Right arm motion
 

Would it be true to say that the right hand, right elbow and right shoulder should all operate in the same vertical plane throughout the stroke? That is, if you hung a door from your right shoulder (or right side running through your shoulder), that your right hand and elbow would stay on it through the stroke?

Have been playing round with this idea recently and it makes some sense to me. Illuminates the right forearm takeaway etc. Try this - hook a club under your right arm and then grab the head of the club like it was the handle of another club (head should point down towards the ground - upside down to usual). Push the club into your right side with your right elbow. Try taking the club to the top and then back to impact maintaining the push against your right side. Feels pretty good to me. Now try (at any point) releasing the club from your right side by letting your elbow get away from the club - seems wrong to me - hence the quesiton above: Would it be true to say that the right hand, right elbow and right shoulder should all operate in the same vertical plane throughout the stroke?

Look at Sean O'hairs swing on golftips magazine. Doing this drill feels like he looks on the downswing.

Sounds like a paddlewheel motion for a horizontal hinge.
