Delta 46-700 - Square Sections

The gouge is placed on edge on the tool rest in such a
position that the grind of the chisel forms an approximate
right angle with the work, as shown in Figs. 68 and 69.
The chisel contacts the work at the center of the cutting
edge, the tool being held so that the centerline of the
gouge is pointing directly towards the center of the revolv¬
ing stock, as shown in Fig. 70. This starting position is
important; otherwise the gouge will have a tendency to
run along the surface of the work.
From the starting position, the gouge is pushed into the
revolving stock, and the tool is rolled on the rest. A triple
action takes place here: First, the chisel is rolled to follow
the shape of the cut; second, the handle is dropped
slightly so that the portion already cut will force the lip of
the chisel sidewise; third, the chisel is pushed forward so
that at the end of the cut, Fig. 71, it will be well up on the
work and tangent with the cut surface. Only one-half of
the cut is made at one time, then the chisel is reversed
to cut the other half. The occasional turner is advised to
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, the stock should
be jointed 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, one method being
pictured in Figs. 72, 73, 74 and 75. If the parting tool is
sharp, the nicking cut with skew, Fig. 72, can be omitted.
The final trimming operation Fig. 75, can be done with
either the skew or spear chisels. This is a scraping opera¬
tion. While the shoulder can be cut with the same techni¬
que used for cutting a bead, the simpler scraping method
pictured does clean work and is easier to do.
