8. Roughly align panel by moving threaded rod up or down with nuts on truss.
Sight the outer corners of each panel using the theodolite and data provided
in Table 2-3. (This will minimize the final adjustments.) Set the outer edge
elevation angle to 87° - 26’ - 20”. Set the azimuth of the lateral edge of the
panels to 0° - 02’ each side of the 15° increments. Fully tighten the adjusting
nuts.

9. Repeat steps 5 through 8 for the remainder of the panels on the inner row,
spacing panels 1/8 inch (0.32 cm) apart.
10. Starting at a spar tab position, place left spar panel (item 1) on threaded rods
spaced 1/8 inch (0.32 cm) out from inner panel. See drawing sheet 1.
11. Secure panel to rods using four washers (item 9) and four nuts (item 10).
12. Align panel surface flush to adjacent inner panel by moving threaded rod up
or down with nuts on truss. Align outer corners using theodolite. Refer to
Table 2-3.
13. Place right spar panel (item 2) on threaded rods at next clockwise position.
14. Secure panel to rods using four washers (item 9) and four nuts (item 10).
15. Align panel flush to adjacent panels by moving threaded rod up or down
with nuts on truss. Align outer corners using theodolite.
16. Place outer panel (item 3) on threaded rods at next counterclockwise
position.
17. Secure panel to rods using four washers (item 9) and four nuts (item 10).
18. Align panel flush to adjacent panels by moving threaded rod up or down
with nuts on truss. Align outer corners using theodolite.
19. Repeat steps 16 through 18 for the next four panels on the outer row.
20. Repeat steps 10 through 19 three times to complete outer row of panels.
