The Connecticut Antique Machinery Association's 8th Annual Spring Power-Up is planned for May 5. Featuring antique steam engines - both stationary and powering small locomotives - as well as gasoline and diesel combustion engines and plenty of antique tractors, the Power-Up is a visual and aural feast for fans of vintage machinery and engineering at CAMA's Kent, Connecticut, location.

An all-volunteer organization, CAMA is dedicated to the "preservation, restoration and demonstration of antique machinery from our rich industrial and agricultural past." Their collection features industrial steam engines - including one with a 12-foot flywheel, a narrow gauge railway and a five-cylinder Wolverine diesel that was manufactured in 1935 in Bridgeport, Connecticut. Just 150hp doesn't sound like a lot, but the engine is 10 feet tall and hits that 150hp mark at just 300 RPM.

Among other items that are often started for the power-ups are a variety of "hit and miss" single-cylinder internal combustion engines that do not fire on every revolution but only when the engine drops below a certain RPM. CAMA also maintains a collection of antique road-building and earth-moving equipment.
