I wanted to build a Steampunk Gatling Gun. I spent a little time doing some research and did some drawings and this is what I came up with. The whole gun has been built with recycled wood. The base was made from an old wooden bed and the rest was built with scrap wood that I had in my workshop. The gun does not fire real bullets but the barrels do spin. I used an old angle grinder head as the crank handle. The gun is just over 3.5ft long. The only item I spent money on was the copper tubing.
