About 1/2 turn (60 thou) backlash on a Sheldon I've just brought "online".
The screw shows light/reasonable wear on visual inspection, and backlash is about the same even at the far end of travel where there would be zero wear; so the bulk is in the nut.
Machine a new bronze nut? No acme threading tooling or tap, easily solved. Delrin? Even seen this "melted" around an unworn section of screw after boring to correct ID as alternative to machining.
Moglice? Perhaps impractical for such a small job (my guess is I'd have to buy far more than needed for such a small job and I'm sure it ain't cheap). But time is money, and the far end of the screw (integral taper attachment) never sees the nut so it is unworn and perfect to "cast".
I've also heard of using solder inside the nut threads to reduce backlash.
What's the fastest/easiest route here?
