great thread guys!! Im about to build a couple of these UDS smokers from a few barrels we had laying around at the shop. They were used to store solvents, so there is no liner in them, and shouldnt be any traces of anything left on the metal.
Anyhow, plan to start on them tonight I hope, and I will post pictures as I go. One is for me, the other for a buddy.
We will be using weber grill tops for the barrels, since they were initially closed top drums. Excited to get the project under way!!
