Concrete board smoker build

[rejjr7]

Hi all!  Brand new to the forums.   Wanted to post some pictures of the smoker I built last week.  I'm not sure what this type of smoker is called.  Its all 1" thick concrete board, holds heat amazingly well.  My wife sewed me a really nice cover for it too.

Smoking a brisket on Tuesday, can't wait.

Please let me know if you see anything in the design I can improve, and thanks!!

I had no idea when I saw the pictures in the other thread that the smoker was made of cement board.  Interesting idea, I like the thermal mass behind it.  Keep us posted as to how its working out for you, after a few more smokes.

That is amazing! I'll be really curious to hear how it holds up and works! You could make some money building these with different brick/Rock/tile surfaces if it works well!

Points for originality and enginuity! Awesome!

Awsome idea and build!!! you moght want to figure out how to add a piece of the concrete board above the charcoal box, leaving about 1 inch open around the edges as an indirect heat diffuser,and set your waterpan on top of that ,to avoid the direct heat into your cooking chamber, ant to even out temps.

Awesome idea! Nice job on the build.

Fantastic idea. Great build. I would like to see a firebox on the side .. Like a vertical smoker .

I really like this idea...  I think I'll do it.  I did a brisket yesterday, 19 hours, and it was fantastic.  I used a double water pan above the fire to serve as a heat shield but a solid piece of concrete board would work even better.

Absolutely a wonderful idea!!! I've been wanting to figure out something like this for and outdoor smokehouse. After seeing some people fail with brick and mortar this seems like such an aside answer. What on earth though have you used to make your bevel cuts and then what is holding it together??

I cut the sheets with a table saw, although a skil saw works well also.  I glued the seams together and then screwed angle brackets on to add some extra strength.  

Here's a link to another build that I borrowed from...  http://www.bbqsource-forums.com/invboard/index.php?showtopic=5268

The whole build only took me two afternoons.  Maybe 8 hours total.

What did you use for a glue? Using gorilla glue seems a little toxic to me and I know it says on their products to not be used around a heat source?

 

[rejjr7]

I used liquid nail.  I know very little glued surface is actually exposed on the inside, I don't think it would pose much hazard.  I also did two half bag burns and took it up to 400 degrees or so to make sure that anything that could be burned off would do so before I did my first smoke.

 

[wdoss89]

Ahh that's great I'm sure that is better anyways they do make a high heat glue but it's expensive. Also what brand of concrete board did you use because the stuff I looked at had the mesh stuff towards the outside of the boards which I didn't like!

 

[rejjr7]

You're right, I used the brand that didn't have any fiberglass mesh or metal in it.  I think it was the hardibacker brand.

Hey just curious what size board did you use? I see a 1/2 and quater everywhere

I used two layers of the 1/2" and glued them together.

Good idea. I was trying to think of a way to make a door for a food warmer smoker project I am working on. May try this out. What did you use for your access door on the big door. Also what did you use as your door seal?
