Assembled right wing. Riveted the ribs to the main spar then added the bolts and finally the rear spar. Having the ribs fluted, dimpled and primed was a big time saver as well as having the rear spar all assembled. Both wings now ready to skin but I think I may switch and assemble the leading edges next and build the cart to store the wings. They are quickly getting to be too heavy for one person to move around so the cart seems like a must have for the assembled wings.
