I can spine that club but i can't figure out which way to point the NBP. Do you point it with the club face or facing the target. Some say toward the target and some say away from the target. Which is better and why. I'm using a LD3 long drive shaft with swing speed of 130 to 140. One driver that I have has the NBP facing up which I hit very good but was wondering if I change the spine would it help. Any help would be great. Thanks Daddy2

Re: Correct way to Spine
A couple thoughts (as this has come up recently on other boards):
SPINE (S1) to 12 o'clock. Imagine swinging a yardstick. Swing flat side to target (this is S1 @ 12). Now swing swing it edge to target (this is S1 @ 3 or 9).
Long before spine, I prefer to set FLO to target.

Re: Correct way to Spine
LP - I was going through Tuttelman's site (shaftlab stuff) and the discussion seem to indicate that the shaft bends more on the 1:30-to-7:30 line over the course of the swing (especially at impact). If the spine (NBP) is aligned this way then the shaft is bending against the weakest axis - would this not lead to greater consistency?
I posed this question to Dave - his response - more analysis is required - perfect engineer.
Also posed this to Kauffman - his response - buy shafts with little to no spine - very practical.
Something for you to think about - or test if you feel inclined and have a very large spine shaft in your discard pile (and the snow ever melts).

I still find the FLO plane and orient it accordingly, as I believe this trumps the spine. That said, depending on where I find FLO, I'll place the spine to either 12 or 3 (away from target).

Re: Correct way to Spine
I have always tested for flo with the customers clubhead on the intended shaft and then glued it. To me it's the ONLY way you'll actually achieve true FLO in the end product. Not one customer ever complained, and I keep in touch with them.

Re: Correct way to Spine
I'm confused - this demo from YouTube:
http://uk.youtube.com/watch?v=DqlRIiz_OLE
Says the spine is on top of the shaft when using a spine finder, but JB's demo says it's the NBP and the spine is 180 degs to this (ie. underneath the shaft when spining).
Who is right and wrong?

Re: Correct way to Spine
OMG That is NOT the correct way to mark the spine!!!!!!
What the video shows is how the spine deflects the shaft. He has marked a point IN BETWEEN the spines and is about to screw his club up royally!!. Think of it as a yardstick, is it easier and more stable to bend a yardstick along the flat side or along it's edge? The spine is the edge of the yardstick and keeps the yardstick stable as it is bent along it's flat side.
The proper way to find and mark the hardest spine is to turn the shaft until you find the point where the shaft resists turning in the bearing. Mark THIS point AND THEN- AND THIS IS THE MOST IMPORTANT PART- dry fit the shaft firmly into the head that will be used so that the spine you found is between the "12 o'clock (top of the shaft) and 1 o'clock" positions (as viewed looking down the shaft toward the head). Now clamp the butt of the shaft in a vise or whatever you use (a grip station vise works well) so that the clubhead is either facing you or facing away from you (such as facing the target line) and is free to move back and forth (or around in a circle). The spine will be aligned when the shaft is "twanged" (yes, that's the term we use!) (pull the shaft about two inches straight back toward you and release it) and the head moves straight back and forth CONSISTENTLY (it doesn't move in an oval or circle AT ALL). This is called Flat Line Oscillation or FLO and can be achieved with the spine at the top of the shaft or the bottom, either way it works the same. Reposition the shaft in the head by turning it in small (approx. 1 degree increments or smaller) until you get FLO. Hope this helps!

Re: Correct way to Spine
So if the target is 9 o'clock, you are saying that the spine should between 12 and 1 o'clock?
What is the point of spining if FLO techniques are able to find the FLO? If a shaft FLOs what use is knowing where the spine is, or are you supposed to balance between the two?

Re: Correct way to Spine
If there's a large spine, you still orient in as close to 12 o'clock as FLO will allow.
IMO, FLO trumps spine every time.

Does this mean your brand new off the shelf £200 - £1000 golf club drivers and sets may not be spined correctly?
Yes. The major companies won't pay the extra money to have their employees go through the process. The major problem for them is that they would have to pass the cost to you and admit that they haven't been doing all they could to provide the best product to you.

Finding the hardest spine first is the starting point. From there you could put it at 12 o'clock and start checking for FLO but I've found it quicker by starting with the spine pointing closer to the COG of the head.
I agree that FLO trumps leaving the spine at 12 o'clock (which is what the SST PUREing process has you do).

Re: Correct way to Spine
Tweaky / VaultTec - I'm just getting up to speed on spining and flo-ing so have been reading a lot of previous posts. I'm confused by this thread - hope you can help.
VaultTec, in previous posts I've seen it indicated that you should align the dominant spine either at the target or away from target (9 o clock or 3 o clock), but in this thread everyone seems to agree that the spine should be put up to 12 o clock.
I understand you guys place more emphasis on FLO, but it would help if you could clarify this for me.
ps.. I'm not sure of the yardstick analogy applying to something that is round and has only one dominantly strong edge - just an opinion.

Oh man... you mean I need to search and edit a ton of posts?!
At this point FLO goes to target and any significant spine goes to 12 o'clock. I used to manipulate spines to and away from target to help induce or reduce the addition of dynamic loft through impact by allowing more flexing or less by spine orientation (back before I would FLO). Now I like spine at 12 to help promote designed shaft action through impact and to help offset toe droop.
There's been lots of learnin' through the months and years.

Re: Correct way to Spine
VaultTec - thanks, much appreciated. Guessed there had been some changes, and yes it was an earlier post I had read !
I'm installing a Graffaloy Epic x FW and a Comp NT x in my driver. I can't really find any significant wobble when I flo them, although there is (possibly) a couple of points where they vibrate straighter.
Is this common with new shafts - have the manufacturers cracked it with build quality now?
