OPTIONAL TEST RUN PROCEDURE
Run the spindle for a few minutes, forward and reverse, at a
selection of the available 8 speeds.
The carriage feed gearbox should also be run at this time, but
first make certain that the leadscrew and feed shaft oilers at
the tailstock end have been lubricated.
Also note:
In initial tests, because the saddle and cross slide
should first be exercised manually, the leadscrew split-nut
should be disengaged — ditto the saddle/cross-slide power
feed lever, Figure 1-9. The power feed lever can be either in or
out, but it should be centered, neither up nor down.
ALIGNING THE LATHE
The most important attribute of a properly set up lathe is its
ability to “machine parallel”, to cut a cylinder of uniform diam-
eter over its entire length. In other words, no taper.
Leveling of the lathe is a part of this, see earlier in this section.
Equally important is the alignment of the center-to-center axis
with the lathe bed, as seen from above . [Vertical alignment is
nowhere near as critical, rarely causing taper unless the lathe
is damaged or badly worn.] For more information see the final
pages of Section 4, Servicing the Lathe.
After the initial test run, perhaps with a few additional hours of
machine time, some users drain and refill the headstock and
carriage feed gearbox. Lubricants are specified in Section 4.
Other users prefer to delay this service action for at least 50
hours of running time. No specific recommendation is given by
Precision Matthews.
