Drilled out about 7 rivets in the vertical stabelizer spar because of stress lines I placed on the machine head. The bottom of the spar had a hole that I messed up a few days ago. I could not rivet the hole so I drilled two adjacent 3/32 holes, machine counter sunk those rivets. Placed the skin over the vertical stabelizer and began riveting. Riveted the front inspar ribs and began riveting the spar.
