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.
