Dinkus - A Side-Crank Rotary Valve Engine

[dudeface]

If the cranks for the side rods are set 180 degrees from each other, that won't work. They have to be 90 (the way locomotive side rods are set).
(Bentley once made OHC engines using the same system to drive the camshaft, so it certainly works.)

Never mind, still good going - I think your record of successes vs failures stands up for itself! 

Onwards and upwards .........what's next? 

To quote Mr Lennon, a new one just begun!

Cheers. They are at 90 deg, I think I've made too many small errors and my implementation just isn't great.
