Updated version of a 3D printed working model of a Beam Engine based on the original part finished design used by Gerry.
All parts have now been redesigned to ensure correct fit. A video of the model running plus expanded views showing assembly stages can be found on YouTube https://youtu.be/dzc9QivldVk

The model runs on low pressure compressed air. Use of Silicon lubricant throughout

The use of 'Linkage' programme was essential to enable correct design of linkages required for the engine to run the Watts linkage to enable clean vertical movement of the piston rod was paramount.
