The rivets located near the main spar are difficult to rivet with only on person. My friend (Greg) and his oldest boy (Jack) flew to KEFD to spend some time checking out the status of the wings. (KEFD is 10 minutes away.) Jack jumped right in and started helping out with placing rivets and pulling the trigger on the rivet gun. Greg switched from the gun to the backing bar so he could get a feel for how things worked.
With the both of their help we completed Section 16. Jack enjoyed helping but just like all kids was ready to get back in the "flying" airplane and zoom back home.
