I'm trying to curl up some small copper pipe (or tube, if you prefer)

I tried some 10 mm (or so) pipe that I found in the cellar, and it

kinked too easily. I got some "5 mm X 0.45 mm" tubes from a hobby

shop (aimed at model railways, I think), and that's even harder to

bend & easier to kink.



Is it worth trying to anneal a piece with a blowtorch? If so, what's

the best procedure?

I just bropught some of this for a studetn project.
