Gunderson Do-All Machine

Gunderson Do-All Machine

The Gunderson Do-All Machine is a colorful, interconnected network of dozens of machines that have been cross-sectioned to reveal their internal operating mechanisms. This artistic feat of engineering was designed by Mark Gunderson to serve as a mechanical tutorial for young and old alike.

History and design

The Gunderson Do-All Machine includes more than 30 individual machines that are linked together by an array of belts, gears, pulleys, and transmissions. Collectively, they operate in a continuous chain reaction on the power of one 10 horsepower Whitte gas oil well engine. During full operation, the Do-All becomes a mesmerizing kinetic sculpture. The entire network is mounted on a 15-foot flat bed trailer platform, so that it can be transported to engine shows, educational venues, and county fairs. The combined weight of the trailer and all components is ~6000 pounds.

Created to serve as a fun and educational tool, the Do-All's layout and design allows one to follow the chain reaction from machine to machine while observing the internal cogs, gears and other components that make them work. The variety of machines include an automatically reversing worm gear, a water pump impellar, a governor/gas valve from a 20 horsepower (HP) JC engine, a blacksmith blower/bubble maker, the main line shaft and pulley from an antique corn grinder, a floating gear, a DC 110 volt generator and lights, a 38 to 1 gear reducer, a bicycle light generator, and a fan blower painted to look like a clown. Recent additions include a penny press that creates a commemorative Do-All Machine coin and a rotating satellite dish with cheerful sun and moon images painted on opposite sides.
