275 gallon tank smoker

post #1 of 12
Thread Starter 

So, I got a 275 gallon oil tank all prepped and ready to go.  I put three doors on it.  Two horizontal doors and one big vertical door.  I'm getting some flat stock to put on around the doors to help  seal it.  I'm debating on where to put the fire box.  Part of me wants to do the traditional side mount box, but a HUGE part of me says to mount it off the back. 


After researching store bought smokers I started watching videos on "The Good One"s website ( http://thegood-one.com/ ).  I am intrigued on how they used the shape of the smoke chamber to force the smoke to circulate in the chamber itself.  I was thinking that a rear mounted firebox could utilize the shape of the tank to do the exact same thing.  I was thinking about either flush mounting the stack dampers on the existing holes (kind of like they do on their smokers) or dropping a pipe down into the chamber itself 6"-10"  Thoughts?

Here is a picture of the design I'm thinking of.  Any input?  I didn't have time to save it properly, I had to take a picture of it with my phone rather than upload it to my OneDrive because I had to get back to work.

Finally got enough flat stock to do the seals.  Anyone have any input on standard thermometers and door latches?  Also, anyone from the Cleveland, Ohio area that can shoot me towards somewhere to get expanded metal?

There is a design called a Center Feed (CF). The FB can be under or behind and the baffle plate openings to the cook chamber is on either side with the stack in the center.

I decided not to get fancy with the smoke box placement (mostly out of necessity).  Take a look at my design of the firebox.  Anyone have any input that has used a 275 gallon tank as a smoker?  I used Feldon's calculator and over sized the box, air intakes, and inlet to the cooking chamber about 20%.  I'm going to try and have this fabricated next week.  Any input would be great!  Nothing is to scale and I used MS Paint for the mock up.  Stock is going to be 1/4".


Thanks and God bless!

I have the expanded metal to make the racks now.  Anyone have any input on the placement of the metal?  Should it lay on top of the angle or rest in the channel?

If your using angle iron grates look nice when you weld to the inside of the frame.

Decided that welding the metal to the top made more sense after thinking about weight distribution. One rack has two supports, that one is the "Pig Rack".

I had to do an in-chamber smoke. 42 slabs. Going to get the third rack and firebox done over the next few weeks. Made my own rub, tasted pretty good. Going to do a couple more smokes before I sand and paint. Looking into the Raspberry PI fan/temp controller. Going to add a 120MM fan to the PI controller. Going to be a fun winter! I smoke at least 40 slabs a month and going to keep it up over the winter as long as demand keeps up. Going to do 20 turkeys for Thanksgiving. Enjoy!
