SHAFT FLEX QUESTION

Ringoblack · 2022-05-02T19:57:11+00:00

I have two drivers that are identical (same shaft length, shaft, grip, head ,flex, weight, SW, etc.) The only difference is that 1) one head is 13* and the...

LogicalOne

I think it’s extremely unlikely (impossible) that the shafts are identical. There are way too many characteristics/variables/tolerances. How different are they is a better question to ask. True weight, balance point, spine, residual bend, cpm’s, consistency of paint, etc….

Same can be applied to the heads, grips to a degree as well. All add up, in my opinion.

Very true. But there needs to a be a considerable difference in the shaft for the average golfer to ever notice a playability issue. The fact remains now that when the 10 degree is hit, there is already a preconceived notion that the eventual shot will be less than acceptable.

My question as it was a bit unclear. Are both heads the same model and same manufacturer? Just different lofts?

Weighting within the heads themselves??
It is easier to pull, than push.

Weights of the heads? Lighter weight can make a shaft feel stiffer? Maybe one shaft has a very heavy spine that needs to be oriented in a different position?

Ringoblack

I think you are right--spine orientation seems to be different between the two shafts. I put a weight (3 lbs) on the two to see what deflection I got. The 10* deflected 7.5 inches wrt a fixed baseline and the 13* deflection was at 8 inches. Plane of deflection was perpendicular to the plane of swing, but I think it still proves something.

It really only proves that you have a 3 pound weight lying around. ☺

Graphite shafts are always sanded. Table rolled shafts (often with a heavier spine) more so than filament wound shafts.

You also might not have used the same clamping pressure as a result of one shaft being thinner in the butt than the other.

Only one way to settle that. Have each club FLO'd. It will show frequency number as well as if one is wildly different when it starts looping all over the place.

Ringoblack What do you mean by "they are within 10"? CPMs?

DonM
It's an angular measurement ( an eyeball guess in this case). Not 10 inches, but 10 degrees.

When you can't find a physical difference in clubs, it comes down to poon.

KCee This is why I wish we had archives of all the old FGI threads. So much poon... all of it gone.

It's hard to find poon meters. Golfworks.com doesn't carry them anymore.

Ringoblack

KCee Guess they ran out when the 10* was assembled. Have to get another bottle. Do you pour it down the shaft or into the head???🙄

KCee

sdandrea1 You should feel a bit of tingle when you hold the club 😱

Ringoblack

SMT Yep. Same Model just different lofts. They are Callaway clones ---Pinemeadow Excel titanium 460. Same shaft, Same grip exactly as assembled by Pinemeadow. The 13* pops off clubhead, the 10* not so much. I can "feel" the difference in them.

You should feel it

Un-confuse me here.....WHO built these 2 drivers, you, or Pinemeadow?

KCee

Ringoblack I believe you have to cover the whole club, but I'm unsure of the rest of the ritual.....I can never remember anything after the peyote kicks in.

SMT

Ringoblack and shafts are installed almost identical (They are w/i 10) into the heads.

Thanks for the clarification. Your opening post said this (quote)

How do you know?
It really seems like you have a shaft that is not at all aligned in the head the same.

Ringoblack

SMT That's what I am thinking. Guess I need to get the 10* FLO'd. Don't want to touch the 13* or the poon will escape.😀 And I'm fresh out.

Ringoblack

KCee ....I can never remember anything after the peyote kicks in.

So, I guess you are saying peyote and poon go together?😉

SMT

Ringoblack Even if it isn't a perfect FLO, you can and should have the 10 degree re shafted to match the 13 degree.

Ringoblack we've all probably loved a shaft in the past that we bought a second one that felt nothing like the original. Could be tolerances, shaft orientation, who knows

Ringoblack

Par4QC Pinemeadow built them.
