The better quality die stocks (e.g. Campagnolo) are piloted to help start the threads in the proper orientation. The Hozan tool is not piloted and will be trickier to get right.

a very good way to thread things with many TPI is a lathe for threading pipes. The only requirement is to have the fork fitted onto a pipe centered on the steering tube, and that lathe should have a 60 degree cutting tool, and a suitable pitch.

I would not attempt this or have anyone else attempt it.
A fork designed to be threadless is very unlikely to have the wall thickness to support cutting a thread into it. The steerer may shear off either during threading or in service.
It will also be very difficult to cut such a large and deep thread by hand and obtain satisfactory results.
The die linked above is intended for chasing or maybe extending the existing threading on a fork. I doubt you could cut a full thread without dulling the die to uselessness.
