Stuart Models Beam Engine - Full Build and Run.

[@gaden0114]

A nice machine, but I'm surprised that no gaskets are used between the parts that contain steam pressure (or compressed air). The piston ring, which is made like an O-ring, is also a weak point. The rubber ring will wear out quickly. Finally, ball bearings would have made the whole thing more efficient and durable. But still a nice machine that could be fun to build :) Greetings from Denmark

Thanks! Gaskets were fitted on final assembly after the machine had been painted. I agree that ball bearings would have made it smoother and long lasting, but steam engines traditionally use plain bearings. The model is never run under load and is only run every few months or so, so it’s never likely to wear out! Glad you like the engine, it was certainly fun to build and is admired when it’s run.

Very plesant to watch ! Thanks for sharing. I just wish that you show how you proceed for the timing of the sliding sleeve.

Thanks for your comment. You can find the details on how I set up the valve gear in Pt8. kzbin.info/www/bejne/r2bGmWuDbbt1ZrM

The piston does not appear to be seated correctly. There is movement where there should be no movement

[@modellingmark]

That’s very observant! It was rocking a smidge. I’ve since stripped and painted the engine and it’s seated properly now. Thanks for the comment.
