With all of the parts completed it's time to start assembly of the fuselage. Alignment and squareness are the keys here. I reconfirmed the flatness of the table before starting. No problems there.
I then had to shop around for two aluminum carpenter squares. Most are steel so it took a while to find them, but Lowes had them. I set these for the 40" dimension the drilled and clecoed them together. I also measured and marked the table for the dimension and attached two wooden cleats to maintain the dimension. The entire section is built upside down initially.
