Bob,
The technique described is ok, but you will have better luck simply allowing the copper to cool in air rather than quenching it. That gives a better annealing and does work fine. I remove the scale created with a Scotchbrite pad.

Hi Bill,
Tht makes sense now that I think about it. Quenching is used to harden
a material in general. If it still leaks, I'll air cool it.
