Brief Description:  Right Wing - Leading Edge and Main Skins

Today I riveted the joint plate and W-408 rib to the right leading edge, and riveted the leading edge to the spar. On the leading edge rib flanges to the spar, I used MSP-43 rivets from the forward side of the spar on the outboard three ribs, and MSP-44 from the aft side on the inboard three. I've read of some concerns with dissimilar metal corrosion between the stainless shank of these rivets and the aluminum structure. Some use the LP series of aluminum blind rivets, but I chose the stainless/monel rivets for their higher strength, and installed every one with wet primer.

After completeing the rib to spar riveting on the leading edge, I had Karen come out and help me dimple the main skins. I wanted to get these done in the daylight, as the lighting in my shop isn't as good as it could be, and the light of day helps me with depth perception in getting the holes lined up with the dies. I'm hoping, if it isn't too cold, to get some help and rivet the top skins to the skeleton tomorrow.

After that, I squeezed the rivets in the very most forward holes in the top and bottom flanges of the eight main ribs behind the tank. The rivets in these holes will end up under the tank skin, and only go through the spar and rib. These need to be installed before the main skins are permanently in place for good access.

I finished up the day by squeezing all of the skin to spar rivets to complete installation of the leading edge.
