I was reading about Harry Soo’s method of putting his smoke wood under the coals on the bottom of the ring. I started doing it as a test and, I have become a convert! Especially if i use barrel stave pieces they lay nicely and leave plenty of room for a full charge of charcoal. Then with the sidewinder minion method, I have found I really don’t need to do much aside from adjust vents a little, if needed.
can’t help with the gap issues aside from just let get seasoned up for a few cooks. And see how things settle in.
