As some of you may know I've been building and cooking on Drum Smokers for a couple years now, and have been using Weber kettle lids on some of them. JD McGee has dropped off a few of the bottoms from the kettles he's used the lids from.
I saw this link on TVWBB site and have been following the thread. It's called the Cajun Bandit and it can turn an ordinary 22.5" kettle into a WSM.
