Hi guys I'm relatively new to smoking - have done about 4 runs on my weber kettle premium over two years and have now upgraded to an Oklahoma Joe Highland which I picked up in the sale in Walmart UK for equivalent to190 dollars! Pretty decent I think considering these things are normally a lot cheaper in the states. Looking forward to giving it a first run this weekend. Anyway, having read a few articles and watched a few youtube videos, I've made some mods to it: 1. Sealed all joints with some 1200 degrees Celcius silicone sealant. 2. Ran some self adhesive fiberglass gasket tape around the cooking chamber door. 3. Thirdly - most interestingly, I tried to make my own baffle plate "on the cheap" as I have not the skill or budget for a proper fabricated piece.. I bought a high quality cookie baking tray that fitted snugly into the first 1/3 of the cooking chamber, the part nearest to the fire and drilled differing sizes of perforations into it, the smaller ones nearer the fire and bigger on the far side of the tray away from the fire. The idea being that the tray will deflect the heat down under the tray to delay it escaping upwards into the cook chamber until it has passed under the tray and is in the middle of the cook chamber. I appreciate this is a "quick fix" on a proper full length baffle plate but hope it will go some way to re-distributing the hear / smoke and would welcome thoughts? This is what Id really like thoughts on! Lastly - I haven't bothered with an extension on the chimney exhaust to bring it down into the cooking chamber. How much will this be missed? Any feedback from experienced smokers would be great ...thanks all.
