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.
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.
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.
