Abstract: This invention pertains to a power sander particularly useful in the trade of painting, specifically designed when painting louvered doors having parallel slats at an angle therein. When painting unpainted louvered doors, a primer must first be applied. To enhance the smoothness and attractiveness of the same, the primer must be sanded and up to this date it could only be done by hand because no appropriate tools where available. The tool of this invention solves the above noted problem. It is a hand held and light weight tool having an elongated blade extending from its forward end. The blade in its lateral extent is somewhat tapered but the thickness remains the same and it conforms to the space between adjacent slats. The mechanism inside the housing of the tool drives the blade in an orbital manner to simulate hand sanding. The blade has abrasive grit thereon and will sand the surfaces of two confronting slats at the same time.
