Wow Tony ... that looks far better than most commercial jobs. Looks quite stout and with all those heat exchangers underneath, it ought to make steam enough to really give that little engine all it needs and more!

Hi Jan,

Is the heat exchangers underneath solid copper rod, like one would use on a porcupine type, or hollow tubes?

Solid 2 mm rods bent into a staple shape.  I had built several boilers using hedgehog/porcupine rods but it was sometimes a bit difficult to stop them moving during soldering, it is quite difficult to turn a should on small diameter copper rods so I came up with the idea of using a staple shape which are sort of sprung into their holes and pushed down onto a spacer which keeps them all the same height; this spacer being removed before soldering.  I don't think that small hollow tubes would have any advantage over solid rods as I think they would soon clog and if the boiler ran dry burner out.  This is only an opinion I haven't tried using tubes except in larger sizes.

Take care.

Tony

Thanks for clarifying Tony.

I assumed this was the case, and eventhough i´ve never tried it myself either, i have to agree completely with your theory, regarding tiny tubes under there.
I really like the look of the "staples" over the usual "hedgehog quills". Looks way more organized under there...which suits my OCD perfectly ;D

Beautiful work Tony!

I know it won´t be visible under normal circumstances, but just knowing that it looks like that under there, and not just some "nails" poking out through the boiler, makes the entire vessel a much nicer and more finished looking product in my opinion.
Cheers
