Hmmm, one other way to do this, if you don't have a lot of holes to do, is a single-row thread mill. traditional thread mills are good for only one thread pitch. Single row thread mills only have one row of cutting edges, so you run a pass much like a single point threading operation, but with the cutter spinning in the spindle. It does an amazing job of cutting oddball threads, and they look just like they were tapped. This, of course, is good for a mill, not usable on a lathe, as you need to orbit the X and Y axes as the Z withdraws up the hole. (You thread from bottom to top so the hole is climb milled for best surface finish.)
I have a generic c program to write the G-code, if anybody needs it.
