Dimpled fuselage cage with squeezer and 120 degree dimple die then tested with test coupon for proper depth. No big deal in this dimpling process of the steal cage. Going with flush rivets. After everything was deburred and dimpled I slid front and back fuselage back together to be bolted up but forgot to install push rod tube tunnel side cover in the baggage area. So I pulled them back apart and installed tunnel side then slid front and back section together again and installed bolts per instructions.
