Second to that, probably what horizontal hinge motion really is (that it is the left wrist relative to the left shoulder hinge pin). Easy to show on a horizontal plane, confusing to many on the angled plane.
Third, loading as it relates to the flying wedges.

As a newcomer to TGM, I would love to see you, and other senior members, open up individual threads on those listed topics, and also topics like the endless belt. I would appreciate any insightful input to those individual threads that increases my understanding of all those topics.
I dont get the hooked face irons thing and the implications there of.
Word . . . consider the old weight on a string deal . . . weight is spinning round and round . . . then it flys off. Physics has it flying off at 90 degrees to the radius. So imagine if you tilted the axis of the whirling string so it was spinning around on an inclined plane. It still would leave at 90 degrees to the radius which would be OUT TO THE RIGHT.
The concept is the same in golf. The clubhead is the weight on the string. The force that you are generating would be at right angles to the radius. So anything back of lowpoint the force is OUT TO THE RIGHT. So design hook face into the club to DIVERT the force so you can hit the ball down the target line and not out to right field. Notice the longer the iron the less hook face . . the are designed to be played closer to low point.
Hope that makes sense . . . any correction would be good from any of the HEAVIES lurking.

OK Maybe this wont be a quickie after all. Sorry.
I am with you on the shorter irons being played further back of low point. I can see how being further back of low point they therefore have more out and down after impact. I get how the weight that flies off the string prior to low point flies to the right of low point, but dont get the relevance to a golf shot.
I've been looking at my irons for years now and dont see a hooked face. Where is it? Is it something to do with progressive shaft lean?
This is an oversimplication but give it a try: Replace your Clubhead with a tennis racket head (on the end of your Clubshaft). At Impact, the tennis racket head would drive the ball both Down and Out into the ground and to the right as Bucket explained. Note: the Sweetspot of the tennis racket is in line with the Clubshaft and the racket has no Loft. The Force is always Down and Out at Right Angles to the Radius. The Club manufactures would then have to add loft to the racket face, which would make it hit the ball further right (rotate the racket face clockwise in your hand to add loft). The manufacture now creates a Lie Angle by taking the Sweetspot of the racket Head out of line with the handle by giving it hookface. Now take you old Club, without the tennis racket on it, and hold the shaft parallel to the ground. Look at the face. Which direction would the ball go if the Plane of Motion were parallel to the ground? It is not going to the right.
Your job, if you decide to accept it, is to drive the Clubhead both Down and Out from Impact to Low Point, not toward the Target. The design of the Clubhead and Face is to divert that Down and Out Force to an on Target Force (Reference 2-D-0, first paragraph on page 24). You do your job and let the Club do its job. Don't do the Clubs job! Let it do what it is designed to do.
The amount of hook face varies from club to club. Mathew did an explanation on the intersection of Planes that goes into more detail than me.
Do a search and you should be able to find it.
Didnt want to use my Mizunos so I just cut the head off my wifes 5 iron and her tennis racquet too. Im sticking them together like a giant tennis racquet.
OK I get what your saying. Nice. OK. Out and down.
Hey this sort of relates to the dilemma I face when I have a say a pitching wedge from a severe side hill slope with ball way above feet. I grip down and adjust the sole to a more horizontal plane than the slope, so its still "loft" not "left" and then take more club given the chocking down and aim to the right to accommodate any remaining "left" , swing out and
Oh, oh her she comes,crap, oh she's pissed!. Gotta go.
OK Im back and apparently I now have an infinite amount of time to devote to golf. Ive added loft, Im just about to add a lie angle to the head, will this alone give it a hook face? The steeper the lie angle the more the hooked face?
Im close to enlightenment but not quite there. Is shaft lean a factor?
Keep it coming Im close, I've got lots of time and am all ears.

This is my understanding of how hookface works. Clubhead COG is not in same plane as the face of the clubhead.
If that is correct then what is happening with the new drivers where COG is forever being moved further back away from clubface?

Required reading for golfing neophytes and all duped lemmings! I proved this with pvc pipe and golf balls! Place the ball in the pvc pipe and time (if you can) a straight away release. Of course there is no hook face to divert, it is amazing how often able bodied teens leave the ball in the pipe! We start from top!
Most people think that the only hooked faces are on their super-duper anti-slice drivers! Square is NOT square folks!

Im still not all the way there on this one. Assuming the golf ball is struck back of low point with say a baseball bat, it will go right. The golf club is therefore manufactured with a built in amount of shaft lean and an appropriate amount of bounce given its shaft lean and a square to the target face? Is this right? Is this what is meant by hook faced short irons?
