Today, I disassembled the leading edges, deburred the skins and ribs. Next I drilled, deburred and dimpled the splice plate. The splice plate qill be riveted to the leading edge (the row of holes), and nuplates will be riveted to the other row of holes to allow the use of screws to attach the fuel tank.

Today all I had assembled yesterday has been disassembled again : no more fuel tanks or Z-brackets on the spar. Then I reinstalled the leading edges and drilled them. The next weeks I'll deburr and dimple the leading edges and the skins to be able to prime everything if we have a sunny day or two before it's getting to cold.

Today, I drilled the leading edge-fuel tank junction plate, also enlarged the tie-down ring hole.



The I disassembled the leading edges for some minor adjustments. Especially the nose of the ribs needed to be worked upon to get a better position in the skin. On the first picture, there are some "spikes" on each side due to the curvature of the nose. To have a better fit, I enlarged the relief holes a bit and the small falnges could be bend a small amount. On the second picture is the end result. The leading edges have then been reassembled on the spar, waiting to be drilled.

Leading edges are assembled to the main spar. The first rib is not pre-drilled, so it first gets backdrilled to the spar. Then the fuel tank junction plate is put into position. During the next session I will backdrill the junction plate and the rib, using the skin as a guide.

Began assembling the leading edge, it was quite straightforward. Next work on this subassembly will be once the wings are on the stand.
