Awl--
I'm putting a 3/4 sweat fitting OVER 1/2" brass pipe, cuz, well, I think I have no choice, cuz the brass pipe will be cut, w/ no thread. The fit is loose, about .020 on radius. Do you think sweating this is still OK? Solder won't be too weak?? Other choices? Saw the JustforCopper link--might could do that on nice slip-fits, but doesn't sound suitable for loose joints.
Also, I have heavy rosin core solder, almost as heavy as plumbing solder. Is it usable for normal sweating, and for this abnormal sweating??
I guess if I had to I could braze it... been a while since I've brazed, and wasn't too swift at it when I was doin it!!
Interestingly, HVAC copper A/C piping/joints are brazed, *without* flux!! They use a funny kind of rod, sort of rectangular, IIRC. Anyone know about this??
Thanks.
