I used to us hickory rods and turned wooden balls , but the last five years I have been making them out of brass rods cut on the end with a concave radius to match the ball, and forks of deer antlers much like the ones stumbling wolf makes. I also "spot drill" a hole in the side to fit over the ramrod so I can give the rod a "tap" if necessary. If you drop me a pm with your email I can send you some pictures.
