Today is another one of those “lots of work with very little to show for it” kind of days. The picture below shows the Wing Walk Doublers (FWD and AFT) after they were prepared. The edges were cleaned and all the holes were deburred. Because these Doublers will go between the Top Inboard Skin and Wing Ribs, these holes DO NOT get dimpled. The two pieces are now ready for Alumiprep, Alodine, and Akzo Primer.
Here is the W-00002 Top Inboard Wing Skin. All the edges have been cleaned, holes deburred, and the holes were deburred (that weren’t previously countersunk). This Skin is now ready for Alumiprep, Alodine, and Akzo Primer.
There are a couple of things to notice in this picture. First, the top left edge shows the area that I removed material from yesterday. Second, you can see an example of some of the holes after being dimpled. Lastly, if you look between the dimpled holes, you can see the slight bend (lap joint) I made in the leading edge of the Skin. As you know, the lap joint will allow the Skins to fit tighter against the Main Spar (in this case) when it is riveted.
I will post pictures of the Outboard Top Skin when I finish preparing it, but I was able to make a lot of progress on it today. During today’s session, I was able to complete the hole deburring and lap joints. I still need to finish cleaning the edges and dimple the holes.
