Cynergy shaft issues

I recently bought a new Cuetec Cynergy 12.5 shaft. I have noticed a variance in shaft diameter at the tip end. It is supposed to have a 15.5 inch pro-taper. It starts out as 12.5mm at the tip. As I move down the shaft towards the joint the diameter dips down to 12.41 then up again to 12.5. I was wondering if anyone else had this issue. It feels weird. I am tempted to sand it all to match. I have may have waited too long to report it as a warranty issue.
 

Cuetec Warranty

Cuetec Warranty. The cue must be registered on our website within 60 days of purchase to activate the warranty. Limited lifetime warranty applies only to the original purchaser of the cue and is not transferable. The cue must be purchased through an authorized Cuetec dealer.

Don’t pay attention to opinions or advice telling you to indulge, ingnore, tolerate, etc. any irregularity in your pool cue
that you find to be distracting if you can do something about it. Send the shaft back and ask them to repair or replace
the shaft since this is not something you caused to happen. Of course, call ahead since pre-authorized returns can
require special handling or include specific reference in your return shipping label. You have the evidence because you already measured the shaft. Do it once again and but take photos of the micrometer reading proving the variance in diameter. You can attach that to any email communication you have with Cuetec. Shaft diameter consistency should never be a problem with any CF shaft unlike wood shafts that can be physically and easily changed. Cuetec should replace the shaft.

It's out of warranty. Consider yourself lucky if they answer the email

.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%.

Yep. I cannot account for the feeling I get from it. It. could be decades of playing with shafts where the taper increases a few inches from the tip. It just feels like it gets smaller moving away from the tip even though measurement, as accurate as I can make it "feels" smaller than it is. The point where it feels smaller is 12.50mm. It is just weird. It just occurred to me that the thing may not be perfectly round.

wait until they start to check their wooden shafts after the sand them all the time...

BTW. the measurements could be wrong....

I'm not saying your measurement isn't right, but when you're getting down to 90 microns it is in the territory where tool calibration and technique really start to get important. Squeeze a bit tighter or be a bit off perpendicular to the axis and it all throws in error. Good quality calipers are usually only accurate to 0.02mm, so this means your ferrule measurement could in reality be 12.48 and the small place may be 12.43, even if your technique was perfect. So you're into the range of 50 microns.

A micrometer would be more accurate, but again it takes a good technique to use. But the caliper is accurate enough to tell me that the measurement is not something that will cause an issue.

I highly doubt anyone is accurate enough by feel alone to tell a diameter is 90 microns smaller. I'm going to leave this topic alone for now but seriously this is well within normal tolerances for a pool cue shaft. I don't know what you're experiencing or think you're experiencing but this is beyond the pale to be this concerned with 0.09mm on a shaft.

Zero out your calipers and open them to display 0.09mm. It's minuscule. Now try 0.05mm, this could be the measurement figuring in the tool's resolution/accuracy. It's honestly nothing to be concerned with. Manufactured products all have tolerances. Unless it's literally aerospace or an industry where human life is on the line 0.09mm is a huge ask for any industry.
