A free read of sorts...enjoy.

Hands at the top
 
The author emphasizes the need to have the palms horizontal to the ground
at the top so that during the downswing the hands will drop more easily into "the slot." I can even see how this would add a lot of power accumulator 3(?-rolling of the forearms), but I thought the palms were supposed to be on the plane, and the end of the club closest to the ball was supposed to point at the plane line/target line. The two here seem incompatible, remembering that not everybody can get the club parallel to the plane line at the top.

Anybody tried Gerry Hogan's shaft the nunchuk? What did you think?

Homer liked his shafts as stiff as possible. Knudson liked them as stiff as was absolutely possible, super heavy at the head and counter balanced back to a normal swing weight. Kev Carter has gone back to x stiff, Bucket likes triple x movies.

While the underlined text on pgs 27 and 28 can work, to say you must do this is patently false. Much better to say the palms should lie in the plane of the LFW.

Hey Joe

Know what you mean. You'd assume that given the definition of the LAFW. But wouldnt it be better to say the palms lie flat to the Inclined Plane at Top? (Assuming a 10-2-B grip) Which would give you a cup at the left wrist unless the inclined plane runs through the Turned Left Shoulder.

Hogan's Ally
 
Thanks Justin. The Hogan Book is an excellent read. I have the book and recomend it to any seriuos student of the game. Unfortunately, the first few chapters did not print in your attachment. They have quite a bit of Homer Kelley in them: "the human body in motion is a mechanic apparatus" and Hogan's explanation of Hand Control Pivot hits the nail on the head, "what you intend to do with the hands dictates where and how the arms move".

Hi OB,

You're probably right, I have a literally flat wrist at the top and forgot that many do not!

I know I used to too.

What is a "flat left wrist"? It aint necessarily visually flat to my mind. This is a big big thing for people reading Homer. Something guys get wrong often. Spent a good deal of time talking about just this with Yoda a few weeks ago.

In short a left hand grip that shows a couple of knuckles or more at address , given a pure vertical plane of left wrist cocking motion .... should show a increased cup at Top. Try cocking your left wrist vertically up from address over your left shoulder without turning your shoulders and see what you get cup wise. This is what Lynn teaches, I believe. Left Palm flat to Plane. The clubshaft laying flat on the plane , cocking up and down the plane. The Left Palm laying flat to the plane at Top and during Drag Loading.

I must admit to some issues with the definition of the LAFW as it nears Top. Personally I choose to plane the club and left wrist to the Inclined Plane rather than to the Left Shoulder at Top. Through impact I can see things as per usual but at Top ....no.

I dunno.

I have a very weak grip with the thumb on top of the shaft, which simplifies things a lot.

Then with that grip type a Purely Vertical Left Wrist Cock Plane of Motion could have a corresponding visually flat left wrist at Top. For golfers with "stronger" left hand grip types than Mizuno Joes "very weak" left hand a visually or literally flat left wrist Top can only be achieved via the introduction of some Horizontal Left Hand Motion......a less than ideal thing. Some "arching" say.

"Flat" in Homer speak is not necessarily literally flat .... The Left Hand at top must correspond to the grip type employed . Which for most means there's some degree of a " cup" present.

But here's my head scratcher: Given the above and assuming its desirable to have the left hand laying flat to the face of the Inclined Plane at Top , wouldnt this imply that there is only one Plane Angle available to the golfer absent any Horizontal left Hand Motion? Only one Plane Angle where he can cock his left wrist Vertically and get his Left Palm lying on the face of the plane?

For any inclined plane, the leading edge of the club has to be parallel to the plane of the left hand, if you want both to lie in the inclined plane at the top. So if you have a strong grip, you can have either the hand or the leading edge in the inclined plane, but not both, regardless of any hand manipulation.

I believe Homer would go for the left hand , given his notion of Grip Rotation......which alters the left hand to leading edge relationship progressively as the ball moves back of Straightaway.

Those guys who look at the face at certain points in the swing often dont take into account the amount of Grip Rotation. They only look for a certain relationship to the left forearm at top or a particular face position at Both ARms Straight without any consideration what so ever for the effects of Grip Rotation.

Still got some fog around this thing about plane of the left wrist cock and the hand laying flat to the plane though..........unless there is a "geometrically flat to the inclined plane" thing going on with Homer. I dunno.

Apparently, me too. I noticed yesterday that even with my ultra-weak grip, when I go to a literally flat left wrist at the top, the clubface is still slightly closed, which would explain why I'm continually fighting pull hooks.

If anyone is interested I have a Ping G10 golf club with a Gerry Hogan Shaft for Sale. It is the predecessor to the Nunchuk shaft. It is a rare shaft, and there are only about 5 in the United States, and they are no longer produced. Price is negotiable. If interested email me eddycossio@yahoo.com.
