from the center of the stock toward and off either end once the first roughing cuts have been
made. The position of the gouge involves two or three important angles. (1) The tool may be
advanced along the work either from right to left or from left to right. Left to right (from
headstock to tailstock) is preferred since this action throws chips clear of the operator. (2)
The gouge is rolled over slightly in the same direction it is advancing. (3) The tool is held well
up on the work, with the bevel or grind tangent to the revolving surface (Fig. 19). This posi-
tion will give a clean shearing cut. When pushed straight into the work (Fig. 19), the gouge
has a scraping action, (normally a poor practice in spindle turning). The roughing cut is con-
tinued until the work approaches 1/8" of the required diameter. Once a cylindrical form has
been obtained, the turning speed can be moved to the second or third speed setting. NOTE:
Continue to move the tool rest inward toward the work piece to keep the safe distance be-
tween the two.

POSITION OF HANDS
While turning, the hand that holds the tool handle should be in a natural position. This hand
provides the leverage for the too l by either moving in toward the chisel or moving out. The
position of the tool rest hand is more a matter of individual preference, rather than a "set" or
"proper" position. However, a palm-up grip (Fig. 20) is generally considered best. In this po-
sition, the first finger acts as a guide, sliding along the tool rest as the cut is made. The al-
ternate position is a palm-down grip (Fig. 21). In this position, the heel of the hand or the lit-
tle finger serves as a guide. The palm-down position is solid and positive – excellent for
roughing or heavy cutting. Most beginners start with the palm-down grip, switching later to
the palm-up position for better manipulation of the chisel.

SMOOTHING A CYLINDER
To smooth a cylinder, use a large skew chisel. This requires practice, but experience with this
tool is very important. Place the cutting point near the center of chisel and high on the work
(Fig. 22). Sometimes, in striving for a certain position in relation to the work, the beginner
will often overlook this all-important point. Raising the handle will increase the depth of cut
while lowering the handle, of course, does the opposite. As with the gouge, the skew can be
advanced in either direction. The center of the skew toward the heel does the actual cutting.
The back portion of the grind or bevel supports the tool, while the handle-hand controls the
depth of cut by rocking the chisel on this pivot point. Because of this, keep the skew bevel
perfectly flat.
