OPERATION
CUTTING TECHNIQUES
Begin with a large roughing gouge. Place the tool
on the tool rest with the heel of the tool on the
surface to be cut. Slowly and gently raise the tool
handle until the cutting edge comes into contact
with the workpiece. Beginning about 2 inches from
the tailstock end of the workpiece, roll the flute of
the tool (the hollowed-out portion) in the direction
of the cut. Make long sweeping cuts in a continuous
motion to turn the piece to a cylinder (Fig. 22).
Keep as much of the bevel of the tool in contact
with the workpiece as possible to ensure control
and avoid catches.

Once the workpiece is roughed down to a cylinder, smooth it with a large skew. Keep the skew handle
perpendicular to the spindle and use only the center third of the cutting edge for a long smoothing
cut (touching one of the points of the skew to the spinning workpiece may cause a catch and ruin the
workpiece). Add details to the workpiece with skews, parting tools, scrapers or spindle gouges.
BEADS
- Make a parting cut for what is to be a bead to the desired depth. Place the parting tool on
the tool rest and move the tool forward to make the full bevel of the tool come into contact with the
workpiece. Gently raise the handle to make cuts of the appropriate depth. Repeat for the other side
of the bead. Using a small skew or spindle gouge, start in the center between the two cuts and cut
down each side to form the bead. Roll the tool in the direction of the cut.
COVES
(Fig. 23) - Use a spindle gouge to create a cove. With the flute of the tool at 90 degrees to the
workpiece, touch the point of the tool to the workpiece and roll in towards the bottom of the cove.
Stop at the bottom, as attempting to go up the opposite side may cause the tool to catch. Move the
tool over the desired width of the cove. With the flute facing the opposite direction, repeat the step
for the other side of the cove. Stop at the bottom of the cut.
V-GROOVES
(Fig. 24) - Use the point of the skew to create a V-groove in the workpiece. Lightly mark
the center of the V with the top of the skew. Move the point of the skew to the right half of the de-
sired width of your cut. With the bevel parallel to the right side of the cut, raise the handle and push
the tool in to the desired depth. Repeat from the left side. The two cuts should meet at the bottom
and leave a clean V-groove. Additional cuts may be taken to add to either the depth or the width of
the cut.
PARTING OFF
- Adjust the lathe to a slower speed for parting through a workpiece. Place a parting
tool on the tool rest and raise the handle until is starts to cut. Continue cutting towards the center of
the workpiece. Loosely hold on to the piece in one hand as it separates from the waste wood.
NOTE:
Always cut downhill, or from the large
diameter to the small diameter. Always work
towards the end of the workpiece; never start at
the cutting end.
