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).
