Whilst working on other projects, I have been tinkering with this for a while.
Running nicely on less than 10psi now.
I have a hull for it, just need to find time alongside other projects now!

Now thats a nice bit of tinkering :-))

Nice, what make is that oscillator?

Thanks for the comments, its a Stuart Turner.

Hi Ian....I am sure we steamers always love bright & shiny brass, copper & black steam bits :-)) ....however one question
In IMG.1254 we see that the gas regulator [Forrest Classic?] pilot pressure is taken as steam from the top of the boiler & not from lower down in the boiler casing as lower temperature water
1) if the Forrest Classic regulator has a neoprene diaphragm is that OK for say 150 degrees C? or do we consider that the steam will condense & hence loose temperature.....
2) would there be any issue with the pilot signal being a gas & subjecting the diaphragm to any throttling effect?..................................................... <*< Derek

The installation instructions show the boiler side connection on the top of the boiler, so, on first run, steam will condense in the sensing tube and stay there until/unless the unit is disconnected.

In my steam plant I have connected the same gas regulator from Forrest Classics to the lower parts of the boiler (water portion / bottom of sight glass fitting) and it works very well. Also allows for shorter pipes which keep the plant looking neat.
-
Are you saying you have connected to the sight glass drain? If so, you are bypassing a safety element that allows you to blow out the sight glass and prove it is working ok.

There was no drain valve to the sight glass, so I'm not bypassing anything. Many if not most of the model steam boilers available have no drain valve at the sight glass.
Besides, I have discovered a very practical method of removing air bubbles get trapped in the sight glass ok2

kno3 .....says "I have discovered a very practical method of removing air bubbles get trapped in the sight glass" ...so kno3 O0...please tell us
My ACS VB2 boiler does not have a gauge glass blow down valve, but it does have a lower boiler tapping [1/4" x 32] which I will use for the regulator pilot pressure source..............Derek

Great workmanship Boatmadman! O0 :-))
Just lovely . . .
Erm . . . .
Is it me though . . . . .
or does this look like something from a Wallace & Gromits basement?? %% O0 {-)
-
I like pipes and tubes wandering about! :-))
-
Yeah! :-)) fantastic.
Don't worry about me! O0
I'm only jealous of folks that have the tooling to turn out such gems! <*< >>:-(

you hear a lot of people say if only I had a lath I would make one of them , It's not the tooling I have the tooling but not the skills and know how, that engine is a very nice job

Derek, here's the answer. I have posted it in a separate thread so it's easier to find:

I should point out here that whilst I machined the engine, it took someone far cleverer than me to make it work!
I was given the boiler, the oil/water trap was made for me but I did make the lubricator.
I did manage to put it all together all by myself though :-))

Hi,,,oh yes... the plant look real fine,,,and it is a good ide i will try it
