If I've understood it correctly to hit a ball straight with let's say a 6-iron, given a standard vertical shaft plane of 60º if I hit down on it 5º, I'll have to swing just about 2.5º left and the face at separation has to be square to the ball target line(that's a bit I'm not 100% sure about, please correct me if I'm wrong)

What exactly are the numbers Trackmen users are seeing for the slightest of fades and draws.

I'm assuming that with a fade the A of A might be a fraction steeper which would require a slightly larger shift of the horizontal plane to the left, but where is the face aiming? With a 6-iron would 6º down, 3º left and the face 1.5º degrees open to the path but 1.5º closed to to target be workable numbers to hit the ball to the target?

With a draw, I'm assuming the A of A would be slightly shallower, let's say 3º down, this is where I get confused. Does 3º down mean the path goes 1.5º out more or less so if I have the face 0.75º closed to the path but 0.75º open to the target that would be workable?

Any help would be much appreciated.

Thanks,

James

Dont assume at all that the A^A would be steeper with a fade, it definately isnt always. With a draw, yes, you would like to control the down because it would skew the path more in to out.

If memory serves me correctly, generally, with center contact, a face about half the path will curve to the target and land there.

Spin Axis: The difference between clubface and path

1. For an Iron, Spin Axis will be tilted 2 times the difference between path and face. (Driver 4 times the difference)
2. For one degree tilt in spin axis , the ball will move 0.7% of the total carry.

Example:
Baby Draw (or fade) by changing club face

1. Zero your club path : Club path will be affetcted by AA, HSP and VSP.
(VSP = 60; AA -4; HSP -2 will result in club path = 0)

2. Club face at impact = -1 (closed)

Result

Spin Axis = -2

Carry Distance = 175 yds

Side from target = 175 * 0.007 * -2 = -2.45 yds (Left)

Similarly a open club face will produce a fade

Alternate Method: A golfer can change either AA, VSP or HSP or all of them to change the club path away from the target and maintain the club face at target to impart desired tilt in the spin axis and the ball will curve accordingly.

Fade: club path = -1 and club face = 0
Draw: Club path = 1 and club face = 0

Experiment and choose your own method. For me changing the HSP by setup changes (open or closed) works well. :D

Thanks for that information. When you say "Clubface at impact = -1º (closed)" Do you mean closed to the target?
