Release with Extensor Action/Throw-out Swivel Release with Extensor Action/Drive-out no-Swivel Demonstration 1 - Swingers: Right Arm only. Place your Right Elbow at your side, bend your Elbow 90 degrees with the Right Palm facing up.Lower the Palm while keeping the Elbow at your side. This is Extensor Action. So, straightening the Right Arm by lowering the hand caused the Clubface to change its Alignment from On-Plane to Vertical for impact and the Right Hand became Aligned with the Elbow and Right Shoulder. Extensor Action without the #1 Accumulator. So, the Release Swivel begins when the right arm begins to straighten (Release) and Ends when the Right Arm is Straight (Both Arms Straight). Demonstration 2 - Hitters: Right Arm only. Place your Right Elbow at your side, bend your Elbow 90 degrees with the Right Palm facing up.Straighten the Right Arm by pushing the Hand away from you (Don't lower the Right Hand). So, straightening the Right Arm by pushing the Hand away caused the right Elbow to move into a straight Alignment with the Hand and Shoulder. Straightening the Elbow by using the #1 Accumulator does not change the Vertical Clubface Alignment. Extensor Action with the #1 Accumulator, no Swivel. These demonstrations can be easily performed On-Plane with the Right Forearm Flying Wedge. I think that a lot of the confusion occurs while trying to understand and use Extensor Action. Extensor Action is not the #1 Accumulator however, it does use the same muscle group and they can be used simultaneously. Thanks Daryl I now realize that we have much different geometry. my left stays flat, wertical and moveing from cocked to uncocked-release to both arms straight. My right stays vertical, level and bent and only releases bent as necessary after impact. This, for me , is dual horizontal hinge. The bones in my forearms do not change their relative position, release to arms streight. We therefore have "differences" in extensor action application. I thing I am OK with what HK wrote.
