Good job, Little Norm!. That was the best explanation / demonstration of the Stephenson gear that I have ever heard.

Very clear explanation of the difference in valve gear between the different engines. Probably one of the best in my opinion since you showed all the parts and motions along the way. 👍

Thank You for devoting your life to old iron culture; if it comes that far, the future metal men will honor you.

G'day Norm, That is really facinating not only to see how steam valves work, but also to see the machines that are used to make the required parts. As a retired auto transmission mechanic I like seeing how things work and you do a very good job of doing that. Trev from NSW Audtralia.😊

Thanks for including the diagram of the Stevenson's. Was the last nudge my brain needed to get the concept that one of the rods is just waggling the mechanism while the other rod is moving the valve 🤜🧠
