8.4 Index pin
Refer to Figure 8-6.
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.
Your lathe provides 24 indexing positions. These
are identified by inscribed numbers on the spindle
pulley (H, Figure 8-6)
Figure 8-6
1. Rotate spindle until index pin (J) aligns with
desired hole.
2. Push index pin into hole and rotate knurled
head (J
1
) to engage threads and secure in
position.
3. Perform operation.
4. Rotate knurled head counterclockwise until pin
releases. Move pulley to next desired hole,
and repeat. NOTE: A 3mm hex key (K, Figure
8-6) can be inserted and turned in the hole of
the knurled head, to help tighten or loosen the
index pin.
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 that purpose.
9.0 Operating controls
See Figure 9-1.
On/off switch : Pull up to start lathe, push down to
stop.
To prevent unauthorized use of lathe, turn it off and
pull out the safety key (A). Store key in a safe
place, inaccessible to children. Key must be
reinserted to start lathe.

10.0 Operation
The information which follows is general in nature
and not intended to be a complete course in
woodturning. Nothing can replace the knowledge
gained by conversation with experienced
woodturners, or consulting books or trade articles.
Above all, simple trial and error will aid in
developing proficiency in the craft.
10.1 Inspection
Before operating the lathe, check that everything is
in proper working order:
1. Machine is on a level surface.
2. Check bearings; adjust only if endplay exists.
3. Check belt; it should be snug but not overly
tight.
4. Bed ways; keep clean, use steel wool to
remove any rust spots, and apply paste wax to
prevent buildup of rust and finishes.
5. Tool support; use a mill file to remove nicks
and dings.
6. Spindle tapers; should be clean and free of
dust and chips for proper seating of tapers.
7. Tailstock; clean and lubricate quill and locking
device.
8. Lighting; proper lighting is essential to
eliminate shadows and reduce eye strain.
10.2 Turning Tools
If possible, select only quality, high-speed steel
turning tools. High-speed steel tools hold an edge
and last longer than ordinary carbon steel. As one
becomes proficient in turning, a variety of specialty
tools for specific applications can be acquired. The
following tools provide the basics for most
woodturning projects (see Figure 10-1):
