My wooden steam engine model, running off a vacuum cleaner. More about how to build the engine at: woodgears.ca . I also have plans for this engine for sale.

My second LEGO “steam” engine run on vacuum. It’s a model of an early 19th century beam engine after James Watts design, the vacuum cleaner is running at lowest power and has no problem coping with powering the engine. I hope to get a small eletric compressor to power it instead. And before anyone asks; I built this using my head, there are no blueprints or CADs!

This “steam” engine runs (backwards) on vacuum cleaner power. The motor generates approximately 700RPM. The design is based on Daniel B. Hartman’s Lego steam engines.

This is my second implementation of a “steam” engine in Lego that is powered by my trusty vacuum cleaner. The engine’s top speed is just over 900 RPM. More information, and building instructions can be found here: anthony.liekens.net

Another vacuum powered lego steam engine. This time I made the valve and power stroke shorter and used some WD40 as lubricant. Turned out not too bad but should have made the conencting rods shorter to prevent the buckling which occurs at high speed.
