I think if I needed to move something, I'd sooner get a cap/plug for it than trust the JB weld.
I cant believe nobody mentioned just drill out the hole and pay a welder to install 1/2" SS coupling. All is not lost, just spend $20-40 for a quick weld job and $6 on a coupling.

I guess i missed that one. What ever happened with this situation?
