Got something else going on...
If I try threading, the half nuts would not stay engaged, they lose
this engamenent in a second or so. If I hold the engagement lever,
they they do stay engaged, but I feel the lever kind of bumping.
What would be the typical cause of this.

First things first. Have you ever cleaned them? I've seen half nuts
pack up with swarf and gummy oil so much that they would not engage
fully. A good cleaning may make them almost as good as new. Or not.

The half nuts on my Wards/Logan were gunked like that . Crud between the
halves blocked them closing all the way . Makes 'em wear faster too .
