Model Triple Expansion Steam Engine. First taste of steam tomorrow!
I was very excited to see my triple running reasonably well on air recently. But it was tight, and required a decent gutful of air pressure to turn it over. But it did go!
Then it seized.
The cause was the intermediate cylinder valve rod seizing in its guide. Probably a bit tight,and not getting any oil.
So I have loosened the gland, installed a displacement oiler, and made and installed a flywheel. I also finished the pipework around the condenser.
So, tomorrow I will hook my triple up to Stuart Tankard’s vertical boiler, and see what happens. I am sure that steam leaks will be revealed. Hopefully there will be a video worth posting!
