Here is a lead screw and AB nut a machined for the use on a Z axis. I used threaded rod and coupling nuts and a length of 1 ID DOM tube. The coupling nuts were machined for a close fit in the DOM tube and the threaded rod was machined for 6001R2 bearings at each end. And at the top end it was turned for a 3/8 ID belt pulley.
The threaded rod and coupling nuts were assembled in the DOM tube and one nut was spot welded to the tube. The un-welded coupling nut was adjusted so no end play was achieved and the setscrews were installed and tightened (this may take a few tries to get it working just right). Shown are two DIY bearing blocks for ends of the threaded rod. If more info is wanted PM me. I did not think these up I got the idea from BuildYourIdea.com (http://www.buildyouridea.com/) I just changed it little
Have fun

Great work Tom. No whipping on that rod. I like the free play adjustment too.
