60 gallon RF build

Discussion in 'Reverse Flow' started by oaken, Aug 16, 2013.

  1. Good afternoon fellow smokers,

       I just picked up  an old air compressor tank that is 20" diameter and 36 " long with 5" domes on each end. I would like to use this as

    my cooking chamber. So I am here doing some research, before I start cutting this thing up.

    It will be a slow build as, I am in the process of moving and don't have the time, to go "hog wild" ... as much as I would like to.

    I am sure that I will need loads of info, as this progresses. But that's why we are here.

    Thanks in advance,

  2. You've come to the right place. I'm nearing completion of my ~35 gallon compressor tank build. The information and help from this forum has given me all kinds of confidence (first time welding/fabricating) and things are turning out great. 

    Use the calculator for your firebox/vent sizes, and the circle calculator from Dave's sig for the half moon opening between FB and CC.

    Looking forward to following your progress.

    Welcome to SMF!  I too am building a similar sized RF.  Measure your tank volume and plug the volume into the BBQ calculator.  Can't  post an offsite link, just google   feldon bbq calculator    That is the calc that is most used here.   It will give you the recommended firebox size and various other openings and volumes.  

    Planning and drawing it out before cutting and fabricating will save you much time.  This is the place to be for advice and suggestions.

    Looking for more on your build.....post pictures

    Ken, morning and welcome to the forum....     In my signature line are links to stuff that will help you with your build....  If you have any questions, feel free to ask the very knowledgeable members or PM me...    

  5. Thanks guys,

    Ok, I used the calculator and this is what I came up with.

    This is my first draft, I am not sure how far into the CC the chimney should extend. Also I will be insulating the FB so it will actually be bigger than originally drafted. Any suggestions are always welcome.

    (EDIT) I just found out my father in law found me another tank [​IMG], apparently larger than this one so I may have to completely rethink my plans lol

  6. I have read (and built mine this way) that the chimney should extend down to about an inch above the bottom cook rack. I have not fired mine up yet for testing but am planning to do so later this week/this weekend. Can always cut it off shorter in there... hard to make it longer. heh.

    Like your plans. Looking forward to followung your progress. I am in the process of building a verticle with side fire box.
  9. My chimney is welded to the top...not in the cc as well, and it operates quite nicely. Have fun with your build!
