Left Wingtip Rib, Nutplates (Wing Tips)
1.8 Hours

I shaped a couple of rock grinding bits for the shape of a countersink hole, so I don't have to dull up my countersink bits on the fiberglass.

I countersunk the holes for the rib rivets.

Then I riveted the rib in place. This caused some small cracks in the gel coat. Will have to fix later.

Then, I drilled all of the nutplate attach holes.
