Howdy again,

i understand ( I think ), the concept of the 3 types of hinge actions, vertical(club staying square with a feel of a clockwise/reverse roll), angled(no roll), horizontal(full roll) as brilliantly demonstrated in Yoda's videos.

MY understanding, if correct, is that..assuming i want to play say a horizontal hinge action...from impact, i can imagine a hinge-pin, stuck verically through my left shoulder....and my whole left-arm-flying wedge(and club of course)....is going to turn horizontally around this vertical hinge-pin.....just as a door does, giving the feel of a full roll.

The concept of hinge action is based on aligning the clubface (usually in a hooked position relative to the hands - another reason to monitor the hands) and the plane of the hinge action to control the clubface going through a moving center point of the left shoulder whilst the clubhead travels around it on an orbit on an inclined plane. However it is the left wrist not nessesarily the entire left arm and its vertical association to the plane of the hinge action that controls the clubface. Im not particularly a fan of the use of feels of rolls otherwise we get incorrect interpretation like Ben Doyle, let the mechanics produce feel...

For simplicity all you have to think about to do horizontal hinging you can just keep the left wrist vertical to the ground... get a heavy shopping bag, hold it in the left hand and slowly (to not to make it swing) move from impact to followthrough (both arms straight) - its weight will keep the left wrist vertical to the ground....

However.... in Yoda's video's...he demonstrates this...with only the left hand on the club, swinging the left arm & club & wedge horizontally around, just like a door.... but...heres my problem.....


if i try to do this with BOTH hands on the club, as my lefthand & left arm(parts of my flying wedge assembly obviously) try to hinge horizontally around the vertical hinge-pin that is staked through my left shoulder.... as this moves....since the right hand is also on the club.....the right hand will move around too....and since my right arm is connected to my right hand....the right arm...will move HORIZONTALLY around....and so will my right shoulder. Doing the hinge with left arm only..is a snap....but.....doesnt trying to do that same horizontal-hinge movement with BOTH hands on the club mean that..instead of my body turning correctly around my spine it will be forced to somehow start to turn around the same vertical hinge-pin that im trying to make my left arm -wdge turn around? I cant see how you can have a left-arm-horizontal movement of the left arm(around the vertical pin in the left shoulder) without the left elbow breaking as you try to do it.

Any help gratefully received

Your interpretation of hinge action is still a lil shakey. The concept of horizontal hinging is basically you have 2 hinges - the primary hinge which moves the left arm around in a circle and the secondary hinge which lifts the left arm up and down.

These two hinges can move the left arm anywhere - its got two axis of rotation at 90 degrees to each other. Now if you look at the law of the flail you will see the swivel joint which the represents the left arm or forearm (btw it really doesn't matter what the upper arm geometrically does whether it is turned or rolled) this goes out of line except through the impact interval and when the left wrist is vertical to the plane it produces the same hinge action to control the clubface position and its compression.

The right forearm role is for tracing the plane line and is responcible for lifting the left arm structure up and down (secondary hinge).

For the swinging procedure you drive the primary lever assembly by either using the right shoulder to go downplane tilting the spine (whilst maintaining a stationary head of course)- using the pivot to create a pressure against it where the left arm contacts the chest. It sounds like you have some strange interpretation of the physics of this...

The simple way to do it is just monitor the left hand through the impact interval.....
