Is there anyone here who has, or know of someone who has built a cannon? I am not talking about the clever people who take a piece of iron pipe and just plugging it at one end. :shake: I am talking about turning a billet of steel on a lathe with proper bore wall dimensions. I am looking into building a proper scale model Napoleon III cannon of a maximum 1" bore which is the maximum caliber allowed by the South African Firearms Control Act for a hobby cannoneer. Barrel length will be no more than 500mm What type of steel is strong enough (yet turnable on a lathe) for maximum powder charges 300grains of FFg? And where will I be able to find reputable cannon building plans and dimensions on the internet?
