Determine whether you need a single plane or a two plane balance. Typically, if the rotor width is less than half of the diameter a single plane balance will be sufficient. If the width is more than half the diameter, a two plane balance may work best. 10. Balancing by angles or blades. Historically, balancing was calculated in degrees.
