Overview: In this episode, which comes from the Greater Manchester Museum of Science and Industry, each team is required to construct a steam engine capable of lifting a weight into the air. Heinz Wolff and his guest Fred Dibnah, an engineer and steeplejack, discuss and judge. Meanwhile, Lesley Judd catches up with the progress of the Incredible Egg Machine. Fred Dibnah was elevated to fame through a television documentary made by BBC producer Don Haworth in 1979. Haworth became interested in Dibnah after his appearance on BBC North West regional news, which reported on his daredevil work as a steeplejack. Dibnah went on to feature in many TV programmes over the years, sharing his engineering and industrial knowledge, especially in the field of steam engines, which proved highly popular.
