The James Engine is a new design the allows multi-cylinder two strokes to be manufactured with fewer parts and greatly reduced machining requirements.  

This design can also be applied to steam or air pressure engines where a cylinder head is not required for operation.  The air pressure is applied to the underside of the piston, allowing the top end to remain open.  In this configuration, the pistons can be viewed while the engine is operating. 

The HEX-2 and HEX-4 were built to demonstrate and verify that the design indeed works.  I asked Ron Chernich to review the plans and here is what he had to say about them:

“…you have managed to design the simplest, practical twin I’ve ever seen, and your presentation of plans and instructions are top-rate; so sincere congratulations.”

Updates:

- ”HEX-4” Castings are here.  I say “HEX-4” only because without the hex shaped 

  crankcase the name no longer makes sense.

- Patent # 7,331,324 issued 19 Feb 08.

- The plans for the HEX-4 will be published in the next Model Engine Builder 

   Magazine—Issue #14.

- The HEX-2 plans were published in Model Engine Builder Issue #9.
