Mounting the Work
Move the tailstock to approximately 1 to 1-1/2"
from the end of the work piece and lock in
position. Turn the tailstock handwheel until the
center makes contact with the work piece.
Continue to turn the hand wheel and slowly
rotate the work piece by hand. After the work
piece becomes difficult to turn by hand, reverse
the hand wheel approximately one quarter turn
and lock the tailstock spindle (Figure 10).
Adjusting the Tool Rest
Position the tool rest approximately 1/8" away
from the work piece and 1/8" above the work
centerline. After some experience has been
gained, this position can be varied slightly to suit
the operation.
Position of Hands
There is no "proper" position for the hands when
using chisels. Most beginners begin by using the
palm-down grip (Figure 11) for better control and
switch later to the palm-up position (Figure 12)
for better manipulation. In the palm-down
position, the little finger or heel of the hand acts
as a guide along the tool rest. The first finger
acts as a guide when using the palm-up method.
Roughing a Cylinder
Use a large gouge and run the lathe at a slow
speed to rough-off the sharp corners of the
work. Begin the cut 2 to 3 inches from the
tailstock and work toward and off the tailstock
end. Continue by cutting the next 2 to 3 inches
left of the first cut, preferably working toward the
tailstock end. This method of always working
toward the tailstock is preferred because it
throws the chips clear of the operator. Do not
rough cut by taking one long pass at the work
piece and do not start cuts at either end of the
work piece. This has a tendency to tear long
slivers from the work piece. Roll the gouge over
slightly in the direction of the cut for best results.
Once a cylindrical form has started to take
shape, step up the speed one or two stops.
Smoothing a Cylinder
Use a large skew chisel with the cutting point
near the center of the chisel and high up on the
work piece. Support the chisel on the tool rest at
all times. To locate the proper cutting position,
place the chisel flat against the work piece with
the skew well over the area to be cut. Pull back
slowly on the chisel until it bites into the wood.
Raising the handle will increase the depth of cut;
lowering the handle will decrease the depth of
cut.
