After priming the scratched spot and modified nose rib I riveted the ribs to the front spar. The bottom ribs/spar location was imposible to fit my squeezer yoke and I tried several. I ended up using the rivet gun and bucking bar. I have had promblems before with the AN470 1/8" rivets on previous projects but I got through it without having to drill out a rivet. I give most of the credit to Avery's "snap socs" that are plastic caps that fit over the universal rivet set and protect the head of the rivet.
I used my tungston bucking bar which is great. I did scratch the primer up again where I used the bucking bar even with it taped up.
