    Default 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)

    Default 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.
