The great horizontal steam engine is Fascinating! And thank you for introducing us to the model. The routing of the crosshead is interesting and resembles the crosshead routing of steam locomotives. Michael
Slide valve eccentrics are set to 90 degree + lap angle + lead angle in advance of the direction of travel. With the engine on dead center (top and bottom) lead should be equal on a horizontal engine, on a vertical engine additional lead may be required on bottom dead center. Lead is the amount of opening of the port. Hard enough to measure on a full size engine, probably harder on a model. This is what I was taught 40 years ago learning to be a steam engine driver.

Thank you again love these engines
Glad you like them!
Fascinating! 👌👌👌👌
视频很棒，点赞支持，多多更新哦～👍
Thanks for the hint, I somehow missed out on that rebuild. Lovely engine!
I made the original video a few years ago, there are now over 2,500 videos currently on my UA-cam Channel.
@@keithappleton And very good they are too.
I made a steam engine some time ago just using a drill press Vice and a mini lathe runs good
⭐🙂👍
should every steam engine have personal history included with it ?
I don't think so - Why ...... ?
@@keithappleton just to know the history of it?
