I use the club head as a tip weight and a laser pointer attached to the shaft to confirm the shaft is in the plane of FLO.
SPINE ALIGN GOLF MANUAL
When I align a shaft, I am aligning a plane of Flat Line Oscillation (FLO) and I take a similar approach to a manual version of the SST Puring™ procedure. However, unlike the SST Puring™ procedure that measures the uncut shaft, I carry this out with the shaft clamped at playing length. Given that most grips are in the region of 10” long and the clamp on my frequency meter is 5”, I am aligning the plane of FLO of the club from halfway down the grip, directly under your hands.

The plane of FLO with the higher frequency is orientated this way as the stiffness of the shaft is in opposition with the highest bending force in the golf swing and is also minimising toe droop. Most of the shafts I select have a negligible spine (difference in stiffness) that may be too small to be measured or, even if detected, too small to make a practical difference.Īs I will have already located the planes of FLO during the Shaft Certification process, I will initially align the mark from the FLO plane with the higher frequency in the 12-6 orientation and FLO the club with the club head attached.

This information comes from the Radial Integrity readings taken during my Shaft Certification process and also from the Shaft Selection software I subscribe to. I built 2 identical 5 irons, one with the shaft properly aligned and one with the. A spine is an inconsistency created during the manufacturing process where the steel or graphite shaft may not be perfectly round, straight or where the wall. I go out of my way to order shafts that are inherently round to begin with thus reducing the impact of spine alignment. When you Spine & Flo your shafts youll get more repeatable center.
