Ruined threads on brew pot

I received a 42 qt polarware brew pt from my parents as a gift while on deployment last year. My parents bought it in nov 2011 but I didn’t pull it out until now to use. When I tried to attach the spigot I saw that the threads have been pretty much sheared off to the point that I can only screw the spigot on 2 full revolutions before it refuses to turn any further. I can’t return it because it was a clearance item from the brew shop and it was bought too long ago. I figured I could just solder the spigot to make it watertight. Would I have any issue with bacterial growth inside the spigot if I was unable to remove it or could it just stay on permanently?

Can you take it to a machine shop and have the threads re-cut?

J B Weld?
Holds most of my brewery together!

Or drill it out and use a weldless fitting?

Yeah retapping would be a much better option than welding. That is so much more permanent.

I agree with re-tapping it.  I don’t have a tap large enough even if you were my neighbor, but a machine shop should be able to do it for you in just a few minutes.  That’s a much better fix than anything else you could do.
