Can you transfer side spin to an OB?

That multiple rail thing stumps a lot of people, don't feel bad. If I lived closer, I would show and explain what is going on when a CB hits and OB balls. Very basic really.
lol. I have played for a living for ten years, and I guess I am easily "stumped". Thanks for your kind offer, but I would prefer to just play anybody that truly thinks that. 'Cause none of them can win

Do a video with the transfer... I would like to see it done. Couple things you have to do though... have OB away from rail and get it to travel in a straight line showing the spin on the OB before hitting a rail. Love to see it.
Videos that have to do with physics are always going to be open to interpretation. You are obviously too enamored with the idea that is impossible, and therefore not going to either listen to reason or look at any videos without rose colored glasses. I understand, but am therefore not too hyped about making any videos. You are perfectly entitled to your opinion, I would just like to play if you are ever within a couple of hundred miles. I am actually more interested in making money than in proving any points, especially when it is a fairly well known effect.
Well, lets make some money. Post a video! $100 bucks for one shot. Let me see this done! I will even put $200 to your $100

If there is throw, there is spin transfer ... they are both caused by the same friction force. Throw and spin transfer are maximum with a slow stun shot at about 50% English (not with maximum English). There is spin transfer in your video ... that's why the stripe has a slight wobble. The amount is small, but it does affect the rebound angle off the rail. FYI, much more info, resources, and video demos (with explanations) can be found here:

That is like saying that if you cannot hit the cueball into the same place, and have it hit the side rail before the first diamond, then you didn't spin it. That is LAUGHABLE. how about the same shot, and just have the OB hit one of the two bottom balls? That proves it, well beyond a reasonable doubt. But I have a feeling that wouldn't be proof enough for someone such as yourself. I would even go out on a limb and say that you would be dead set against it. So, how right am I? 100%, or just 99%?
do you have any video of a OB maintaining that spin for even one complete revolution about the vertical axis?
This thread was prompted by another in which another poster maintains that the OB spins significantly enough change the OB direction off of a cushion the same way one can with a cue ball.
and I say no. that cannot happen and I believe both of my videos show that quite clearly.
you can change the angle in with throw but you cannot change the angle out with spin.

This isn't transfer. The CB is hitting off center same as a cue tip. A cue tip isn't spinning with it contacts the CB and yet side is applied. Same thing happens to OB. You post videos here... try this. take two shafts and place them together. at the tip end put OB stripe up. at joint end put another stripe up. put something along side the shafts so they don't move. hit the joint end ball into the tip end using your max transfer speed/spin. make sure the ball is going straight into the rail. I bet it comes straight back with no side transfered.

I would like to see the transfer going to the Ob that will change the game. Make it miss the balls. BET? I will do a video!
Lol, I figured as much. Good luck trying to prove your opinions. I think it is best to leave this thread alone. I doubt anyone will have their mind changed, regardless of proof. Have a nice night!
I'm not exactly sure what you mean here, but the following videos show how a striped ball can sometimes be misleading, when it comes to visualizing spin:
HSV B.10 - MOFUDAT stroke drill follow and draw effects
NV B.10 - Drag spin loss and English persistence
NV B.10 - Drag spin loss and English persistence
I would agree with this, because spin transfer is critical to making certain bank shots.
This statement is problematic because only a small amount of spin can be transferred to an OB.
I disagree. For example, see all of the variations on the shot here:

You can and it can be easily proved with Dr. Dave's transferred spin bank, rearranged a little so its lesson is more obvious. I can make this test shot and so can you.

it is because of the contact point on the OB. Someone try this. Put 2 shafts one on each side of the balls. I could only show one full cue. Once you have a shaft on each side that is braced not to move. Place siding on the OB. It will never happen. It will come straight back between those balls 100% of time. Someone try it rather than guessing! I'm not!

The purpose of the blocking ball on the rail is to show that the OB can only go straight into the rail without any bank angle. If the OB goes straight into the rail without any bank angle, then only sidespin on the OB can make it rebound at an angle.
The purpose of the slight cut angle on the CB is to eliminate collision induced sidespin so that any sidespin transferred to the OB must be from sidespin on the CB.
I don't know if you understand it, but if you or I or anybody can make this shot as it's set up, that proves that significant sidespin is transferred to the OB. Try it - pocket speed with 1/2 maximum outside sidespin.

Shots like this come to mind. And pretty much any shot from "banks that dont go, but do". Without the transfer of spin, they dont go.
without a table in front of me, I may have these setup slightly wrong, but its 1am...
We might as well be talking about, "who believes in aliens".

that is what I would call spin induced throw
the ball is "thrown" offline initially by the english and the collision.
and then takes the new off center trajectory to the end rail resulting in an off center rebound..
it didn't spin to the rail and come back at a new angle .. it was just knocked offline by the initial collision rolled to the rail and came back in response to that angle.
removing one wood runner just added deflection and swerve to the equation resulting in a more pronounced effect as you are no longer controlling the contact point as you did with the second piece of wood..
:grin-square: but what do I know I am just a geek with a pool table LOL
