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.
