reverse flow vertical smoker build.

Discussion in 'Reverse Flow' started by go4jam, Sep 19, 2015.

  1. I have researched and have found a couple different smoker designs in this forum so I have built a smoker by combining a couple different plans and added small tweaks of my own. 

     My smoker is 36" wide x 30" deep and the main body is 60" tall.

     The following is the progression of the smoker build.

     I purchased and cut 11 gauge 2 x 2 square tubing

    I welded the frame together.

    This is where I have added my own twist, I have seen the smokers with a channel in the back, I have seen them with channels on the side so I thought lets do both. I welded frame in for the top of the firebox leaving 2" gap in the back and 1" on both sides. I welded a 1/2" piece of steel for the top fire box. If you notice I have my door frames welded out of 1" square tubing and just set in place.

    Looking good, go4jam.  How about adding your location to your profile so we know where you are?

    thanks

  5. The fire box is welded. I used 3/16" plate all around the firebox.I welded all inside seams 100%.

    Looks great so far. Quick progress as well.

    I like your twist on the exhaust design. Are you planning to reverse flow all three walls?

    Keep us posted.
     
  9. There will be exhaust on all 3 side walls
     
  10. This is the internal walls welded in and door jams.The internal walls are 12 ga and the door jams are 1" x 3/8" flat stock.

  13. It is getting heavy at this point so I flipped it over, tack welded nails on the bottom to hold the insulation in place " I thought it was high temp blanket insulation but it is actually high temp board insulation", installed 2" insulation and skinned it with 14 ga black sheet steel. Being board insulation makes the worries of the insulation sagging d

    go away.


     
  14. LenDecaturAl;

    I try to but I get so involved in building that I do forget some.

  15. hardcookin,

    thank you
     
  16. So I made the internal exhaust flume and also the internal walls. The heat and smoke come uo from the side 1" gaps and the back 2" gap over the top of the flume wall and back down to the exhaust flumes. The sides exhaust flumes are 1" x 6" and the back is 2" x 6". The wall stops 4" short of the top. And I welded the interior top on. The exhaust openings at the bottom have an angle so no condensation if any will have a chance to sit. it would run back into the top side of the fire box top and evaporate maintaining moisture in the cooker. Since it is angled on the exhaust flumes I increased the size of the opening so it doesn't have a possibility of restricting air flow. the openings are 2" tall on the side and 3" tall on the back. all the interior steel in the cooking chamber is 12 gauge blk.

  17. Now I have built the exhaust flume connection point at the top of the smoker.


     
  18. I built the doors and installed. I fabricated to vents on the fire box door, they have a 2" square tubing and a slide door I made out of 12 gauge.  I put a 1/2 NPT coupling in the cooking chamber door for a thermometer.  I built the chimney and installed. I put in the racks to hold the shelving. I then taped the top door to seal the unit off and fired it up to check for any leaks before I insulate and skin the outside.




    No leaks, now I can insulate and skin the outside.
