Brief Description: Number 4 baffle and oil cooler, part 2
I returned to the baffle construction, concentrating first on the #4 baffle and oil cooler. I riveted the platenuts to the aft wall front face with #3 solid flush rivets, then pop-riveted the square tube plenum walls with flush blind rivets. Everything fits flush. I continued assembling the #4 baffle assembly per the plans.
I had to install/remove the baffle to/from the engine several times to check and adjust the fit.
