The moglice sales guy showed us a rather large ball nut, maybe 1.5" dia
screw. He said they had once screwed one up by not using enough release
agent and had to press the rod out. He claimed it took something like
12tons of force to break it out.

But then, I have very little need for a 'very large' mill of any sort.
