While I am, if anything, known to be a wordsmith, not an engineer or physicist, I nevertheless must risk asking the obvious, perhaps, concerning IRON BYRON – the most nearly perfect way to swing the golf club. As you ingeniously discovered, IB is the best model to use. He demonstrates the three key elements in the best way to swing – Circular Body Rotation, Unrestricted Hinge, and Constant Forward Axis Tilt.
My question concerns the Hinge. Since IB’s arm is attached to his Driveshaft, it can only rotate in a
circular arc as his Driveshaft moves. The arm otherwise can only provide motion by hinging and
unhinging the club to provide power at impact to release. Since the club starts at 180 degrees [parallel] to downswing plane, and squares up to target line at impact. it must be able to rotate 90 degrees in the process, it seems. Since I cannot see the attachment hinge in either the BMG book or DVD, this is my conclusion.
Our human arms, of course, rotate 90 degrees from setup to top of back swing, and again from the top down to impact and release. So it would seem that IB must have a swivel of some sort where the club is connected and hinged. Am I right in this understanding?
Thanks for your patience in dealing with this question.
Don’t over think the machine. I’ve had people do this for years. The whole point is to make it simple.
The machine has brakes and gears in its hinge. It was designed to test clubs so it has to be 100%. At first it when the hinge was totally loose it would snap the shaft off in the ceiling ever time it swung.
You are forgetting mass wanting to swing to its widest point. If the arm started straight and the face square even without gears it would swing to its widest point which would have the face square because this was pre-determined at setup.
Pros are only 70% because we have 2 legs and move between them. So we do not turn in a perfect circle. The machine does.
Thank you so very much for your simple but clear answer. It makes total sense to me, but I was too curious not to be sure. I have always preached “KISS” myself as a teacher or coach, but have not always followed it. While this information is not required to swing perfectly or play well, it does help
perfectionists/cerebral guys like me to feel more complete and confident when I do know.
Thanks again, Paul, for your patient and professional attitude and assistance.
If I do not happen to feel a need to ask about something again [With thousands of Tips],
Please enjoy a Merry Christmas Feast of Love.

Paul WilsonJohn,
Glad I could help. I like to put it in ways people actually understand. I would rather be too simple that too complicated.
Have a great Christmas too.
