Mr. Crosby, I know many of your horns involve threaded components. Have you experimented with trying coarse versus fine threads in the same diameter to see which produced the best quality of threads in the soft materials of horn and wood? For example, 5/8-11 versus 5/8-18.
I would generally think of coarse threads with horn and antler and such, but it occurred to me that as a fine thread removes less material, it might actually produce a better quality cut.
