Today I began by doublechecking all of the clamps that are holding the left wing skeleton together. Then I lifted the assembly into the jig. After a little clamp manuevering, all was right except for the sag in the middle. This was solved by installing 2x4s to support the middle of the spar. A string was strung to check for straightness...good to go.
I then began to assemble the right wing; I clamped the flap and aileron drive supports into place as well as the double root rib and the tip rib. At which point I had run out of clamps! I'll have to pick a few more up tomorrow.
