The cross-slide can be power operated by pulling out the
hand knob (A), at one-third feed per spindle revolution, or it
can be hand-operated using the large-diameter dial grad-
uated in either inch or metric divisions to suit the operating
screw and nut fitted.

7.8 TAIL STOCK
Can be freed for movement along the bed by unlocking the
clamp lever (A). The tailstock barrel is locked by lever (B).
The tailstock can be offset for production of shallow tapers
or for re-alignment. Release the clamping lever (A) and
adjust screws (S) at each side of the base to move tailstock
laterally across the base. An indication of the offset is given
by the datum mark (C) at the tailstock end face, as shown
in Figure 18. Apply clamp lever after adjustment of set-over.

8.0 SERVICING AND MAINTENANCE
8.1 LATHE ALIGNMENT (PART 1)
With the lathe installed and running, we recommend a
beginning check of the machine alignment before work.
Check leveling and machine alignment at regular periods
to ensure continued lathe accuracy.
Headstock check: Take a light cut with a sharp tool over a
6 inch (150 mm) length of a 2 inch diameter (50 mm) steel
bar gripped in the chuck but not supported at the free end.
Micrometer readings at each end of the turned length (See
Figure 22) should be the same.
To correct a difference in readings, loosen the four head-
stock hold-down screws (J) shown in Figure 21 and adjust
the set-over pad (K) beneath the headstock. Then tighten
all screws. After adjustment, repeat the test-cut/microme-
ter reading until micrometer readings are identical so that
machine cutting will be absolutely parallel.

8.2 LATHE ALIGNMENT (PART 2)
B. Tailstock check
Using a 12 inch (305 mm) ground steel bar fitted between
headstock and tailstock centers, check the alignment by
fitting a dial-test indicator to the topslide and traversing the
center line of the bar.
To correct error, release the tailstock clamp lever and
adjust the two set-over screws provided. Continue with
checking and correction until the alignment is perfect.
