Brief Description: Installed Aft Center Baffle Support/More Baffling
I bent the aft center support, part 15, so that it would reach the aft baffling sides properly. I drilled, dimpled and then riveted the support bracket, R7B, to the aft right baffle, but placed it on the aft side of the baffle. The goal was to move the baffle forward a bit and this bracket did so. I used the 36" ruler to check the height of the plenum re the extended line from the forward top skin and found that the plenum was about 3/8" away from the top cowling at the closest point. I checked the two plenum inlets to see if they were even with each other using the ruler and the level. The right side was about 0.4 degrees lower (approximately 1/8") than the left side. I felt that this was acceptable. I drilled the left side of the baffling to the plenum using three inch spacing and then drilled the right side and aft right side to the plenum, using a #40 bit.
