The cross slide backlash is adjusted by loosening 
all four cap screws shown in Figure 115, then 
tightening the center set screw. This will push 
down on a wedge and force the leadscrew nut 
apart, taking up lash between the nut and 
leadscrew.

Backlash Adjustment
Backlash is the amount of free play felt while 
changing rotation directions with the handwheel. 
This can be adjusted on the compound rest 
and cross slide leadscrews. Before beginning 
any adjustment, make sure that all associated 
components have been cleaned and lubricated.
Compound Rest
Tools Needed: 
Qty
Hex Wrench 3mm ................................................. 1
The compound rest backlash is adjusted by 
tightening the set screws shown in Figure 
114
. When these screws are adjusted against 
the leadscrew nut, they offset part of the nut to 
remove play between the nut and leadscrew.

Set Screws
Reducing backlash to less than 0.002" is 
impractical and can lead to accelerated wear 
of the wedge, nut, and leadscrew. Avoid the 
temptation to overtighten the backlash set 
screw while adjusting. 
To adjust the backlash, rock the handwheel back 
and forth, and tighten the screws slowly until 
the backlash is approximately 0.002"–0.003", as 
indicated on the graduated dial.
If you end up adjusting the nut too tight, loosen 
the set screws, tap the compound rest a few 
times with a rubber or wooden mallet, and turn 
the handwheel slowly back and forth until it 
moves freely—then try again.

If you end up adjusting the nut too tight, loosen 
the set screw, tap the cross slide a few times 
with a rubber or wooden mallet, and turn the 
handwheel slowly back and forth, until the 
handle turns freely—then try again.
Remember to re-tighten the four cap screws 
when you are finished.
