Thanks guys. there is solder and there is solder. I remmember back when I used to make leadlight windows I used a very hard solder. I think I'll try that stuff, other than the soft electrical wire stuff, and see how that goes.

We use (US made) pb for drinkable water here and our water mains around the town are in "big bore" pb or some form of plastic.

We don't tend to DIY air con in this country, although that looked fun too.
