Made a model of the Nut - both halves together with whatever flange
needed...

Drill - and then bore out the hole on a lathe. Then cut a thread.

Forget taps. Ste the lathe at 10 and use the correct cutter.

There are even carbide threading rods with a set of 60 or xxx degree
cutters. Buy the right one - shape of the thread and bore a thread.

I'm retired and tired.. of winter..

If not, standard threaded rod will get it back in service quickly,
with the same inconvenience as reading a lathe dial backwards when
boring, or you could redefine the directions of the axes on your
drawings; Y is normally reversed anyway. I've markered a diagonal
arrow next to the feed handles to relate the rotation to table motion.
