My goal is a 2 tier system welded out of angle. I am still gathering parts and pieces as well as materials for the build. In the interim I thought I could use what I already owned.
Below shows my idea
1. Shared burner between hot liquor and boil kettle.
2. March pump mounted below the bottom shelf supplies sparge water to Mash tun on top layer.
3. Room above kettles to stir.
Let me know if you think it'll work, what you'd change, or if you think it'll all get soft and bend into a pretzel.
