How I Built a 3" mortar Cannon out of and old fire extinguisher.
DO NOT TRY THIS AT HOME.
I have been Engineering for 30+ years and Building Guns for 20+ years. The Inner core is very important, DO NOT attempt this unless you are competent and have a thorough understanding of explosive pressures and metal schedules etc. Building guns of any sort is very dangerousand not for the inexperienced. You have been warned!
