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.
13.1
Chuck jaw reversal
The three jaws on the scroll chuck are reversible,
to hold stock with larger diameters. See Figure 29.
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.
Figure 29 – Chuck jaw reversal
13.2
Gib adjustments
After a period of time, some moving components
may need adjustment for play (or “backlash”) due
to wear.
Do not overtighten gib screws as this can
hasten wear to components.
Saddle
– Turn screws on either side of saddle at
the rear to adjust drag on saddle.
Cross Slide
– Gib screws are located at front and
rear of slide opposite to one another (A, Figure 30).
To adjust drag, loosen rear gib screw one turn, and
tighten front gib screw a quarter turn. Rotate
handwheel to check play. Repeat as needed until
slide moves freely without play. Gently tighten rear
gib screw.
Figure 30 – Gib adjustments, slide and rest
Compound Rest
– Gib screws are located at front
and rear of compound rest (B, Figure 30). To
adjust, use same method as for Cross Slide.
Half Nut
– Gib screws are located on right side of
apron (C, Figure 31). Loosen the jam nuts and
rotate the screws clockwise until any backlash is
corrected. Then retighten nuts.
Figure 31 – Half Nut gib adjustment
13.3
Tailstock adjustments
The tailstock can be offset to cut shallow tapers up
to 5° angle. See Figure 32.
1. Loosen tailstock in position by lowering locking
handle (D).
2. Alternately loosen and tighten front and rear
screws (E). [Only front screw shown.]
The scale (F) on the end of the tailstock indicates
amount of offset, and helps when re-centering.
If the clamping force needs to be adjusted, use the
hex nut beneath the tailstock body.
