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.
Quarter sawing is sometimes confused with the much less common "rift sawing." [4] [5] In quartersawn wood, only the center board of the quarter-log is cut with the growth rings truly perpendicular to the surface of the board. The smaller boards cut from either side have grain increasingly skewed.
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.
Illustration of carpentry (charpente) in the French Encyclopédie showing hewing, mortising, pit sawing on trestles. Tools include dividers, axes, chisel and mallet, beam cart, pit saw, trestles, and bisaigue. The men talking may be holding a story pole and rule (or walking cane). Shear legs are hoisting a timber.
The section "Comparison to rift sawing" directly contradicts what is shown in the the AWI_Lumber_Cuts.svg diagram, cementing the confusion and ambiguity between rift and quarter sawn. I have no idea if the diagram is wrong or the paragraph is wrong, I just came here doing research on wood grain and found this serious flaw.
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]

Two-man saw in Oregon. A two-man saw (known colloquially as a "misery whip" [1]) is a saw designed for use by two sawyers. While some modern chainsaws are so large that they require two persons to control, two-man crosscut saws were primarily important when human power was used. [2]
