ABSTRACT:
A gimbal (22) with three critical dimensions is prepared by separately fabricating three components of the gimbal (22), and then joining the components on tooling. The steps of the method include fabricating a base ring platform (50) while maintaining a platform height critical dimension, and fabricating two brackets (56), while maintaining the bracket pivot bore height as a critical dimension. The gimbal (22) is completed by assembling the base ring platform (50) and the two brackets (56) on a tool base with an arbor extending between the pivot bores (26) on the brackets (56), while maintaining a bracket separation critical dimension, and rigidly fixing the two brackets (56) to the base ring platform (50) with locating pins (64). Three critical gimbal dimensions are thereby obtained, while reducing the cost and complexity of fabrication.
