Hello all,
I am a long time model engineer (40+years) and have built all sorts of model steam engines and boilers (which is a speciality) over the years and for a long while I've thought it was past time I dropped one into a hull. (So many ponds around me, so few boats!) I already have a hull or two in mind, but I have a lot to learn (ie, everything) about marine modeling so I'm here to try to absorb as much as I can.
In the meantime, while I lurk, I do have quite a bit of experience in building model engines, the Stuart engines for instance, and in particular copper boilers and fittings. I must admit that most of my boiler building has been in locomotive type boilers, from 2" to 6" diameter, but I have done a few small marine boilers and the tools, materials, and techniques are the same and I would be glad to field questions and share what I know should the need arise.
