convection plate, tuning plates, what is the way to go? i am going to get some scrap metal to make a convection plate or tuning plates for my brinkmann TMLE offset. i am also curious about making my TMLE into a reverse flow. would it be practical or worthwhile to move my smoke stack to the same side as the firebox? it looks like there might be enough room towards the backside of the cooking chamber to clear the firebox door. i've seen guys extend their smoke stack down to the cooking grate with various materials. what if i extended my smoke stack to the opposite side of the cooking grate to create reverse flow? I guess i have 3 options. 1. make a convection plate similar to that of the horizon with holes getting bigger as they go from right to left (since my firebox in on the right). http://www.horizonbbqsmokersstore.com/servlet/the-307/Convection-Plate--dsh--For/Detail 2. make a solid convection plate and move my smoke stack to the right side of the cooking chamber. 3. make a solid convection plate as above, but extend my smokestack on the insde of the cooking chamber to the firebox side.
