23Figure 9-69.3 ResawingResawing is a ripping operation in which thickboards are cut into thinner ones. Narrow boards upto 3" can be resawn in one pass. Wider boards upto 6" must be resawn in two passes.In resawing wider boards, adjust the blade heightso as to overlap the two cuts by 1/2" as shown inFigure 9-7. Too deep a first cut can result inbinding and possible kickbacks on the second cut.Always use the same side of the board against thefence for both cuts.Figure 9-79.4 CrosscuttingCrosscutting is where the workpiece is fed crossgrain into the saw blade using the miter gauge tosupport and position the workpiece (Figure 9-8).Crosscutting should never be done freehand norshould the fence be used as an end stop unless anauxiliary block (A, Figure 9-9) is clamped to thefront of the blade area such that the cutoff piececomes free of the block before cutting starts.Figure 9-8Figure 9-9Length stops should not be used on the free end ofthe workpiece in the cutoff area.Do not crosscut workpieces shorter than 6". Beforestarting a cut, be sure the miter gauge is securelyclamped at the desired angle. Hold the workpiecefirmly against the table and back against the mitergauge. Always use the saw guard and riving knifeand make sure the riving knife is properly aligned.For 90-degree crosscutting, most operators preferto use the left-hand miter gauge slot. When using itin this position, hold the workpiece against thegauge with the left hand and use the right hand toadvance the workpiece. When using the right handslot for miter and compound crosscutting so thatthe blade tilts away from the gauge, the handpositions are reversed.When using the miter gauge, the workpiece mustbe held firmly and advanced smoothly at a slowrate. If the workpiece is not held firmly, it canvibrate causing it to bind on the blade and dull thesaw teeth.To improve the effectiveness of the miter gauge incrosscutting, some users mount an auxiliarywooden extension face (A, Figure 9-10) with aglued-on strip of sandpaper (B) to the miter gauge.
