Lathe DRO

I have never had that problem in the 6 or so years I have had my DRO fitted. My lathe is very similar to yours so it should be the same.

I am not sure whats happening to yours, but I would be checking the gibs as if there loose it might be moving from the sudden drive of the lead screw.

Backlash in the cross slide (and any other slide) is not going to make it do that and is a natural thing to have on a lathe. You can adjust it out as much as possible, but it might bind in other places or become loose. It will also wear the nut quicker the tighter you have it.

I am wondering if the gear selector passes the cross slide gear on the way through to engage which makes it move that little bit.

Dave,

It's not the gib. I already checked it. Your last comment about the gear is something else I was thinking it might be. I'll tear down the cross slide and make sure everything it tight and if it still does it then I'll need to dig deeper.

Thanks for the help guys.

Ed
