The Steam Hammer Is Alive, but at What Cost?
About this video
Steele upgrades his workshop to support running his newly restored 1915 steam hammer on compressed air. He installs a new 40 kW compressor and replumbs the entire workshop with industrial aluminum piping supplied by Preuost, replacing the old nylon plastic system that had become unreliable. After connecting the steam hammer to the compressed air system and having electricians wire in a dedicated power supply, he fires up the hammer for the first time, discovering it requires significant electricity (£4.74 per 6 hours of runtime) but produces impressive forging results—though the compressor struggles to sustain full power for extended heats.
Key takeaways
- Quality components and tools matter: Steele found aluminum push-fit Preuost piping dramatically easier to install than steel threaded fittings, completing in 2.5 days work that would have taken days alone
- Proper infrastructure planning prevents costly mistakes: He had to troubleshoot leaks in black iron connections while the new Preuost system proved leak-free, showing the value of planning with appropriate materials upfront
- Efficiency varies significantly between machine designs: The steam hammer requires a 40 kW compressor despite similar falling weight to his 7.5 kW Stanko, demonstrating how mechanical design (self-contained crankshaft vs. external compression) affects power demands
- Testing reveals real-world operating limitations: The 40 kW compressor sustains the hammer for only 30 seconds to a minute per heat, showing that specifications on paper differ from practical workshop conditions
