The aft tips of the top skin of the vertical fin went on pretty easily and look pretty good. But the top rib, that ties it all togerther, is giving me some trouble. So far I am not able to get the proper curves in the top rib. I have made three attempts but none of them are really fitting right. I was getting a bit frustrated with these failures, so I decided to take a day or two off and come back to it later.
