First Smoker Build In Northern Ohio

post #1 of 5
Thread Starter 

So I finally got around to getting the steel that I needed to start the frame of my smoker. I am using 1x1"  steel tubing for both the cook chamber and the firebox frame. I am planning on using rock wool insulation sandwiched between both walls of 11 Ga. or 1/8" rolled plate steel. I am still trying to figure out if two walls that thick is overkill with the smoker being insulated. The wind does blow bad out at my house in the middle of a wide open field.

 

I am not even sure how to classify my smoker except as a vertical reverse flow smoker. I plan on attaching the firebox underneath my cook chamber. I know that the temps are really warm using this method, and that is why it will have two separate insulated chambers and three plates between the fire and the meat. I will have a square passage that runs along the back of both the firebox and the cook chamber, the heat and smoke will rise through this towards the back. I plan on using a downward sloping heat sync similar to a tuning plate. This will stop fat from dripping into the passage as well as direct the heat down and towards the front. The slope of the door and my two vents placed in back in theory will allow the smoke to roll from the front to the back and up ( I hope).

 

I know it sounds UN-conventional but it looks sweet on paper. It will take up a little less space and be super efficient. I am hoping to be able to claim that one log will last hours and hours. Wish me luck, and pray for warmer temps to start working in again.

Have my oldest little buddy helping me out here.

 

Starting the base for my vertical, and chambered reverse flow smoker.

 

Coming along nicely and still square!

 

It was a lot colder the second day of welding here in Ohio. I am just scribing lines on the side rails for the flush angle.

So I got some more materials together, more plate steel and my rockwool arrived. I am using 1" rockwool and still using 1/8 plate for all of the inside sheet. I am still not sure if I want to use 1/8 on the outside or something lighter to save weight. any suggestions?  I like the idea of the heavier 1/8 on the outside for efficiency reasons and how much lighter would it really be say using 1/16 on the outside? Also I spend a lot of time trying to decide on how to install air intakes and keep the insulated properties of the firebox. I have used the pit builer calculator, and all measurements are spot on. I thought of using ball valves, but if I remember correctly I would have to use four 2.5" ball valves...those are not cheap!!! But it would be easy to drill the holes and use threaded pipe, and screw them right in, also would make using a digi-q easy. But again the cost! Suggestions welcome!

Got the fire box tacked onto the cook chamber.

 

Using one inch thick rockwool, and doubled up the insulation chamber between the firebox and the cook chamber.

Fitting in the transfer sleeve before tacking it in.

 

Nice action shot the wife got of sparks flying. Using hobart .035 shielded wire and this stuff was spattering like crazy.

There she is all tacked up, awaiting more insulation and more steel.
