External threads on a dowel. Possible?

Question

I saw a reference about cutting a hex nut in half to use it to put threads on a wooden dowel. Short of buying a manual wood threader, is it possible to make a shop made wood threading device?

Answer 1

Instead of a nut, I suggest using an ordinary threading die. Nuts do not have the cutting edges, taper, or relief needed to make good threads. If you get a die, get the coarsest thread you can. Since you are cutting cross grain, you can expect pretty crumby threads. The big advantage of a die made for wood is the much larger threads and a cutting edge designed for wood.

Answer 2

A metal turning lathe and a tool with an Acme thread profile can make that thread easily and quickly.
