Abstract
A cue stroke practice aid is used by a billiards player to improve the player's cue stroke by repetitiously practicing the stroke at varying skill levels until a consistent stroke is developed. The practice aid comprises an elongated housing with first and second openings at opposed ends. A slide assembly is positioned in the elongated housing. The slide assembly includes a shaft, equi-spaced rails extending axially from the shaft, cue guide arms and an adjusting knob. The adjusting knob is used to move the rails laterally within the housing. This has the effect of causing cue guide arms to radially expand or contract from the axis shaft to form a tubular cavity of a desired cross dimension. The opening defined by tips of the cue guide fingers provides a target for the billiards player to practice a stroke at a selected cross dimension according to an attainable skill level.
