Place the 3/4" gouge on the rest with the handle parallel to the bed of
the lathe. Roll the gouge on its edge and swing the handle so that the
grind is perpendicular to the stock with the nose of the tool as the
cutting point.

[Illustration: Fig. 20.]

Force the gouge forward into the wood. As soon as the cut is started,
the handle is lowered and swung to the left; (if cutting the left side
of the concave) at the same time the tool is rolled back toward its
original position. This movement brings the cutting point farther down
on the lip and the grind, resting on the side of the cut, will force the
gouge sidewise and will form one-quarter of the circle. Fig. 21.

[Illustration: Fig. 21.]

This cut is continued from alternate side until the concave is nearly to
size. The cut should be tested with a templet before the finishing cut
is taken.


B-I--6-a. Convex Cuts

Rough out the stock between the beads with a parting tool.

Hold the edge of the gouge on the rest with the handle, parallel to the
bed of the lathe, to make the nose the cutting point.

Swing the handle to the left so that the grind will form a tangent to
