Clecoed the skin bottom skin to the centre fuselage frame after I riveted the skeleton together. I did this so I could flute the outer F-715 ribs after drawing the centre line on the fluted ribs and backdrill through the skin. I had dimpled all the skin holes except for the ribs, so once I backdrilled the F-715 ribs it ws off with skin, debur and dimple ready to rivet the skeleton and skin together. Started to rivet on the bottom skin, surprise surprise, I even convinced my beautiful wife Virginia to shoot some rivets. A woman's touch made all the difference, shot them lovely. Managed 5 rows plus the row of rivets along the F-704 centre section bulkhead.
