Abstract

A three-dimensional balance assembly is provided. The assembly includes a center shaft, two or more eccentric weighted shafts encompassing the center shaft and a first and a second locking mechanism that lock each weighted shaft into any rotational location. Each eccentric weighted shaft includes at least one eccentric weight. The two or more eccentric weighted shafts are independently rotatable around the center shaft to balance the assembly in two dimensions. The center shaft includes a first and a second bore extending inwardly from each end of the center shaft or a single bore all the way through the shaft. The first and second bores are adapted to receive and secure one or more axial weights and balance the assembly in a third dimension.
