    Built another patio model over the weekend for another buddy.  Pretty much the same as the last one I did just a little bigger.  This one has a cooking area of 18"x30" with a wrap around shelf.  Here is the pic.

    That build looks outstanding.  you can do some wonderful metal work.. but I have a couple questions.

    How exactly does a "Double Reverse Flow" work?  What are the benefits of such a setup?

    I understand the reverse flow smoker design. and I understand the benefits of such a setup.  but a Double?

    Cooler smoke?  Draws better?  I'm kinda baffled! [​IMG]

    With the firebox centered on the cook chamber the smoke and heat rises and encounters the baffle plate where it then turns left and right.  I add a piece of angle welded to the baffle centered on the firebox opening.  This is a stiffener to combat the direct heat and also helps direct the smoke.  It is welded in a V pattern.  Once it gets to the ends of the baffle plate it rises and enters the cook chamber.  By placing the exhaust on center and at grate level the smoke and heat will rise and roll at the top of the cook chamber before following the draft and exiting at grate level.  This was all theory until we built the first unit and tested it.  It works very well.  I'm not sure it would be considered a true reverse flow, but rather a modified reverse flow (shorter path).  Temps are perfectly even across the grate after the unit comes up to temp.  Another advantage we have seen with the center mount is more effiecent heat transfer to the cook chamber.  Temps are fairly easy to control with this unit.  I'm no expert, but so far the units have been performing better then expected.
