You chuck the thing into the drill press, lower the head until the drum is almost touching the press's work surface, and sand away. You might attach a secondary work surface made of plywood, with a hole cut just larger than the drum, so that the drum extends a bit below that surface. That way you can sand the entire thickness of a workpiece.
