Hi without sounding critical the engine looks beautiful but somewhat noisy is that the feed water pump also would like to see covers over the slide valve rods which is a potential spot for steam loss ,open to commentCheers and merry Christmas to all

Hi John,
Yes I agree it's a beautiful engine and it must cost a fortune that would make your eyes water and a big hole in your bank book.
It beats me as to why manufacturers make piston valve engines that don't have seals top and bottom of the piston to stop leaks, if you look closely at the engine running there is already steam leaks from top and bottom, very little at the moment but will become greater the more the engine is run.
It is so simple to use an "O" ring held in a recess with a flat plate to retain it to stop leaks top and bottom.


By the way it's not a slide valve engine it's a piston valve which makes it easy to have forward and reverse by switching the steam from one port to the other just like an Oscillator using one servo.


Have a Happy Christmas to all.


George.
