Cross Slide Backlash
Backlash is the amount of play found in a lead screw.
It can be found by turning the cross slide handwheel
in one direction, and then turning the handwheel the
other direction. When the cross slide begins to move, the
backlash has been taken up.

Backlash is adjusted by tightening or loosening the screw
shown in Figure 44. This screw draws a wedge-type nut
against the lead screw and main nut. If you get it too
tight, loosen the screw a few turns and tap the cross feed
a few times with a rubber or wooden mallet. Then turn
the handle slowly back-and-forth until the handle turns
freely. To readjust the backlash, rock the handle back-
and-forth and tighten the screw slowly until the backlash
is at approximately 0.001" to 0.005" as indicated on the
handwheel dial.

Cross-Slide and Saddle-
Gib Adjustments
When adjusting these gibs (Figure 45), keep in mind
that the goal is to remove sloppiness in the ways without
causing the slides to bind. Loose gibs will cause a poor
finish on the workpiece and may cause undue wear on the
slide. Over-tightening may cause premature wear on the
slide, lead screw, and half-nut.

The cross slide gib is a tapered piece of iron. When you
loosen the three jam nuts and tighten the three set
screws, the screws force the tapered gib to fill the loose
void in the way, thus tightening the play in the cross
slide. If more play is needed turn the screws the other
direction.

For the saddle adjustment, remove the saddle clamp shoe
(Figure 45), and adjust saddle clamp shoe set screw and
reinstall the clamp shoe. Trial and error of this process
will allow for proper saddle-to-way adjustment.
