sry guys, I just dialed in, and saw this... had to put in my two cents to save you some grief.

I'm using Silver Solder and if I remember right the only way to work harden copper is pound on it or bend it. The heat used to Silver Solder it will anneal the copper if I'm not wrong.

How would you do this if you had to make an intake then?
