I've had a couple customers ask about replacement of the ferrule on a Cuetec Cynergy due to the ferrule itself mushrooming. I have yet to take on a CF or fiberglass repairs. Suggestions???

Not warranty
Cuetec offers an authorized repair service....
www.cuetec.com
It literally says the following on the Cuetec website:
Replacing the ferrule on your Cuetec Cynergy Shaft.
While unlikely, should the ferrule on the Cuetec Cynergy shaft ever need to be replaced, it must be done by an authorized Cuetec Cynergy repair center. This is required due to the complex nature of the bonding agents used and to ensure that no damage is done to the shaft’s carbon fiber filaments. To locate an authorized repair center near you, contact customerservice@cuetec.com.

No different to any other ferrule work. The ferrule goes .500" into the shaft. I use Elforyn as it's fairly similar in weight and colour. I have probably done 20-25 of these allready as the original ferrule is junk.
As with any CF shaft work, accuracy is very imortant, so make sure your workpiece is as concentric as possible.

Thank you for the response and advice. Yes, they are junk. I've seen several that are mushroomed. My customers are flowing in with these. Are the Cynergy ferrules T type ?
Yes I guess you can call them T shaped.
Whatever material they use, it melts and distorts very easily.
I have had no complaints after switching to Elforyn. I use 3M DP460 epoxy on all things carbonfiber, as it's designed for carbonfiber and is impact proof.

I purchased replacement T-ferrules, however from what I'm gathering I should toss them... Thank you again for the advice.
I replaced my Cuetec Cynergy ferrule with Tomahawk material. Cut the new ferrule from a Tomahawk rod and shaped it like a “T”. I then installed it like I would a new tenon for a wood shaft. Used epoxy to bond it to the shaft. This really reduced the ”tink” sound. An UltraSkin soft tip really helped too. I too think Cuetec should use a better ferrule.

Thank you Tom
Are those Cynergy replacement T-ferrules?
Have you tossed them?
Where did you get them?
Could there be some benefit from the Cynergy ferrule over that of the Elforyn or Tomahawk material?
Anyone tried replacing Cynergy's ferrule with Rhino's $5 ferrule?
Rhino's ferrule comes in nine sizes for the nine widths of Rhino shafts: 10.5mm, 11.8, 12.2, 12.4, 12.5, 12.6, 12.7, 12.8, and 12.9.
Their figure below must have a mistake claiming the width of the plug portion of the ferrule varies from 10.5 to 12.9mm. That would mean Rhino's smallest ferrule would be too big to fit inside Rhino's smallest 10.5mm shaft (a hollow rod) and, likewise, the largest 12.9mm ferrule would be too big to fit inside its largest 12.9mm shaft.

Not likely, since matching the exact diameter would be unlikely. Tolerance should be under .001"
It's also unlikely they would disclose what their material is. It's probably something proprietary.
______Tolerance of 0.001 inch = 0.025mm
Just a note that their figure of a 10mm-length ferrule has about 7mm of that 10mm inside the shaft and 3mm sitting on top of shaft. That is a narrow ferrule width. That seems about right since the tip in figure below is about double the width of the ferrule width. The tip could be a taller width tip of 6mm.
I like .4" inside the shaft. Cap height will usually match what was there. If I'm making the shaft the cap height depends on the material used, the smaller the better for weight, but tall enough not to fail. I also like to bore some of the material out at the base for further weight reduction.

It appears the Rhino carbon fiber shaft (presuming the Rhino ferrule spare part is used in Rhino new shafts) has a ferrule plug sitting 0.275" (7mm) inside shaft instead of Sheldon's preferred 0.4 inche depth (10mm) --- 30% less than Sheldon's preferred plug depth.
It takes 10 minuets max to machine a ferrule..
