Confessions of a serial flipper. This is how am I attempting to overcome the flipping problem which for ME -- I describe as an early (before P7.5) downward cocking of the wrists which destroys your flying wedge that should be maintained to impact. My flip occurs between P5 and P6.
FIRST I have attempted to read all that I can on the mechanics of the swing and flipping. I recommend 3Jack and The Machinist instruction on their blogs as follows:
Example of hands slowing down and quitting: http://3jack.blogspot.com/2009/09/3jacks-translation-of-tgm-part-6g.html
Example of keeping the hands moving at a constant speed and how acceleration is really created in your swing by the endless belt: http://3jack.blogspot.com/2009/09/3jacks-translation-of-tgm-part-6f.html See also the Machinist blog at http://golfingmachinist.com.au/article.php?id=1
3Jack states: “The hacker who has throwaway slows down those hands and loses that lag pressure in the hands. That causes the clubhead increase in mass and the hands keep slowing down. One major thing to note in the golf swing is that ONCE THAT LAG PRESSURE IS LOST, IT'S GONE, YOU CAN'T GET IT BACK IN THAT PARTICULAR SWING. Furthermore, ONCE YOUR HANDS SLOW DOWN IN THE DOWNSWING, YOU CAN'T SPEED THEM UP IN THAT PARTICULAR SWING.”
Example of geometry of the circle and why the low point is after impact: http://3jack.blogspot.com/2009/09/3jacks-translation-of-tgm-part-5.html and
http://3jack.blogspot.com/2009/09/3jacks-translation-of-tgm-part-6e.html
As 3Jack states: “If you 'flip' the low point will move further back in your stance, but it's tough to figure out where the low point will be. If your left wrist is flat, the low point will always be opposite of the left shoulder.”
The low point of the swing is after impact BUT only if you have not flipped. If you flip prior to P7 then you have lengthened the radius of your swing causing you at best to sweep the ball at impact. Flipping destroys your constant hand velocity and slows the swing AND deprives you of the acceleration at impact.
Know the 3 pressure points of the grip and 1 pressure point between the chest and left arm. Read the Machinist blog: http://golfingmachinist.com.au/article.php?id=66
Know what the FLYING WEDGE is! Read the Machinist blog: http://golfingmachinist.com.au/article.php?id=30
Know what the 4 power accumulators are:

Know whether you are a swinger THUS 423 or a Hitter THUS 4123.
SECOND. Practice drills that I am using:
9 O’clock to 3 O’clock wedge drill (acquired motion drill) with a wedge – Exaggerate -- get your hands all the way to your left thigh before impact Visually – allow yourself to see your hands go by the ball before impact occurs; Audible –allow yourself to hear impact after your hands go by the ball; Kinetically – allow yourself to feel the low point 3 inches after the ball; No divot before the ball.
Same drill with 8 iron off a tee and put tee in ground 3 inches after ball. Make sure divot is after the ball impact. Hit the second tee. Hit the 8 iron as low as possible.
If you are a swinger then hit ¾ iron shots off a tee taking the divot after impact. Concentrate on constant hand speed. For me this means keeping enough pressure at PP#1 (right heel pad on left thumb) so that the hands work as one unit to keep a constant speed but not so much pressure as to stiffen the forearms and you do not want to activate Power accumulator #1 – extension of the right arm – you are practicing 423 power accumulators NOT 4123. IDEALLY Allow your left arm to completely unwind all the way to your left thigh while keeping the flying wedge.
Pleaselet me know what you have found that works for you. Thanks for listening.
