The device is a U-shaped housing comprising slidable platform embodiments providing defined and directed platform movements toward the task of shaping a rotating workpiece substantially at 90 degrees and 180 degrees to the axis of rotation. The device provides for sliding surface planes configured to accept abrasive materials and implements at predetermined angles for the purpose of trimming imperfections and truing model car wheels and axles. As an alternative to more complex machine shop equipment, the child, applying sandpaper to the platform surfaces and a triangular file or rectangular file on platform insets is enabled to effectively direct an abrasive surface which is configured at 90 degrees and 180 degrees to the axis of rotation for the purpose of truing the model car wheel and axle. To further enhance the child's participation, the workpieces can effectively be manually rotated in the slidable platform abrasion workstation device.
