining properties of 15 individual species within B.C.'s SPF and hem-fir groups demonstrating the benefits of sorting by individual species. In addition, the machining properties of B.C.'s under-utilized species (e.g., trembling aspen, black cottonwood) are compared to those of well-established softwood species (e.g., Douglas-fir, western hemlock). Finally, the study determined the average force necessary to withdraw two types of fasteners (nail and screw) from each of the wood species.
