"Beamer represents a large victorian style beam engine that could have existed in the mid to late 1800's. It is a unique design and nothing like it has ever been done before. A belt driven cooling fan allows the engine to operate continously at a temperature only slightly above ambient! All shafts are fitted with ball bearings for a smooth running and maintenance free engine. An operating flyball governor which is driven by the fan belt adds much interest to the engine, but it doesn't regulate the engine speed. The engine runs at a nice leisurely pace from a 1/4" dia. x 5/16" tall flame of an alcohol lamp, or one of my mini propane burners as shown." - Jerry
