Aligning the wings...more - 1.5 hours

I decided that hydraulic bottle jacks are too unreliable to maintain the level needed for the wings. So I exchanged them for screw jacks which are mechanical and will not sag. So I set them back up and checked the lines for level. Much better. I then hung the plumb bobs looking to eliminate twists. This is not a quick process as it is a wait for the bobs to settle, they are easily disturbed with movement and adjustment.
