ABSTRACT:
A sander (20) for a bullnose cornerbead (500) includes a body (22) having a bullnose-shaped concave surface (24) having a second radius of curvature (R.sub.2) greater than the first radius of curvature (R.sub.1) of the bullnose cornerbead (500). A flexible pad (26) is disposed on concave surface (24), and forms a third radius of curvature (R.sub.3) which is greater than first radius of curvature (R.sub.1), and less than second radius of curvature (R.sub.2). Pad (26) does not fully extend to the edges (34) and (36) of sander (20), thereby leaving two gaps (38) and (40). A sheet of abrading material (700) such as sandpaper or emery cloth is clamped adjacent to flexible pad (26) and around concave surface (24) of sander (20). A handle (800) is connected to a pivotable connector (48) which only pivots in one plane (50).
