Brief Description: Left & Right Tank Outboard Ribs Riveted
Wiped off Proseal on shop heads of seven rivets. Drilled out those rivets, because heads were crooked on skin. Still had a few rivet heads crooked, so I placed a thin washer under rivet set and squeezed them again. This made heads flush with the skin. Applied Proseal to these areas.
Wiped down right tank skin and outboard end rib with MEK. Clamped rib in vise. Applied painter's tape to rib line. Placed Proseal on skin's rib line and rib's flanges. Wiped off tails of rivets prior to riveting. Riveted rib using pneumatic squeezer. Still had a few rivet heads crooked, so I placed a thin washer under rivet set and squeezed them again. Wiped off excess Proseal on outside tank surfaces with MEK. Cleaned off all clecoes. Made about 40 grams of Proseal.
