@fedex The WSM shape is basically two kettle bowls and a midsection. The bottom flange of the midsection sits down inside the bottom bowl, and the top bowl/lid sits down inside the top flange of the midsection
That's not my experience. The outside flange of a kettle lid is the same diameter as the outside flange of the mid-section, so they rest on top of each other (meaning the lid does
not rest down inside of the midsection flange). Just got home, and tried 3 different kettle lids on my WSM. That being said, it is possible that either my WSM middle is out of round, or all 3 kettles lids could be out of round, too.
@fedex, just saw you called… was that what you were calling about?
