ABSTRACT:
A pool cue tip conditioning device has a striker plate carrying tip-indenting fingers on its bottom side, the plate located for being driven into a pool cue tip to indent the tip without damaging it. The striker plate is driven by a plunger controlled by a return spring. A plug is located above the plunger, the plug having an aperture in a bottom surface for receiving the tip of the plunger when the post of the plunger is centered. The plug is held off-center by an aysmmetric return spring which allows the tip of the post to become centered and to move upward into the aperture when the striker plate is moved upward by insertion of a pool cue. A work spring stronger than the return spring then forces the plug downward, slamming into the plunger, which drives the striker plate into the cue tip.
