Hobart Convection oven build--Firebox help in Arkansas

post #1 of 6
Thread Starter 

Hi,

 

I am a long time reader, but new participant on SMF.  I would like some help designing a firebox for a build in which I am using an old commercial convection oven.  Hopefully the pics will come through--One shows the bottom of the oven, the other shows it standing upright as it will be used.

 

I am wondering if anyone else has made a stickburner out of one of these, or if there are any ideas for firebox design and getting the smoke from the box to the chamber.  In searching the forum, all I could find was an electric build out of a similar oven with a smoke generator on the side.

 

The smoke chamber is approximately a 2' cube.  (for the purpose of round numbers)

 

Thanks in advance--any help is appreciated. 

 

Adam

 It should be doable. Do you have cutting and welding equipment? What do you have steel wise to work with? Where in Arkansas are you? I'm north of Fort Smith.

Happy smoken.

Hi David.
I am admittedly no welder. I intend to take it to a local welding shop and have the fire box made, possibly prepping the oven to be attached. As far as cutting tools, I have an angle grinder, hacksaw and reciprocating saw. I was going to sort through any ideas pitched here and take my favorite to the welder to fab.

I am in Clinton. Glad to meet you and look forward to your input.

My brother suggested the following, and I am looking for comments.


I am a little concerned about the final downward turn for the smoke, but I think I will get enough draw with a 6" chimney to keep it moving.  What say the SMF readers?

Are you going to gut everything out if the Hobart? I'd be concerned putting the fire box under the unit not knowing what's in the bottom if the unit.

I'd also look at some of the calculators for firebox sizes or PM DaveOmak. In the rendering the firebox looks pretty big compared to the cook chamber. I'd be more inclined to mount it on the back or side, so you aren't having to bend down to check your fire or load. Having the downturn as it is designed may cause draft issues and make for controlling your fire difficult.

Interesting!
