Indexing; Changing Speeds; Spindle Turning - Craftsman 351.217170 Operator's Manual

The rocker switch has a removable key to prevent unautho-
rized use or accidental start-up of the lathe. Removing the key
will lock the lathe from use.
To lock the lathe:
• Turn the speed control knob to OFF position.
• Switch off the rocker switch.
• Disconnect the line cord from power source.
• Pull out the removable key. The key has the words,
"Remove to Lock".
• Store key in a safe place
NOTE: With the key removed, the rocker can be "ROCKED",
but the switch cannot be actuated.
To unlock the lathe:
• Make sure the line cord is disconnected from the power
source, and the speed control knob is in the OFF position.
• Position the rocker in the OFF position.
• Insert the key into the rocker.
• The switch can now be actuated.

CHANGING SPEEDS
To vary spindle speeds, rotate speed control knob to the
desired setting. Always set the knob to the lowest speed
before switching the rocker switch to "ON". Refer to speed
chart for specific turning operations.
SPINDLE TURNING
If you have never done any amount of wood turning, we sug-
gest that you practice using the various wood turning tools.
Start with a small spindle turning.
Be sure to study the following pages of this manual. They
explain and illustrate the correct use of the turning tools, the
positioning of the tool rest, and other information to help you
gain experience.
• Select a piece of wood 2" x 2" x 12".
• Draw diagonal lines on each end to locate the centers.
Diagonal Lines on
Both Ends
Figure 10
• On one end, make a saw cut approximately _/_" deep on
each diagonal line. This is for the spur center.
• The other end uses the bearing center. Place the point of
the bearing center on the wood where the diagonal lines
cross.
• Drive the bearing center into the wood. Use a wooden mal-
let or a plastic hammer, but put a piece of wood on the end
of the bearing center to protect it from harm.
Figure 11
• Remove the bearing center and drive the spur center into
the other end of the wood. Make sure the spurs are in the
saw cuts. Remove the spur center.
• Make sure the centers and the hole in the spindle and the
tailstock ram are clean. Insert the spur center into the
headstock and the bearing center into the tailstock. Tap
them in lightly with a piece of wood. Do not drive them in.
• If the tailstock center is not of the ball bearing type, put a
drop of oil or wax on the wood where it contacts the cen-
ter. This will lubricate the wood while it is turning.
• Place the wood between the centers and lock the tailstock.
• Move the bearing center into the wood by turning the hand
wheel. Make sure that the bearing center and spur center
are "seated" into the wood in the holes made earlier. Rotate
the wood by hand while turning the hand wheel.
• Adjust the tool rest approximately W' away from the cor-
ners of the wood and _/8" above the center line. Note the
angled position of the tool rest base. Lock the tool rest
base and the tool rest.
1/8"
Figure 12 TOOL REST
Observe the speed chart (see page 14). For example, a 2"
square turning up to 18" long should run at 11O0 RPM for
"roughing". Rotate the wood by hand to make sure that the
corners do not strike the tool rest and verify that the index-
ing pin is not engaged.

INDEXING
Refer to Figure 14, 15 and 75, pages 8 and 23.
For all indexing operations, the index wheel must be attached to
armature shaft (Key No. 43). To attach index wheel:
• Loosen three bolts (Key No. 54) and remove protective
cover (Key No. 53).
