The thread is actually a square profile the tool was slightly narower than the finished thread once it was cut to depth i slowly widend it untill a good fit was achived.
I was talking to rob wilson he sugested making a silver steel tap at the same settings as the screw this would be used to finish the internal thread :bow: :bow: :bow: :bow:

Thanks, John.
It did occur to me that, if making a silver steel screw and bronze nut to match, maybe one could get the nut nearly there on the lathe, and gash flutes into the first turn or two of the finished screw to use it as a tap to finish off. But hardening/tempering might distort the screw, and I don't know how well silver steel would cut bronze if left in the raw.

Really? I'd be quite surprised if heat-treating silver steel/drill rod would deform it. (If done properly, that is.) It's basically designed to be heat-treated, n'est-ce pas?
Didn't you say you were making the leadscrew out of SS? If you made it a bit longer, you could part off the end and make it into a tap exactly matching the leadscrew's threading. :D
Or am I all wet?

Nope, your quite dry on that one. Tap would be made the same way. Nice short cut you thought of Tinkering_Guy.
