Re: it's all wobbely! my pipe that is, help for fix?
I've held my tongue long enough....sorry if I offend.
JB Weld is a cheap, cheesy fix if it is a fix at all. It will not work for this application, as Bikeguy said, and unless it is just used as a filler, it is, at best, a temporary band aid.
Brazing will work, but use MAPP gas, not propane. However, if it is a chrome part, enough heat to braze will discolor the chrome quite a bit.
