Newbie here, but if it makes you feel any better, I’m in the same boat. This was a spur of the moment project idea for me. Got the inside cleaned out with some oven cleaner and noticed holes where the flavorizer bars sit. About 4-5 holes in total, most of them tiny with the biggest one about the size of a pencil.Besides aesthetics and durability concerns, are there any major operational or safety concerns with having these holes here? It seems the sandblasting removed any weak brittle metal that was remaining so what’s left feels pretty structurally sound. There is a large hole at the front wall of the cookbox at approximately the same height as the burner hole (I think for match lighting?) so I can’t imagine it’s a fire hazard or airflow issue with normal operating use?
I’m just gonna roll with it, especially since I already spent money on parts. I’ll still have a cheaper and better grill than a $200 one from Walmart.
Report back if you try any JB Weld, I plan on doing the same when I get around to working on it!
