Place the gouge on the edge of the tool rest so that the
grind of the chisel forms an approximate right angle with
the workpiece (Fig. A33). Allow the chisel to contact the
workpiece 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 workpiece.
From the starting position, push the gouge into the workpiece
and roll the tool on the rest. A triple action takes place here.
(1) Roll the chisel to follow the shape of the cut, (2) drop the
handle slightly so that the portion already cut will force the
lip of the chisel sideways and, (3) push the chisel forward so
that at the end of the cut (Fig. A34), the chisel will be well up
on the workpiece 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. You can
turn the shoulder from square to round in various ways (See
Figs. 59, 60, 61, and 62). If the parting tool is sharp, you
can omit the nicking cut with the skew (Fig. 61). Do the final
trimming operation (Fig. 62) with either the skew, spear chisel,
or gouge. Make this a scraping operation. While you can cut
the shoulder 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.
