I finished double flush riveting the trim tab trailing edge and these are the results (I hope this photo comes through). The shop head is sitting about 0.030 in. proud from the skin.
Before I rivet the TE on the rest of the elevator tomorrow I'd like some confirmation that this is acceptable or if it needs to be flush with the skin. My main fear is cracking the rivet. I made three passes on each rivet to get this far because I was concerned about keeping the edge straight. So far the trim tab TE is straight to 0.020 in. along the entire length.
On a related note, the plans call out using a AD3-4.5 rivet. I had another location that had to be double flush riveted and I substituted a half size small length rivet and got great results. It seems that using a AD3-4 here would be a bit easier to make it flush on the shop head.
What are your recommendations? Should I make another pass to try and get it flush or just leave it alone? Should I use a AD3-4 on the main TE?
