Step 1 & 2: When I started rivetting I noticed how the skin was a little off with the spar behind it so I algined it without a lot of force. When I finished the rivetting I saw how the whole trim tab was warpped as you can see in picture 2. I looked at the second trim tab and saw the same displacement of the skin and the spar as shown in picture 3. it took em a while but I saw that I had used the left spar with the right trim tab. So I drilled out the rivets in the spar and it was confirmed. When I used the right spar with the right trim tab the holes all lined up. I was able to finish the first trim tab before I had to get ready for Xmas.
