I might try making a nut from aluminum as practice and see if I can just make new nuts for the existing lead screws.

Sorry Ed, I just thought that a cheap crummy steel "stock|" acme threaded rod might wear faster than a higher grade "precision" lead screw. The fact that the screws on your mill haven't worn (as you mentioned) may prove you right.

OK, got it.
I wasn't planning on getting some cheap crummy steel acme threaded rod. I would go with some of this stuff.
