Today was a very prouctive day. With help from Ken Dunn we were able to Match drill the entire skin, ribs, and spar. As well, we dimpled all the spars and asembled the right elevator Horn and attatched it to the spar and inboard rib. The main spar was dimbled with the pnematic riveter and not counter sunk due to the thickness of the spar, I was afraid of making it to weak if I countersunk the holes too deep. It turned out very well and the rivets should not be a problem.
