Brief Description: Counter Balance and Remaining Rudder Skin Riveting
More riveting. Added the counter balance to the counterbalance rib. Had to shave off some of the lead weight towards the front edge so it would fit in between the shop head rivets. Finished riveting the spar to the skin and clecoed the top rib in place and will rivet that tomorrow. I used the numatx squeezer with the 4" yoke for the riveting. Also, final drilled #33 the aft 3 holes to receive the MK-319 rivets.
