a vertical orientation such assemblages may also be operable in a horizontal orientation furthermore a person skilled in the art may appreciate that scale brush 704 and scale brush motor 708 assemblages may be offset from each other such that the scale brushes 704 from a first assemblage may nest between the scale brushes 704 of a second assemblage when the assemblages are retraced thereby allowing for larger scale brushes 704 referring to fig8 a cross sectional top view of one embodiment of the present invention is shown at least one embodiment of the present invention includes one or more casing diameter plates 802 configured to fit within a casing 810 the apparatus includes two or more scale brushes 804 configured to retract within a volume defined by the one or more casing diameter plates 802 referring to fig9 a cross sectional top view of one embodiment of the present invention is shown in the embodiment shown in fig8 one or more the two or more scale brushes 804 are extended beyond the volume defined by the one or more casing diameter plates 802 while rotating to remove scale from the interior surface of a water well casing scale brushes 804 may counter rotate to minimize stress on the apparatus a person skilled in the art may appreciate that while fig8 and 9 specifically show scale brushes 804 such representations would be equally applicable to an embodiment having a plurality of cutting blades as described.
