    RF calculator and one 500 gallon commercial smoker, huh?

    Okay, I got a change to play around with one commercial 500 gallon RF smoker from very reputable manufacturer. Did some measuring and for the fun of it tried the numbers with Feldon's. Recommended firebox size: 38500 cubic inches (has 54.4% of that, at 20933 cubic inches, insulated) Number of...

    RF sized according to calculator, major hot spot on the other end AWAY from FB!

    Hi all, I've been using my 160 gallon RF for a few years now. It was sized according to Feldon's, but generously so that every major measurement was made 1.5x what the calculator said. I also added upper air inlets later on. Here are the stats: Cook chamber size: around 5.5 feet x 24.4"...

    Diy PID & settings for pellet smoker?

    Hi there, I salvaged a Chinese made pellet smoker that had electricity problems (similar to Traeger Texas Elite). I ripped out all the electronics and verified that all the mechanics work (auger, fans and heat element). It actually had Ortech made controller, probably identical to the real...

    Is there such thing as too thick tank for smoker?

    I've been thinking about my future build... We don't have that many tanks laying around here in Finland, and I'd have an access to cheap pipe with a wall thickness of almost 7/16". Are there any other disadvantages besides weight with really thick walls? I know it'll take longer to heat up, but...

    Weird temp problem on new 160 gallon build!

    Hi there, I finally got my 160 gallon project somewhat finished. Well not finished, but it cooks :) However, there is a weird temp problem, the firebox end is considerably cooler than the far end! I though it's usually the other way around ;) All the openings have been made according to...

    How much free space do you need between racks for proper air circulation?

    Hi, I'm trying to fit three racks into my 160 gallon RF build. I'd be mainly cooking brisket flats, so I'm thinking 4" between racks will just fit flats in there. Do you think I'll run into air circulation issues with so little free space between racks? Here's a sketch of my plan: I'll...

    Firebox shape?

    Does firebox shape matter? I'm planning a build that dictates long and wide firebox, but not so tall. It would be about 40" wide, 30" long and 22" tall. Do you think I'll run into issues with the top plate burning out prematurely? I think I'll go with 1/4" steel for the firebox. Also...

    What's the best way to cut a tank?

    Hi there, I have a new tank that needs to have the end cut off for the FB end. What's the best way to cut it straight? I have a plasma, but I'm having a hard time measuring/marking a straight line on the tank. I don't think the original end cap weld is even remotely close to straight. I've...

    Short and fat 250 gal. reverse flow, advice on adjusting parameters for airflow?

    Hi, I recently got a new tank, which is around 35" in diameter and the straight part is 51" long. I'm going to cut the FB end off and weld a new end plate, since I've found out that it's much easier to work around that flat end. Naturally I'm going to keep the other end to allow for good...

    What kind of smoker from an old fat round oil tank?

    Hi, What kind of smoker would you build from an old oil tank? It's really fat, I'd say the diameter is around 40" and length maybe a bit more. Would it work as a RF build? I think I could easily fit 4-5 racks in there, just concerned that the temp difference could be huge from the bottom to the...

    Is galvanized pipe fine for drain?

    Yeah, I know it's not recommended, but there shouldn't be temperatures high enough to do any damage in the cooking chamber, right? I'm asking because it's impossible to get simple black threaded pipe here in Finland any more! It's ridiculous, a couple of years ago it was everywhere...

    Firebox to CC opening not quite all the way to the top?

    Hi, I almost started tacking up my firebox when I realized something. I haven't cut my FB to CC opening all the way up. I did it with cnc plasma beforehand, so there's a rim of around 2/3" on top. Here's a Sketchup model how I cut it: Will this be a problem? I know some hor air could get...

    Fixing doors that have sprung other way?

    Ok, It really looks like my doors have sprung inside from the corners (most gap on the middle) . I tried using a bottle jack, but it was really impossible to get the door to sit "upside down" on it. Any tips? A sledgehammer?

    Intake styles?

    Hi, I'm currently building my first RF smoker out of 160 gallon tank. Everything has been sized pretty much by what the calculator said, my FB is going to be around 108% oversized and the throat is also a bit oversized. I need to cut my FB plates soon. But I can't really decide on intake...
