After searching the entire internet for information on how to calculate the bob weights for balancing the rotating assembly, calling and emailing the manufacture of the balancing equipment I will be using and pm'ing multiple people, I have come up with zilch.

I did find that the bob weights are the sum of the weights of the rotor, all seals and the weight of the oil that would be in the rotor while it is running, but I haven't seen anyone reveal the weight they use to compensate for the oil. So before I lose faith in the rotary community I figured I'd give this thread a shot. So please help me out here.

How much weight is added to the bob weights to compensate for oil.
