of the imbalance a reference point 29 is marked by the human or robotic operator on an outside drum surface usually the squealer band 21 as best seen in fig3 the reference point 29 is marked along the imaginary line one hundred eighty 180 degrees from the apparent center of the imbalance this is the fourth step d in a system according to the invention then the imbalanced drum 20 is transferred to a conventional lathe 30 the lathe 30 has chuck 31 for positioning and clamping the drum 20 relative to the turning axis of the lathe the an adjustable chuck 31 may be radially shifted to a side fig4 or tilted relative to the axis of the lathe 30 fig5 the lathe 30 also has an incrementally adjustable cutting tool 32 at the production station with the lathe 30 the drum 20 marked at 29 is clamped in the chuck 31 in a determined position established by an analog for the ounce inch value recorded at 28 using the static balancer 25 which is the fifth step e in a system according to the invention concurrently the drum 20 is positioned in the chuck 31 so that the reference point marked at 29 is aligned one hundred eighty 180 degrees or opposite to the leading edge of the cutting tool 32 which is the sixth step f in a system according to the invention thereafter the lathe 30 is actuated to turn the chuck.
