Will someone caliper a Carbon Fiber Revo Shaft?

Will someone please measure a Revo shaft diameter? Or any shaft that is carbon fiber. I want to know which companies have high standards and which is a gamble. I just ordered a Meucci Carbon Pro at 12.25 and they sent me a 12.00mm. Waiting to hear back from Budget Billiards. If anyone has calipers, go measure your CF Shaft at the ferrule and report back.
1. get calipers
2. measure shaft at the ferrule.
3 post advertised measurement vs. actual measurement.
consumers need to know this when they're dropping that much $ on equipment.
Let's make a list of actual diameters vs. advertised diameters. I think this will help serious players choose the right gear and know more about each company. For me, the difference when I'm down on the cue ball between 12.00 and 12.25 is a lot. I've also heard that it's harder to be more accurate with the CF diameters.
I've had another user measure 3 Revo 11.8s. He said they all actually measured at 12.00mm
 
You seem overly concerned with the tip diameter. Just pick something and play with it.

lot of CF shafts is that the seller does NOT make the tubes. I know Cuetec and Revo make their own but most do not so they are at the mercy of their suppliers. A little +/- deviation is ok imo but big differences are not. What those allowable variations will vary from player to player. For me personally a .20-.25mm difference would really not bother me. I'd get used to it in one session of play. For me the tipping point is +/- .5mm. As for accurarcy, ANY small diameter shaft(wood or CF) is more punishing to stroke errors.

I agree with the above comments. Personally, I find it nearly impossible to discern shaft diameter variation < .4 mm, and I’m able to get used to anything in a few racks. I’m more sensitive to overall taper profile and weight, and resulting stiffness/feel than any absolute measurement. But I am a nerdy engineer and have measured my shafts, so in case it helps you out, here’s a pic of some of my data. Left to right the first 3 are Cynergy CF’s all 29”, #4 is a gen2 Meucci CF pro 30” (gen2), all CFs are spec’ed to be 12.5 mm. #5, 6, & 7 are my favorite 29” maple shafts, Dzuricky, Bill McDaniels, and John Davis respectively.

I used to have same data on some other CF shafts I tried (Meucci gen1, Revo, Jacoby) but didn’t keep it.

A few observations:
- My 3 Cynergy CF shafts are all sold as 12.5 mm, but are 12.6-12.8 mm. I can’t tell the difference when playing them, even test hitting right after each other. As a whole, they are really more like 12.75 mm.
- If you really want to get a feel for consistency and variation, I would suggest measuring the shafts through their entire taper profile. I measure at the ferrule seam and then at 3”, 6”, 9”, 12”, 15” from tip and take an avg of the first 12”, as most pro tapers get fatter after 12” and most folks stroke won’t use much beyond that in actual play, at least I don’t.
- Measuring only at the ferrule can be misleading. See table below, all 4 of my current CF shafts with advertised 15” pro taper actually measure slightly fatter right at the ferrule then are slightly narrower and consistent through the first 12-15”. No idea why this is. None of my wood shafts are this way. Maybe to do with how CF ferrules are tenon less and fit directly into the shaft tube, with threads/glue causing minor bulge? (Wildly speculative guess, I’m no cue maker…)
- its pretty easy to introduce measurement errors when looking for .25 mm, just varying the amount of finger pressure on the micrometer calipers can bounce things around.

For what its worth, here you go:

Cuetec ferrule has a short tenon that fits in the shaft. Don't know about how others do it.

Correct. I just replaced the ferrule on one of mine. But that is not actually the definition of a tenon, and its different from how ferrules are installed on the vast majority of
wood shafts. None of which is a problem. I was simply hypothesizing why CF shafts seem to measure slightly fatter than their diameter spec right at the ferrule seam, where that doesn’t seem to be the case tor maple shafts. At least not in the 10’s I have measured. This guy seems pretty anal retentive (like me), so I thought he might be interested in that level of detail.

Its all tiny stuff & I think we are both advising the dude to not sweat it & go play.

I just measured my two 12.4 Revo's. My original black ferrule measures 12.39. my new white ferrule12.42 I did use a cheap plastic caliper from Harbor Freight.
 
Revo advertised 12.9, actual, 12.91.

To put it into perspective, 0.1 mm is the approximate thickness of a single sheet of standard copy paper.

Your Meucci CF is advertised at 12.5 but measures 13.1.
.6mm is not acceptable fluctuation for a 12.5; they clearly sent you a 13mm shaft...maybe 12.75mm.
My concern is if they are going to be advertising CF shafts with .35mm difference i.e. 11.9 & 12.25 then .6 in fluctuation makes no sense. Not even .35 in fluctuation. If I've ordered 12.25mm I think 12.15-.12.35 is acceptable. Outside that range they have a quality control problem. They're cue makers; they should be more aware of this variation than the consumer...not the other way around. I love the feel of Meucci but they will get left behind if they don't evolve to modern day standards and quality control the way predator does.

See Budget Billiards post for update on my CF shaft return.

I agree. That 13mm (“12.5”) Meucci shaft was their 4th attempt - at least this one has a proper 3/8-10 modified thread that fit my cue, rolls straight and the custom ring sizes I ordered. Good luck with the Julia/Darren gymnastics, hope you fare better than I did. I ended up cutting my losses & aborted. Do note my Cynergy’s measure larger than advertised as well, but I’m apparently not as sensitive to it as you. Would be interesting to see how Revo’s & others measure out. There seems to be no official “standard” for how to measure shaft diameter… Most folks talk values at the tip/ferrule, but that can be a bit misleading, see data above…
