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. 39).
This position will give a clean shearing cut. When
pushed straight into the work (Fig. 36), the gouge
has a scraping action, (normally a poor practice in
spindle turning). The roughing cut is continued 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 between 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 tool 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.
37) is generally considered best. In this position, the
first finger acts as a guide, sliding along the tool rest as
the cut is made.
The alternate position is a palm-down grip (Fig. 38). In
this position, the heel of the hand or the little 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.
