Steam Machine




A Lego Technic steam machine powered by two pneumatic cylinders engine, with valve gear mechanism, speed indicator and air control valve.

You can use the color you want for the pneumatic hose. They are in color in the instructions for viewing convenience. You can also use different lengths of pneumatic hose (including a bit smaller).

You need to use a air source which is not in the instructions. You can either use some lego pump (you can watch here a 4-pump hand pump inspired by Philo's work) or use a compressor. The pneumatic switches and cylinders are not modified. More information about the functioning, design and how to test you switch of my blog here.
