Workability
Density and interlocked grain make it harder to work with. Lumber with less interlocked grain can be surface planed to a smooth finish. Expect moderate blunting effect on cutting tools if lumber contains silica. High oil content and density make gluing difficult. Before nailing or screwing, pre-boring is required.
