Built a temporary holding fixture onto my work bench and aligned it using the laser. Installed the substructure into the skin and checked it about a thousand times for twist and spar straightness. Once everything appeared in order, I drilled Spar into skin and clecoed the assembly. I will drill the ribs in the next build session.
Checking alignment after fixture was checked empty
Ready to drill spar
Spar drilled. If there is any twist...it is locked in now....
