Dimpled the skins. Not much fun knocking out the dimples at the very front of the skin. Added a few more scratches to the surface. A two person operation to say the least. I checked the dimple depth with an AN426 and found two at the front that needed just a bit more whacking to get the rivet to set flush. I really hated to open that skin up again. A tip to those who follow, get it right the first time. I also used the rivet squeezer to get as much of the dimpling done as possible and transitioned to the C-Frame for the remainder.
