Somebody asked about the one pocket break recently, which got me tinkering with VP4 (ruh roh). Hope this is helpful. pj chgo Typical one pocket break - good result

Oh, I see what you mean now - shoulda known. Thanks. pj chgo

I'm guessing by "torque" you mean the force of the cue's impact? Sure, different cues deliver slightly different amounts of force for the same stroke, due to weight (not deflection). The difference is compensated with slightly different stroke force. pj chgo

Right. Deflection isn't a factor. pj chgo

That was the question, alright - and the answer I expected. Thanks. And does that mean the CF shaft will squirt more than an equal-mass maple shaft (because more of the shaft is "involved" as end mass)? pj chgo

I've never seen it come into play - but I assume it must or they wouldn't do it so much... pj chgo

Yeah, bored enough to complain about somebody else's innocent, pool-related interest is plenty. Maybe try smoking a doob before logging on...? pj chgo

Deflection is important for aiming - not for swerve/masse. You're entitled to your beliefs, but I don't think the two have anything to do with each other. Deflection only affects the immediate initial direction of the CB, which is more accurately controlled by simply aiming. pj chgo

For the weight, as Gustav said. Large diameter tips are just what comes with that. pj chgo

A little greater mass = a little less acceleration. OK, that's a small possible advantage (if your stroke is sensitive to it). So how does more deflection help? pj chgo

So, slightly less speed (like any shot with a heavier cue) and slightly different aim. Doesn’t sound like enough of a difference to make the shot noticeably “easier”. And I’ve jumped many times with only a shaft - seems easier, not harder (that’s why we used to do it) - didn’t notice it...

Now you’re deflecting… You’re saying the extra deflection itself is the “work” that’s needed? How does greater deflection help with masse? pj chgo

What “work” does high deflection do for swerve/masse? What extra “effort” is needed without it? pj chgo

It occurs to me that the transverse wave speed (?), which I believe determines the amount of a shaft’s length that counts as end mass, might be significantly different in CF vs. maple. Anybody got an idea? Dave? Bob? Mike? Fred? Ron? Bueller? pj <- infocoholic chgo

I'm thinking the "sections" are the overlapped edges, "cut" at the contact point between them? (y) pj chgo

There once was a product like that - a longish triangular mirror that sat under the rail. Only for practice, of course... pj chgo

For reference, here's a diagram of two 12mm shafts, CF and solid maple, showing how thick the CF walls need to be in order for the shafts to have equal mass (assumes CF's density is 2.5 times maple's). Presumably, these would produce equal deflection. If the maple shaft was hollow at the tip...

Everyone? pj chgo

The poolmudgeons can’t seem to tell when they’re playing pool vs. talking on the internet. pj chgo
