I need some input on my reverse flow temps This is my 3rd cook on the RF and I am getting different temps along the smoke chamber, averaging 70 degrees, but on occasion has varied as much as 90 degrees. So I usual get 200 – 220 on the left and 270 – 290 on the right. My firebox is cut into the smoke chamber so approximately 6” of the top of the firebox is in the smoke chamber. The area outlined in red is the top of the firebox sitting in the smoke chamber. I have noticed many builds like this one but have not seen anyone complaining about temp variation this great. Here is what I Have tried so far to fix the problem: I Changed the position of fire from left (closest to smoke chamber), to right (furthest away from smoke chamber. I have tried various settings with the air intakes. I have tried various split sizes from 18" long 2" x 3" and 8- 10" long 2" x 3" I believe the problem is convection, the top plate of the firebox is heating up causing some serious convection. I have 2 ideas I would like to run past you guys, hopefully the first will work place firebrick along the top hoping to reduce the convection Add a sloped baffle sloping upward to the chamber inlet from the right side of the firebox I was hoping to be able to use Rutland Hi Temp Stove and Gasket cement. Will this cement work with brick A smooth black silicate-ceramic type cement formulated specifically to adhere steel to steel and cast iron. Holds gasket in place without burning off. Withstands temperatures to up to 2000°F (1095°C). Bonds fiberglass replacement gaskets to cast iron and steel. Final cure with heat of stove. Offers superior adhesive performance. For best performance bonding metal to metal. This Rutland Hi-Temp Stove & Gasket Cement is one of many top quality items in our Stove Gaskets & Cements department. If the adhesive does not hold I may weld a plate underneath, sandwiching the fire brick between the 2 layers.
