Are any carbon fiber shafts low deflection?

[Bob Jewett]

Do you know if anyone has ever tried to take the concept of a sliding tip to produce an ultra low, or zero deflection shaft, to a working prototype? I can’t remember if that was your idea or someone else’s.

I'm guilty of that idea. I think Meucci had a ferrule with shimmy that sort of did the job. The problem is to put the tip on roller bearings to allow it to move sideways easily but still push the cue ball forward.

Yeah, I took apart a Meucci black dot. The tenon was tapered like a pencil point. And the ferrule was straight walled. (From memory 20 years ago).

A sliding tip would just make the shaft longer or shorter, it won't do anything to the deflection. It would be like moving people around the seats in a car to make it lighter. The only thing that affects how much a shaft deflects is the mass of the shaft, especially in the first several inches. Anything that tries to change things any other way is based on flawed physics and just won't work. You need to change the interaction of the third law of physics between the shaft and the ball.

Edit... I read Bob's reply, I can see that working, instead of using lightness to change the physics, you do a collapsible ferrule that moves out of the way instead of putting the force into the cueball, accomplishing the same thing, like pulling the arm/hand back when catching a ball to absorb some of the impact. Would have loved to have tried that out, especially to see how it affected aiming and hit force.

Cues already have enough trouble staying solid. The design has to remain consistent and functional over a huge range of speeds. The Meucci idea seemed like it could work, but evidently it had a problem.
