Cynergy shaft issues

One day I was having a new tip put on and he grabbed the 12.5 mm collet and when he slid it on the shaft about 3" from the ferule it actually rattled and wouldn't hold tight. :oops:
If that wasn't bad enough, he was using a Porper lathe where a fair amount of the joint end of the shaft sticks out of the head and it was bouncing so bad he had to ask me to loosely hold onto it to keep it from oscillating too much because of chatter on the other end
Great story. Makes me feel good for my putting tips on by hand --- its not that dangerous or scary.
 
.09 difference isn't significant at all. It's the thickness of a hair or less. So each side of the shaft is around 1/2 a human hair less. It's absolutely insane to even think about something like that being a defect or effecting your shot in any way. Pool is 90% mental and this is definitely in the 90%.
Of course it is a defect……..taper should always change gradually, progressively but consistently
too, not back and forth or in this case, up & down. Taper should not fluctuate like the OP described
even with a wood shaft but especially with a CF shaft. Building a wood shaft involves removing wood
whereas manufacturing CF shafts involves more precise technology. This shouldn’t have happened, IMO.

p.s. j2pac’s post makes a good point.

Believe it or not, CF shaft tubes are subject to manufacturing defects. The quality protocols of the various tube manufacturers are not equal. They should be more consistent than wood, but the chance of variance is there...Having said that, I would encourage the OP to utilize the warranty.
 
Thanks for clarifying that…..it just seems that with the precision machinery, casting and final finish, sanding, etc. ,
I’d expect, or more candidly stated, presumed it would be more precise. But I’ve long admitted that I know zilch
about CF pool cue shafts other than they popular, low deflection, durable, impervious to warping & that’s about it.

Warp is a relative term. These tubes can be "out of round" enough to cause some issues. The trick is for the Cue-Maker/Production cue company to select precision blanks for the end user. Placing a warranty on a CF shaft is relatively easy for the Production company to do, because it takes less time to finish a shaft for replacement purposes. With CF, you're basically skipping the seasoning process that is required to produce a quality wood shaft.
 
it's not uncommon, the inconsistency of carbon fiber shafts... I have seen shafts with inconsistent specs, from Cuetec, JFlowers, Peri, How,...

many of them are not round tubes, deviates at many points along the shaft, you can feel it when rolling the shaft at different points against your fingers, you can feel it may not be perfectly round

I've hit with a bunch and owned few and not one had any defects you could feel against your fingers. I'll go out on a limb and say that the 'problem' the op has is far more common than what many may think. I personally don't think such small discrepancies are an issue in using the shaft.

have you tried rolling the shaft with 2 finger pressing at the shaft wall? different points, you may feel that.

I noticed that with cuetec cynergy, both break and play shafts, peri, jflowers smo... but not with revo's

I agree the minor thing the op noticed, and what I noticed, may not affect playability, but they are premium priced.

not that anal dude. i've hit a bunch of cf shafts and have never felt anything like what op or you are describing. i'm betting that if everyone on az pulled out every shaft they own they are going to run across 'micro flaws' like this, wood or carbon. i don't sweat minutia like this.
