A lapping assembly is described wherein a lapping process is performed to provide a flat headbox apron floor. The lapping assembly includes an eight-legged fly-style plate and a spring loaded floating driver. The lapping assembly and operation consists of attaching a spring loaded floating driver to a machine spindle of a milling machine. A lapping fly wheel is attached to the spring loaded floating driver. A coated abrasive strip with desired grit size to achieve the desired finished results is clamped in place on the lapping fly wheel. The machine spindle is rotated, thereby rotating the spring loaded floating driver and the lapping fly wheel, and the grinding and lapping of the apron floor can begin.
