Quarter sawing or quartersawing is a woodworking process that produces quarter-sawn or quarter-cut boards in the rip cutting of logs into lumber. The resulting lumber can also be called radially-sawn or simply quartered .
Bentham was a British naval engineer with many shipbuilding inventions to his credit. Veneers at the time of Bentham were flat sawn, rift sawn or quarter sawn; i.e. cut along or across the log manually in different angles to the grain and thus limited in width and length. [citation needed]
Rip cuts are commonly made with a table saw, but other types of power saws can also be used, including a radial arm saw, band saw, and hand held circular saw.In sawmills the head saw is the first rip-saw a log goes through, which is sometimes a gang-saw, and then the cants may be resawn using other saws and then edged in an edger and sometimes cut to length by a crosscut saw.
This yields veneer that looks like sawn pieces of wood, cut across the growth rings; such veneer is referred to as "crown cut". A half-round lathe in which the log or piece of log can be turned and moved in such a way as to expose the most interesting parts of the grain, creating a more textured feel and appearance; such veneer is commonly ...
Rift sawing is a woodworking process that aims to produce lumber that is less vulnerable to distortion than flat-sawn lumber. Rift-sawing may be done strictly along a log's radials—perpendicular to the annular growth ring orientation or wood grain—or as part of the quarter sawing process.
The main categories of engineered lumber are: [29] Laminated veneer lumber (LVL) – LVL comes in 1 + 3 ⁄ 4-inch (44 mm) thicknesses with depths such as 9 + 1 ⁄ 2, 11 + 7 ⁄ 8, 14, 16, 18 and 24 inches (240, 300, 360, 410, 460 and 610 mm), and are often doubled or tripled up. They function as beams to provide support over large spans, such ...
