  • Page 31: Inspect Wood Grain

    Inspect Wood Grain To achieve optimal results, cut WITH the grain. Inspect the wood grain from the side of a workpiece to determine the feed direction. Avoid cutting against/across/end grain as severe kickback and chipping may occur. Some workpieces have complex wood grains and it is impossible to cut with the grain for the entire length of a workpiece.
