The alternate position is a palm-down grip (Fig. A12). In this

position, the heel of the hand or the little finger serves as a guide.

The palm-down position is solid and positive – excellent for

roughing or heavy cutting. Most beginners start with the palm-

down grip, switching later to the palm-up position for better

manipulation of the chisel.

USING THE PARTING TOOL

The parting tool is perhaps the easiest turning chisel to handle.

Simply push this scraping tool into the workpiece (Fig. A14).

You will achieve a better cutting action if you hold the handle

low. In many cases, you can hold the tool with one hand while

your other hand holds the calipers in the cutting groove. When

parting tool cuts are deep, make a clearance cut alongside the

first cut (Fig. A15) to prevent burning the tool point.

SQUARING AN END

You can use the parting tool to quickly square an end. The

parting tool is a rough cutter, but you can smooth the cut with a

skew. However, the whole operation can be done with the skew.

In using the skew, make the first nicking cut with the toe of the

skew (Fig. A16). A deep cut here could burn the chisel, so make

a clearance cut by inclining the skew away from the first cut and

pushing the tool into the workpiece. Continue this procedure of

side cut and clearance cut as often as needed.

NOTE: While the skew can be pushed into the wood in any

direction, you must incline the cutting edge a little away from

this plane. If the full cutting edge of skew bears against the cut

surface, the tool will have a tendency to run. See Fig. A17 for

the proper way to make the cut. Push the chisel straight into

the workpiece, and incline the cutting edge away from the cut

surface. Use only the extreme end of the toe for this cut. You

will use this method of skew handling repeatedly in making

shoulders, beads and vee cuts.

SMOOTHING A CYLINDER

To smooth a cylinder, use a large skew chisel. This requires

practice, but experience with this tool is very important. Place

the cutting point near the center of chisel and high on the

workpiece (Fig. A13). Sometimes, in striving for a certain position

in relation to the workpiece, the beginner will often overlook this

all-important point. Raising the handle will increase the depth

of cut while lowering the handle does the opposite. As with the

gouge, you can advance the skew in either direction. The center

of the skew toward the heel does the actual cutting. The back

portion of the grind or bevel supports the tool, while the handle

hand controls the depth of cut by rocking the chisel on this pivot

point. Because of this, keep the skew bevel perfectly flat.
