Captive nuts - the last one, really this time!

I tried my best to save this captive nut for the rear passenger wing, but it is too far gone. I started by drilling around the nut with a small drill bit at first.



I completed surrounding the nut.



Added a few more holes.



Then I moved up a drill size or two.

The reason the captive nut couldn't be saved, most of the bolt was still in!



A quick bit of welding to hold the new captive nut in place.



After grinding down the weld I filled in.



A little sanding.


One more application of filler should make the repair invisible.
