Saddle Screw Error Adjustment

I "assume" your talking about the cross slide. There are two main places that can cause this. Most of the time the screw and or nut are worn. Check the files for a article by Dennis Turk on the repair of it. Secondly the same author has posted methods of putting  thrust bearings behind the dial to take out play in the whole screw where it goes through the casting.

Subject: [southbendlathe] Saddle Screw Error Adjustment

My saddle screw (sb13) appears to have around .020 of play in it
between the forward and reverse directions. In other words if I turn
it one way until the saddle actually moves and then turn the other way
until the saddle is about to move, the dial has indicated .020 and the
saddle hasn't moved.

Is this something I need to live with, or is there an adjustment that I
missed?

Regards,
Eric
