My other vice besides building stovebolt engines is gunsmithing, reloading, and bullet casting. I got John M. hooked on reloading a while back by setting him up with a few extra loading presses, bullet molds, and other casting and loading supplies that were taking up space in my gun shop. I make cast bullet lubricant from beeswax toilet bowl seal rings, automotive chassis grease, and paraffin sealing wax from the canning department at Walmart. It's good for bullet speeds up to about 2K feet per second.
