It was bound to happen - I'm only surprised that it didn't happen sooner. Just broke 100 hours and have been working on the rudder. I match drilled and deburred (what I thought was lightly) the stiffeners to the skin with a #40 bit. I did not knife edge any of the holes. After dimpling with the C-frame (no DRDT-2 here) I found that every one of my holes was oversized. 3/32" rivet diameter is 0.094" - all my holes fell between 0.110" - 0.115" after dimpling.
I decided to run to Spruce (only a 10 minute drive - lucky me, I know) and pick up some oversize rivets - same mfg head as a AD3, but shank diameter of an AD4. I re-clecoed everything and match drilled to #30.
My question is that is it OK for me to use the oversize (oops?) rivets for all the holes for rudder skins to stiffeners? Kind of too late to ask this question, as I've already drilled everything. I guess if it's not OK, I could re-dimple everything and use regular AD4 rivets.
The bad day didn't end there - I got my first "figure-8", dinged my first skin with the C-frame, and got a ticket on the way home.
