The last bit of business is to reestablish the straightness of the spars. To do this I abandoned gravity and used a laser line tool. I set the laser up on a tripod and adjusted it until it was in line with the main spar web at both ends. I then used two screw type bottle jacks with 2x4s at two points in the middle of the wing to move the middle of the main spar up or down until the laser line was tracking the spar web for the length of the wing.
I ran a line through the nose rib jig holes to double check for straightness there just to be sure. Looked great.
The wing is now straight, square and has no twist. Ready to skin!
I’ll leave all the plumb bobs on during skinning to be sure nothing moves.
