Turn the taper then cut the thread.
Of course if you ain't got a lathe, you is knackered.
Then again you could pay Flak to do it. Sorted.

You'll need to mount it between centres with the tailstock offset. Drive the other end off a dog and cut the taper and follow it with a thread
tool.

If it was really important I could do that for you. I have a CNC lathe. That said...what an effort. Taper threads are usually very short - why so
long?
