Commercial Oven to Electric Smoker Build

    I recently obtained a used Southbend gas convection oven from my buddy Nick.  The unit was salvaged for parts.  All that was left was the shell.  I liked the size and durability of this stainless steel unit.  Thought it would be a great electric smoker build.

    The first thing I did was wire wheel off all the rust on the legs.  Then I painted the legs black and fastened them to the unit.

    Here's how it looked:


    Notice the hole on top?  I cut a 4" hole to accommodate a stainless steel chimney purchased from Sausage Maker:

    I did a lot of research on smoke generators.  I was about to pull the trigger on a Bradley Generator but I got a really good reference for a Smoke Daddy from a local chef that I talked to at a recent BBQ cook off.  I am excited to do some cold smoking with it as well.  I ended up with the larger Magnum unit:

    The next step was to refurbish the outer shell of the oven.  This was just cosmetic.  I obtained some diamond plate.  I retro fit the diamond plate to cap and cover the outer parts of the oven.

    This is how it looks with the diamond plate, chimney, and Smoke Daddy installed:



    Now that it looks clean, new, and full of "bling" it's time to see if it can live up to it's intended task!!  On order is a dual control PID and fin heater element.  Updates to follow.

    Lol, thanks. Doing a test run on the Daddy right now for the first time. The smoke is very very heavy. Hopefully I can dial in a more sane amount of smoke.

    The cheese turned out great. It's resting in the fridge right now. 

    I was able to get a good 4 to 5 hours of smoke.  I'm sure I could have had more if I had filled it to the top. 

    The smoke was very heavy from the Smoke Daddy.  I don't like to see that much.  I think if I find the right mix of fuel I will get it dialed in though.  Anyone here use the Magnum? 
  8. Nice score. That going to be a nice smoker. The diamond deck really snazzes it up.

    OK, I just received the "plug an play" Auber dual probe PID.  I have the probes mounted and the smoker is in the correct configuration.  My 1550 watt finned heater is wired and ready to roll.

    I am told that I should auto-tune the PID.  The directions are vague.  I understand how to get into auto-tune mode but the process is not clear to me.  The manual says I need a "water bath" (is this supposed to be a control sample of water?). Another site says that I need the smoke loaded up with meat.

    Any of you experienced folk want to clue me in on how to auto tune?

    Installed and wired 1550W finned heater with shield.  Wired with high temp appliance wiring through back into a single gang waterproof box.  Out from that is a 14 awg power cord that will go to the PID.  Also, installed two levels for the rack. Thanks to all of you for the examples and ideas!

    I did an 8lb  butt last night.  The Smoke Daddy went great.  I have it dialed in now.  Got a good 5 hours of nice thin smoke.  The secret is lump charcoal, wood chunks, and some chips.  Could have had more smoke time by adding more wood but 5 hours was more than enough.

    The PID went better than I expected!

    Here it is doing it's magic:


    Here's the last few hours of cheating:


    It's time to eat.

    Next up, Nick and I are about to cure 20 lbs of pork bellies.  Pics to follow.

    Here's the PID program I went with.  Pretty basic:


    And, here's the results!  OINK!

    WOW!   Looks great!!  Not sure how I missed this one!  I may have to pick your brain when the time comes cause I have the same controller for my GAS Build.

    Maybe this winter!!! Maybe!

    Anyhow...looks like you are gonna enjoy your new toy!
