I'm a newbie to smoking and bbq but I've become addicted I've always loved eating bbq but cooking it yourself just makes it so much better. I've also become very interested in competition BBQ and want to give it a shot. So I bought a cheapo Brinkman offset and it works OK, but with my background in sheet metal I decided to go all in and build my own. It's 24" diameter by 40" wide with a 19x19x19 firebox that will have two inch insulation on the top bottom and sides, I sheared and rolled a sheet of 3/16, and had some end caps burnt out welded solid inside and out and then I cut out the door with a plasma cutter. I'm still wrestling with the ideas of tuning plates or a reverse flow I've read good things about both. I'll try to keep posting pics as the build progresses. So feel free to leave comments criticism or anything this seems like a great place to get advice and knowledge.
