Resawing

1.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.

2.In resawing wider boards, adjust the blade height so as to overlap the two cuts by 1/2" (Figure 40). Too deep a first cut can result in binding and kickbacks on the second cut. Always use the same side of the board against the fence for both cuts.

Crosscutting

1.Crosscutting is a sawing process where the workpiece is fed cross grain into the saw blade using the miter gauge to support and position the workpiece.

Do not crosscut workpieces shorter than 6".

2.Before starting a cut, be sure that the miter gauge is securely clamped at the desired angle. Hold the workpiece firmly against the table and back against the miter gauge as shown in Figure 41. Always use the saw guard and splitter and make sure the splitter is properly aligned.

3.Crosscutting should never be done freehand nor should the fence be used as an end stop unless an auxiliary block is clamped to the front of the blade area such that the cutoff piece comes free of the block before cutting starts (Figure 42). Length stops should not be used on the free end of the workpiece in the cutoff area.

4.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 crosscutting using the right hand slot, the hand positions are reversed.

5.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.

6.To improve the effectiveness of the miter gauge in crosscutting, some users mount an auxiliary wooden extension face with a glued-on strip of sandpaper to the gauge (Figure 43).
