I'm trying to increase the capacity of my WSM.I've come up with an idea I'm going to try out this weekend. I took a rib rack that I got from Williams Sonoma. It's too big and my ribs keep falling over. So I decided to cut out the inbetweem metal hoops. I left about 2 inch stub that I angled and filed down. I'm thinking that I can get three butts sidways in the opening. The butt will sit on the stubbs to hold it in place. I don't know if it is really needed though. If it works I'd be able to cook six butts. My butts are kind of big. I'm sure it would work with 8 pounders. This would allow you to cook almost 50 lbs of pork butt. Will let evryone know the results.
