Brief Description: Mount main spar in jig and level
Fabricated a leveling jack for the center of the rear spar using some scrap 2x6 lumber, 3/8" threaded rod and some nuts and washers. I stretched a line from the spar root to the tip and adjusted the jack until the spar was level.
It was also necessary to fabricate a support bracket to attach the tip rib to the jig.
