Rift-sawing may also be described as lumber produced during latter stages of stepped cuts on a quarter round, where the subsequent cuts are parallel to either of the initial quartering cuts. The AWI defines "rift sawing" as a technique of cutting boards from logs so the grain is between 30–60° to the face of the board, with 45 degrees being ...
The relative angle that form the rings and the surface go from almost zero degrees in the external planks to almost ninety degrees at the core of the log. Quarter sawing gets its name from the fact that the log is first quartered lengthwise, resulting in wedges with a right angle ending at approximately the center of the original log.
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.
With the "rip" tooth pattern, the edges are sharpened at right angles to the cutting plane, forming chisel-like cutting surfaces, whereas crosscut teeth are sharpened at an angle, so that each tooth has a knife-like cutting point in contact with the wood. [1]
A variation is a base shoe, a quarter of an ellipse. [1] Most quarter round is of small gauge and relatively flexible. It is typically used as a decorative build-up element in mantels and other architectural features, and at the lower edge of baseboard to hide any gaps between it and a floor. Base shoe is used similarly in flooring applications.
