Just wanted to share my new smoker build. Spent some time on here and got a few ideas so wanted to share my progress. I used a old propane tank for my underground chimney. If you do this make sure you fill the propane tank compleatly with water and cut the top off first. Otherwise you wont live to tell about it. Cut top and bottom off and a hole for the horizontal chimney This is the fire box and pipe coming out of it. Front of fire box Fire box with chimney Smoke house framed and sided smoke house interior walls and door on. Back view front view. Still have some odds and ends to finish up but it is coming along nicely. Set a few logs on fire smoked very nice. Will post more pics when i'm done.
