One of the things that would most certainly give me nightmares is Walschaerts valve gear, so I find this picture Himself sent me of one complete set ready to be installed on an NGG16 power unit quite astonishing.
I am not mechanically minded at all.
In fact I don't mind admitting that I struggle to following what all the bits pieces are doing when they're cranking around and jiggling back and forth.
All I know is that I'm in awe of both the people who design the etches and those, like Himself, who can put it together.
I can't imagine it will be very long before this is fitted on the power unit and ready to be tested.
Watch this space......
