Detail of the strapping necessary to pull the forward wing skin into place. Drilled the pilot holes in the forward ribs.

After drilling the pilot holes in the ribs, the forward skin is opened up again to dimple the skin and ribs for flush rivets, using the Sonex super-simple dimple die and the pneumatic rivet tool with 20psi, using a rivet for the dimple die mandrel. The resulting dimple is nearly at #30 after stretching the skin, so the holes were deburred and the wing reclosed with 1/8" clecoes.
