Today I flipped the wing over so that it was right side up. Next I started to explore how I could install the root doubler and wing walk for drilling. I removed the clecos from the wing walk area and then I marked the 5/8 overhang onto the doubler for the left wing. I turned out easier to install the doubler and then measure the overhang. The doubler seemed long by about 1/4 inch. I’ll need to check the yahoo groups to see if this is the case. After I think I am ready to start marking and drilling the holes. Checking the plans indicates there will be excess.
