While on the face, only path influences ball even though the face is rotating while the ball is on it and the ball's centerlined has moved relative to both the angle of approach and arc of approach as depicted in 2-C-1#3 and this has no effect. Then all of a sudden, the ball decides to stop listening to the path and come off the face at practically right angles.

Some smart ball.
Do you agree that "practically at right angles" means something similar to D plane?

Where do you think Homer was wrong? Do you think that the ball doesn't stick during the impact interval? That it rolls on the face? Or something else?

In the 7. edition P.23 it unfortunately doesn't say "practically" any more, but "properly".

"Properly right angles"?

Yes, indeed. Surely a misprint.

"Properly" is a very good choice of words. It means "as it should". It means that the ball leaving the Clubface at Right Angles is the "Proper" way it should leave the Clubface. It's in reference to using Hinging as a means of determining that the Ball will leave at Right Angles to the Clubface. "Properly at Right Angles".

Well - what do you know!
Maybe not a misprint after all. Is properly better than practically since they changed it in the 7. edition?

I already know that the Ball should leave at right angles unless I want otherwise and I know how to make it happen. So, it doesn't matter to me either way. But I do like the word "Proper". It is the "Proper way".........to leave at Right Angles...

AirAir, I think you should understand something. Hinging is the easy part. Not disturbing the Sweetspot Orbit is the Hard Thing. That's what TGM will teach you. And you'll learn that you need a "Flat Left Wrist" to learn how not to disturb the Orbit. If you can get a Flat Left Wrist through Impact, everything else will almost fall in place.

The Clubhead, with a Driver, and the Ball Played back 1 inch behind Low-Point, will travel downwards 1/50th of an inch and outward even less before ball separation. That's how critical it is. 1/50th of an inch. That's the difference between full compression or not. Even with a Putt. You need Hinge Action even with a Putt to gain compression.

It's technique that allows the perfect Orbit of the Sweetspot.

Another good reason to stay with the 6th!

Practically, at right angles is excellent. I wish I had read the book many years ago and it is right in line with all modern ball flight theory. Especially, since the golf balls have become more solid.

I think Homer is incorrect about how a perfectly straight shot is created. I think it is more logical to consider the path of the club during the impact interval as a tangent instead of a cord.

I think that the ball does not get carried down and to the right during the interval. Otherwise the implications would be inconsistent with practically at right angles. It would also suggest that a ball resting on the ground is getting rammed into the ground some amount.

I agree the collision is so violent, as has been expressed here by many, to think that the ball simply does nothing but get carried from one place to another without anything else happening but compression seems illogical.

John I'm typing on my iPhone which is a pain so I won't answer in full , but to address the first things first........ Homer didn't suggest the "path " of the club was a chord to the circle. The circumference it self is the path. It's an arc .

So the clubbead prior to it's low point is going down and out given some degree of inclination to the plane of the circle.
