"Brazing cast iron is the only way to repair. JB weld will hold a loose piece in place, but will let go if you ever set the fan down on that area. I have brazed engine blocks cracked from freezing and are subject to vibrations unequal to anything a fan can generate, and it holds great. If you sell the fan down the road, there would never be a worry for breakage. If a replacement does turn up, have the old one brazed anyway for a spare. Its far from trash."


There's a reason for this: BRAZING IS STRONGER THAN CAST IRON, at least the old impure stuff that our fans a made of.
