![]() |
| Sample is square-edged solid strip. Top portion is finished with a water-based urethane; the bottom with an oil-modified polyurethane. |
Appearance
COLOR: Heartwood is light brown; some boards
may have a pinkish tint or a slight grayish cast. Sapwood is white to
cream.
GRAIN: Open, with longer rays than red oak.
Occasional crotches, swirls and burls. Plainsawn boards have a plumed
or flared grain appearance; riftsawn has a tighter grain pattern, low
figuring; quartersawn has a flake pattern, sometimes called tiger rays
or butterflies.
VARIATIONS WITHIN SPECIES AND GRADES: Considerable
variation among boards in color and grain texture, but variations not
as pronounced as in red oak.
Properties
HARDNESS (JANKA): 1360; 5% harder than Northern
red oak.
DIMENSIONAL STABILITY: Average (change coefficient
.00365; 1% more stable than red oak).
DURABILITY: More durable than red oak. Tannic
acid in the wood protects it from fungi and insects.
Workability
SAWING/MACHINING: Excellent machining qualities.
SANDING: Sands satisfactorily.
NAILING: Good resistance to splitting; excellent
holding ability.
FINISHING: Absorbs finishes more evenly than
red oak. Does not bleach well.
COMMENTS: During the finishing process, tannins
at the surface can react with some liquids to turn the wood green or brown.
This effect tends to be more pronounced with products that have a high
water content, such as bleach and water-based finishes.
Cost (relative to
plainsawn select red oak)
MULTIPLIER: 0.95
