Hey everyone. I'm hoping someone out there has experience modifying a Chargriller firebox. I modified a charcoal grill from sam's club and turned into an off set smoker by adding a chargriller firebox to it. It works real well, and is built with some solid steel. However, the firebox I have is pretty cheap. The ash pan that slides in and out is warped, which causes some pretty big gaps near the pinweel damper. As you can already imagine, this makes it difficult to control heat. My problem is that my smoker is already prepped for the chargriller box, so i'm pretty much stuck with it. Has anyone had the same issue? Has anyone modified one of these so they work good? Any advice/pictures would be greatly appreciated. p.s. You can see a pic of my smoker in my profile pic.
