!$^%$@^! The work yesterday riveting the W-916 tip rib in was a mistake! I put the wrong side rib in and upside down to boot with the flange side inward...no wonder it was so hard to rivet. So drilled out that mistake, cleaned it and primed it again, and set about fitting it in the correct wing tip, in the correct position. I think. Also in the other wing tip where the mistake was made, epoxied the W-938 rib. Will rivet both tomorrow.
