Patent ID: 7081046

Claim:
A sanding machine for imparting an oscillating motion on an abrasive within a sanding plane and on a removable abrasive extension, the sanding machine comprising: a hand held housing; a base comprising: a bottom surface defining the sanding plane; a clamp for securing the abrasive against the bottom surface; a mounting for securing the removable abrasive extension to the base; and a motor coupled between the hand held housing and the base for imparting the oscillating motion between the hand held housing and the base to oscillate both the abrasive and the removable abrasive extension; wherein the bottom surface comprises a left edge and a right edge, the left edge and right edge being parallel and extending in a longitudinal direction; wherein the mounting secures the removable abrasive extension to the base such that a first planar abrasive extension surface of the removable abrasive extension is parallel to the longitudinal direction; wherein the removable abrasive extension comprises: the first planer abrasive extension surface; a second planar abrasive extension surface perpendicular to the first planar abrasive extension surface and parallel to the longitudinal direction; and a rigid frame coupling the first planar abrasive extension surface and the second planar abrasive extension surface to the base; and whereby the first planar abrasive extension surface and the second planar abrasive extension surface oscillate with the base.
