Back to the Triple Expansion Steam Engine
I installed these cylinder drains on the triple, but was not satisfied with their appearance because they looked too big. So I bought some of a different pattern from Reeves UK.
The new cylinder drains are smaller, and have a handle which is suitable for joining all 6 drains to one control handle.
The new cylinder drains are a more realistic scale. I suppose that I should have made them myself.
From above. Getting them to line up was a fiddle.
The crankshaft protractor now has a (temporary) pointer. When the timing is finally adjusted, the protractor and pointer will be removed. I am planning to make and install a crank positioning gear and pinion and lever.
The crank positioning gear and pinion shaft on the full size, ship’s triple expansion steam engine at The Geelong Showgrounds. It is on the low pressure end of the engine. I will make something like this to act as a flywheel on my model triple.
