Hi AdeV,
It just occurred to me that you don't have to make a complete new nut, just make the lead screw slightly larger diameter, and the acme tap of course, then enlarge the thread in the nut. Should save a bit of time not having to screw cut the thing. There is no good reason why you have to stick to standard sizes if making your own tap.

Ned - I'd love to, but unfortunately 90% of the wear is in the nut, and the remaining thread is now very thin... TBH, it's going to be a lot easier to make the nut than it is the leadscrew. I'm not sure how easy it's going to be to cut silver steel, with only hardened silver steel...

I've cut the end off it twice, but it's still too short

I'd Grind up your cutting tool from an HSS toolbit, I think you will find it hard going trying to cut SS with SS and you don't want to have to regrind partway through if the edge goes off.
