    Abstract: A method for automatically balancing a drive shaft about a rotational axis. The method includes providing an unbalanced drive shaft for rotation about a rotational axis to determine an out-of-balance condition with respect to the drive shaft. A plurality of standardized weights or counterweights are provided wherein each standardized weight has a substantially equivalent mass. The method determines an optimal position for placing at least one of the standardized weights on a drive shaft to correct the out-of-balance condition. Standardized weights are then attached to the outer circumference of the drive shaft at the optimal position. The effectiveness of the added standardized weights is verified by subsequently rotating the drive shaft to determine whether an out-of-balance condition still exists. If the out-of-balance condition still exits, additional standardized weights may then be added to the circumference of the drive shaft.
