Deflection question, explain how a stiffer CF shaft has less deflection.

I just got done shooting an old school cue today with a maple shaft and its one of the best hitting cues.

Deflection could very well be a myth. If anything, a carbon shaft gives me more trouble.
Not a myth. You probably don't understand it, and you compensate for it without even noticing by force of habit.
 
Whatever works for you is the right way to go
I tried an LD wood shaft maybe 10 years ago. I couldn't get the hit on that 90 plus degree table length frozen to the short rail cut. That was the end of that. With standard shafts 4/5 ball give or take and it was dead. BHE plain works.

It’s a matter of studying the shaft and practicing
 
I suppose but got no reason to switch. Maybe one. I reason you can spin many shots with more force with CF but with no pool rooms here, moot.
One shot is not a reason to go this or that way.
Standard shaft requires guesswork when applying spin. LD shaft requires less guesswork so over a long period of time, you’ll miss less shots with side spin.
This why, a few shots or a few racks won’t help you (or anyone else) to understand LD shaft and its benefits.
Low deflection is a buzz word and there is no standard or minimum standardized testing deflection that is needed to define a shaft as low deflection.
For me the reference shaft is Predator 314.
Anything that deflects more, you might as well go with standard shaft as the guesswork is about the same.
 
Not for you maybe. I had no reason to change anyway. I was handed the complete custom by a local cue maker. Nice cue, not enough deflection.
Not trying to wrap my head around LD. What I do works fine including the judgement involved.
 
So why is the predator 314 shaft lower deflection than other wood shafts of similar diameter?
because the front end is hollowed out and replaced with lighter material. also a light ferrule is used. their Vantage shaft is larger and less defl. than the 314. the larger diameter lets them remove more material thus a bigger mass reduction. the Vantage is my favorite wood Pred. shaft.

But it’s more about what remains than what’s removed, and since the tenon “walls” are (presumably) the same thickness, their wider diameter adds mass.

Well, I read Dr. Daves stuff on LD and lets agree that end mass is the biggest factor in deflection. If you reduce end mass which allows the last 5 to 8" of the shaft to bend more out of the way of the shot line upon ball contact, you reduce deflection.

If however you compare a wood and CF shaft that are identical, same weight, especially the last 8" to the tip, same size/weight ferrule, etc, the CF shaft would create more deflection as it is stiffer than wood and will not bend off the shot line as much as the wood shaft.

Dr. Dave does mention that CF is stiffer than wood and because of that, does impart more deflection than a wood shaft that would be identical in specs, (which I think was my original question).

I've been using Predator pre-cat, and cat shafts, and Mez WX700 wood shafts for many years and the only difference is the Pred shafts seem to hit a little softer than the WX700's. If there is any difference in deflection I can't tell it. I suspect any deflection is less pronounced on the 3.5x7 tables I mostly play on compared to a 4.5x9 table.
I don't wear a glove or have sweaty hands so CF does not offer me anything in that regard. I actually like just a tiny bit of friction a wood shaft gives me that the CF does not. It's great that we have many cue/shaft options to choose from.

Thanks for all the replies.
 
There are CF shafts out there that flex more, like the SMO and Cuetec.
It is really comes down to the taper that affects the flexibility that you feel in your hand.
The front end mass is what makes the shaft to deflect more or less. I believe that the flexibility at the end of the shaft is something that tou can’t feel and can’t see without a slow motion video.

I have an InFuze keilwood shaft that is stiffer than my SMO and both perform about the same when it comes to deflection. I was quite surprised as the InFuze is quite heavy.
The new Becue Prime II has the best flex to stiffness of any shaft I have ever owned, wood or CF, a CF shaft does not automatically mean lower deflection, some people think filling a CF tube with some foam and "wala" I have a low deflection shaft now, it doesn't work that way, Becue orients the fibers at different angles in different parts of the shaft and have a technology called the "aurora" front end technology among other things that go into making not only the shafts but the entire CF cue, the best part for me is the consistency of the products, when you find the shaft you like your spare shaft plays just like your main shaft, no more "favorite shaft syndrome "
