Finishing the Leading edge attachment - 5 hours

Now for the dreaded part, installing the cherry rivets deeper into the leading edge. I had it in my mind that I was to install them from the leading edge side to the spar side, which requires you to get your hands through the leading edge rib holes.


 Its obvious that some rivets can be pulled much easier from the other direction, so that is what I did. Of course I also confirmed that I am not the only other person doing this by checking other builders websites.

But of course, some of these locations are extremely tight to the wing rib. Well a sacrificial hand riveter to the sanding station will solve this issue.





After using some gorilla tape on the makeshift riveter (so I won't scratch the primer) I then completed all of the cherry rivet installation. Worked like a charm. Next step was to use the pneumatic squeezer on the leading edge skin/spar rivets. This went extremely well and I was quite pleased when I hit quite a road block. Seems I missed a countersink on the spar for a leading edge skin dimple. Its the last hole in the line.
 


I was taken back a bit...How did I miss this. I thought I checked them all. I wasn't sure what I was going to do as everything was nearly riveted up. I thought that I was going to have to squeeze the dimple flat and countersink the skin, but this didn't sit right with me. So I posted the options on the Van's Airforce forums to see if anyone else had advice. Sure enough....it was as clear as day, just put the countersink bit on the tight space right angle drill. All I needed to do was drill out a few rivets, enough to get the drill in there.


That's enough for one day.
