I got all of the flush rivets installed and all of the stiffener brackets. This is going quicker than the first spar and it looks better. I guess you do learn while doing this after all. I stopped because I ran out of 58 length flush screw so hopefully they arrive tomorrow in the mail. I am at the point where I am installing the attach block bracket. As long as I don't have any major issues. I will have no problem getting this done by the weekend is over, maybe even sooner.
