I had a sense from the “advice” of the housing inspector that a chimney cap might be necessary. It wasn’t until I experienced a few smokey blow backs, and had a couple fires snubbed out that I knew I couldn’t go another heating season without addressing the issue. Once I located the chimney cap of my dreams, I discovered that it only fitted on round pipe. What follows is the design and fabrication process of DIY stainless steel transition adapter to go from the 12″ square ceramic tile to the 8″ round stove pipe.
I used my arting & crafting powers to create a fairly accurate template of what my cap adapter will need to fit around.
Playing around with the cardboard helps me visualize how I will use one flat sheet to create the 3-d structure I am after with some forming.
