An interesting idea – using a bioler instead of the more usual type. But as usual, we might guess that you need a boiler to raise steam for a model – is that correct? Then there will be questions like 'how big' and 'what pressure', as well as 'have you done anything like this before – ie made something that could blow up in your face and take the shed roof with it?'

Slow down Kevin, "bioler". Let's try "boiler".

No problem, carry on Kevin! ( if you read Tim's post, I think he was initially pulling your leg a bit)

Longtimes ago ME published a Tubal Cain design and construction series for a 3" vertical boiler. Very simple and satisfying to make with a central flue and 3 water tubes crossing the firebox. My gas-fired example steams at up to 80 psi and runs my Stuart Turner engine nicely. 'Fraid I can't recall the ME issues.

Tubal Cain's 3" test boiler was described in ME 18 Feb "77. I made one and you can see a picture of it, and the GA drawing of it in my album. It steams my ST10 quite well on only 10 PSI or so.
