Appearance
COLOR: Heartwood is yellow after cutting
and turns deep pinkish tan to warm reddish brown within weeks due to high
resin content. Sapwood remains yellow, with occasional blue-black sap
stain.
GRAIN: Dense, with high figuring. Plainsawn
is swirled; rift- or quartersawn is primarily pinstriped. Curly or burl
grain is rare.
VARIATIONS WITHIN SPECIES AND GRADES: Moderate
color variation.
Properties
HARDNESS (JANKA): 1225; 5% softer than Northern
red oak.
DIMENSIONAL STABILITY: Above average (change
coefficient .00263; 29% more stable than red oak).
DURABILITY: Natural resistance to insect
infestation in heartwood; dense.
Workability
SAWING/MACHINING: Good machining and hand-tooling
qualities.
SANDING: Tendency to clog paper due to high
resin content; begin with coarse grade.
NAILING: Good holding ability.
FINISHING: Accepts both surface and penetrating
finishes. Some stains may blotch; raising grain first may help. 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.
