David, just out of interest,will the ethanol produce less water vapour than the purple meths that we get from the chemist/drug store? And I wonder which of these fuels burn hotter?.....OZ.
OZ.
Yes.
But.......
I find "meths", quite adequate, for
test purposes/ cleaning etc.
Running a burner under a steam engine boiler, will produce sooting, after a session.
A small flame, to test an engine for a few minutes, will not be noticeable.
I've never noticed water vapour, from a flame. My recent problems were caused by warming the sheer mass of the castings.
When it comes to showtime, and several hours running. I find the denatured alcohol is much less sooty, and hotter.
A pal, with more experience than me, advocates shellac thinners. Though, I've not managed to locate any, as yet.
I always think. Schoolboys managed very well with what was available at the time.
Mum's sewing m/c oil, and a medicine bottle of meths, filled at the chemists, (for a shilling)........
I think, it's better to develop, over time, and experience, what suits
you and
your engines.
