Spent the last few days skiing in Maine. Back to work!
I ran out of clecos for the wing, so I ordered 400 more. They won't come for another day or two, so I installed all the nutplates for the under-wing access panels, as well as dimpling the access panels.
For the nutplates, I opted to: - Machine countersink the nut plate holes - Partially dimple the skins - Finish off the skin dimples by machine countersinking some of the dimple material
This way I did not have to try to dimple the nutplates, and they still fit flush against the underside of the skin.
