Resawing

Resawing is a ripping operation in which thick boards are cut into thinner ones. Narrow boards up to 3" can be resawn in one pass. Wider boards up to 6" must be resawn in two passes.

In resawing wider boards, adjust the blade height so as to overlap the two cuts by 1/2" as shown in Figure 35. Too deep a first cut can result in binding and possible kickbacks on the second cut. Always use the same side of the board against the fence for both cuts.

Crosscutting

Crosscutting is where the workpiece is fed cross grain into the saw blade using the miter gauge to support and position the workpiece (Figure 36).

Figure 36

Crosscutting should never be done freehand nor should the fence be used as an end stop unless an auxiliary block (A, Figure 37) is clamped to the front of the blade area such that the cutoff piece comes free of the block before cutting starts.

Figure 37

Length stops should not be used on the free end of the workpiece in the cutoff area.

Do not crosscut workpieces shorter than 6". Before starting a cut, be sure the miter gauge is securely clamped at the desired angle. Hold the workpiece firmly against the table and back against the miter gauge. Always use the saw guard and riving knife and make sure the riving knife is properly aligned.

For 90 degree crosscutting, most operators prefer to use the left-hand miter gauge slot. When using it in this position, hold the workpiece against the gauge with the left hand and use the right hand to advance the workpiece. When using the right hand slot for miter and compound crosscutting so that the blade tilts away from the gauge, the hand positions are reversed.

When using the miter gauge, the workpiece must be held firmly and advanced smoothly at a slow rate. If the workpiece is not held firmly, it can vibrate causing it to bind on the blade and dull the saw teeth.

Figure 38

To improve the effectiveness of the miter gauge in crosscutting, some users mount an auxiliary wooden extension face (A, Figure 38) with a glued-on strip of sandpaper (B) to the miter gauge.
