2-G Hinge Motion Question
 

On Page 28 of the 6th edition, HK writes "Doing the above drill with Zero Accumulaor #3 (6-B-3-B) will show that then, all Lag Loading and Hinge Action have Angled Hinging Travel AND Rhythm. So--intentional use of Zero Accumulator #3 can be useful while unintentional use can be hazardous."

Could someone expand on these two sentences? I understand the different hinge actions, but I am in a fog as to what these two sentences mean.

I don't know if this is what was asked but..... and someone correct me....


If you zero out acc#3, no cocking of left wrist or hold the shaft in the palm of the left hand which does the same thing. The clubhead can not lag behind the hands- it can only turn in line like the end of a screw driver. Once acc#3 puts an angle on the left wrist, the clubhead is activated with Lag.

Without acc#3- you just own a big long stick from left shoulder to the clubhead.
With acc#3- you established a Lever, a machine- Lag and Rhythm.

Of course zero acc#3 in putting is useful intentional use.

Check out the video- ..”R U Ready to Roll?” Lynn demonstrates the acc#3 transfer power when he smacks the desk with the dowel.

6bmike, I like hitting basic motion with left palm grip. Actually, I do think it is more difficult to use horizontal hinging and swinging with this grip. That is probably why I like to switch it back for swinging.

It does form one 'big long stick from clubhead to left shoulder' exactly like you said. But isn't this the primary lever assembly ?

With accumulator #3 you add another lever, the secondary lever assembly.

I can still produce lag and rhythm at stage 1 without accumulator #3. Or at least I think I can. Isn't rhythm associated with hinge action....so if we have one we have the other ? I'm not sure about that.

How long have u been studying TGM? I have just been reading these sections in my new book and you seem to have it really down. Nice job! How's your game coming?

Lag, Hinge Action, Rhythm
 

With a number 3 accumulator- horizontal hinging has the longest arc travel of the clubhead, angled hinging less, and vertically hinging even less. That travel and the time it takes to cover that distance is the RHYTHM. Even further removed from that travel is that the lag loading and method of acceleration creates certain kinds of travel inherent in that procedure.

That said, when you have no #3 accumulator- regardless of the lag loading procedure, and regardless of the acceleration method, and regardless of the inherent hinge action in that procedure- or even if you are manually over-riding with a selected hinge action- it doesn't matter if it is horizontal hinging (normally the longest travel), angled hinging, or vertically hinging (normally the shortest travel), all of them will have the same travel with the zero #3 accumulator that the angled hinging has WITH any amount of number three accumulator.

That's fine if you understand that- but if you were unaware of it- that could be a problem because you might have other components trying to coordinate at a different Rhythm- travel time and distance covered- than the Rhythm of the #3 accumulator. Or put in a different way by Homer Kelley himself in 6-B-3-0 "The Turning Rate of the Pivot Components especially the Shoulder Turn as actuated by Hip Action (7-15) MUST be identical and synchronous with the #3 Accumulator Roll, else its Rhythm gets disrupted. or at least difficult."
