Im new to this group and to building smokers. Im a tradesman and i picked a 2ft diameter by 34" stainless steel Piece of ductwork that im trying to make in to a smoker... ive attached a photo. So I have a few plans, im going to run expanded steel across the bottom 10 inches up. Then i was going to make an adjustable air control at the bottom and a smoke stack with a removable lid on top. The middle of the duct is going to be the top (the way it sits in the picture) i have a stainless lid with a handle and 2 stainless caps for the sides... Heres where i need help. Ive ben doing a lot of reading on smokers and it seems that i would need a fire box.... i was originally planning on putting the wood chips on the bottom, bad idea? So basically im looking for suggestions on how to make this work well as a smoker. I also have a 3'X12" piece of the same kind of duct that i could attach to the side for a fire box. Heres a few questions i have, What size would i have to cut it down, how would i construct the inside, where exactly should it be mounted and how should it be attached, do i even need the fire boc....Any help/ suggestions on how to make this work would be greatly appreciated.
