Brief Description: Leveling and dropping plumb lines to square wings
The photos of this setup were lost. Basically four plumb lines were dropped from the leading edges to line up to a line on the floor, Fuselage was leveled, and consist points on each wing tip at the outer most ribs were selected and measured/matched to a commonn point at the center of the top aft fuselage near the front edge of the vertical stabilizer. Great care was taken to insure that the wings were mounted symmetrically squared with fuselage, appropriate incidence and that the sweep was square as well. I spent days relooking at the plumb lines before proceeding to drilling those next two critical rear spar holes.
