Putt-Putt

Sketch of Putt-Putt Boat

Affectionately known as a putt-putt boat as this is the sound it makes when fired up. It consists of a thin boiler about 1/16" thick, the bottom half being formed the top half being a thin shim of brass. Two small bore tubes are brazed into the bottom half and project down and out of the back of the boat below the water line. Elevation - note thin shim used for top surface of boilerThe unit is started by first filling the tank up with water through one of the tubes. A source of heat is then placed under the boiler. As the water is heated (there is only a small quantity) it turns to steam and gets forced out through the tubes forcing the boat forwards. Plan viewMore water is pulled in through the tubes and again gets heated. The result is a pop-pop sound and the boat moves forward.
