Another Acme Thread Question!

Agreed. It looks more like Acme from the latest picture.

If you start by making a backlash adjusting additional nut in brass or delrin (acetal) it can be loose as you like. See if that work for you and only if not go to the added complication route.

Hello,

Any links / threads / pictures that would help me better understand this idea please ?

Bill,

It's a simple concept … Two nuts, each can be a little sloppy-fit on the screw: Then put a spring or an adjuster between them.

To be honest: it's sometimes a bit of a fudge … It only works well if the thread pitch and form are well-matched on all three components [screw and two nuts]
