Jack graciously agreed to come over and help rivet the bottom wing panels on. We worked through lunch and finished the right wing. I bucked and he handled the gun. I let the bar slip off a couple of times so I'll have reminders of riveting for the life of the plane. My next door neighbor, Robert Lee came over to offer moral support. His turn at riveting is coming. After Jack left, I installed the flap and made my first cut on the wing tip. I still haven't decided whether to use a hinge on the wing tip or screws.
