Bert: I have made molds for all the rifle and pistols I have built. You have lathe I presume. That radius cutter would speed things up, but just simple tools will do the work. Molds are two duplicate pieces, I have made then from cast brass, and also forged them from wrought iron. There is info in books that might help you. I used an old cherry years ago to make my first one. After you have the round ball,setting out there on a a stem, thats then the filing begins. A triangle file with one side ground smooth, is the filing tool. I love this web site, but you get to many negative post on somethings that you might want to do. Do it --- Mail me if you are interested and i'll tell you how to make a round cherry using a lathe, there are two ways. PS I've also made the ball end in a electric hand drill clamped in a padded vice. Don't ever be denied. Regards Dick
