Hello everyone! I've only been lurking for a few days, but this site seems great. I am currently in the process of fabricating my first smoker. I got a new gas grill for my birthday, so I am turning the old Kenmore gas grill into a smoker. It may not be ideal, but I'd like to test out my smoking skills before diving in head first. I removed the side burner and mounted it inside. I plan to use a small cast iron skillet with wood chips for my smoke. Any tips? thoughts? comments? There is no stack, 2 holes on the side, and obviously the gap in the back. What should be plugged/opened? Would some type of heat deflector under the rack help to even out the heat? Thanks!
