Another step towards steaming up the boat. I have now all the connections made, both gas and steam.
There was a small ordeal with one of the connections I made earlier, though. The pipe that leads from the boiler to the gas regulator valve somehow wouldn't hold. Turns out I used a wrong locknut. Since I got the valve from a different vendor than the boiler, they're using a differently threaded system that isn't quite compatible. So I had to unsolder the fitting and replace the nut. But after that I realized that the fitting and the nut aren't compatible. So I had to unsolder yet again and replace the fitting with a small adaptor tube and the correct fitting
After I had sorted it all out, everything turned out to fit nicely, at last.
Next step will be leak testing all the gas pipes and connections to make sure everything is, well, leak-proof (gonna use some soap and water). We don't want any gas leaks inside the vessel
If everything goes well, I expect the first trial steam up this weekend. Keep your fingers crossed.
