Yoda - you wrote-: "the Right Forearm supports the On Plane Loading".

You are right. I forgot about that point. I now recall one of your archived posts where you wrote about a strut supporting an airplane wing (which is a good analogy).

To summarise what is meant by the term "Magic of the Right forearm" it includes-:

1) The right forearm supports the on-plane loading of the primary lever assembly in hitters and the secondary lever assembly in swingers.

2) It acts together with the bent right wrist and PP#3 to keep the clubshaft on-plane throughout the entire downswing (via tracing the SPL action).

3) It gets on-plane as it paddlewheels into impact thus supporting the clubshaft at impact.

I think that one can see the 'magic of the right forearm" in action in Stuart Appleby's swing.

I produced the following series of capture images from that video and highlighted the right upper limb in red so that one can concentrate one's visual attention on the right forearm.

Backwsing



It looks like he is using a right forearm takeaway in images 2 and 3. It looks like his right forearm is supporting the load of the secondary lever assembly in image 5. Image 4 shows how the right forearm takeaway can keep the clubshaft on-plane during the mid-backswing.

Downswing




Images 1, 2 and 3 show how the right forearm acts to keep the clubshaft on-plane during the downswing.

Images 4 and 5 show how the right forearm paddlewheels to an on-plane position behind the clubshaft as it nears impact.
