Is this correct?

I thought that the amount of the shaft's mass "involved" in squirting the CB isn't changed significantly by its flexibility/stiffness due to the brief contact and relatively slow transverse wave speed through the shaft. In other words flexibility/stiffness doesn't affect squirt much.

That is true in general in most comparisons; however, if comparing a cabon fiber shaft to a maple shaft, the "endmass" dependence on stiffness can be an important effect.

Yup kind of like a wet noodle ,

Now that's not the part that doesn't have to be true. Just sayin...

I typed before reading the rest of the replies. Apparently others mentioned that a stiff shaft CAN HAVE THE SAME PROPERTIES AS a LD shaft.

If a LD shaft deflects a lot (and the cue ball only a little), that means that the shaft is somehow bended or displaced ( and it cannot be displaced because is attached to the butt, that you are holding), so I cannot understand how stiffness has little effect on cue ball squirt, even more, and how a Mezz HPII or wx700 can produce so small squirt being extremely stiff. It's a mistery for me.

Agreed, all I know is I shoot a hell of a lot more consistent and put the CB where it's needed for a run out easier with my WX700 than any other shaft/cue I've shot with.

If anyone wants to knock LD property shafts, more power to you, to each is there own. Only kind of shafts I dislike is glued together junk, but thats just me.

Yeah, the two posters above (wet noodle) clearly thought that too lol. :rolleyes:

Well, here's something to consider.

It's true that the term LD isn't really correct. It should be Low cue ball squirt.

It's also true that the shaft "deflects" more so the cue ball will squirt less. But, the question is, how much?

Keep in mind that all the shaft deflection and cue ball squirt must occur during the tip to ball contact. Given that the contact time is extremely short, the question really is, "how much can the shaft deflect during that time"? And then, you have to compare both LD and regular shafts so you can measure the time difference between them.

It's pretty easy to see that we're talking about a tiny difference.

As strange as it may seem, it really has nothing to do with actual stiffness because there just isn't enough time for the stiffness to make enough of a difference.

It's really all about mass.

Hi joey

Well if they say so

You know I got burned pretty bad on some LD shafts, and cues.
Honestly speaking I haven't ever been so dis appointed in a cue like the cues I got from Meucci.

It was all bad, The cues , the materials. and the warranty policy matched the cues.........:
So honestly I think some of these cues and LD shafts are poor enough constructed that it would be against forum rules for me to really be upfront and not reserved expressing my full meucci black dot cue experience.
 
I play with a very stiff cue that squirts the cue ball very little (LD).

The term "low deflection" is probably the most infamous word in pooldom You would be more likely to be able to make all 9 balls on a 9 ball break before you could have that term changed.

On cue/shaft construction, I have a policy in evaluating a cue/shaft and that is, I let the performance of the cue/shaft tell me just how good of a cue/shaft it really is. Glue is used in practically every cue that was ever made and the glue keeps getting better. :smile:

Well, here's something to consider.

It's true that the term LD isn't really correct. It should be Low cue ball squirt.
I also prefer "low squirt" (LS) or "low cue ball deflection" (LCBD); although "low deflection" (LD) is so established, it might be difficult to change. Although, since you are part of the industry, doing your part can certainly help (e.g., by using LS instead of LD in all of your marketing and labeling).

It's also true that the shaft "deflects" more so the cue ball will squirt less. But, the question is, how much?

Keep in mind that all the shaft deflection and cue ball squirt must occur during the tip to ball contact. Given that the contact time is extremely short, the question really is, "how much can the shaft deflect during that time"? And then, you have to compare both LD and regular shafts so you can measure the time difference between them.

Well stated Royce. It is true that the shaft doesn't deflect very much at all during tip contact. The shaft deflection and vibration occurs after the CB is already gone (due to the sideways momentum imparted to the endmass). Shaft stiffness has an affect on "endmass," but it is endmass (and not stiffness) that causes squirt. If people want explanations, illustrations, and video demonstrations related to these effects, see:

Do you want the list of folks that were screwed by "custom cue" makers. do you ?
 
Cues

Do you want the list of folks that were screwed by "custom cue" makers. do you ?

I don't buy any cue that I think is going to fall apart..........................

But I sure got 3 of them from Meucci cues and they all had LD shafts on them.
If they would of replaced them like their warranty policy said, then there would be no reason me to post pictures of there cues that have failed .

The topic of this thread is Low Deflection shafts.
The picture above is a low deflection shaft.

The shaft performance was poor if not piss poor.

The picture pretty much says it all. the shaft is delaminating for one reason or another.

Problem is I have pictures of 3 or 4 Meucci cues with the same problem and different owners .


If a custom cue maker has made a LD shaft for you, then this thread is about LD shafts and you should feel free express your experience.

If you want to make a list go for it,
