Place the gouge on edge on the tool rest so that the grind of
the chisel forms an approximate right angle with the work (Fig.
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 forward so that at the end of the cut, Fig. 58, it will be
well up on the work and at an angle 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, you can omit the nicking cut
with skew (Fig. 59). The successive cuts are shown in Figs. 60
and 61. You can perform the final trimming operation (Fig. 62)
with either the skew, spear chisel, or gouge This 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.

FACEPLATE TURNING
Mount turnings that cannot be worked between centers on a faceplate. The greater part of this type of turning is done with the
faceplate mounting, although there are a number of jobs which require special chucks. All cutting in faceplate work is done by
scraping. Any attempt to use a cutting technique on the edge grain of large work will result in a hogging, gouging cut which may jerk
the chisel out of the hands of the operator. Use a band saw on all work to roughly cut the turning area slightly oversized to eliminate
heavy roughing cuts in turning.
