PAPER RETAINER FOR A SANDING DEVICE ABSTRACT An in-line sander for hand held operation and having a housing in which a rotating electric motor drives a drive shaft to rotate on a first axis, with a second axis of the drive shaft canted to the first axis and supporting a bearing thereon. A wobble housing is supported on the bearing to orbit therewith, the wobble housing having an arm extending to a platen support and extensibly and pivotably connected to a portion thereof. This orbiting of the wobble housing influences motion of the platen sup- port in accordance with the angle of the cone described by the second axis of the drive shaft. The platen support is made of a resilient material and carried by the housing on legs extending to a base portion, which legs have a low moment of inertia in the direction of in-line sanding, and a high moment of inertia normal to the direction of in-line sanding, so as to be disposed to motion in the in-line sanding path only. A platen is attached to the platen support by a key and key slot, one on each, which permits assembly when mis-aligned and retains the platen to the platen support when rotated to an alinged position. Re- silient paper clamps are provided which cooperate with grooves in the upper surfaces of posts on the platen, to retain sand paper to the platen.
