    Sustaining the line of compression

    Dave Kelly at his first participation this weekend in a PGA event - the Ford Championship at Doral - had an interesting experience on the tenth hole. The head of his driver, a Nike, Sasquatch, completely separated from the shaft and was found 70 yards further away in the fairway. The driving...

    Putting - offset impact

    Seeing the present posts on putting reminded me of some ideas I have posted on another forum quite some time ago. With putting there is a lot of feel and it is hence interesting to use some objective mathematics to have a closer look at the issue of offset impact.

    Sweet Spot Plane

    – Homer in, 2-F. PLANE OF MOTION, defines a dynamic sweet spot plane separate from the shaft plane. – Yoda to Martee: “Remember, Martee, don't confuse the Clubshaft's Impact Plane Line with the Sweetspot's Impact Plane Line. These are quite different!” I got intrigued and had a closer look...

    Power Accumulator – science or metaphor?

    Probably like many who have Homer Kelley’s book laying around, I do pick it up once in a while, but get each time very quickly impatient with the circular referencing, feeling I am getting trapped in a labyrinth. It is interesting to observe that the TGM forums conserve this particular aspect...
