ADJUSTING TAILSTOCK
Refer to Figure 56.
• Loosen locking lever (Key No. 57) and slide tailstock to
desired position. Tighten lever.
• To adjust quill in or out, loosen locking handle (Key No.
60). Turn handwheel (Key No. 62) until quill is in desired
position and secure in position by tightening locking
handle.
SPINDLE TURNING
If you have never done any amount of wood turning, we
suggest 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 17
• On one end, make a saw cut approximately 1/16 tt 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
mallet or a plastic hammer, but put a piece of wood on
the end of the bearing center to protect it from harm.
Figure 19
Adjust the tool rest approximately 1/aft a way from the
corners of the wood and 1/8"above the center line. Note
the angled position of the tool rest base. Lock the tool
rest base and the tool rest.
l/stY
oo,
• Observe the speed chart below. Move the V-belt on the
pulleys to the slowest speed. Rotate the wood by hand
to make sure that the corners do not strike the tool rest.

INDEXING
Refer to Figure 20.
The index ring has 12 equally spaced holes (30° apart).The index
pin engages with one of the 12 holes and locks the spindle from
turning while you put a mark on the workpiece.
Index Hole
Reference
Figure 18
• 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
center. 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.
Figure 20
For example, to locate the position of six flutes on a cylinder:
• Pull up index pin knob. Twist knob one half turn so that pin
drops into hole of index ring. The pin will engage in the
closest hole available.
• Adjust the tool rest to the centerline of the workpiece and
make a mark.
• Pull up to release index pin. Slowly rotate the workpiece
until pin is located 60 ° (2 holes) from initial position.
Engage index pin into the index ring and place another
mark on the workpiece.
• Continue these steps until there are 6 marks on the work-
piece.
• To disengage index pin knob, pull knob up from engaged
position and twist knob one half turn.
• Bowl turnings or wheel turnings can be marked in the
same manner.
WARNING: The indexing pin must be disengaged for all
other operations on the lathe.
