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.
