10.5Cutting Techniques

10.5.1 Roughing Out

1.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.

2.Slowly and gently raise tool handle until cutting edge comes into contact with the workpiece.

3.Beginning about 2” from the tailstock end of the workpiece, roll the flute (hollowed-out portion) of the tool in the direction of the cut. See Figure 26. Make long sweeping cuts in a continuous motion to rough the piece down to a cylinder.

4.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 work-piece, never start cutting at the end.

Figure 26

5.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).

6.Add details to the workpiece with skew, parting tool, scraper or spindle gouge.

10.5.2Beads

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 into 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.

10.5.3Coves

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. See Figure 27. Stop at the bottom; attempting to go up the opposite side may cause the tool to catch.

Figure 27

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.

10.5.4"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 28.

Figure 28

5.Repeat from the left side. The two cuts should meet at the bottom and leave a clean "V" cut.
