Thanks everyone, the repair worked. I probaby would have welded it without taking the end off. It gave a chance to clean the dirt dobber nests out of it better too.
I have one other thing I would like to do is rewire it from 110V to 220V. The way it is now A+B are wired to Neutral and C&D are wired to 110V. Would I seperate C&D and wire each to a 110V leg?.
