The patent describes a precision mechanical centering device in which a single spring controls the return of two oppositely formed spring plates to a positive stop in each of the three axes of motion. Null adjustment is made by separating the tines of a tuning fork mounted on the same axis as each pair of spring plates until the tines contact the end surface of the spring plates. These end surfaces are positioned apart and prevented from closing by a tab of appreciable thickness which is either securely attached to or an integral part of a centrally located ground block.
