Here We Go
 

After a brief, friendly, quiet interlude, the attacks on a centered pivot start again. Now let's go after Ted for posting a video with a bottle on his head. All you can do is laugh...

What? Golfers move their heads?

Like a lot of endeavors you start with a model, some assumptions and then later you change the parameters to see how it affects things and what compensations may or may not be required. The basic model still has merit, relevance though especially to the subject in its simplest form........like putting say. That said, Bobby Locke swayed when putting ..... but compensated for it.

In an actual human swing , Homer identified multiple centers , most, maybe all but one, are on the move actually. Given this , he knew the clubhead's orbit wasnt perfectly circular for instance.....but the underlying geometry , the Geometry of the Circle is golfs geometry and you cant draw a perfect circle without a constant center. Which makes for a good starting point for a golf model. Like in 1-L, The Machine with its one steady Center and its one Lever.

Next week lets discuss why the model doesnt have feet or legs and how to cut ours off. The following week let's cover attaching a giant hinge to our left shoulder and why airplanes should have feathers.

I actually think there are plenty of good swings where the head moves, but I see more good swings I like with a fairly centered head... Isn't it about what works for each student? When someone starts screaming from the mountain tops that a "feel" doesn't pass scientific muster I run away, and will continue to do so...

Can you imagine trying to make Bubba Watson swing like any template? I sure can't. Centered works for me though, and am seeing a lot of success with teaching my students a centered pivot. Things move when you see them in 3D, but that doesn't change the "feel" or the goal of getting on top of it...

Good stuff Kevin, the head moves even when you feel that it does not. I have a tough time getting my head back to impact fix once it has moved too far to the right. I set my head at impact fix, move everything else into an adjusted address and usually don't think about it again. Works better. Also, when the head is still on my backswing, my pivot is more efficient. Check out some youtube videos of Robert Allenby, that is the head motion I refer to.

Thanks Dodger,

So many of the Australian's swings look so simple and efficient to me. Allenby, Appleby, Elkington, Pampling, Badds, the list goes on and on... :salut:

Good find Air! :salut:

Here is what our "cult" leader had to say. Pretty hard to argue with this no matter which side of the coin you fall on...

"HOMER KELLEY viewed the Stationary Head as a geometric ideal, not as a mechanical absolute. He recognized our humanity. Hence, his advice: 'Just keep it as still as you can.'"

Since I am new to posting here if this sounds confusing I apologize ahead of time. If the head cannot remain perfectly still during the swing and even Homer ( if I understand him correctly)basically says to do the best you can to keep it steady, isn't this somewhat a case where "seems as if" produces the feel of a still head that we are trying for even if it is not really still.

That's how I see it paspilot. Science is great, but we don't swing in a test tube.

Kevin

I am not trying to keep my head still consciously but its a pretty good indicator that something is not right mechanically if its moving around.

Here's something Ive been noodling over.

Say the Left Shoulder was the center of your Left Arm and Club's (The Primary Lever's) swing. And say you previewed your exact desired Impact position prior to taking the club back in Startup (Impact Fix): Your ability to return to this exact Impact Position with your Left Shoulder hitting its mark would define how consistent your clubhead orbit was through the ball right? If you were building a machine you'd incorporate some sort of fixed center for the shoulders to rotate around probably. A place directly between the shoulders ideally or for us humans lets say around the nape of the neck but inside our bodies. You could call this an alternate Pivot Center which since the head is above it means the head would move a little given Hula Hula, Hip Slide and Axis Tilt right?

So if at Address you centered this Pivot Center between your feet, held it constant and slid your Hips a little bit towards the target (like some guys do for mid irons on down) ......would the head not move back of center just a tad given the tilt of the shoulders? Would the head not wobble about ever so slightly as you held this other pivot center steady to the best of your ability during the swing?

Here's Homer at Fix: dont think the camera is quite square to him or the ground for that matter but his head is back a tad to my eye. There's a guy I know whose swing I really admire that goes from a Fix like this to moving his Arms back to Adjusted , keeps his Hips slightly slid target wards prior to Startup. Maybe undoes the Hip turn a bit to make his Right Hip clearing smaller. I really like this for mid irons personally. 10-9-C HALF AND HALF, for all you book literalists. He sorta presets the weight left..... really nice centered motion. Much easier to do without excessive Pivot Motion which is far too common.
