yeah, I’m back again like a bad cold:-)
I purchased a couple of wood shafts from Golfworks and had them pured. Mostly for educational purposes. One was a Fujikura Vista Pro the other a Maltby UL Pro Series. I did CPM checks to establish profiles and the such from Butt to 11″. I did polar plots for consistency in 5* increments. I put them through a spinefinder (which i think is a NBP finder) for Sh!ts and giggles. I also did FLO tests, which I discovered is a pretty good representation of SST Pure on the two shafts I used.
With the Pure Line (PPOP) at 12:00, I had good FLO in the horizontal direction on both shafts, in two seperate planes approximately 90* out from one another. I was also pleased to see that the Stiff side of both shafts were along the target line (the Maltby at 243 cpm vs 240 cpm, the Fuji 236 cpm vs 233 cpm).
I did notice that on the Maltby shaft the plane of the White Line was the stiff plane (243 cpm) and the weak plane was the Red Line (240 cpm) – also the PPOP was 180* opposite the Red Line – the same plane, which I can grasp.
My concern is I understood from the previous discussion “when the white line is up, the stiff side is towards the target”.
I also found a previous comment from Jim when discussing Maltby Pro Series Graphite Iron Shafts regarding the installation:
These shafts are tested for a vertical oscillation plane at the factory and marked with a white line on the butt end of the shaft. They then rotate the shaft 90 degrees and mark the shafts with a red line. During installation you would put the red line on the top side of the shaft and this puts the oscillation plane going to and from the target when you swing the club.
Now, I’m going to put the shafts into clubs with the SST PPOP at the 12:00 position, I’m just confused on how to interpret the Red Lines and White Lines on the Maltby shafts in the future. I noticed in Jim’s comment he doesn’t mention whether the oscillation plane is the stiff plane. I’m hoping Britt can clarify.
