Figure 7-4: cam adjustment
1. Remove stud from end of lathe bed, and slide
tailstock off.
2. Turn tailstock on its side, and tighten lock nut
(F, Figure 7-4) 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.
7.5 Tool rest
See Figure 7-5.
A 14-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
7-5) to slide base forward or back, and to angle it
to the bed. Tighten locking handle firmly before
operating lathe.
Loosen handle (H) to raise or lower tool rest and
angle it to the work. Tighten handle before
operating lathe.

7.6 Tool rest extension
See Figure 7-6.
The extension (J, Figure 7-6) 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.
Make sure the clamp bushings (K) are pulled apart
sufficiently to accept tool rest post.

7.7 Locking handles
Locking handles, such as H, Figure 7-5, are
adjustable. Simply lift out on handle, rotate it on the
pin, then release it, making sure it seats itself on
the pin.
7.8 Spindle indexing
See Figure 7-7.
Indexing is used to create evenly spaced features
in a workpiece, 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-1840EVS lathe provides 36 indexing
positions at 10-degree increments.
1. Rotate spindle using handwheel until index pin
(L, Figure 7-7) aligns with desired hole.
2. Screw index pin into hole until it engages
spindle.
3. Perform desired procedure.
4. Unscrew index pin until spindle is released.
Rotate spindle to next desired hole, and
repeat.
Disengage index pin before
starting lathe.
IMPORTANT: Do not use index pin to lock spindle,
which will cause unnecessary wear to the pin. Use
spindle lock for this purpose.
