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
HARDNESS (JANKA): 1225; 5% softer than Northern red
DIMENSIONAL STABILITY: Above average (change coefficient .00263;
29% more stable than red oak).
DURABILITY: Natural resistance to insect infestation in
SAWING/MACHINING: Good machining and hand-tooling
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.
