Lads on my motorcycling site posted this up. They are pretty amazed at it. Not being into modelling I don't know if this is special or de rigeur for you boys
 
 
Whaddya think?

Interesting. Nice engineering but I was puzzled by the lack of gaskets, bearing shells etc. There doesn't appear to be any ignition system either. Since it's presumably run by compressed air, the cam/valve timings must be different from an internal combustion engine.

Beautiful machining - I have to hand it to people who can make 12 of something and have them all look the same.
 
And the video is something to which we all should aspire. It is worth watching over again just to see how he did it.
 
So it runs on air? Who cares; it is a lovely job and I got pleasure from the posting so thank you John and thanks to the blokes on the motorcycling site who recommended it.
 
My bikes are only twins: Bonneville and Honda CB350. Do I need a four?
