Finished riveting bottom of right Horizontal Stabilizer. Had to drill and re-rivet 5-10 rivets. Need to work on my buck technique and speed. Seven hours seems excessive, but I'm going nice and slow trying to avoid any extra mistakes. Might need to slowly increase the air pressure for the gun to speed things up, but need better skills first!
Finished all Forward spar rivets. Only about 3/4 of the squeezer rivets remaining.
