The internet has never been the best place for communications and I'm certainly not the best at communicating in general, so lets keep going.

You don't have to treat the low point plane line as something under the ground from a visual standpoint. The equivalent line is on the surface of the ground. Its a two dimensional line right next to the target line, but just outside of it. Since your eyes are not in the plane itself but well above it, you can visually treat the low point plane line as a separate line.
The only time the clubhead is concerned with the low point line is at low point. (:doh: what a deep thought. Told you I wasn't a good communicator) You will contact the ball on the target line but the clubhead will continue to the low point line, touch it for an instant and then move back up plane.

Back to topic -

From the top of your swing, mentally draw a straight line from your right index finger to a point on the ground in front of and just outside the center of the ball. Take your karate chop/lag pressure all the way down the line to that spot with quiet hands. The point you select to aim at really depends on the club selection and your hand speed. So experiment with it and move the point backwards or forwards until you locate what is right for you.

It might help if, on the practise tee, a tee peg is put into the ground at this spot as a visual aid.

If the tee peg is obliterated by the swing, then the "aiming point" has been hit.

Cool tip Burner i think i'll try that.

Thanks for all your help Bagger. I think it's one of those things that is easy to understand if explained in person but can be a nightmare on the internet.

Just one quick check. So the visual line you aim at is on the ground. It may or may not be the low point plane line, in fact in most cases (with irons) it won't, it will be further up plane. Is this correct?

Cheers Danny

lagging the hosel
 

Bagger,

I too am trying to swing and have not had much success with the karate chop motion- don't trust it yet. I always want to uncock and roll right from the top. Are you not lagging the hosel when you do the karate chop motion? Just wondering how this works. Have you hit any shanks while practicing?

Thanks for the help!

Even though the hosel and clubface sweet spot are inline that doesn't mean you are lagging the hosel. You are always lagging the sweetspot.

The way this works is two-fold:

As the clubshaft nears its in-line condition with the left arm, the sweetspot of the clubface will automatically rotate much like a clubhead attached to a string.

Secondarily, the straightening of the right elbow will assist in rotating the clubface into impact. It helps provide the paddlewheel motion of the flat left wrist. You can take a "standard" grip and see this for yourself. From a release position, simply straighten the right arm and notice how the clubface closes. For a snap release, you will notice that the right arm straightens much faster during release.

You absolutely have to trust this to automatically happen without manipulation. Take the pressure points in your hands down a direct line to an aiming point in front of the ball. Don't quit on it. Keep it going and keep your hands relaxed throughout.

Start by slowing your hands down and swinging about 50-75% of your current effort.

This is an automatic procedure. There is a non-automatic as well.

Thank you for the help. That makes sense and I am working on making the move automatic- just do not trust it yet!
