Drill remaining pilot holes in top rear skinFabricate from scrap pieces some temporary "legs" to have wing sit on when turned over.4 legs made. My own idea to save removing clecos or bending wing skin when turned. Used pilot holes with clecos to attach at 4 corners Accidently these came out almost perfectly level when turned...something I wasn't expecting...minor shimming required to make it level main spar and rear spar.
