Claim:
A quarter sheet sander, comprising: a. a housing having first and second halves mated, an upper portion of the housing providing a handle; b. an electric motor disposed in the housing having a stator and an armature, the stator having two field coils disposed in the housing on opposite sides of the housing and bridging across the housing halves on respective opposite sides of the housing and the armature having an armature shaft on which a commutator is affixed; c. a pair of brush boxes disposed in the housing on opposite sides of the commutator, the brush boxes lying in a horizontal elevation when the sander is upright; d. a switch disposed in a handle of the housing and a cordset that enters the housing and terminates at a terminal block disposed in the housing, wherein the switch and terminal block are disposed on opposite sides of the commutator with the switch disposed on its side of the commutator between the brush boxes and the terminal block disposed on its side of the commutator between the brush boxes with the switch and terminal block of the cordset lying generally in the same horizontal elevation as the horizontal elevation of the brush boxes, wherein the edges of the halves of the housing define a vertical plane when the halves are mated together and the sander is upright where this vertical plane intersects the switch and terminal block and field coils and not the brush boxes; e. an orbit mechanism coupled to the armature shaft; f. a platen coupled to the orbit mechanism; and g. the sander having a vertical height that does not exceed 135 mm.
