  I'm thinking at this point that I might try threading the inside with
a boring bar and a cutter that is close but narrower than the groove
width of the thread . This will make it necessary to split the nut and
hot form the thread . My main concern about splitting the nut is whether
the halves will fuse together into a solid unit during the forming
process . I'm once more stepping off into unknown territory ... but you
know what they say "keeping learning will keep you young" .

I might thread a test piece first, in two halves to check the fit and measure how far is left to go by the gap. One side could be clamped to a faceplate and the second side doweled and bolted to the first, to allow opening and reassembling the test piece without losing registration.
When I rethreaded the soda bottle neck I first zeroed the lathe bit depth on a male garden hose fitting.
