Pat Fleming created the jump cue. First guys to use a phenolic tip was our very own John Barton with the Bunjee Jumper cues, made by Instroke at the time.
I don't know when that was but I remember a guy in the late 1980s that could jump a ball a credit card width away and jump the width of the table with enough draw to come back and scratch. It was just a shaft and he threw it like a dart, then he knocked the tip off one day and shot a few with just the ferrule and it was even easier to jump straight up!
It must have been about 1988.
I bought my house in the city, in 1987, so I know it was right around that time frame.
Some people think Earl invented the jump shot , including him , but my mentor was jumping a full ball and pocketing a ball in the corner and drawing the full table back before 1967. Earl wasn't born until 1961. He wasn't a known player because he was one of the best card mechanics in the country and only played pool to relax.
I once asked him why he didn't play pool for money and he said "I couldn't stand the cut in pay"!
He wasn't the best player I ever saw , but he had a tremendous stroke and was a stone cold killer when gambling , he just enjoyed spinning the cueball a bit too much, but he would have tortured a player anywhere near Howard Vickery's speed.
