This is my version of Stew's and Les Moore's Overcrank,minus the large flywheel and govener.I shall make an angle valve for the top of the steam chest.
I was a joy to make and something different,now its back to my skeleton clock.
Interesting engine Don. It appears as if the "connecting rods" are a pair of crossarms connecting long rods, much like the arrangement in a Coombes Mine or Table engine but in a horizontal configuration. Is that right?
