Dean Alling's 1920 20 hp Minneapolis, made by the Minneapolis Threshing Machine Co. When Dean (shown here at the wheel) was searching for a steam engine to buy, he wanted on ebuilt between 1914 and 1924 because of the boilers typical to that era. "This one has a butt strap boiler (which is a stronger boiler) and it also has an ASME code boiler. In California, you're limited to 100 pounds of pressure, unless it's a butt strap boiler."
The Minneapolis, belted up to power the sawmill at the Antique Gas and Steam Engine Museum at Vista, Calif.
Dean Alling's next project is a companion piece for the Minneapolis: he recently acquired an original Minneapolis water wagon. "It's rusty, but it's complete," he says. "It won't be as big a project as the steamer was."
