8.4Cam tightness

The clamping mechanisms of headstock, tailstock and tool rest base are pre-set by the manufacturer, and should not require adjustment.

If one of them does not tighten properly against the bed when the locking handle is tightened, adjust it as follows. (Figure 11 uses the tailstock as the example.)

Figure 11

1.Remove stud from end of lathe bed, and slide tailstock off.

2.Turn tailstock on its side, and tighten lock nut (F, Figure 11) to increase cam pressure, or loosen the nut to relieve cam pressure.

3.Mount tailstock on bed and lock it to verify adjustment. Repeat as needed.

4.Reinstall stud.

8.5Tool rest

A 12-inch tool rest is provided with your lathe. It is designed to allow adjustment for height, position on the bed, and angle to the work.

Loosen locking handle on tool rest base (G, Figure

12)to slide base forward or back, and to angle it to the bed. Tighten locking handle firmly before operating lathe.

Loosen handle (H, Figure 12) to raise or lower tool rest and angle it to the work. Tighten handle before operating lathe.

Figure 12

8.6Tool rest extension

The extension (J, Figure 13) mounts to the tool rest base and offers greater reach for the tool rest when turning off the bed using the headstock at an angle, as shown.

Make sure the clamp bushings (K, Figure 13) are pulled apart sufficiently to accept the post of the extension.

8.7Locking handles

Locking handles, such as H, Figure 12, are adjustable. Simply lift out on handle, rotate it on the pin, then release it, making sure it seats itself on the pin.

8.8Spindle indexing

Indexing is used to create evenly spaced features in a work piece, while keeping the lathe spindle locked; for example, when cutting flutes on a spindle blank with a hand-held router, while the spindle blank is secured between lathe centers.

The JWL-1440VS lathe provides 36 indexing positions. These are identified in the chart in section 15.0.

Figure 14

1.Rotate spindle using the handwheel until the index pin (L, Figure 14) aligns with the desired hole.

2.Screw the index pin into the hole until it engages the spindle.
