Patent ID: 7725977

Claim:
A surface preparation device for preparing material having a remote surface and a spaced apart proximate surface comprising: a remote surface preparation assembly having a body with a coupling element and a first end for contacting the remote surface for preparing the first surface; a base having one or more support surfaces for contacting the proximate surface and a view-through portion; a drive head including an elongated member having opposite ends and a centrally disposed motor connection point, the elongated member having a coupling element at each of the opposite ends providing a magnetic attractive force for attracting the remote surface preparation assembly coupling element thereby coupling the remote surface preparation assembly to the drive head for remote actuation, wherein at least one of the drive head coupling element and the remote surface preparation assembly coupling element is a magnet; a body housing movably connected to the base and having a handle portion for gripping the surface preparation device during operation; and a motor disposed within the body housing and connected to the motor connection point rotating the elongated drive head within the base thereby enabling a user to see at least one of the proximate surface and the remote surface through the view-through portion and the rotating elongated drive head during operation.
