I ended up drilling out the perfectly set rivet. I though for a while on how to fix the missed dimples. I was really reluctant to drill out all of the rivets in the rib that I had set. I finally had an idea of using the tight space dimple bar with the rivet set on the gun. Of course I was very concerned about marring the exterior skin. I figured that if I used the tight space rivet bar with the bucking bar, it would be very similar to the standard bucking process.
Sure enough... using this setup with the pressure on the gun dialed down a little. The day was saved and I very easily dimpled the two holes. You would never know I missed them.
A few more hours and I was nearly complete the right wing.
