Mike that is a nice visual, but if you were to use Kelley's Plane board, it doesn't work as written in chptr2.
Very simple, Kelley stating that the shaft remains on or against a flat plane and this concept creates two different planes that intersect at the grip, the sweetspot plane being the flatter.
I believe that chptr 2 is very problematic, Kelley needed more words and diagrams.
I know I sound like a broken record on this topic, but I have tried and tried and can not make his statements work as they are written. Something is missing, much like what is the reference point of the camera regarding CF in Kelley's descriptions.
I really believe that Kelley would not intentionally use a device or recommend a training aid that would contradict his intentions, the use of the plane board and the use of the park bench (drill) just doesn't support the plane being defined phyically by the sweetspot.
I will shut up now. (it has been almost a year since I argued these points)
When the club is "turned to the plane" - are the sweetspot and shaft planes the same?
