Hi I'm looking into modifying my char broil horizontal smoker/grill model CBBA-2750/z, I got it at target. But I was thinking about doing a complete overhaul on it. I was wondering if it would be worth while to modify it to a reverse flow smoker our just put a nice buffer plate in it? And what thickness would I use for the sheet metal. I was also planning on welding the entire lid shut because the whole half barrel opens and is no where near air tight, and then cutting a smaller more tight opening for the lid. I was also going to put an ash drop hatch on the fire box. I was actually wondering if any body could give me advice or comments or questions about the process. Any help would be greatly appreciated. Thanks.
