Understanding Cue Shaft Flexibility​

To understand why a whippy cue shaft can create more spin on the cue ball, we need to break down several key concepts related to cue mechanics, including flexibility, energy transfer, and tip contact.

1. Definition of Whippy Cues​

A whippy cue is characterized by its flexibility or lower stiffness compared to a stiff cue. This flexibility allows the shaft to bend during the stroke, which can influence how energy is transferred from the player’s stroke to the cue ball.

2. Energy Storage and Release​

When a player strikes the cue ball with a whippy shaft, the following occurs:

  • Compression: As the tip of the cue makes contact with the cue ball, both the tip and the shaft compress slightly due to the impact.
  • Energy Storage: The flexible nature of a whippy shaft allows it to store some of this energy as it bends.
  • Release of Energy: Once the initial compression occurs and the cue ball starts moving, the stored energy in the flexing shaft is released. This release can add additional speed and spin to the cue ball beyond what is provided solely by the player’s stroke.

3. Increased Tip Contact Time​

The flexibility of a whippy shaft can also lead to an increased contact time between the tip and the cue ball:

  • Longer Contact Duration: A flexible shaft may allow for a longer duration of contact between the tip and cue ball during impact. This extended contact time can enhance spin because it gives more opportunity for friction between the tip and ball.
  • Enhanced Spin Generation: With more time for frictional interaction, players can impart greater sidespin or topspin on their shots.

4. Reduced Squirt Effect​

Whippy cues often have lower end mass compared to stiffer cues:

  • Lower End Mass: A lighter end mass results in less squirt (the lateral deflection of the cue ball upon impact). This means that players can hit with more precision when applying spin without worrying as much about unintended deflection.
  • More Control Over Spin: With reduced squirt, players can better control where they want their shot to go while still applying significant amounts of spin.

Conclusion​

In summary, a whippy cue shaft creates more spin on the cue ball primarily due to its ability to store and release energy effectively during impact, allowing for longer contact time with enhanced frictional interaction. Additionally, its lower end mass reduces squirt, providing greater control over spin application.
 
Love to hear this nimrod explain how super-stiff cf shafts are also low delection. Its END MASS, mainly the last 5-7" of the shaft, that determines its deflection properties. Shaft flexibility has no effect in the areas the op described. Hope he's not selling cues and feeding people this bs.

How 'bout a big NOPE. None of your conclusion is even close to being correct. Where do people hear this shit?????

These are not my conclusions....
I just found the reports from doing a little online research.
I'm thinking the scientists and professors doing these studies have a little better understanding of physics than you do??
 
There’s a simple test to compare the amount of spin created with different tips (or shafts, tapers, whatever):

1. Use a striped ball as your “cue ball” with the stripe vertical and aligned with the shot.

2. Shoot the “cue ball” from either spot (head or foot) straight into the side rail (at the middle diamond) with maximum sidespin. Check the chalk mark to confirm you hit right on the edge of the stripe - only count the shots that you did.

3. Shoot just hard enough so the ball rebounds to the near side rail.

4. How far to the side did it rebound?

Is this chat gtp or some type of chat "AI"? It's notorious for being wrong but provides a convincing text block, even if completely wrong.

If you hang around for a little bit, you will discover that there are professors and scientists right here.
 
On the relation of shaft stiffness to spin...

Many years ago, I got a Schuler carom cue. Very stiff, conical taper. Boy, did it spin the ball. In hindsight I attribute that to the somewhat smaller tip than I was normally using at the time and that I was spinning carom balls. Very, very stiff.
 
I don't know you guys but every time I play with a Meucci from different owners' I can draw the crap out of a ball. They all do this and its almost to the point where its a signature/characteristic of their cues. I don't know how to explain this weird phenomenon. You hear it from people that have shot with it too. A lot of these guys either passed away or no longer play pool. I'm in my 40's so I may be the last of a dying breed to remember Meucci during its popularity.

Maybe Bob grew his own wood. LOL

This isn't a new topic because when I searched Meucci on Google it shows me a lot of threads on this subject matter from AZB.
 
So this is the difference between AZB and the other social media outlets such as FB, Youtube comments, and Reddit. On here, if someone posts BS, they get called out on it. We have this thread and the tip hardness thread, both by the same OP. If he were to post the same on the other social media platforms, he'd probably be called a hero on those.

The same thing happened with the guy last week that started a directory of pool rooms website. Sure, it is a very well meaning idea. But here on AZB we've seen it all, and know it won't work. On the other platforms, he was getting praise and missing data to complete his list.
