I made a few antler tipped strikers a few years back.  I used 1/16" brass rod stock to join the antler piece and the wood striker.  It was a lot of work and I really didn't care for the sound.  I was getting too high a pitch for my taste.  This may or may not have been due to using the brass rod.  It worked well with acrylic tips on wood strikers,  but I didn't like the antler tips.  If you try it, let us know how it works out for you.
