Main Spar Preparation

The first step in construction of the wing is the preparation of the main spar.  The platenuts for the mounting of the fuel tank are flush riveted onto the spar flanges, 60 on each wing!

Then the tie-down anchor is mounted on the spar web.  This requires the addition of spacers  to compensate for the reinforcement plates on the spar.  The spacers had a tendency to slip and I had to make an extra set when the holes were misplaced.

Time:  8 hours
