coefficient .00186; 50% more stable than red oak).
DURABILITY: Strength values are similar to
those of American oak.
Workability
SAWING/MACHINING: Moderate ease in working
with hand and machine tools; silica in wood dulls tools quickly: carbide
tooling is recommended.
SANDING: Clogs abrasives; frequent sandpaper
changes are required.

FINISHING: Natural oils may interfere with
adhesion and drying of some finishes. To reduce the wood’s tendency to
repel finish coats, surface resins may be removed with a solvent that
is compatible with the finish to be used.

it does not cause rust or corrosion when in contact with metal. Respiratory
and dermatological allergic potential.
