Hi Craig, wonderful to see it running so well. A very unusual engine indeed masterfully executed. It has been a instructive journey to follow each step along the way, and I always look forward to another day’s progress. And real craftsmanship at every step. Congratulations on completing such an usual engine.
I guess the somewhat complex mechanism is to get a long stroke on an atmospheric engine without an absolutely huge crank throw. Or are there other reasons?
Do you have much feeling for the power when it is loaded enough to fire every stroke?
Thank you for posting the drawings. I am a long way from being able to build my own, it would be my first IC engine, and I suspect too much of a challenge for that.
But if you don’t mind I am going to download them anyway and spend a good few informative hours pouring over them. And who knows? One day ......
