Long day. Covered sawhorses with paper dropcloth material after installing 2x4" on top of them. Performed the inital leveling of the horses. Unpacked all 4 lower wing spars and layed them out on the horses. Inspected for warpage, none noted. 3 of 4 have a slight bow but nothing that won't be corrected by rib and wire installation. Began applying rib location markings on the right wing spars.
