Abstract
A dual action sander having a manually manipulated housing, a motor supported by the housing, a motor shaft balancer driven by the motor for rotation relative to the housing about a drive axis, a balancer shaft carried by the motor shaft balancer for rotation relative thereto about a second axis radially offset relative to the drive axis and for mounting a sanding device, a latch pin slidably supported by the motor shaft balancer for movement in alignment with the drive axis between unlatched and latched positions, the latch pin having a first end and a second end with the first end being engageable with the balancer shaft when the latch pin is in latched position for preventing rotation of the balancer shaft relative to the motor shaft balancer about the second axis, a manual operator carried by the housing for engagement with the second end of the latch pin and being movable to force the latch pin into latched position, and a spring for biasing the latch pin for movement towards the unlatched position.
