The cherrymax rivets arrived today and I used them to rivet the F-715 to the skin in those locations where the nutplates on the F-715 interfered with setting a solid rivet. There were 4 - 5 locations on each side that took the pulled rivets. I also used cherrymax to replace the solid rivets at the forward end of the F-623 attachment. Had to drill those out to #30 and run a #30 countersink in the dimple a little to get the rivets to sit flush. They looked good after setting.
