The "quarter" system of reference is a traditional North American lumber industry nomenclature used specifically to indicate the thickness of rough sawn hardwood lumber. In rough-sawn lumber it immediately clarifies that the lumber is not yet milled, avoiding confusion with milled dimension lumber which is measured as actual thickness after ...
Rift-sawing may also be described as lumber produced during latter stages of stepped cuts on a quarter round, where the subsequent cuts are parallel to either of the initial quartering cuts. The AWI defines "rift sawing" as a technique of cutting boards from logs so the grain is between 30–60° to the face of the board, with 45 degrees being ...
Wood grain is the longitudinal arrangement of wood fibers [1] or the pattern resulting from such an arrangement. [2] R. Bruce Hoadley wrote that grain is a "confusingly versatile term" with numerous different uses, including the direction of the wood cells (e.g., straight grain, spiral grain), surface appearance or figure, growth-ring placement (e.g., vertical grain), plane of the cut (e.g ...

Sawtooth oak trees also grow at a faster rate which helps it compete against native trees. The wood has many of the characteristics of other oaks, but is very prone to crack and split and hence is relegated to such uses as fencing. [10] Charcoal made using this wood is used especially for the braziers for heating water for the Japanese tea ...
It is possible to dry 12/4 Red Oak fresh off the saw to 7% in 11 days. Since wood is dried with a vapor gradient - vapor pressure to ambient pressure - humidity can be kept very high. Because of this, a good vacuum kiln can dry 4.5" thick White Oak fresh off the saw to 8% in less than a month, a feat that was previously thought to be impossible.
