So based on your understanding, where should a shaft bend?
Hi Kim,
In the bridge area.
The exact point is subjective and will determine the exact harmonic frequency of a shaft relative to a pool ball and CM's specific design configuration, ie " The Hit ".
There is a reason that a 13 mm or slightly larger maple shaft is optimum for a repeatable measured stroke IMO. One can question this statement but I would respectfully disagree.
Billiard balls are larger and heavier for example and they require a stronger climb and flex point with an all together different overall shaft design.
Ray Schuler spent more of his time (years) and energy studying and experimenting with this exact subject more than most people in our trade understand.
I lived one mile from his shop and was lucky enough to be mentored by Ray's best friend and pantograph artist Stew Mortsen. Today Stew is 95 years young, is living and driving independantly and is still sharp as a tac. God has blessed him with great genes.

No such thing as optimal ( btw, the word is optimal, not optimum ) diameter for a "repeatable measured" stroke .
Years ago, they took a survey of professional pool players' shafts, they averaged less than 13 mm.
3-Cushion players do not play with 13 mm tips for sure .
Most play with tips a lot smaller than that.
Ray Schuler was a great cue maker but his shaft taper was not a popular choice for pool players . And that continues today. Z3 shafts might be the exception among these "performance" shafts .
The most popular taper these days is the " pro-taper " . Meaning the taper is about 1.25 mm or less to the middle of the shaft .
Anything about 2mm or more of taper to the middle is considered "stiff" taper these days. And it's not the popular choice.
And I would venture to say, most players these days prefer compound linear tapers on their shafts. 3 to 5 linear angles . In cue making , you are really just concerned about the 3 angles. The other two are just there to meet where the stroking area ends and where the joint taper matches closely the forearm's.
Learned that eons ago from writing taper codes manually.
