Half nuts disengage by themselves
The cleanup of the lathe is basically done all around, the VFD is
wired the way I want and things are cookin'.
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.
