Super Low Deflection Cue Idea - Thoughts?

[iusedtoberich]

Here's one possibility. A conically shaped tip endpiece that is pulled into place by a center attached spring or equivalent elastic material that has excellent shape memory.

I had this exact same idea about a year ago. A cone shaped mating surface with a high tension music wire or spring pulling it taught. One day I'll get around to prototyping one (I'm a mechanical engineer with full machine shop capabilites).

Good idea

For those interested, there is a perinent quote and cross-section photograph for the Meucci design at the bottom of the shaft endmass and stiffness resource page.

Here's the photo (originally posted by "Cue Crazy" in an AZB post):

This is the neat thing about ideas... after skimming through this thread, it seems this idea has been around for at least 20 years

"There is no such thing as a new idea" comes to mind But many people over the years can independently come up with the same "new to them" idea

I had also "independently thought of this" many years ago before I knew others had suggested it.

My idea was to have the ferrule/tenon constructed of a bundled set of thin columns (maybe of carbon fiber construction) that could support the large axial impact forces without buckling, but be flexible in the presence of the sideways (transverse) forces involved with cue ball deflection. The columns would need to easily flex and slide against each other during the tip-CB impact.

There are many possible design approaches, but I honestly can't imagine any of them being that useful, nor or they necessarily desirable. The right amount of squirt tuned to your natural bridge length is a good thing. We don't want to reduce it any further. Here are pertinent quotes from the advantages of low squirt (LD) shafts resource page:

- Back-hand and/or front-hand english (BHE and FHE) aim-and-pivot aim compensation methods might be more suited to a player's natural bridge length with a low-squirt shaft.

- With a bridge length well matched to the natural pivot length of a shaft, the effects of any stroke swoop (intentional or unintentional) will be canceled. This can be particularly useful with a break cue, where stroking errors are more likely. For more info, see Diagram 4 in "Squirt - Part IV: BHE, FHE, and pivot-length calibration" (BD, November, 2007).

That's a good idea to achieve anisotropy as I mentioned earlier. Perhaps just 8 spring steel pins around the circumference and another in the center would do the trick.... for testing purposes anyway, might fall apart at break shot speed.

I doubt a super low squirt cue is as useful too Dave, but people love gimmicks and this kind of product would help many to understand the cause of squirt better, and then people like us won't seem so weird. :grin-square:

Colin,

I suspect the kind of people who would like gimmicky stuff like this are probably the type who really don't care how or why something works (or even if it really works at all). They are just hoping for a "silver bullet" solution that will make them play better without putting in the hard work.

You're probably right Dave.

Though if a cue could be made with half the tip deflection as today's LD cues, it might make FHE a more effective means for beginners on more shots.

Honestly, I think it would be difficult to reduce squirt (cue ball deflection) using any of the proposed designs described in this thread (other than the standard endmass reduction techniques); although, it would be still be interesting to see what would happen if people tried.

Catch you later,
