Tip to cloth...:smile:
The usual way that people demonstrate different amounts of side spin is to shoot straight into a rail and see how much to the left or right the ball goes (measured in angle or diamonds).
How much follow or draw you get you can see simply by shooting a full draw or follow shot on a nearby ball.
It is usually best to stick with what happens on the table and do your measurements in diamonds.
As for whether detailed info about the physics of the situation is worth anything, I think in this case it's mostly useful to tell you what not to do. Don't fret over whether a loose or tight grip might give you more action, because in themselves they do nothing for the shot. I suggest that you should use the grip that gives you the most consistency.
Lots of players obsess about getting more spin and hope a new tip or a new shaft or a new grip or a new placement of their back foot is going to help them. Most players who get only paltry spin fail because they do not hit far enough from center.

Hi Bob, sorry for digging up this old post lol, but this effective weight of the cue is constantly bugging me. I read all your and Dr.Dave's comments/articles in this post, and what I don't understand is, what is the criterion for determining if the weight of the hand is involved in the impact or not? How do we know that the normal grip adds 1% of effective weight to the cue? What is the reasoning behind this? So far my own explanation is that the palm is very flexible, so during the tip-ball impact, the cue slides on the palm as if there is no hand: the skin effectively serves as a lubricant between the hand and the cue. Therefore the hand doesn't participate in the collision at all (in practical sense). Does my explanation make sense? Or did I misunderstand something?The usual way that people demonstrate different amounts of side spin is to shoot straight into a rail and see how much to the left or right the ball goes (measured in angle or diamonds).

If you study the speed vs. time curve of the cue stick, you can derive the spring constants for both tip-ball contact and the hand-cue contact. That leads to the effective mass increase of the cue stick due to the contribution of the hand.,,, what is the criterion for determining if the weight of the hand is involved in the impact or not?

Thank you for the quick reply. Appreciate it.If you study the speed vs. time curve of the cue stick, you can derive the spring constants for both tip-ball contact and the hand-cue contact. That leads to the effective mass increase of the cue stick due to the contribution of the hand.
I think the video link and explanations on the grip tightness effects resource page explain it fairly well. FYI, I expanded the description a little today. As Bob points out, because the grip hand flesh is so much more flexible than the tip, the CB is gone before the grip feels anything from the CB impact, so it can't contribute much to the mass of the cue during the collision.
Everyone seems to keep referring to letting the cue slide forward (throwing the cue) as a "slip stroke"...I've always considered a slip stroke to be holding the cue slightly forward of dead hang, then slipping the grip hand back a couple of inches on the back swing, forcing your cue to follow through the contact. Many if not most of the top Straight Pool players of old did it, notably Cisero Murphy, the Meat Man, even Willie Mosconi (sometimes). Watch Cisero at the 9:07 mark...
I believe this also. It’s not the loose grip that creates more “action’, but the loose wrist. You can’t have a loose wrist with a tight grip.The tightness of the grip itself doesn't change CB action, but it could affect how your arm and wrist muscles work to produce stroke speed.

Here's a good look.Yes, the original slipstroke referred to the hand slipping back on the final back stroke. Purely in an effort to end the confusion a handful of people on this forum agreed to call the release of the cue to let it slide forward just before contact with the cue ball a stroke slip to differentiate between the two completely different moves. Most of the people in those old discussions are gone now but I think the terminology should remain to minimize confusion. Releasing the cue on final delivery is not a slip stroke.
Hard to see Cisero's slip, Jimmy Moore is another almost full time slip stroke user with some cleaner video. The old players usually had a handful of strokes in their arsenal and would use whichever was best for a particular shot. I had footage of Willie using a slip stroke in practice for no particular reason so obviously practicing the shot. He often used a tiny slip, difficult to see. However, he also used a pretty big slip sometimes. The old players were versatile and saw no reason why one stroke should have to fit all occasions.
I try to practice a slip stroke now and then simply because done well it may be the prettiest stroke in pool. I had video of an old master of the slip stroke that made it seem that he had an extra joint between elbow and wrist or that his forearm was made of rubber! I was playing somebodcheap and was using the slip stroke. After twenty minutes or so he couldn't help himself, "What are you doing?"
One place the slip stroke really shines is the shots with the cue ball on the rail. The shot feels much more like a typical shot when you add a slip.
