positioned skins in the cradles. clecoed all front ribs to the skins. started riveting with flush rivets. Using the rivet swivel set didnt really help setting good rivets. I had to drill out a couple. Changed to flush-rivet set and it worked better, although i pushed a bit too hard in two spots (skin is slightly deformed around a couple of rivets, but no major dents. Rivets on the Inspar ribs (AN470AD4-7 and 8) are not very well set. little marring due to the squeezer. Drilled out a bad rivet with angle drill (not easy to access) and replaced with slightly better results. CHECK WITH LUCIO on the RIVETS on HS-905 Inspar Nose RIBS.
