During assembly of the prototype instruments these flexures would break, but the hair line cracks were difficult to detect. It was eventually decided that the design allowed excessive strains to be imposed on the flexures and the bar assembly was redesigned to include radial and axial hinges.

The symmetrical hinge system was designed to stabilise the axial and radial balance of the oscillobar in the presence of temperature variation.

The position of the oscillobar is detected by means of the capacity changes observed between pairs of cross coupled conductor ceramic beam plates mounted either side of the bar at each end. The plates are perforated to reduce the gas damping of the oscillobar.

The oscillogyro reduces to three main sub-assemblies, which could be manufactured and tested independently before being brought together for the final assembly and testing.

The bar and hinge assembly are fixed to a motor shaft which is rotated at an accurately controlled speed. Gyroscopic forces then cause the bar to rotate in a fixed plane independently of movement of the motor shaft when the aircraft is in flight.
