Appearance
Color: Sapwood
is gray-white; heartwood is salmon red to orange-brown when fresh,
and becomes russet or reddish brown when seasoned; often marked with
dark streaks.
Grain: Mostly
interlocked; texture is medium to rather coarse.
Variations
Within Species And Grades: Moderate
to high color variation.
Properties
Hardness/Janka: Janka:2820;
119% harder than Northern red oak.
Dimensional
Stability: Average
(8.5; 1% more stable than Northern red oak). However, actual
installations have shown significant movement. Longer-than-normal
acclimation time is recommended.
Durability:

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: Scratches
are easily seen. Each sanding must carefully remove the scratches
from the previous cut, or sanding marks will be visible in the
finish.
Nailing: Due
to hardness it is very important that the angle of penetration be
adjusted carefully. If using a pneumatic nailer, the air pressure
should be adjusted.
Finishing: Coating
with oil-modified polyurethane may occasionally cause white spots or
specks, as well as white end joints, to appear. This may be avoided
by buffing in a clear oil sealer or neutral stain, then buffing on
satin polyurethane.
