Just go spend $50 at Harbor freight and get a new one? If it were going in your home I wouldn't mess with it, if it's going in your shop or something i'd probably just mig it bak together and keep an eye on it for a little while. *edit* If I remember right they're just shitty steel, unless it's an old one then it might actually be
cast iron, and I'd go get some nickel rod just for piece ...
