Figure 21 – Improper setups
13.1 Tool setup
The cutting angle is correct when the cutting edge
is in line with the center axis of workpiece. Use the
point of the tailstock center as a gauge and shims
under the tool to obtain correct center height.
Use a minimum of two clamping screws to secure
each tool.
13.2 Feed and thread selection
1. Reference the feed and thread chart (A, Figure
22).
2. Move levers and knobs (B/C/D/E, Figure 22) to
the appropriate position according to the feed
and thread chart.
Figure 22
13.3 Thread cutting
1. Set forward/reverse lever (F, Figure 22) to
desired direction.
2. Set selector levers (G/H, Figure 22) to desired
R.P.M.
3. Select desired thread using levers (B/C/D/E,
Figure 22).
4. Set selector lever (A, Figure 23) to correct
position (neutral).
5. Engage the half nut lever (B, Figure 23).
6. Make a test cut with scrap material and check
results before cutting regular material.

14.0 Adjustments
Adjustments to the lathe,
especially those involving alignments of
bearings, spindle, leadscrew, clutch, etc.,
should only be performed by qualified
personnel, as improper alignments can damage
the machine and/or create a safety hazard.
Turn off main switch and press
emergency stop button before making
adjustments to lathe.
14.1 Chuck jaw reversal
The three jaws on the scroll chuck are reversible,
to hold stock with larger diameters. See Figure 24.
Loosen two screws with the provided hex key,
remove jaw, and rotate it 180-degrees. Re-install
jaw, and tighten each screw in increments until fully
tightened.
