Spent a lot of time reviewing how the spar blocks and skins are installed. Did a few sample fits before drilling anything. Bent the trailing edge per manual, will have to work on the right skin a little more when I remove it for deburring. Ran a string several times to make sure I was remaining straight. There are a lot of rivets in this piece, I will have to borrow some 3/32 clecos if I want to finish before my order gets here.
