Compression?

[John Graham]

I'm hoping this will help me understand Hinge Action/Motion (sorry, as I'm still working on my terminology).

If two players wind up at impact separation with the clubhead, face and shaft in the exact same alignments all at the same speed and hitting the ball in the same spot on the face with every other alignment matching with the only difference being that one player arrived there after a Horizontal Hinge action and other player arrived there after a Vertical Hinge Action.

Which shot has better compression and why?

I think they would be the same.

Great question, and I look forward to hearing the answer...

My first thought was that you can't create the same amount of club-head speed with vertical hinging as you can with horizontal hinging, but I always confuse horizontal hinging with the #3 accumulator... just can't get my head around the difference sometimes, and I know the difference is huge. See ya later, gotta go do a little studying myself, I shouldn't be this far behind!

I have nothing to offer as an answer, but I can join in by asking if compression and ballflight are related? The horizontal hinge action gives longer and lower shots with more roll than the vertical hinge action does, but that doesn't necessary mean that the compression is different? I don't know. But the force applied (if that is the same as compression?) - will behave differently and give different ballflights.
Testing, testing.

The short answer...

Horizontal hinge motion is more efficient, so given similar parameters leading up to impact, when the ball leaves the face horizontal hinge motion will impart more force to the ball than a vertical hinge.

There is a 'leak' of power inherent in a vertical hinge.

They would have the same compression!
True VH allows only manipulation of the loft (layback) HH allows manipulation of the clubface to the left or right (no layback). In other words it would be easy to hit a high soft shot with VH and a low hook with HH.

Im thinking there are factors, club loft for instance. But the compression would be different.

The more loft to the club the more the layback will induce a roll up the face or a roll off the face even for VH. Whereas HH will tend to see the point of contact between ball and face remain together, with "as if welded together" being the ideal.

[BerntR]

Vertical and horizontal hinge both have very good ball compression characteristics.

Keeping the loft of the club out of the equation, the vertical hinge action itself will impose back spin while a horizontal hinge action will impose side spin. We're talking as perfec as it gets here, and then a horizontal hinge will produce a draw. This is layback without closing vs closing without layback.

If we're talking about a human golfer it is very difficult to anticipate that all other alingments can be the same. Dual Horizontal hinge has the largest clubhead to hands speed ratio, while vertical hinge has the smallest. So if the clubhead speed is the same, the vertical hinge will have greater hands speed, and thus a greater effective swing arch and more effective mass-velocity to back up the collision with the ball.

As long as the vertical hinge can keep up with the horizontal - which isn't very long - I guess you will get more ball compression due to the faster hands.

HB, I couldn't agree more.

This is perhaps more in the MacDonald style we need to practice?
