![]() ![]() 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. And last but not least, if your entire set is spine aligned, then your clubs should play more consistently club to club.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. However, for sure, many of the top clubmakers, many shaft experts, and many really excellent golfers are convinced that the location of the shaft's spine in the golf club will have an affect on the overall performance of the club including having an affect on shot dispersion and accuracy having an affect on results from mishits and most definitely will affect the feel of the club. We're not aware of any hard data that proves the validity or significance of spine aligned clubs. The shafted club with the properly aligned spine position moves in a much straighter path. the shaft/clubhead bounces all over the place, in about 50 different directions. Then try it with a club that is NOT properly spine aligned. The clubhead moves rapidly back and forth in a reasonably straight path. ![]() It is interesting to clamp down a properly spine aligned club into a club vice, and pull down hard on the head, and release it. You get a stiffer reading when the spine is oriented the direction the shaft is deflected.) The theory of spine aligning is that the golf shaft will perform better if the shaft is aligned in the clubhead so that the spine is "downline" with the direction of the golf shaft (so the spine would be in the 3 o'clock or 9 o'clock position - also called the neutral position.) Indeed it does seem to make sense that if the stiffer spine is in the 1 o'clock position within the shaft (or 2 o'clock, or 5 o'clock, or 7 o'clock, or 11 o'clock, etc.), then it is highly likely the shaft won't perform as well as if the spine is in that downline 3 o'clock or 9 o'clock neutral position. (Nobody should argue that the spine is not the stiffest part of the shaft, but proof can be seen when rotating a shaft on a frequency machine. The process normally takes less than 1 weekįirst, every golf shaft has a "spine", and that spine is stiffer than the rest of the circumference of the shaft. You also have your choice of ferrule color. I guarantee that my tolerances are as good but (what I have found) in most cases better than anything you'll find in a brand new retail club. Any weight lost through the refurbishing process is returned via lead tip weights. I apply the same concept to my golf clubs. It was possible to pick up real horsepower gains simply by taking a stock engine apart and putting it back together the way it should have been in the first place. ![]() Balancing & Blueprinting is an old school muscle car term from the good old days when manufactures played fast and loose with tolerances. ![]()
