Finished RH Tip Rib installation with 6 blind rivets installed while mounted on wing ( best "jig" ). Then removed Tip from Wing to install the remaining AN426 3-3.5 rivets. Good result, so moved on to LH Tip Rib...basically repeat. Drilled 19 #40 holes, with 6 enlarged to #33 for the MK319 blind rivets. Countersunk all holes - all while still mounted to Wing. Ready to deburr, prime and rivet next. Planning to trim ends of each Tip when both are "ready".
