Abstract: A golf putting practice guide that holds a golf club in a putting position, and allows a golfer to perform putting strokes about a single axis that passes between the shoulders of the golfer. No wrist rotation, cocking, or any other additional freedom of motion is permitted by this device. A vertical support holds a pivot bearing at about head level, and a guide arm depends from the pivot. The lower end of the guide arm firmly clamps a golf putting club shaft without blocking the golfer's view of the club head. Adjustments are provided to orient the pivot axis angle and height so that a perpendicular line drawn from the club head to the pivot axis meets the axis between the golfer's shoulders. The club head then swings in a perfect circular arc in a swing plane that passes through the golfer's shoulders.
