I bought some blacksmithing tools that had been sitting in an old barn, buried and rusted out. One item was a champion blower. It was completely froze up. Lots of lube later, I got it running again and it works beautifully. Blades are very free and it turns easily. Painted it and prettied it up for my forge. Only problem is first day using this, the housing broke. You can see the crack running down the side. Anyone have any advice on fixing this. I've got a little flux wire welder and can certainly run a bead down it, but I'm thinking it is cast iron and the weld may not take well. Any ideas for what I could do here? I've put a lot of effort into this and don't want to give up on it.
