I'm looking at building a new smoker/smoke house in the spring and am looking for ideas. I currently have an small old woodstove that I have piped into a tin 30"x30"x40" "smoke house". The woodstove has seen better days and I am looking at building something more permanent. I was thinking of cinder blocks for the lower portion and cedar for the top portion. I'm kind of leaning towards using the burner from my turkey fryer as I think I will be able to control the temperature better than with a wood fire. Has anyone done anything similar to this? How large of a box with the burner from a turkey fryer heat and how long will a 20lb bottle last?
