Hey Ernie & Skelty, thanks for the kind words :greetings-waveyellow:
Yeah as SBB said, the top has to be open otherwise you are creating a steam bomb that can KILL, MAIM or burn your shed down very easily, it's great that you taken up an interest in this but make sure read and understand everything before undertaking building anything.
There's some great resources in the forum library

Yep they are soldered with silver solder (make sure its silver solder and not lead based), the stainless ferrule was brazed to the copper.
If you've got any questions feel free to ask mate, we all start somewhere :handgestures-thumbupleft:
