mounting bracket, template arm, drill template, and setting data for
alignment are located in Alignment Kit #516212.
1. Verify that the theodolite is still level with respect to the panel mounting
ring, at a height of 16.850 inches [42.799 cm].
2. Pin the template arm to the tab on the slip ring below the theodolite
mounting plate.
NOTE
The splice plates and bushing plates must face away from
the surface of the reflector. Any kinks in the template
should be smoothed in order for the curve of the template
to follow the curve of the reflector.
3. Attach section 1 of the drill template to template arm using two #8-32
screws. Attach section 2 of drill template to section 1 using two #8-32
screws. Section 3 of the template will not be used for the 9-meter reflector
alignment.
4. At 3 inches to the left and right of each radial panel joint, drill #13 or 3/16"
holes in the panel surface using the 3rd, 4th, and 7th drill bushings in the
template. Assure that no burrs protrude into the holes or above the panel
surface.
5. Install a theodolite target into each of the drilled holes in the reflector, fully
seated. The target should be rotated in the hole so that the flat surface
containing the white diamond shapes is facing toward the theodolite.
6. Set the theodolite elevation angle at the appropriate value for the target row
being adjusted. The angles are given on a data sheet packed along with the
drill template in the alignment kit. If the data is missing from the kit, the
values in
Table 2-4 may be used to obtain a reasonably accurate setting.
