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.
Riftsawn wood has every board cut along a radius of the original log, so each board has a perpendicular grain, with the growth rings oriented at right angles to the surface of the board. However, since this produces a great deal of waste (in the form of wedge-shaped scraps from between the boards) rift-sawing is very seldom used.
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.
Wood splitting (riving, [1] cleaving) is an ancient technique used in carpentry to make lumber for making wooden objects, some basket weaving, and to make firewood. Unlike wood sawing , the wood is split along the grain using tools such as a hammer and wedges , splitting maul , cleaving axe , side knife , or froe .
The larger pieces of wood that will not make lumber are chipped into wood chips and provide a source of supply for paper mills. Wood by-products of the mills will also make oriented strand board (OSB) paneling for building construction, a cheaper and in some use cases more robust alternative to plywood for paneling. Some automatic mills can ...
The longest plank in the world (2002) is in Poland (near Szymbark) and measures 36.83 metres (about 120 ft 10 in) long. Individual pieces of lumber exhibit a wide range in quality and appearance with respect to knots, slope of grain, shakes and other natural characteristics. Therefore, they vary considerably in strength, utility, and value.
Lumber Liquidators Flooring was started in 1994 by Tom Sullivan, a building contractor who began purchasing excess wood from other companies. He then resold the wood from the back of a trucking firm's yard in Stoughton, Massachusetts. Three years later in 1996, the company found their niche market in hardwood flooring.
According to Norse mythology, the first humans, Ask and Embla, were formed out of two pieces of driftwood, an ash and an elm, by the god Odin and his brothers, Vili and Vé. [1] The Vikings would cast wood into the sea before making landfall. The location of the wood would be an indication as to where to build their mead halls.
