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 work (Fig. 38). Sometimes, in striv-

ing for a certain position in relation to the work, the

beginner will often overlook this all-important point.

Raising the handle will increase the depth of cut while

lowering the handle, of course, does the opposite. As

with the gouge, the skew can be advanced 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 work Fig.

39. A somewhat better cutting action is obtained if the

handle is held low. This tool is, in many cases, held with

one hand while the other hand holds the calipers in

the cutting groove. When parting tool cuts are deep, a

clearance cut should be made alongside the first cut

(Fig. 40) to prevent burning the tool point.

SQUARING AN END

The parting tool can be used to quickly square an end.

Since the parting tool is a rough cutter, the cut can then

be smoothed by the use the skew. However, the whole

operation can be done with the skew. In using the skew,

make your first cut a nicking cut with the toe of the skew

(Fig. 41). A deep cut here could burn the chisel, so

a clearance cut is made by inclining the skew away from

the first cut and pushing the tool into the work. This

procedure of side cut and clearance cut is continued as

often as needed. NOTE: While the skew can be pushed

into the wood in any direction, the cutting edge itself

must be inclined 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. 42 for the

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

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

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

This important principle in skew handling will be used

repeatedly in making shoulders, beads and vee cuts.
