Wings: Sheet Metal: LE Tip Wrap and Root Skins

I'm currently installing pieces of aluminum sheet metal to select areas on the wings. I have installed the leading edge tip wrap (not shown), which is a transition piece used to taper from the tip rib to the next inboard rib. Currently I'm working on fitting up the top and bottom root skins which are installed above and below the fuel tanks. Below are shots of the upper root skin being installed. The hole for the fuel cap and scupper was precut. I'm using a combination of clecos and hand clamps to keep the metal in place on the ribs while I transfer drill through the sheet metal into the ribs. The root skins will get riveted to the ribs.

The long aluminum sheet metal piece shown below is the leading edge wrap. This will get epoxied and riveted to the leading edge spar and ribs, following root skin installation.
