Starting at the outboard I riveted the nose ribs in sequence on the right wing. Similar to the center ribs I had to drive the rivets of the sides but the middle ones I was able to squeeze.
Some time ago I ordered "The Ultimate Bucking Bar" from www.buckingbar.net. It's a small tungsten bucking bar. I was hesitant to spend $120 on a bucking bar but this thing is worth it weight in gold. I have been using it for the wing assembly and it has been just great. I wish I would have ordered it sooner.
