Tank leaking at hinge

A fellow brazed and tested mine for forty quid, six years ago. Its been no trouble, stronger than before probably.
POO15 guaranteed for two years... Good luck with that!
I have another tank from Jez900ie, which is Silver soldered and is equally successful. Jez reports using it for some time and no leaks... Yes common problem with the hinge cracking I'm afraid. Caused by lifting the tank with too much fuel in it. The weight twists the bracket and snaps the spot weld.

Brazing and Silver soldering both use a flux, which causes the molten metal to seek into tiny cracks and gaps. POO15 can only ever sit on the outside masking the leak, it cannot add any strength... Leave it in the shop.
