Was talking to an old Timer who SWEARS Shaft have a SWEET SPOT, (being the Point the have the least deflection).

So he marks his Shafts with a Very Think black Line of like India Ink, or Sharpie. So when he hits a Cue Ball the Black Line in Running Parallel Line to the Ceiling.

Apparently this guy is some Retired Engineer, who do some study on Wood, Cue Shafts and has a Theory that works for him.

I noticed the Black Line Running Down his Shaft, ask what the Line was, that and got a long Lecture.

Never did figure out how he found his Shaft’s Sweet Spot as I did not understand much of what the Guy Said. Had to do with Grain Structure & Grain Pattern?

Anyone ever hear of such a thing. :confused:
 
Yup, lot's of old timers used to put a mark on the shaft so that it was always in the same direction when they hit the ball. Long before the Black Dot, Red Dot, Predator and any other special shafts.

Did you ever notice the two lines of fine circles that run the length of the shaft? Put your mark directly between these two lines. It could actually be anywhere, the important thing is that it is always oriented upward. You are just giving yourself more predictable shaft deflection, which in theory gives more predictable cueball action.

Well I quess the old boy was right. He could shoot well, and will never see 75 years young again. ;)
 
I think the wood bends differently along the growth lines and across the growth lines. That's why this old fellow wanted to have the shaft in the same position on every shot, no surprises when applying spin on the cueball.

If he truly is a retired engineer, then he's talking about shaft deflection which has very little if anything to do with cueball deflection.

I've read lots about the the fact that shafts all have a spine, or a tendancy to bend easier in one direction than another, but I've never been totally convinced that marking (lines, dots) the spine and being able to use it to increase consistency.
Here's why: Say you have your shaft marked on the side where the shaft flexes the most. So when you're using something like 1 oclock top right on the cue ball, then your mark on your shaft should be at the same 1 oclock position. Same goes for using 11 oclock top left, then your mark needs to be at 11 oclock? In other words the mark on the shaft, in my opinion would always need to be in a position that corresponds exactly to the position of the cue tip in relation to the center of the cue ball? Facing down for draw, facing up for follow, right for right ect????? If the mark on the shaft is facing up on both follow and draw shots, then for follow (if the mark indicates the flexable side) your shaft will tend to give or deflect easily, whearas if trying to draw with the same mark on top, the shaft won't be less forgiving because the flex side is not facing down?
This all seems like way too much for a guy to be thinking about while going through a pre shot routine. Besides that, most players that have been playing for years tend to rotate their cues in their hands as they're taking their warm up strokes, so it seems to me, that if you're over concerned with "keeping that dot/mark on top" while doing your warm up strokes, it could easily result in a tight grip.
I agree that woods all have a direction in which they tend to flex easier, but to try to identify that point and to actually use it to ones advantage seems like the addition of allot of unnecessary thinking to a process that should be more felt than thought about.

Pool Shafts

It's the same premise as lining up the wood grain in a baseball bat so that the grain meets the ball. That keeps the bat from bending (deflecting) too much and therefore breaking. Whenever you see a player break a bat by hitting the ball it will almost always be because he had the bat turned wrong.
 
Didn't Meucci do this with their Red Dot shafts? I think Meucci said that the shaft will deflect less if you have the red dot facing up.
