Question:
Mike, in your travels through the maze of spinedom, have you been able to draw any conclusions concerning the spine location in relation to the label on the shaft? Is it totally random or is it close? Some shafts better than others in this regard? thanks tom

I’ve never had a logo end up on the top of the shaft (12:00 position) after spining if that’s what you mean. They’ve been all over the place. The closest I’ve had is about 10 degrees off 12:00. So as far as being better…I don’t understand. If it’s off, it’s off, and close in this sense only counts in horseshoes. To see why, put a shaft in a clamp, and find FLO with it. Then, rotate the shaft about 5 degrees; twang it again, and see how much wobble you get. Go another 5 degrees and twang again, note wobble. You don’t have to be off by much for it to induce a significant wobble, though how much will depend on the shaft. This is why it’s very important to get the shaft lined up w/in the clubhead to as high a degree of accuracy as you can. See how far off FLO you have to be for the wobble to set in; that’s how much error you can have in installing the shaft in the hosel. You need to be very accurate doing that. Supposedly a couple manufacturers orient their logos to the spine, both in the 12:00 position. Seems to me I read about TT doing it w/ the bimatrix, and UST with the Proforces, but in neither case did I find that to be true. The bimatrix was about, oh, 10-15 degrees off 12:00, the Proforces are all over the place. Even so, where the spine is located is not as relevant as where FLO is. And FLO is often not, in my experience, exactly 90 degrees away from the spine. Mike Mike Dalecki RSG-Wisconsin 2001 Info: http://dalecki.net/rsgwis I do not patronize spammers! Help keep RSG clean.

Very limited experience (3 or 4 of each for Penley shaft, UST 65 and EI70) but in ALL cases (repeat not a lot, maybe 10 shaft it’s not a statistically valid value and they were all very good ones) the logo has been in its "natural" position. It’s very strange… I’m starting to think that better shaft are more or less aligned by default… Greetings from Italy Massimo – Hide quoted text — Show quoted text – Is it totally random or is it close?

Mike, I’m sure some of your previous posts have mentioned this, but I had a couple of questions regarding some of your adventures with FLO. I tried to FLO a couple of shafts in my bench vise the other night and found it wasn’t as easy as I’d hoped. I was concerned about damaging the shafts with the vise jaws, but any material softer than the jaws seemed to dampen vibration to the point that I couldn’t be certain of my results. I seem to recall you have a clubmaker’s vise, but I’ve just been using the rubber clamp pad in my bench vise. I’ve been going make a jig out of hardwood, but thought I’d ask if you’ve already been down that road? OK, now lets assume I’ve found FLO. I assume that FLO is oriented with the target line, i.e. 9:00-3:00? May your next round be your best round.

I originally tried finding FLOs in shafts with a speed clamp I have–it has very generous rubber jaws, and I just wasn’t able to get the shaft clamped tightly enough to do it. I also have a clubmaker’s vise with which I *am* able to clamp shafts tightly enough. I’ve never tried doing with the cheap ‘prox $2 rubber clamp you use to cushion the shaft in a vise, but it has about the same amount of rubber as my speed clamp; I’d expect it to be less effective. I think making a jig out of hardwood (or even softwood, which might be better) is a good strategy. The club clamp for my frequency meter (http://www.dalecki.net/spining/clubclamp.jpg) has a two metal "V"s that hold the shaft; the knob has a slip-clutch in it to prevent overtightening. Since that works OK, I’d think you’d be fine with the wood. Just don’t overtighten (but you knew that, right?). BTW: IF I were making a wooden jig for this, I’d set it up so I had lips on top of the blocks to hang on the vise, so when you loosen the vise to rotate the shaft they’d stay in position (trust me on this). Loosening and turning the shaft at the same time is a two-handed job, you can’t have the blocks slipping down between the jaws each time.

Yep. Just recognize that there should be two FLO planes in a shaft, at 90 degrees to each other. But once you find a FLO plane, yes, it should be oriented in the 9:00-3:00 plane.

It’s interesting that UST claims in their FAQ in relation to spining that they "locate a stable plane of the shaft and apply the graphics accordingly. We recommend that the graphics be installed up (12:00 position) or down (6:00 position)". Having said that, I had my driver with a UST Proforce 75 shaft spin aligned recently, and the graphics ended up about 15 degrees from the down position. My shaft was one of the earliest UST Proforce 75s (I’ve had it nearly two years), so they may not have spine aligned their shafts/graphics at that time.
