Best Positioning of Spine: 9 or 12 o'clock?

[quote name='Gator5' timestamp='1285543116' post='2715218']
I'm kinda new to this so bear with me. If I put a shaft in my spine finder and mark the spot on top that it keeps coming back to.........

What have I found?

Where should it face when I install it?

I've read a lot of info on this topic but I have not found a clear answer. Thanks for everyone's input and patience.

Assuming that you are talking about a bearing type spinefinder, the top of the shaft is the NBP (neutral bending point). In theory there would be a spine (the stiffest portion of the shaft) 90 degrees away from that point.

A simple and common practice would be to find the NBP in a bearing spinefiner. Then clamp the butt end of the shaft and find the FLO (flat line oscillation) orientation that is closest to the NBP (where the NBP point is at 3:00 or 9:00 assuming that you twang the shaft horizontally).

Then orient the shaft with that FLO line toward the target.

I'm not saying that this is necessarily accepted as correct by all clbu-builders, but this is common.

Thanks that helps. I guess I need to take it 1 step further and twang it. To clarify-I place the spine in the vise at 12:00(NBP at 6:00) and twang it horizontally(3:00 and 9:00)? Then mark the FLO spot nearest the NBP mark? Hope I got it right. Thanks for your help.

i have a pured shaft coming in in a couple days, and i need to know......where do I put the pured mark that they label ??? 9:00, 3:00, 12:00 ????
[/quote]
Every time I've had a club that was SST Pured, the label at 12:00 was between the U and the R on PURE.

I'm assuming this is a typo but Ijust noticed that you said [b]I place the spine in the vise at 12:00(NBP at 6:00) and twang it horizontally(3:00 and 9:00)?[/b]

Placing the spine at 12:00 will put the NPB at 3:00/9:00, not 6:00. I think you meant 'NPB at 3:00.

I bought my diamana driver shaft from a seller in Sweden. He said that he had spined it and said that I should put the logo at 9 o'clock.

Is this true or are all diamana shafts spined the same way (Diamana logo down) though it is an aftermarket shaft?

i had an 83s spined and flo'd by joe kwok and the logo is more toward the 10, 1030 range
[/quote]

Most my Diamana's have the logo at the 4:30 to 5:00 range

When spining, and the club is in the address position, 12:00 is the top of the shaft. You never want the spine there. You want the spine at 3:00, which is directly opposite the face or at 9:00, which is the spine being on the same side as the face. Putting it at 3:00(away from target), supposedly, is better for distance and putting it at 9:00(toward target) is supposedly for accuracy. I usually do spine my shafts to give me a starting point for FLO'ing though. I then put the NBP after FLO'ing at 9:00.

Here's a great article on both from Dave Tutelman: [url="http://www.tutelman.com/golf/shafts/allAboutSpines2.php?ref="]http://www.tutelman....pines2.php?ref=[/url]

I've played around with that and IMO its just splitting hairs; I haven't found that much of a difference between 9:00, 12:00 & 3:00 o'clock. In my mind the most improtant thing is that all of the spines are put into the club heads at the same location; for me that is the 12:00 o'clock position.

I tried to FLO my shafts, but that just seems so hit & miss with a infared lite in a vice; so all I do is spine all of my shafts and make all of my iron heads 6-8 grams apart.

This thread has me completely confused!

Step 1 with JB. Spine Tool: Put shaft in pull down with free bearing and the shaft snaps to[u] [/u]? I thought that was NBP.

Step 2 rotate the shaft 180* until it's stable while still flexing down with the free bearing and you have[u] [/u]? I thought this is the Spine.

Step 3: JB advocated the the first mark established is the NBP and to have that going towards the target, putting the hard side or Spine at 3*?

Now to take this a step farther, everytime I tried to FLO after using the bearing spine finder, I always got NBP ontop at 12 o'clock when using a Mitchel Digiflex horizontal thwang. This basically didn't agree with JB's placement of the NBP. If the NBP is at 12 O'clock, then what is at 9 o'clock 180*? I thought this was the spine. Or is this basically saying that the spine is always 90* clockwise from the NBP and by aligning the NBP at 9 o'clock it already puts the spine at 12? But then that wouldn't hold true to me putting the NBP at 12 because 90* counterclockwise wouldn't be the spine, it'd be the soft spine no? Any of this make sense?

You can NOT go by a shafts logo at all. I can order a dozen shafts (any brand) Spine, flow, match, however you test them and you will very very rarely find 2 of them the same. Most tour players like a clean look to their clubs and choose logo down. This dose not mean thats the correct alignment. Believe it or not as much time we spend talking, reading, debating, this topic. I'm still yet to watch a tour van worry about spine when building a tour players club. There has to be something to that given all the research being done by manufactures.

Were can I get a FLO tester? I know that One Put on The Sand Trap Forum had them for sell But, That site is down.
Thanks

Ask Taylor Made what the best spine is for the R9 driver...

My R11S has the NBP at 1200/0600 a´clock, so the stiff part pointing at 0900/0300 a´clock.

Many built their own. Some used a drill chuck with a laser locked in where the drill bit would go. A good, solid clamp is a necessity while twanging. Aim the laser pointer on a wall or flat service a few feet away from the tip. Move the shaft around while twanging ((horizontally) while look for the flattest laser line. Mark the top center of the shaft with a line. Install the shaft with this line up and down at the 12  o'clock position when at address.

Wow, a lot on spinning. I put the raw shaft into a vice with two roller bearings and using a third bearing to pull the shaft downwards to put stress on the shaft and slowly spin the shaft to find the spine. You can tell by the way the shaft feels. The stiffest is the spine, mark it. I then put the shaft into another vise (no bearings), clamp it. I attach a shaft weight and laser to the tip of the shaft (I bought the tip from Golf Works and used a cheap laser and attached it with plastic ties), then pull and release the tip and watch the laser beam.  If the beam goes up, down, around, it is not true. Turn the shaft, clamp it again, pull and let loose watch the laser beam, when the beam goes straight in a horizontal line with no wobble, it is trued, mark it and mount it in the club head just that way. I have had any problems with this method. Works with graphite or metal shafts.

Bearing based spine finders have been proven to be unreliable.

FLO is more reliable - but only if you have a frequency meter since both the spine (strong axis) and NBP (weak axis) will FLO true.  The frequency is needed to tell you which is which.  Otherwise it's pretty random which one you may be aligning and you can get inconsistent results.
