moonsole Posted February 16, 2005 Report Share Posted February 16, 2005 I have read that the Pureing process can be pretty inaccurate due to the human factor involved. From what I understand the shaft is put through a series of tests by computers and software but then a guy/operator simply eyeballs the spot and marks it. Is this correct? If not, please indicate how it is done to obtain a higher amount of precision. What about the pre-pured shafts? Specifically the rifle pures and the rifle pure and balanced. Do they come marked so you know where to install them at 12 o'clock? And is the only difference between the two rifles the fact that the rifle pure and balanced has weight added to the butt and isn't jet black? Finally - could somebody please give a one to three sentance definition of the following terms: 1)Pureing 2)Floing 3)Spining Sorry. I thought I understood these terms and processes better than I do. Thanks in advance to any and all who help. Quote Link to comment Share on other sites More sharing options...
NickBooras Posted February 17, 2005 Report Share Posted February 17, 2005 I have read that the Pureing process can be pretty inaccurate due to the human factor involved. From what I understand the shaft is put through a series of tests by computers and software but then a guy/operator simply eyeballs the spot and marks it. Is this correct? If not, please indicate how it is done to obtain a higher amount of precision. I've seen the STT method down at Golfsmith in Austin, and yes, there is a very considerable human factor involved. Basically, if the process is still the same, they lock the shaft in the the computer/machine, and it tells the operator to turn the shaft left or right X degrees. When the computer says all is well, the operator places a sticker on top of the shaft where he "thinks" 12:00 is. It's fairly accurate, but when you test the PUREd shafts, they are slightly off 99% of the time. What about the pre-pured shafts? Specifically the rifle pures and the rifle pure and balanced. Do they come marked so you know where to install them at 12 o'clock? And is the only difference between the two rifles the fact that the rifle pure and balanced has weight added to the butt and isn't jet black? Yes, they do come marked so you install them at 12:00 for righties, or 6:00 for the lefties. With regards to the rifles, I don't have any experience, so someone else will have to answer this. Finally - could somebody please give a one to three sentance definition of the following terms:1)Pureing 2)Floing 3)Spining Sorry. I thought I understood these terms and processes better than I do. Thanks in advance to any and all who help. Someone correct me if I'm wrong here: When a shaft is made, graphite or steel, there will always be a hard side and soft side in the shaft due to the manufacturing process (wrapping graphite, for example, starts and stops somewhere). Because of this non-uniformity, in addition to the shaft flexing on a plane toward and away from your target, there will also be some vertical motion in the direction the hard and soft sides are aligned in the club head. Finding the hard spot, or the spine, and placing it facing your target will, in theory, eliminate most of the vertical motion in the shaft, thus eliminating another inconsistancy in your swing/clubs. It's my understanding that Puring is just a computerized version of Spining developed by STT, but I don't really know the whole story, to be honest. As for "floing", I've never heard the term, so someone else will have to field that one. Quote Link to comment Share on other sites More sharing options...
moonsole Posted February 17, 2005 Author Report Share Posted February 17, 2005 Thanks for the response. From what I've learned Spining seems so much like Pureing. Quote Link to comment Share on other sites More sharing options...
Guest Posted February 18, 2005 Report Share Posted February 18, 2005 Thanks for the response. From what I've learned Spining seems so much like Pureing. same general concept - different process. i think there's another proprietary method out there that vijay uses.

ShreveportGolf Posted February 18, 2005 Report Share Posted February 18, 2005 "Flo" stands for flat line oscillation. When you "spine" a shaft, it may have the human error involved if it is simply installed where the mark is placed. However, if you take the shaft and add a laser pointer at the end (after it is spined and the head is temporarily affixed), when you twang it in whatever direction you desire (NBP to target or hard side to target) you can manipulate it to where it will not wobble. Basically, you can tweak it to where it will bounce on a straight line. This will give you either the most accurate results or the fastest release of the club, depending on how you like it. Accuflex manufacture their shafts on a mandrell. The process is called fillament winding. I have tested these shafts and no matter how you turn them, they don't have a hard or soft spot. However, I have talked to several manufacturers and they claim that there are positives and negatives to any manufacturing process. So, take that with a grain of salt. I hope this helps.

golfpro57 Posted February 18, 2005 Report Share Posted February 18, 2005 [/colo shaft orientation is still an iffy thing depending on who you talk to. flo'ing and spining have been around for some time, Pure'ing is relatively new and is done by a computer and is fairly accurate, the best I've found is Peeking, done by Advanced shaft in Houston, its a relatively newer method and its all about locating the centroidial axis of the shaft. I've had this done to my present playing set and it really works, The Miss hits just go further and closer to the target. www.advancedshaft.com Quote Link to comment Share on other sites More sharing options...
