Abstract
A sander can include housing, and a motor assembly in the housing. The motor assembly can include an output member. A platen can be driven by the output member. A user feedback assembly can be coupled to the housing and have a sensor assembly, a controller and an indicator. The sensor assembly can be configured to sense a parameter that is related to a magnitude of a force transmitted between the platen and a workpiece and generate a signal in response thereto. The controller can receive the sensor signal from the sensor assembly and control operation of the indicator in response thereto.
