Imgur user [Jefenry] designed his Dahlgren cannon using 4130 seamless alloy stainless steel with a 1-inch bore. The barrel fits snugly into his steel carriage with brass wheels, which was laser cut for an exact fit. Elevation is adjusted using a simple screw and sighting in is accomplished with a detachable scope... (continued)
