I completed some final things on the baffels. On the right aft baffle I finished up the access holes for the vacuum pump cooling duct and the pass through holes for the fuel lines. I cleaned up the edges of the holes, and drilled, dimpled and riveted where necessary. I had previously riveted cooling shields in front of the engine cylinders, with the intention of trimming them as necessary during flight testing to even the engine cooling. I decided to replace the rivets with nut plates to make any future changes easier to perform.
