I'm new to BP guns, and already I can see the addiction taking root. Here's what I made yesterday afternoon, nothing special, just a ball starter. I guess I could have bought one, but this was fun to make! The antler came from a skull my son found, the brass tip is a piece of plumbing I re-shaped and epoxied to the dowel. I made the indentions with a 1/2" half-round(?)router bit, chucked in the drill press. I gave it a few coats of spar urethane and called it good.
