Skeleton assembly including deburring, priming, and riveting. Tom Hathaway helped for a couple hours. We also started the plastic tip and skinned the rudder. Minimal work remains. In an effort to save time priming, I installed the piano hinge before riveting the ribs. I then noticed that there is not enough room between the hinge and some of the rivets that connect to ribs. I had to drill out all the rivets holding the hinge, rivet the ribs, and then reattach the hinge. (See "Oops" Photo)
