INTERNAL BORING

In roughing out the center for Napkin Rings, Jewel Boxes, etc., the
quickest method is to work it out with a small gouge.

Place the gouge on the rest parallel to the bed of the lathe, having the
point even with the center of the stock.

Force the gouge into the wood until a hole is bored to the depth
required. If the hole is deeper than 1", remove the tool often and clear
out the shavings in order not to burn the point.

In order to enlarge the hole to the proper size the point of the gouge
is pressed against the left side of the hole a little above the center
and a shearing cut is taken. To obviate the danger of the tool catching,
all cuts should start from the back of the hole and proceed toward the
front.

B-III--8-a. Sphere

After the sphere is turned as nearly perfect as is possible when working
between centers (Steps 1 to 4) it is cut free from the waste stock and
is centered in a chuck.

The chuck is made of any soft wood and should be cut in the end grain,
which will insure equal pressure on all sides. Equal pressure cannot be
obtained if the Chuck is cut in cross grain wood, owing to the tendency
