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.
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.
Odsus1 00:21, 22 October 2018 (UTC)The description of rift sawn in this article is absolutely incorrect, rift sawn is defined as sawing a log in a manner where the grain is between 30-60 degrees to the flat face of the board and is not rare at all, quarter sawn is defined as 60-90 degrees to the flat face of the board.
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 .
The pit saw was "a strong steel cutting-plate, of great breadth, with large teeth, highly polished and thoroughly wrought, some eight or ten feet in length" [17] with either a handle on each end or a frame saw. A pit-saw was also sometimes known as a whipsaw. [18] It took 2-4 people to operate.
Dyera costulata, the jelutong, is a species of tree in the family Apocynaceae.It grows to approximately 60 metres (200 ft) tall with diameters of 2 metres (5 to 6 ft), or even to 80 m (260 ft) tall with diameters to 3 m (10 ft), [3] and boles clear and straight for 30 m (90 ft).
Lumber produced by flat sawing from a log. Plank A has been cut from the middle, and is as wide as the original log. Plank B has been cut closer to the side, and shows slash grain. Flat sawing, flitch sawing or plain sawing is a woodworking process that produces flat-cut or plain-cut boards of lumber. [1]
In woodworking and construction, a nail is a small object made of metal (or wood, called a tree nail or "trunnel") which is used as a fastener, as a peg to hang something, or sometimes as a decoration. [1]
