It's time to drill the rivet and gas line holes through the T-405, Rib and T-411. I really aganized over how to place the T405 in the rib. If you push it all the way up into the rib leading edge it fits perfect and is in perfect position according to the plans. But, skin rivets need room for the shop head. So, I trimmed a bit off the T-405 to make room for the rivet shop heads. The T-405 is riveted onto the rib after the rib is riveted onto the skin. So, I can trim more later if I need to.
Image 1 shows the trim on the T-405 for the rivets that go through the skin and rib.
Image 2 shows the distance from the T-405 and the rib reenforcment bump. The plans actually shows you this.
Image 3 shows the way the T-405 fits into the rib nice and snug.
