Last night I fitted the left wing tip’s rib. This involved locating some holes on the rib and on the fiberglass, so that the web of the rib is flush with the edge of the wingtip.
I miscalculated one hole, and needed to fill it once I was done with locating all of the other holes. holes are then countersunk, and the rib deburred and primed.
Tonight I riveted the rib into position. This required the rivet gun, as the flange of the rib is facing inside the wingtip (i.e. outboard). The riveting was quick and easy.
