When a stovepipe is too small for the hole in the chimney, a bushing can be made of the kind of metal tobacco boxes that are curved to fit in a pocket. Remove the tops and bottoms of the boxes and shove them in around the pipe. If such tobacco boxes are not at hand, tin cans of any kind can be used by melting off the tops and bottoms and bending the remaining cylindrical shells into proper shape.
