Abstract
An apparatus includes a sleeve sized to receive a bar, the sleeve having a nub. The apparatus includes a movable assembly including a spindle, a drive axle to receive the chuck of a drill, and a bracket, the bracket sized to fit over either of the bar and the nub. A power relay of the apparatus receives a power cord of the drill and applies power from an electrical source to the power cord of the drill upon the operation of a power relay switch. A retainer, separate from the movable assembly, retains a drill power switch in an ON position.
