Iron Byron – Throw Release ‘Cause Science…

iron byronYes, the machine known as the “Iron Byron” has a throw release, because, “Science,” of course.

It’s easy to dismiss the notion of swinging with a motion like Iron Byron because, of course, we’re not machines.

And anyone who claims to have a swing model like Iron Byron’s, is of course being absurd, but I imagine it sells… we swing like living machines, and with two arms.

But there are things in the Iron Byron construction and motion that are straight out of kinesiology as well as physics, because really, kinesiology is the physics of human motion.

For one, Iron Byron’s “throw release” down swing.  See if you can spot what I’m looking at here.

And for the “pullers,” guess what?  That same action is the “frisbee throw” action of the leading arm.

Oh, and another point!  This is the same action as the “sledge-hammer” or “push-pull” hybrid swing motion…

See what I’m saying?

    Just watching the Iron Byron gif repeatedly helped my understanding that the head must be steady and no swaying should exist. Also, I see the importance of “staying back” on the downswing- something I have a heck of a time doing as my instincts want me to hit with my shoulders. That machine ain’t swaying back or forward it just stays put.

    Something worth considering, back when the trebuchet was being developed they determined that the machine was more powerful, apx 25% more, when it was on wheels and was allowed to move relative to the throwing and weight dropping action. The ability to remain fluid in the swing has a similar effect vs. attempting to be “fixed”.

      That’s the origin of my term “trebuchet drop” from years ago JB – I was watching a documentary on medieval times, probably back in ’05’-’06 (right around the time I began my swing research, but not sure on the exact year), and the trebuchet catapult was discussed, including the part about the wheels giving the machine more power and accuracy.

      When I noticed that the very good power swingers’ heads moved down and back on the down swing into impact, I figured that this was a good term to apply to it.

      I’ve always looked at the trebuchet when thinking of leverage and power generation…

      So, you want a “trebuchet drop” with the head if any motion at all, and you don’t want the “harpoon dive…”

      Seems pretty simple to me!

    Perfect release.

    The club head is moving around the hand without resistance while the arm is swing in a larger circle. Perfectly timed and in unison. You can tell because the club is pointed up before the arm reaches 3:00 on the follow-through.

    Nothing is holding that club back

      Pretty sure the gurus would call that a flip… which shows exactly why golf swing instruction is in the state it is in. Everyone has a “new” concept, when the “old” one was correct all along.

      You can’t reinvent the wheel – it’s already round

    There’s only one thing to learn from an Iron Byron. The key to the machine is that it produces speed…specifically, angular velocity.

    If you measured rotational velocity inwards from the “arm,” at the “body” or hub…and then compared with the velocity of the clubhead, you would find that the clubhead is (of course) traveling at a much greater rate of speed. That’s it.

    The Iron Byron was created to mimic a human. Iron Byron only has only one leg and one arm. A human is a lot more complex than a machine. Luckily, we don’t have to know about the complexity.

    There might be another thing we could learn. Iron Byron probably releases from the top (as Nicklaus claimed to do)…does not “hold the lag.”
