I finally melted my sight glass with the flames from my burner, so I figured it was time for a heat shield solution. I didn't really want to make heat shields for the valve, sight glass, and thermometer, so I ended up making a heat shield for the burner out of some light gauge steel. I started with a piece of 18in x 6in, and scored the metal so I could bend it easily. The bends in it fit perfectly around the front edge of the burner. The heat shield doesn't cover the banjo burner at all, but it creates a good enough lip to cover the edge of the pot and the stuff installed on it.
On to the pics!
