ABSTRACT:
An apparatus and method for smoothing unfinished surfaces is disclosed. A sanding head having a formed abrasive surface is secured to the mandrel of a rotational tool. A user is able to finish and smooth irregular and fanciful shapes cut into wood or plastic products using power from the tool where previously such operations were performed by extensive hand sanding or polishing. In a second embodiment of the invention, the sanding head is configured to conform to the size and shape of standard router heads currently available on the market. It also uses the standard router guide bearings, which allow it to be used to surface the area that a router has previously cut. In another embodiment of the invention, a standard sanding roller can be mounted on the rotating tool in place of the sanding head for appropriate applications. In yet a further embodiment of the invention, a standard paint roller may be mounted on the rotating tool to enable the user to perform polishing operations on unfinished irregular surfaces.
