Cross slide play adjustment? 9C
Hi guys,
I seem to have a bit of play in the feed on the cross slide,
It moves back and forth about 1/4 of a turn b4 engaging.
This isn't a huge problem for me when I am turning as I'm a beginner and don't know any better lol
But when I use a milling attachment it allows the stock to shudder badly.
Is there a way of adjusting the play in the cross slide? or do I have to replace the cross feed screw and nut?
Any Advice is appreciated

Replacing parts is the best fix, but here are some crazy ideas (hacks?):
- Thick grease in the feed screw & nut.
- Clamp the cross slide in position.
(depending on what sort of milling operation you are doing.
You might need to turn the job around) - Put a large spring on the slide.
(say, clamp on the back of the slide, pulling toward the bed,
or in the front, pushing away from the feed handle)

wear
its a very common problem, most older lathes have some wear in the cross feed screw and nut, its usually a bronze nut . The screw wears away at the centre section where its used the most. Replacing the nut only fixes half of the problem. You can buy a length of new cross screw and fit it into the handle , its a ACME thread form from memory . In some cases it is possible to make a new nut from a modern synthetic material, its been written up on various web sites , you use a heat gun and melt the material onto the screw for a perfect fit.
