Hello all. I'm finally starting my smoker build! Got the steel for the structure. Will get the sheet steel when I am ready. I've modified the plans based on some Backwoods clone plans I downloaded from this site. It will be a built-in model in my backyard. I am sizing it with an extra large fire box to give me the option to burn sticks or charcoal. The smoke chamber will be about the size of a Piglet-Plus. I will post pics. shortly as I start to put it together. The first question of what I'm sure will be many is regarding the chimney size. I noticed that the piglet plus has two 4"x2" chimneys as it is simply two backwoods parties put together. I am planning on a single 6"x2" smoke stack centered in the 30" wide smoke chamber, and am wondering if I will get enough flow through the chamber, and if the smoke will be even enough. Any thoughts?
