A dado (US and Canada, / ˈ d eɪ d oʊ /), housing (UK) or trench (Europe) is a slot or trench cut into the surface of a piece of machinable material, usually wood. When viewed in cross-section, a dado has three sides. A dado is cut across, or perpendicular to, the grain and is thus differentiated from a groove which is cut with, or parallel ...
Diagonal- and stepped-cut rift-sawing is intermediate to flat-sawn and radial cut lumber. The angle of the bastard grain may differ along the width of the board or between opposing sides, and enhances the appearance of ray fleck. Flat-sawing is the quickest method, producing the least wood waste and largest possible boards from a log.
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]
The William Ritter Lumber Company (1890–1960), famous for its Appalachian oak flooring and other products, used a modified technique to reduce waste: bark and a few boards were removed from two opposite sides of the log; the log was cut in half (possibly, four quarters); each piece was placed on the flat side and "quartersawn" lumber was cut ...
The tendency for wood that is being cut to direct the saw parallel to its grain. lath. Also called a slat. A thin, narrow strip of straight-grained wood, typically arranged side-by-side with others and used to support roof shingles or tiles, as a backing material for plaster or stucco in walls and ceilings, or in lattice and trellis frameworks ...

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.
The Log Scaler measures the cut trees to determine the scale (volume) and quality (grade) of the wood to be used for manufacturing. When logs are sold, in order to determine the basis for a sale price in a standard way, the logs are "scaled" which means they are measured, identified as to species, and deductions for defects assigned to produce ...
