Description: Inspired by a metal diving helmet I found in the garage that my great great grandfather built I built a diving helmet out of wood. My helmet includes liquid ballast system allowing the user to change the buoyancy of the helmet like a submarine. The helmet is fed compressed air from the surface using a hose and has valves for feeding a secondary helmet as well as feeding the liquid ballast system. I have never taken the helmet deeper than 12 ft for fear of health risks associated with breathing unregulated compressed air.
