Oh Crap Moments...

This is when riveting went wrong. The washer on the inside slipped and got wedge and so the rivet got locked into an angled position, causing it not to be flush against the surface. Solution?

Drill the whole thing back out carefully and fish all the loose items out. (Notice the holes are also misaligned, which I had to fix...) So far I've had quite a couple of such Oh-Crap-Moments, not fun...
