i built one in the 1970's
i made a auto-cue in the 70's using the hawaiian sling principal, it got a lot of laughs, so 2 years ago i built another one using an coil spring in a hollow aluminum butt. just put the butt on the floor and push the shaft into the butt to cock it.
push it all the way in for breaking or push it in just a bit for softer shots. after the cue is cocked just aim and push the button that releases the shaft, it is a lot of fun.
i had a buddy that thought he could market it, so he had a patent att do some research, auto-cue or spring loaded cues have been made for almost 100 years. none to my knowledge have ever been taken serious. chuck
