Another view...
The holes with the tic marks are match-drilled in line with the ribs and are in the correct location. The adjacent hole that is centered on the eyelet should not be there. A call to Vans tech support relegated the mistake to not serious. With 32 other rivets to hold the hinge, the holes in close proximity would not present a problem. As long as you have 4 times the diameter separation, you are good to go. In the photo below, those holes are less than 4 diameters apart. I chose to buy a new hinge and will re-do.
The skins get lots of clecos and the blind riveting proceeds from leading edge to trailing edge.
Blind riveting away.
View from the tip.
The next generation and the previous one at work attaching the aft skin of the stabilator. The younger one is my other "indentured" servant.
Going solo after a change of clothes and using the close quarter hand riveter. The close proximity of the hinge to the top row of rivets precluded the use of the pneumatic riveter....on the left side of the stabilator. Guess which rivets got riveted first on the right side? It wasn't the hinge rivets!
Looks like the match drilled hole could have less than 2D edge distance... Our close minded stress group would never approve that. Seems like you're all having a good time, makes we feel weak for staying out of my garage lately due to the heat. I'd love to come help some weekend, could you use another indentured servant?
