Here's a couple pictures of theoretical airflow with some minor modifications. This is all keeping the Okie Joe a "top down" cooker. The "baffle plate" everyone talks about is changing how it performs to be a bottom-up cooker, and many people do not prefer that. So don't just blindly add that without understand this!
Here is the Okie Joe Stock form:
Expected results
* Right 1/3 grate will be pretty much unsuable.
* Left 1/3 grate will be colder than the right 2/3. Potential "less smoke" penetration on the left side.
* Both hood gauges are going to read way hotter than grate temps.
Conclusion: This is a funcitonal design, albiet doesn't seem efficient or consistant.
Here's the Okie Joe w/ a 8" x 8" steel plate angled upwards in the cook chamber near the firebox. This is my current configuration (neighbor's recommendation):
Expected results
* Right 1/3 grate should in theory be more usable. Will confirm with a biscuit test. It's obviously still going to be a hot area, but it may be that you could start to use a few more inches of it.
* Consistent temps for the left 2/3 of the cooker. I confirmed this with my 3 racks of st. louis ribs, they all cooked absolutely perfectly with no hotspots.
* Both hood gauges are going to read way hotter than grate temps since the hot air is still traveling above.
Conclusion: This is not a bad configuration, but more fuel and less smoke flavor (
potentially....)
Here's what it would look like w/ the stack lowering mod and the plate in place:
Expected results
* Right 1/3 grate should in theory be more usable. Will confirm with a biscuit test.
* Should still get consistent temps for the left 2/3 of the cooker. In theory, less fuel is needed since hot air will be traveling closer to grate level.
* Both hood gauges are going to going to read hotter than grate temps since the hot air still rises, but the discreptancy of the hood gauges vs grate gauges should be less (right now in second config they are more than 100F off).
Conclusion: More consistant bark over a wider area,
potentially more smoke flavor and
potentially less fuel usage due to lowering the heat path which means the same amount of fuel would run hotter at the grate.
IMO, this is the type of design (any of the three configurations) I prefer vs the "baffle kit" that many people immediately jump for without thinking it through that makes the Okie Joe a bottom up smoker. There's some drawbacks to that design.
