Basic Motion

[O.B.Left]

Thanks O.B.- Yes, I do own the book. 2 copies. the one I refer to most is very dog eared, many loose pages, many colored highlights, 3 or 4 rubber bands to hold it together.
Although I am trained as an engineer I need a forum to work through understanding. I also use all the video clips I can find because they demonstrate LB and other teaching and their understanding of HK's book. Putting is an individual thing and I do not subscribe to it as part of the process, but thats a different story. I took up golf in the early 60's (yes 50 years ago) and learned on my own to "wail the hell" out of the ball. Locked arms, locked wrist straight arms. turn it up and back and crank it down and around. 250-260 straight, wood headed driver, and somewhere I could find it. 1/2 hour on the practice tee an my feet would screw into the ground 4 inches. Often shot in the high 80's at the likes of Torrey Pines South- was $4 green fee in that day and Billy Casper was the tour Pro. But I have not played a lot over the years. you know family etc are more important. I am retired and live in NH. I have pulled the clubs out and decided to do some serious (read correct) swing work this winter as I plan a long family vacation to the west coast next summ an I may even take my clubs. But I want to do it right this time.

Yes, welcome HungryBear. Now I'm not the oldest!

Daryl,

In post 46 where do you get your definition of swivel?

Hinge Action is defined by the book as:
Holding the Flat Left Wrist Vertical to one of the basic planes will impart the same motion to the clubface.

Those motions are
closing-horizontal hinge
layingback-vertical hinge
or closing and layingback angled hinge

This is exacly what's happening in basic motion....the travel of the clubhead is the same when power accumulator 3 is zeroed out, but the hinge action can vary for the shot at hand.

Now you bring up the word swivel
First swivel is not in The 7th ed Golfing Machine Glossary
so we can go to 4-D-0 as reccommended by the index.
There swivel is defined as "actually rotate the left wrists" or later in the paragraph "actually rotate their wrists"

If we define swivel as a rotation of the wrists then all hinge actions have swivel even vertical hinge could be called a reverse roll or swivel.

Now if we look further into this passage it says that

Players must Swivel-actually rotate their wrists-to the parallel to the plane position for the finish after follow through.
We could then define a finish swivel as the rotations of the wrists into the parallel to the plane finish after the follow through.

This means there is swivel in all shots with hinge action, but there is not a finish swivel in a basic motion because follow through is the end of the stroke.

Also I would further state any shot with a flat left wrist has a hinge action.

I can't disagree. I can get by the Rhythm issue, but I just can't get passed the "Differences in Travel" issue.

The difference in travel is certainly related to the amount of #3, but that isn't hinge action or motion.

Hinge action is strickly a clubface/compression concept and ONLY applies from impact to separation. It is a ball/club relationship, nothing to do with the body or anything else at its root.

Line of Compression? Doesn't it depend on both clubface rotation and path?

It depends on force vectors, so yes the path is part of the equation, but only as related to the plane/plane line. The ball doesn't care about #3 angle per se. Your feel as a player may, but the ball doesn't care.

Perhaps this conversation can be moved to its own thread, as we are on a bit of a tangent from the original post.
