Today I worked on riveting the skins for the top of the right wing. In progressively installed clecos and pulled rivets until all were done. I left the last row at the wing tip as pulling the tip skin around seems to require a fair bit of force and I would rather wait until I rivet the other side. There was on rivet that when installed interfered with the angle at the tie down bracket. For this rivet, I used the manual puller and kept some pressure on the rivet so that it would be drawn in as I pulled.
