Back to the Triple Expansion Steam Engine
by John
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.

Can you give us a rundown on setting the timing?

Someone, I will write it up when the timing is completed. I need to do another teardown to get to the intermediate valve. Reassembly then typically takes me about 6-8 hours. I keep on putting it off for some reason….. John

Hi John,
the big gear is a worm wheel, on the shaft next to him will become a worm. With a big wrench on the top of that shaft they could turn the engine to a particular position, mostly to do maintenance work..
When the the shaft is lifted the worm can take away before running the engine.
