What is Quarter & Rift Sawn?
Quarter sawing
Quarter sawing refers to a technique of cutting boards from logs. Quartersawn boards show striped grain lines and have greater stability than flatsawn wood. Overall quartersawn boards are less likely to warp, and there's less chance of shrinkage in white oak hardwood.
Rift sawing
Rift sawing is another technique of cutting boards from logs, different from quarter sawing. Each board is cut along a radius of the original log, so that the saw cuts at right angles to the tree's growth ring. Lumber that is rift sawn is highly stable, but produces a great deal of waste (in the form of wedge-shaped scraps from between the boards). Therefore it's a less-commonly used technique than flat sawing and quarter sawing. The waste may be used as firewood or for some other purpose.
General Description of Quarter & Rift Sawn White Oak
The sapwood is light in color and the heartwood is light to dark brown. Quarter & rift sawn white oak produces boards that show straight striped grain and a distinctive ray and fleck figure.
Relative Abundance and Availability of Quarter & Rift Sawn White Oak
15.1 percent of total U.S. hardwoods commercially available. Readily available but not as available as red oak.
Working Properties of Quarter & Rift Sawn White Oak
- machines well
- nails and screws well although pre-boring is advised. Use galvanized nails because it reacts with iron
- adhesive properties are variable, but stains to a good finish
- can be stained with a wide range of finish tones
- wood dries slowly
Physical Properties of Quarter & Rift Sawn White Oak
A hard and heavy wood with medium bending and crushing strength, low in stiffness, but very good in steam bending. Great wear-resistance.

a) Results of tests on small clear specimens in the green and
air-dried conditions. Definition of properties; impact bending is height
of drop that causes complete failure, using 0.71-kg (50 lb.) hammer;
compression parallel to grain is also called maximum crushing strength;
compression perpendicular to grain is fiber stress at proportional
limit; shear is maximum shearing strength; tension is maximum tensile
strength; and side hardness is hardness measured when load is
perpendicular to grain.
b) Specific gravity is based on weight when oven dry and volume when green or at 12% moisture content.
c)
Modulus of elasticity measured from a simply supported, center-loaded
beam, on a span depth ratio of 14/1. To correct for shear reflection,
the modulus can be increased by 10%.
