At F-704, I clamped the longerons even with the upper edge of the F-770 skin. I then checked the forward edge of the F770 to be sure that the skins extended 3/4″ past the forward edge of the longerons. I needed to trim the longerons slightly with a cutting disc in the grinder to obtain the minimum of 3/4”.
I then drilled the remaining holes connecting the longerons to the F-770 skin.
Time: 3 hours.
