LH wing, drilled lower half of leading edge skin to final size holes. Used .125 drill on the holes to be countersunk, hopefully to end up with slightly smaller holes after dimpling. Need to turn wing back over to final size the top side, then drill the wing root doubler into position, then the whole thing can be disassembled for debur and dimpling.
Lower LE skin drilled to final size holes.
Went ahead and drilled it with the LE skin tucked inside the aft skin.
