Machine C'sunk 16 locations on QB Wings along inboard top edge (triple layer wing walk area) that builders for Vans forgot to do - after confirmation from Vans. I had installed nutplates in these locations previously. I used #30 countersink since smaller diameter pilot fits inside threaded portion of nutplates. Worked great.

Nearly completed LH Bottom Skins - waiting for Nancy to assist in order to finish last row along one rib that is hard to do by myself.
