Tapes Done on Left Wing

We've taken the grandkids camping, been to Oshkosh and waited for the humidity to drop. It finally did on Saturday but not until an intense storm on Thursday which took out the top 80 feet of a tree leaving about 30 feet standing. The poor car took the beating but the wing in the tent behind the broken end of the tree hardly fluttered. Go figure. . Before the spanwise tapes went on, a coat of polybrush over the other tapes was needed. It helps adhesion to have the tapes filled so they don't suck the polybrush out at the overlaps. Also any bumps and rough edges of he tapes were again ironed smooth. The edges of the tapes are brushed perpendicular to the tape to feather the polybrush. It should help create a better finish.

The tip bow was taped by continuing the leading edge tape all the way around. It take a little longer to shrink it to a good fit without any cuts but I'm doing this for fun not speed.

I used metal drain grommets. I checked the parts manual to see how many were needed in case they put them on both sides of the ribs or in front of the front spar. They used 12, one on each high side of the rib at the trailing edge. They also used 2 Seaplane grommets to vent the fuel tank bay. I'll have to order those while I cover the other wing. The holes are there in the sheet metal on the bottom of the tank bay.
All the poly brush is done and tapes ironed smooth. It's time to cover the right wing.
