I saved the football knockout from the SFB and cut two pieces one off each ends. Drilled in holes, put it on the grass and banged it with a hammer to get a decent curce to match the inside of the grill. Then I painted with high temp spray paint. I think it came out kinda nice. The metal was harder to cut than I thought it would. I was using a jig saw at first, then went and got the sawzall. Was easier to cut, but still tough. Good thing my 14 year old son helped me! Piece that went on the inside Piece that went on the outside Chargriller stock thermometer removed 3" Ebay thermometer that i'm installing. Too bad it's not adjustable! Finished!
