Repairs While I Wait for Some Rain

 We've had less than 1" of rain in the last 6 weeks. It's sprinkled a bit today and the forecast calls for a 50% chance an inch or so tomorrow. I hope we get it, as everything is already crispy and the forecast goes on to say the next 10 days will be 80º and sunny.

There's not much for me to do but get equipment ready.

My first attempt at welding cast iron. I've brazed it before with some success, this is going to be an experiment on a "low value" part. I'm using the Shark brand 11087 0.125" rod at 80 amps (220v). Any higher and I burned through. I increased it a bit on the following passes.  Looks like I should have used a carbide burr to widen the crack, not a grinding wheel. I went back and cleaned it up a bit before I added more weld.
Pics of the finished repair. Pretty happy with how it looks, there's a bit of weld undercut where I was too hot. The spatter/beads are cosmetic. The real test is to see if it holds up.
