2.Tighten the locking hex nut a 1/4 turn at a time until the tailstock will not move when locked. Repeat this step as necessary.

Cross Slide

Backlash

Backlash is the amount of play in the handwheel, felt when turning the handwheel, but before the slide begins to move.

Note: When adjusting backlash, keep in mind the goal is to tighten the cross slide leadscrew without causing it to bind. Overtightening will cause exces- sive wear to the sliding block and leadscrew.

To adjust the cross slide backlash:

1.DISCONNECT LATHE FROM POWER!

2.Remove the rear splash pan from the lathe.

3.From the rear of the cross slide, loosen/ tighten the two Phillips head screws shown in Figure 99 until you are satisfied with the amount of backlash.
