The antler tip is attached to the horn using a piece of brass tubing. I don't have any means to thread the main or tip, so I just used the brass tubing as a coupler. The two pieces are glued to gether using epoxy. Not PC or HC, but it worked. I am low budget type, I use what I have on hand at the time to get the job done.
Good luck on your efforts.....Tim
