Anneal the stuff as discussed here some time back. Heat the bit of
tube where you want to bend it, and a bit on each side, to redness,
then dunk it in cold water or play water on it to cool. It will
then be soft enough to bend easily.

That's interesting. Never tried this before. What do you mean by redness?
Copper tube is naturally an orange colour, so it's not particularly
obvious
(to me).

You heat the pipe with a powerfukl blowtorch (best use two) until "cherry
red" and then quench it in water. It has to be cooled immediately.
