Hi Ross,
Long time no hear! Have a look at these -

Setting up Mach3 for lathes:

And my favourite manual thread cut video:

My understanding is you don't necessarily need a special VFD / motor combo for CNC thread cutting, just a good pulse feedback to Mach3 (through an interface card I believe) so that the feeds are synchronised to start at the same point on each pass.
