VS prep
Prepared VS ribs and spars. Such a simple phrase, but it takes so long. I disassembled everything, then deburred all of the holes in the ribs and spars, followed by smoothing and deburring the edges. I dimpled the holes for attaching the skins and for the area on the rear spar that attaches to the fuselage. Counter-sunk the holes in the lower rear spar stiffener. Also smoothed the edges of the stiffener, which took a while.
This shows how the bottom of the rear spar and stiffener are dimpled and countersunk to allow for flush head rivets where the VS attaches to the fuselage.
