I can't see where Homer could possible have gone wrong with his dissection of impact and ball compression in TGM.

HK's discussion of impact was very theoeoretical. I think we need empirical data to sort out how much small variations in the impact alignments matters to the energy transfer.

In any case I think HK's explanations here tells a lot about the difference in quality of ball striking between great players and high handicappers.

It may appear that the difference between a draw (with as close to perfect impact as it gets) and a fade (where the club face rotates anti clock wise and the ball rotates clock wise) is negligible for a good ball striker. But I really have to flush a fade to get the typical draw distance, so I am not convinced that a fade goes as long as a draw as long as you negotiate the difference in adding loft when hitting a fade.

Rolling and compression.
BerntR does the empirical data you allude to exist? That'd be very interesting.

Horizontal Hinging , Hogans little baseball bat, A.J Bonars closing clubface do seem very real to me, well given decades of field trials. Horizontal Hinging given Homers Alignments being the most precise the others though brilliant are somewhat open to interpretation, respectfully.

By the way does anybody have a copy of the Nick Seitz interview with Ben Hogan , Gold Digest 1980's? Id love to read exactly how he described the rolling face, the little bat.

Not that I know of. It seems like most of the material out there is Trackman based. Very precise on some parameters and pure deduction on others.

The clubface is not a little bat, which implies the face is rotating around the hosel.

Interesting, Mizuno Joe. Hadn't thought of it like that!

Hi Yoda!

I think we'd be astonished by how many people think the clubface acts like the flippers on a pin-ball machine, when in fact, the toe chases the heel of the club around the sweetspot.

That makes sense MJ .....thanks. Effective though Rolling is, its not a little bat or flipper, lever deal per say. Its more about optimal contact. Keeping the point of contact between ball and face intact "as if welded together", no slips or wobbles except for that due to club face loft.

Would you agree? If so what does that do to Hogan's "little bat" or A.J.s "da bat" ? It'd still work but not for the reasons described I guess. Interesting.

the sweet spot on a bat
While we know that the club rolls along the sweet spot plane in golf, I am not aware of a Homer Kelley type inquirey for swinging a bat. It may be similar or it may not- but should we just dismiss it?

Face roll just changes the attitude of the face, I don't see how it could keep contact intact or weld the ball and face.

Ah ha! Now I understand Yoda's reference to "da bat"!
