Update, well I now have the engine together, as you can see I have added drip feed lubrication to the cross head and valve buckle. The knurled knob from then crankcase is the drain valve. And of course a very large exhaust.
OK George I agree but we have been calling it semi flash steam since my grandfathers day. (and he taught Alan Rayman)... who am I to argue with family
Yes I will have around 3 ft of super heater coil, on Saskia (photo earlier) I used a spearhead superheater of around 2 ft which worked well.You also said that you melted the aluminium lock nut on the piston.....
ooooo thank you for that, today I replaced mine with a cast iron one, thanks for the heads up. Boiler next step
