Excellent build log David, have just read all the way through with great interest and learned a lot from the work holding set-ups and the design, especially of the epicyclic geared cam drive and internal fan to stir the air in the crankcase.
Many of the work holding set-up were especially interesting, this being an area where I have little experience – that proved invaluable.
The standard of machining is excellent too, resulting in a lovely engine to be very justifiably proud of.
Well done that man,
Chris
