Platform Assembly
1. Slide the coil into the slot in the right side of the
platform.
2. Secure the coil with the ¼ x 20 brass screw that is
stored in the platform.
3. Remove the six 6-32 brass screws from the right
side of the platform. Slide the left side of the
platform into the right side, with the right side
overlapping the left side.
4. Secure the right side to the left side using the six
6-32 brass screws.
