Just spent 3-4 days making this little beauty. The 32 pins are within .001" in length. The disk is 2" OD. The center holding rod is 1/8" OD. It's called an Attenuator and will mount on the end of the Dynasphere Shaft. See second picture where two are shown. One at the end of the shaft the other is under the little spherical Liberator and is difficult to see.
It's function it to augment or facilitate dispersion of vibrations.
