I noticed that you guys are using thick plate on the inside to redirect your smoke to the other side. Is the reason for the thick plate to maintain even heat?
I am wanting to build one of these and can get my hands on the 250 gal oil drums that have the oval shape. I was wondering if I mounted the tank flat instead of upright, would I have a issue with the smoke and heat covering that much surface. I figured I would have to have a couple exhaust stacks so the smoke wouldn't be drawn to one small area of the large cooking surface.
