Assembled my new Ok Joe Highland and used Permatex Ultra Copper to seal the seams. Waiting for the Nomex tape to arrive so I can seal the doors. Due to rain, I haven't seasoned the smoker yet. I plan to do an initial burn to burn it out and then wipe it down real good before spraying Flaxseed oil inside and doing a seasoning burn. I have a question that might be obvious or just dumb. Does anyone know the purpose of the extra sleeves welded to the door hinges might be for? It almost appears like it could be used to attach some extra shelves. There's two sleeves on the main smoker and two on the firebox, attached to the hinges. Come to think about it, maybe it's just extra support for the small welds holding the hinges.
