Drilled out a rivet in the rear spar and flap gap seal. The tail fractured when I squeezed it. Because of the restricted access, decided to replace it with a CR3212-4-2 (I know, that hole wasn't supposed to be dimpled/countersunk but I got carried away ). Unfortunately, I had trouble with this one, as well, and I need to remove it, too. I suspect it will spin on me when I try to drill it out, particularly considering that the shank hasn't been fully expanded. Somewhere, I've seen a tool for drilling out pulled rivets that holds the head of the rivet from spinning while it's being drilled. Can anyone tell me where I can find one?
