I had a 2.25 inch x 8 TPI tap for my SouthBend metal lathe. I tapped a few pieces wooden planks to use as face plates to try to use the lathe for wood as well.. The tap's cutting edges just weren't right for cuttng threads across the grain, Oh they worked fair, using a metal lathe for wood turning is a bad idea all round.I wonder if it would work to use a metal cutting set on wood.
The male end could be done on a metal lathe. The tap, you may have to get a machinist to fabricate. Depending on the project that might also be possible on a lathe if the part would fit the chuck
