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".
pic from inside showing rivets and blind rivets. Only buffed and primed flanges...so "messy" in center of rib |
whew..glad this Tip is almost done... except trimming end ~1/4 inch as marked |
