Reverse tenon ferrule on a wood shaft

While watching the latest Studiotronics cue making video I saw that he puts the tenon on the ferrule and screws it into the shaft. I know the carbon fiber shafts have a similar design, but I hadn't heard of this on a wooden shaft. Is this technique common or is he pioneering his or a new idea? Does it have any benefit for a wood shaft?

I think read somewhere about it ... That is why the reverse tenon isn't common.. weaker... Sure the tenon is stronger but the part holding the tenon is now weakened

That would increase deflection as the ferrule material is heavier than wood, right?

The ferrule materials I've seen have densities much greater than wood. The small diameter tenon has less material than what is surrounding it, unless the outer material is thin. If the tenon is 0.7 of the overall diameter of the tip, there will be equal amounts of material.

The "ferrule" itself (not the tenon) would be a solid piece of plastic vs a plastic with a hole in it.

I built my break shaft like that couple years ago, still going strong but I only did that because I was changing a Ferrell on (if I remember right a McDermott shaft) that was built the same way so wanted to see the difference

Poor idea imo....hard to find a material equal to or less than the weight of just maple. True this similar style is used on CF shafts but think about it and why it used that way. It is also used on CF shafts in a much different fashion.
People in the "low deflection" community group rant and rave about shafts with no ferrule for a reason. They are low deflection.
The solution for people that can not or do not like to play with a shaft that has no ferrule is to install a thin wall, thru ferrule and figure out how strengthen the end that the tip is installed on for longevity.
All other ideas are heresy! ;)

I think this type of setup with a short visible portion may have some merit, especially if your coring the shaft. Depending on the type of material you use you can probably core that a tad too.

There's cue maker (Bob Dzuricky I think) that has a chart of materials and their density. I can't find it anymore. It would be interesting to see a comparison between this set up with only 1/4 inch showing and a traditional setup with a larger ferrule. I seem to remember there were a few of the materials that scored pretty well.

Disclaimer, I work on my own cues, I'm not a cue maker by any means.

Hey it’s me, the talkative handsome guy in the videos

Thanks for all the feedback. I tested the ferrule implementation shown in this video fairly rigorously and never managed a cracked tenon. It felt strong, solid. Love the feel. Im pretty picky about shaft wood so maybe that comes into play. Dunno. I also tested juma 1/8, 1/4, 1/2. The amount of squirt difference was imperceptible (to me). I also tried LBM, aegis, elforyn, q4, resin ivory. A gajillion tapers.

(I actually care quite alot about what I’m doing in my small excessively hot Texas shop. Maybe I’m not conveying that on YouTube effectively)

Perhaps my tests are inadequate or done incorrectly. Maybe. Probably. I’ll be the first in line to say I am likely making tons of mistakes. Who knows. Self taught. Doing the best I can. Hedonistic 20s but the ole brain is chugging along. Since that video I’ve found a better way to do ferrules anyway. Not because of any perceived deficit, but just because I like to tinker and test new things. Way more fun this way. I don’t like to ask how to do things on forums, I like to figure it out on my own. And yes I’ve likely suffered greatly because of this. But it also gives me a deep understanding of cues in a really quick and efficient way. And it makes for better YouTube content.

It’s still early days for me. It’s all evergreen, living, changing. Every step of the process. Trying to improve the best I can while soaking it all in. I mention (often) that I consider myself a beginner. That’s not hyperbole. And if you ask me in ten years I’ll likely say the same thing. Lots to learn.

I don’t read/visit azbilliards, email is best if you ever wanna talk shop or have a question or whatever- studiotronicsYT at gmail.
