It was way too hot for most of the day to venture into the garage/airplane factory, but after the sun went down I went out and finished deburring and dimping the elevator stiffeners. Here they are in all their glory. I'm pretty sure there are eleventy kajillion of them, or at least that what it seemed like at the time.
To avoid gouging up the stiffener webs (Do stiffeners have webs? Anyway, the part that's perpendicular the flange) I ground down one side of my female tank dimple die. I didn't have this problem with the rudder stiffeners, but the holes in the elevator stiffener flanges are just a little bit closer to the webs than they were on the rudder stiffeners. And since I have an extra female tank die I wasn't too worried about accidentally munging this one when I was grinding away at it.
