Aligning the Clubface
 

This post is problematic for me.

..............

The True Swinger allows Centrifugal Force to align for Impact all three Functions of the Club, i.e., the Clubhead, the Clubshaft and the Clubface.

Something I am missing in the physics, club, machine or in my in interpretation. Suspect this aligning is CF reacting to something I have not accounted for. Gravity? Shaft is a snake?

Bumpy consider the difference between the farmers flail and the golfers flail .....

I am still missing a step somewhere
 

:scratch:

I do not see how 2-k gets to a square clubface for a true swinger.

Easy answer - however not one that is quickly answered. Possibly the information below will help you - since I'm on perma hold with Cox Cable this morning.

Let's talk in terms of the "pure" "simple" theory - "outside" of any particular practical golfing example - just to understand the basic principle at play.

First let's clarify the concept "CF aligning". The broader principle is that it could be any straight line force through the longitudinal center of mass of the golf club. So similar to just a golf club swinging in a circle with the pull straight out through the longitudinal center of mass i.e. sweetspot. Let's look at an example that you can see. Take a sand wedge and a 5 iron and hold each lightly at the grip end with thumb and index finger - shaft hanging down towards the ground - that straight line force - gravity in this situation- pulls through the center of mass and aligns each club. The sand wedge leading edge is more closed than the five iron because of the construction of the clubface is different (wider)i.e. more mass behind the leading edge. Likewise, rotating these clubs in a circle would automatically align their club faces - differently but consistently. So you could rely on that principle to consistently align your clubface.

If there wasn't other issues at play as in a human swinging a golf club - for instance if you just had a golf club swinging around a centered rotating pole - attached by a rope say and moving fast enough where the shaft was parallel to the ground - then based on the way they construct golf clubs - you would always have the face closed to the motion of the clubhead at any time and therefore if hitting a ball - you would always produce a draw shot.

This issue of CF aligning the clubface relates to Homer's "Hookface" definition.

It should be noted that Ben Doyle's use of the term "Aiming Point" has no relation to the Aiming Point concept in the Golfing Machine. Not that his point potentially doesn't have relevance or practical implications or useage. The problem arises for people learning the book, seeing the "1st" authorized instructor - using a term from the book in a completely different way and context than the one described in the book. Personally I'd be much more careful in using the terms - if I knew that you read a instructional book on how to drive a car I wouldn't tell you to put the key in the ignition if I meant put the key in the trunk lock to open the trunk.

That is why I restricted use of BD to a time frame 1 to 1:10 (edit that to 1:02 to 1:08.5). That is the point in release where cf uses the golfers flail to get #2 then #3 going.

Regarding the highlighted part of your post. Let's say the CG offset produces a 5 degree closure of the leading edge. Using the plane of motion as a zero reference the leading edge will be 5* or 95* closed ?

Nothing directed at you HB - it was more of a side comment outside the context of this thread.
I though I would clarify - as I think it could come across differently without this clarification.

I think I understand your question but I'm not 100% sure.
See if this answers it.

Using a golf example - say we take the direction of the clubhead movement at lowpoint. Let's call that line the target line. The leading edge is perpendicular to that target line if it is "square" to the target line, or 90 degrees. If the face was 5 degrees open let's call that 85 degrees and if the face is 5 degrees closed we'll call that 95 degrees to the target line.

So 5 degrees closed of square and 95 degrees closed in relation to the target line.

Let me know if I understood your question properly and if that answered your question.

Outside of your question I would say roughly - closures due to clubhead/face construction in relation to square based on the line of pull through the longitudinal center of gravity would be:
1) Greater as you move towards the wedges and less as you move toward your 2 iron.
2) The leading edge would be up to 20 degrees left of the longitudinal center of gravit for the wedge. That's not a correct answer - haven't measured it. might only be 10 or 8 or something. I'm sure we could measure it while we are hanging the clubs with our thumb and index finger.
