As I was getting ready to finalize my smoker with tuning plates I decided to purchase two sheets of metal. One for the wall where the fire box attaches too and one for tuning plates. Sorry, no picture of the side wall where i placed a sheet of metal i bought at a local lowe's. I fabricated it to where all of the holes will match up and I cut the football shape in half to decrease the amount of heat which would act as a baffle. Also for it to retain more heat. Before cutting the 1/8" steel plate into sections I placed it into the smoke chamber for measurement. I bought the piece 27"x16", this left me a 2-3" from the left side. So I left it in place. And this is where the crazy idea of a reverse flow came into play. Left side of smoke chamber Right side of smoke chamber Then I extended my exhaust pipe to the front and across to the right side. I started a chimeny full of charcoal to see the temp ranges and if it would actually work. OMG!! It did. The temp ranges within 5 degrees across the grate. I cant waite for my FIRST SMOKE!! SO..EXCITED!!
