![]() Then I fired up my Maltby Frequency Analyzer. ![]() Sometimes I have found the FLO line to be a bit off the Black line, but usually not by much.Īs expected there was another FLO plane perpendicular to the one above, and I marked this with a Red line I marked this line with a Green line, even though the line was the same spot as the Black line above. I then FLO'd the shaft with my laser and one of the FLO planes was indeed exactly the spine as found by the bearing method. Let's not worry that a bearing spine finder might be fooled once in a while by some secondary spines. The "weld line" being the strongest part of the shaft ( AFAIK ). I view this Black line as the opposite of the "weld line". I will install the shaft such that the hard side of the shaft spine ( the "weld line" ) is at 12 o'clock as I look down the shaft to the iron-head.Īhhhch who knows, FLO & Spines could all be meaningless in the real world anywayīut what else can we do but think about useless things while we are restless, bored, and ride out Covid.Īny thoughts out there from you fellow enthusiasts and club-builders ?įor fun ( time on my hands ) I just took my 5i, and found its spine by pushing down on it with a bearing in my bearing spine finder. In my current build, I think I will ignore the FLO, and just rely on the Spine. ![]() I believe toe droop is real, unlike me having "blind faith" that FLO'ing is really important. With a Driver for example, a too soft-flex shaft, or tip-weak shaft, can lead me to have the head lagging behind at impact, toe down, de-lofted, and open, YMMV. What I am tangibly aware of, and have experienced, is toe droop resulting from softer flex, and/or tip-weak shafts. I really have no proof that FLO'ing has improved the quality of my strikes, my scoring, etc, but I sleep better at night knowing the shafts in my irons are FLO'd. So I've been FLO'ing shafts over the last couple of years:Ī) because I can, and have the tools to do so, andī) I've read it "may" be a good thing to do There is no complete oscillation cycle of a golf swing, so why do we think the FLO of a golf shaft is relevant ? Let's leave out of the discussion what happens post impact in the 6->3 quarter. AND each quarter is under the same influence of force ( gravity ).Ī golf swing is just 2 of these quarters, the 6->3 take-away, and the 3->6 down-swing, both under vastly different human induced forces. We can break down the weight's path of travel into 4 quarters ( 3->6, 6->9, 9->6, 6->3 ). If I had a weight suspended by a string, 1 full cycle would be raising the weight to say 3 o'clock, letting go, let gravity take it all the way to 9 o'clock, then have it return to 3 o'clock. When we twang the shaft and see our laser pattern, that's all fine and dandy, but twanging a shaft and the resulting continual oscillation is not a golf swing. The shaft will also flex in another plane(s) because the CoG of the head is not inline with the plane above. The shaft will flex in 1 plane because it is under the forces of the swing. What creates toe-droop ? -> the Center of Gravity (CoG) of the iron/driver head is not inline with the shaft. I've FLO'd several sets previously, but am now rethinking what really is important, hence this post. ![]() I have a bearing Spine Finder along with a chucked Laser for FLO'ing, and have read most everything on the subject over the last few years. This is the main reason premium shafts are very similar and when you buy a new 3 wood to match your driver you can feel pretty sure performance will be the same, where you could get 2 radically different performing shafts going the cheap route.I've had a full golf workshop at home for the last 2.5 years, and now at the epoxying stage of my latest build for this season's clubs. And obviously this also meant the shafts that flowed much better were more consistent from shaft to shaft while the ones that wobbled were all over the place. So Floing only exposes the quality of the shaft, not it's potential to stay on line when swinging it. Cheaper shafts of poorer quality began to wobble quickly but of course we only swing our driver once. Aldila stopped orienting shafts as they thought it was a wast of time. But high speed photography showed that every single shaft, regardless of orientation produced a perfectly straight line on the first pass. But I played a round with the VP of Engineering that designed the NV as well as many other shafts and they used to align their shafts at the factory. Seemed pretty obvious to me there was an advantage to Floing driver shafts. Fwiw, I also used to Flo my driver shafts and was amazed at how badly some stock shafts wobbled while premium after market shafts stayed more in a straight line.
