Thank you for your praises!
Kim, I don't want to keep it that shiny, acutally I want it to get some patina, only exhibits stay like that
Zephyrin, there are at least two models of that boiler that were built before I did it. But they are somehwere from Germany or/and the Netherlands. I have never seen in real though.
And there has at least been another one, which is shown in "Handbuch Modell-Dampfmaschinen", that is kind of the "steam bible" in german Language.
I don't know much about where they were used but wikipedia says it was mainly used in marine applications, either fired by solid or fluid fuel or used for heat recovery from large combustion engines.
The movie of it under steam will come, I promise!
Now where have i been.. Right, fitting and pipe work:
I had to make those sealing "spacers" (used together with the O-ring) for most of the fittings. I also needed to solder a few pies into flanges and reproduced the pressure gauge syphon (the old one was bent too often and not looking good anymore).
To seal the connection between copper tube and pressure gauge, I tried making a 2mm compression ring and well - I was successful! Oh and I never want to do it any other way, because this is so easy in use. No soldering and cleaning off flux, no fiddling around with teflon tape.
You only put your nut on the tube, followed by the compression ring and then screw everything together and tighten it. And there you have your connection.
But i was not just doing well this evening. I managed to break one of the wooden wheels when trying to mount it. Why this happened? Well I had been treating the wooden parts with bees wax before (i acutally threw those parts into the molten wax) and well the wood changed its shape. It acutally shrinked a bit and when I started tightening the screws, the wooden ring was split immediately.
Well - i'll need to make a new one then!
To be continued in a few monents..!
