ROUGHING OUT:
1. Begin with a large roughing gouge. Place the tool on the tool support with the heel of the tool on the surface to
be cut.
2. Slowly and gently raise tool handle until cutting edge comes into contact with the workpiece.
3. Beginning at the tailstock end of the
workpiece, roll the flute (hollowed-out
portion) of the tool in the direction of the
cut, Figure 6. Make long sweeping cuts in a
continuous motion to rough the piece down
to a cylinder. Keep as much of the bevel of
the tool as possible in contact with the
workpiece to ensure control and avoid
catches.
NOTE: Always cut down-hill, or from
large diameter to small diameter. Always
work toward the end of a workpiece,
never start cutting at the end.
4. 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).
5. Add details to the workpiece with skew, parting tool, scraper or spindle gouge.
BEADS:
1. Make a parting cut for what is to be a bead to the desired depth. Place the parting tool on the tool support and
move tool forward to make the full bevel of the tool come in contact with the workpiece. Gently raise handle to make
cut to the appropriate depth.
2. Repeat for other side of the bead.
3. 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 direction of cut.
COVES:
1. Use a spindle gouge. 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,
Figure 7. Stop at the bottom; attempting
to go up the opposite side may cause
the tool to catch.
2. Move the tool over the desired width
of the cove.
3. With the flute facing the opposite
direction, repeat step 1 for other side of
cove. Stop at bottom of cut.
"V" CUTS:
1. Use the long point of the skew.
(NOTE: Do not press the long point of the skew directly into the workpiece to create the "V"; this will result in a
burned or burnished "V" with fibers being rolled up at both sides.)
2. Lightly mark the center of the "V" with the tip of the skew.
3. Move the point of the skew to the right half of the desired width of your cut.
4. With the bevel parallel to the right side of the cut, raise the handle and push the tool in to the desired depth, as
shown in Figure 8.
5. Repeat from the left side. The two cuts should meet at the bottom and leave a clean "V" cut.
6. Additional cuts may be taken to add to either the depth or width of the cut.
