Not at all a dumb question. I can stare at the rib drawings and watch them alternate between pointing into and out of the page like some of the optical illusions in my old college psychology texts.

In this case, the sides are bent towards us, and this piece nests inside another angle. I used the countersink bit in the hand deburring tool to make the countersink, and it worked great! I've since used it to clean up a couple of machine countersinked holes that were off by a couple thousandths.

Now, getting the rivets to stay put while I squeezed them, that's another story. Let's just say I got lots of experience drilling out rivets between this and the nut plates on the vertical stabilizer rear spar. To digress, however, it's really refreshing doing a project with no deadlines in which taking time to fix problems doesn't put you behind a schedule.
