I made a small refinement so that the thickness of the valve tab will no longer block the butterfly from closing all of the way. I simply used a flat file for a minute or so to make a small notch:
Now the Butterfly Air Intake can be closed all of the way:
Tcoop: See the 3rd picture in the Original Post. The lower hole is indeed below the charcoal basket (bed of coals). The upper hole is just below the top of the charcoal basket, so its position relative to the bed of coals depends on the depth of the bed of coals. In the case of a shallow bed of...
Now that it's cold out I need to use more charcoal to maintain the same temperature, but wide open on the bottom intake, half open on the top intake, and wide open on the exhaust stack is still consistently the best configuration. My charcoal basket will hold 2 Weber chimneys of Stubbs...
denden28: My convection/diffuser plate does a good job of evening out the temperature across the indirect food chamber of my OK Joe. It's certainly within 10 degrees F. It drops right in and is made from an 18" X 24" sheet of steel from Lowe's, and is easy to remove for cleaning - though the...
I am just not getting the effect I was hoping for with this experiment.
I have the airflow condensed into a column and aimed directly at the bottom corner of my charcoal basket, and I can vary the speed of the airflow from very low, to very high (26 CFM) over 6 speeds.
I have experimented...
Experimented a bit while smoking some Cornish Game Hens and Turkey Breast, and glad I didn't close off the upper opening altogether. The best heat and smoke flow seemed to be with the bottom intake wide open, and the top intake half open. It was also cold and dark out (just under 50F) so I was...
Dave, this valve plate only came about because of your encouragement to consider a way to preserve the upper air intake, and to also incorporate independent adjustability of the two original openings, so THANK YOU for helping me to better understand air intake principles before I implemented a...
The normal adjustability of the Oklahoma Joe Longhorn Air Intake still allows full control over the Lower Air Intake, and here it is shown closed:
Not too bad for a simple inexpensive and easy (and fully reversible) modification to the air intake scheme - and no welding needed as the bent tab...
OK, instead of permanently closing off the upper air intake I made a little valve out of a piece of 16 Gauge sheet metal, with a bent tab for a control handle:
Here's how it went in (Upper Air Intake Valve Wide Open):
Upper Air Intake Valve Half Open:
Upper Air Intake Valve Closed:
Thanks Dave!
The top of the charcoal basket is immediately below the opening between the two chambers (the two chambers are bolted together), so what you see directly behind the basket and partially obscured by the basket is the wall of the firebox below the hole. What you see through the hole...
