Chisel Parallel to Workpiece

Referring to Figure 16:

The chisel can be adjusted parallel to the workpiece as follows:

1.With the left handwheel (A), move the table back far enough to insert the workpiece (B) between the chisel (D) and fence.

2.Loosen the lock screw (C). This will allow the chisel to rotate.

3.Bring the table forward with the handwheel

(A)until the workpiece (B) rests against the back surface of the chisel (D), but do not force.

Further adjust the chisel by hand if needed.

4. Tighten the lock screw (C).

Operation

1.Set the depth stop (A, Fig. 17) to the required depth of cut. Refer to the Depth Stop Rod Adjustment section.

5.Place workpiece on table (C, Fig. 18) and clamp it with the vise (A, Fig. 18). Use the left handwheel (D, Fig. 18) to move table forward or backward to suit the position of the mortise on the workpiece.

6.Adjust the table stops according to the length of cut required, then tighten the thumbscrews (B, Fig. 18).

Before turning the machine on, verify that the chuck key is not in the chuck.

7.Turn on the machine and feed the chisel and bit steadily into workpiece by pulling down the operating handle.

Note: The rate of feed must be fast enough to prevent burning at the tip of the bit, but not so fast as to cause the machine to slow or stall. The different rates of feed for different woods must be learned through experience.

8.After the first cut, the workpiece is moved along with the right handwheel (E. Fig. 18) for each successive cut. The direction of movement must allow the chips to clear freely. Move the workpiece so that the slot in the chisel is releasing chips into the already cut part of the workpiece (Figure 19).
