Very nice.  Having built and fired cannon ranging from 2mm to 12 gauge, and firing everything from ice to lead or steel balls, including miniature artillery shells, I’d hazard to risk saying this wonderful piece must NEVER be used to fire anything heavier than a wood or cork plug.   The tenons are too small to withstand fir8ng a lead ball with a realistic charge.  Somebody would get hurt when they break and potentially rupture the tube.

All that said, you don’t call yourself a machinist until you’ve spun up a cannon.
