The bevels were done so when I glued the 2 pieces together they would follow a 10 radius to go around the boiler. I also chamfered the 2 edges to simulate a vee into the wood like what was on the tongue and groove joint. I glued up enough to get 1/2 way around the boiler. I didn't do them all as I might have to make some of them narrower so when I get to the last piece it will fit in the bottom ring tightly.
