Direction of Grain Avoid feeding work into the jointer against the grain. This will result in chipped and splintered edges (Figure 27). Feed with the grain to obtain a smooth surface (Figure 28). Hand Placement At the start of the cut, the left hand holds the Figure 27 work firmly against the infeed table and fence while the right hand pushes the work toward the knives. After the cut is under way, the new surface rests firmly on the outfeed table. The left hand should press down on

Edge Jointing This is the most common operation for the jointer. Set guide fence square with the table. Depth of cut should be the minimum required to obtain a straight edge. Do not make cuts deeper than 1/8" in a single pass. Hold the best face of the piece firmly against the fence throughout the feed. See Figure 30. When edging stock wider than 3 inches, lap the fingers over the top of the wood, extending them back over the fence so that the fence casting will act as a stop for the
