With a 10 TPI thread, you have barely 2-1/2 threads in that "adjustment" section. Most nuts like that I'd seen split in the middle so the halves wear evenly. I would also split it through the entire thread. Where is the adjuster on the original and how would you feel about having a cone point set screw coming through the cross slide casting instead of the hard-to-reach position of the original?
Also, how about radii on the upper corners as the original has? I've got corner rounding cutters, so it's easy.
Ken,
Slitting in the middle is no problem. I don't think the way the current nut is slit is a very good design because the slit only goes half way into the thread.
The adjuster is on the end of the nut facing the rear of the lathe. It's kind of hard to get to but not impossible. I don't have a problem with putting a set screw through the cross slide as long as it doesn't land in the spot where I took out that knurled bushing. I'm not visualizing how it would work though. Can you post a quick sketch as to how it would adjust the slit?
Radii on the upper corners would be nice.
By the way, while I was laying in bed last night trying to get to sleep, I realized I measured the center height improperly so a new drawing will be coming.

Sorry about the crummy pictures but I was in a hurry.
