Thank you all for the suggestions.
I found a solution by using the Beall Wood Threader.
I made the threads on the male side easily and they look great.
The taping of the threaded hole on the female side was another story. I was tapping g into end grain which, by Beall's own admission does not work very well. What I found however was that while the tapping did not produce crisp threads, it did produce usable threads. Seeing that they will be invisible in most cases I decided to use them. I also poured wood stabilizer into the hole and allowed it to coat the threads.
