Step 3:

Make one cut with the reference point on high point of cutting circle.

Begin the eut when the referme« line on the board 1$ directly over the end of the outfeed table. Mark the fence to indicate this point

shown in Fig. 1, Step 1. This third line provides an important reference point for starting the cut.

Now you're ready to go. Switch on the jointer, position the reference point over the end of the outfeed table nearest the cutterhcad (vou've already drawn a line on the fence to mark this point) and lower the board onto the spinning cutterhead as shown in Fig. 1. Step 2. To do this safely, begin with the entire board resting on the infeed table. Hold the board snugly against the fence. Lift the wide end up off the infeed table slightly. Keep the narrow end of the taper resting solidly on the infeed table and slide the board along the fence until the front end nudges the guard aside as shown in the photo. Try this maneuver several times with the power off to get the hang of it.

After six such passes, the board will have a taper but it will also have a slight flat, and a slight snipe near the wide end as show n in Fig. 1. Step 2. To remove both the flat and the snipe you need to make a seventh pass that's slightly different from the first six. Instead of lowering the reference point onto the end of the outfeed table, begin the cut by lowering the reference point directly over the top of the cutting circle as shown in Fig. 1, Step 3. Move the board across the cutterhead as you normally would.

The eighth and final pass is a cut along the entire length of the board as if you were jointing a straight edge as shown in Fig. 1. Step 4.

Partial Tapers

In many cases, you'll want to start a taper several inches from one end of the stock. Table legs, for example. often have a taper that starts just below the apron, a few inches from the top of the leg. The technique is the same as the full-taper technique explained above.

Mark the jointer table as explained for a full taper. On the side of the stock, lay out the taper and the guideline parallel to it and mark the reference point. Make all eight cuts as shown in Fig. 1. The untapered section at the top of the leg simply goes along for the ride. It touches neither the blade nor the outfeed table.

Short Tapers

Short tapers on the end of a long piece present a special problem. The taper must be long enough to span both tables. If the taper is too short, the stock can drop into the cutterhead—an extremely dangerous situation. Make sure the taper you plan to joint is longer than the gap between the infeed and outfeed tables. If you want a taper that's shorter than the gap between the tables, begin with a leg that is a little long; joint a taper that's a little longer than desired, then trim the leg (and the taper) to the desired length.

Unlike full or partial tapers, short tapers arc cut in a single pass. Your layout line detenuines the depth-of-cut. Begin by drawing the taper on the stock as shown in Fig. 2, Step 1. At the narrow end of the stock, mea-
