Cap strips, Through step 71

Right wing taking shape! I installed the cap strips on the #5 rib, the
#1 rib top and bottom. The #5 rib was most problematic and took most
of the day, because the manual calls for flush rivets to be squeezed
into place, and there's little to no room for the squeezer - left some
to be desired, but came out pretty ok in the end. #1 rib was much
easier as the manual calls for cherry max flush head rivets to be
used, and countersinking instead of dimpling, a much better choice and
a better result too.
