Abstract
An adapter apparatus for use with a power operated surface preparation device comprising an upper cap positioned on a first end of a stainless steel spring and a lower cap positioned on a second end of the spring. The center of the upper cap has a threaded opening and the center of the lower cap has a threaded opening wherein a shaft of the power tool is fastened to the upper cap and a shaft of a disk is fastened to the center of the lower cap. The power device rotates at speeds up to 10,000 RPMs and the disk on the lower end adapter of the apparatus maintains close contact with a work surface while an operator exerts minimum force only to guide the power device from area to area and not to maintain the disk touching the work surface.
