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. It was designed by Mark Gunderson to illustrate mechanical concepts.

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 Whitte gas oil well engine, forming a

. The entire network is mounted on a 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 about 6000 pounds. The Do-All's layout and design allows one to follow the chain reaction from
