ABSTRACT:
An assembly of a plurality of resonators is formed in which the resonators are held edge to edge and fixed relative to each other. The assembly is held together by two rigid strips mounted on opposing surfaces near the central regions of the resonators. The assembly is disposed in a longitudinal pipe which contains an abrasive material. The pipe is rotated about its axis causing the assembly to nonrandomly tumble in the abrasive so that the projecting ends of the resonators have material removed. Thus, resonators having rounded or contoured ends are produced.
