Darren:
Thanks David, I was wondering what the bars where for.... :ddb:
John Hill:
Nice work David
It is a pity about the condensate and I realise it would not be a good idea to build an injector to put that oil contaminated water back in the boiler, so scrub that idea.
But how about reheating the steam/water before sending it out the funnel? I am thinking there may be room to route the exhaust pipes through the 'firebox'?
NickG:
Yes, it would be a tricky to make it run in reverse. Flicking it backwards won't work, you would need some sort of valve that would swap the inlet and exhaust port on all 3 cylinders! On the Mamod traction engines they have a lever and 3 ports instead of two. The lever sort of shifts the whole cylinder up to become aligned with either the middle and bottom or middle and top ports for each direction. So the middle port is a sort of common exhaust port! Not sure exactly how it moves the cylinder whilst keeping the pivot bearing still, it must be some sort of primitive cam arrangement I think.
To make it double acting would require a full redesign as John said! In fact, you might as well start from scratch as the port faces don't go down to the bottom of the cylinder etc. :doh: You might be able to keep the flywheel, cranks and main bearings, but unless you were going to have a very short stroke, bin the rest and start again!
