Almost ready for my first build

  1. I am getting prepared to do my first build. I have a great box that I will be using for the shell and have decided to do an insulated vertical reverse flow. I am getting materials together and one of my main concerns right now is the inside walls. Will 18ga sheet metal be heavy enough for the walls? I would really value the opinions of some of you experienced builders.

    Yep.....   18 ga. will be fine....   If you have the equipment or know someone, have them cross break it...    put the bulge to the inside....
     
  3. We built a Vertical Insulated RF,  Works great   18 ga, if fine go 1/4 " for the firebox area and you wont have any problems when you get further along and decide on you doors and seals  give me a shout and I'll post a pick and tell you what we did

    Good Luck

  4. Thanks gents. I will post some pictures later so y'all can throw any ideas at me. This type cabinet is now almost impossible to get, so I only have one chance to build it. Any ideas will be greatly appreciated.
    @gary s, I ran the original design numbers thru your calculator and am concerned about the exhaust opening. It shows that I need an opening less than 3 sq inches. I am attaching it below.

    A vertical RF does NOT use the RF flow calculator....  totally different animal.....  Here is the basic design...   flow channels should be 2-3" deep to eliminate friction loss....   width ...  Use the full width of the back for the air channels...





     
  6. Thanks, Dave and Gary. I have been ill so the build has been put on hold for a while. I will definitely keep yall up to date when I get started.
    One more question for now though. I rethought the design and have now decided build an external firebox. Easier build and more cook room inside the cabinet. I am going to order 1" kaowool to insulate the CC. Do you think it would be worth it to take time and effort to build an insulated firebox on a charcoal smoker?
