I have decided to make a vertical smoker. I got a 24" diameter x 66" long 1/4" wall pipe. The one end was cut pretty crooked. So I cleaned up the one end today and started to descale it but it started to rain so I had to quit working on it. I plan on 2 doors. One for access to the fire grate and one for the smoke trays. The fire grate will be 22" below the first tray. There will be rack from 1/2" rebar 18" above that to hold a water pan that will also act as a heat diffuser. The tray holders will be spaced at 4" increments to the top. Weber grill grates will be used for the food and the the fire grate will be made from 1/2" rebar. The only thing I haven't decided on yet is where to place the exhaust pipe. I was thinking 12" down from the top. That way the heat and smoke won't go straight up and out the top. This son of a gun will be heavy, but it will be put on casters.
I have read alot here the last 2 days and have not found a lot of info on verticals. I am going vertical to save on space. If I have screwed up anything please let me know.
