Ok, so I am in the process of building a new burner stand for brewing and I had a question. I plan on using 1/8" x 1" angle iron and the burner I already have. When I look at the design I have a question. Should the square support be bigger than the diameter of the pot or smaller? I am thinking not quite inscribing the square inside the pot diameter, almost have them the same size. I was thinking I should leave the pot hang over the edge a little to help with heat shielding. Here is a pic of what I was thinking, the square bit is the angle iron and the round bit is the pot.
