The gouge is placed on edge on the tool rest so that
the grind of the chisel forms an approximate right angle
with the work (Figs. 57). The chisel contacts the work at
the center of the cutting edge. Hold the tool so that the
centerline of the gouge is pointing directly toward the
center of the revolving stock. This starting position is
important to prevent the gouge from running along the
surface of the work.

From the starting position, push the gouge into the
revolving stock, and roll the tool on the rest. A triple
action takes place here. (1) The chisel will roll to follow
the shape of the cut, (2) the handle will drop slightly so
that the portion already cut will force the lip of the
chisel sideways and, (3) the chisel will be pushed for-
ward so that at the end of the cut, Fig. 58, it will be well
up on the work and tangent with the cut surface. Make
only one-half of the cut at a time, then reverse the chisel
to cut the other half. The occasional turner should make
cove cuts with a scraping technique, using either the
small gouge or round nose chisel.

SQUARE SECTIONS

When the turning has a square section, joint the stock
before turning. Good centering is essential since any
error will show at the shoulder where the round meets
the square. Turning of the shoulder from square to

round can be done in various ways. If the parting tool
is sharp, the nicking cut with skew (Fig. 59) can be

omitted. The final trimming operation (Fig. 62) can be
done with either the skew, spear chisel, or gouge, and
is a scraping operation. While the shoulder can be cut
with the same technique used for cutting a bead, the
simpler scraping method pictured does clean work and
is easier to do.
