I bought an RV 4 project and both wings are assembled with the LE and top skins riveted in place. The bottom skins are drilled and dimpled and cleco'd in place. The wings are on a rack held by the spar on one end and the bit of spar web that sticks out the other end of the tip rib. If I rivet on the bottom skins in this stand, can I reasonably expect the wing to come out as straight as it was in the original jig when the bottom skins were drilled? Or do I need to put it in a jig and hold it straight for riveting?
