The Line of Compression

[EdZ]

In talking about applying FORCE in the swing, and where that force is directed, it is important to keep in mind the goal - sustaining the line of compression.

With that in mind, I'd like to hear how people view the line of compression.

In a nutshell - drive the nail through that ball

And so I pose the question, what is the 'ideal' orientation of the 'nail' that you are driving through the ball? (for a given shot)

And WHY is that the ideal position?

How does that orientation change, if at all, between clubs or desired ball flight?

In a nutshell, no, wrong.
Where the clubface is applied on the ball is maybe more important then your nuts.
And only horizontal hinge action can have the perfect compression. The others don't and must be compensated for.

I understood "driving the nail through the ball" as hand positioning. I try and drive the ball into the ground, this creates max compression.

But only on the sweet spot of the clubface so the ball does not slide up and off the clubface. That is why horizontal hinging gives max compression and angled hinging by its nature allows the ball to slide off producing its fade. A hitters muscle strength over comes and compression leakage to prevent distance loss.

EdZ.. 2-C-1 #2A,B,C gives a rather clear indication with the LOC line. It starts at the center of contact during impact and goes directly on a cord with the center of contact at the point of seperation through the Arc of Approach AND the Arc of Attack. It's drawing a linear cord through the arc of the impact interval. Just remember, the Resultant force will be at exactly the mean of the angle between the line of compression and the Rebound Direction created by the bulging (outward flow) effect of the ball.

njmp - maybe more important than YOUR nuts, not mine.

As far as your 'no, wrong' answer - are you driving your force to 'a point' on the ball? Do you continue to direct force in a straight line?

A feel vs. real problem perhaps.

"Sustaining the line of compression": MAINTAIN the relationship between the "contact/impact point (between the clubface and the ball)" and the "clubhead path" during impact (from initial contact to deformation to reformation and prior to separation), I imagine.

Spin or "Leakage" will be introduced to the ball, unless they are PREFECTLY "IN-LINE" during that process.
