ACTUATOR FOR IN-LINE SANDER 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 bearing housing is supported on the bearing to orbit therewith, the bearing housing having an arm extending to a platen support and extensibly and pivotably connected to a portion thereof. This orbiting of the bearing 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 aligned and retains the platen to the platen support when rotated. Resilient paper clamps are provided which cooperate with grooves in the upper surfaces of posts on the platen, to retain sand paper to the platen.
