You only leave a gap on the left hand side, the tension end. On the right you want the 12mm nut to grip the angular bearing inner ring against the step in the screw. That gives you something to tighten the nut against so it stays where you put it. Don't want that right end nut free to unscrew itself.

The gap on the left only needs to be long enough to stop the 16mm part of the screw ever touching the bearing. If it does touch then the Belleville washers stop pulling on the screw.

A tiny update to X-axis screw.

It is comforting if the extension carries any motor heat in to the bed, so the screw doesn't warm up.

Will take a note of that. Again really good suggestions. Thanks!

Project has been moving at a snail's pace, but that is okay, have already avoided many pitfalls.
