Now that the parts were primed, it was time to start riveting the vertical stabilizer together. This started with riveting the rear spar and spar doubler together. The Rudder attach brackets were riveted as well. Once the rear spar was riveted, the ribs were attached and the skeleton of the vertical stabilizer was riveted together to the front spar.
Next the skin was placed over this skeleton, and the skin was riveted to the ribs and front spar. Finally the rear spar was riveted to the ribs and skin. This completed the first major component of the airplane build.
