wedge until all of the wedges have been
removed and caulking of the entire horizontal

at least TWO people sub-assembling the radome, one working from the inside and the other
outside. Sub-assemble the sections of the radome on a clean, flat location that is free of rocks and
debris (ie concrete) to assure good horizontal alignment of the panels.
NOTE: Unless otherwise indicated, all nuts and bolts should be assembled with
Loctite 2760 or its equivalent.
