Workability
SAWING/MACHINING: Sawing is difficult due to high density; requires frequent resharpening of tools. Planing is difficult due to interlocked grain. Can be machined to a smooth surface. Carbide tooling recommended.
SANDING: Sands well.
NAILING: Good holding ability, but due to hardness may require adjustment of angle of penetration and/or height.
FINISHING: No known problems.
COMMENTS: Light-sensitive; darkens rapidly upon exposure to sunlight.
