Is it Possible to CUT AN OBJECT BALL MORE THAN 90°?

[dr_dave]

I have failed at pocketing rail cut/kick shots at >= 90 degrees but I noticed you added some draw to the inside english. I will try that out.

For the long, extra-steep rail cuts, inside spin helps swerve the CB into the shot angle some (especially with more cue elevation). It also creates drag, which intensifies the effect of the sidespin (see the drag shot resource page).

I was surprised at how fast you hit the cue ball and, still, enough spin-induced throw occurred to pocket object ball. The faster speed was necessary for object ball to reach pocket.

With throw, what is important is the relative speed between the ball surfaces (see throw speed and spin effects). The CB is moving forward fast in one direction, but it is also spinning in the opposite direction faster relative to the cut (hence the throw to the left with clockwise

spin transferred to the OB). The relative sideways speed between the CB and OB surfaces at contact is much slower than you might thing.

Your video packed in several minutes what would take extensive discussions and excessive verbal abuse to learn here.

Agreed. A carefully planned video can be much more effective than online discussion and debate. I'm glad you got something out of it.​

Not sure with 90, but I'm sure I had pocketed balls more than 45.

Long ago the late Nick Vlahos made 90 degree cuts with the cue ball placed one ball to the right of the head spot and the object ball in the center of the table. Saw him do it many times, and this was when he was about 15 years old.

The last shot in the video shows that would not be very difficult with a chalk mark at the ball contact point.

Dr. Dave, an excellant tutorial video. My question is, can snooker balls, being smaller, deflect more than pool balls? I saw some cut shots some years back on a snooker table that were quite amazing.

Dr. Dave, an excellent tutorial video.

Thanks. I'm glad you liked it.

Snooker balls should throw the same amount as pool balls, unless they are cleaned or polished differently. See the videos in the 2nd section here:

This does not make sense to me. The object ball in the center of the table? What pocket is he shooting at?

Wec are lucky to have Dr. Dacve share his info, only LOW IQ People would not appreciate the good Doctor.

Actually, low IQ people are more likely accept what they are told without question. I prefer people who think more critically and say prove It. Doesn't mean they doubt what you say just they prefer some proof.

With throw, what is important is the relative speed between the ball surfaces (see throw speed and spin effects). The CB is moving forward fast in one direction, but it is also spinning in the opposite direction faster relative to the cut (hence the throw to the left with CW spin transfer to the OB).

what is CW?

I would say shot two is more of kick .... You hit the rail first and spin into the obj ball

You couldn't make the shot with outside English like the shot 1

 

[Patrick Johnson]

what is CW?

Clockwise - the direction of OB rotation (viewed from above) when hit with right (counterclockwise) spin on the CB.

Good point, but the extreme-angle rail-cut shots at distance shown later in the video with an effective angle greater than 90° would not be possible with outside spin.

Wow, I’ve known about the rail version of this shot, and about spin induced throw, for many years, but I must say I had no idea it was possible to cut a ball in at 90 degrees from out in the open like that. Nice video, thanks.
Btw, I’m new here but I’ve been subscribed to your YouTube channel for a few years, and I’m familiar with some of your other instructional material as well. Always fantastic stuff. Thank you sir, for all your contributions.

The side pocket. What else? And I don't remember that he ever put chalk on the object ball, though he may have FAIK.

You're welcome. I'm glad you learned something.

Welcome!

You're welcome. I aim to swerve.

What else? The most important. Which side? One side would be much harder.

I think the last shot in my video shows that even the tough side should be possible.

He was shooting from the head spot with the cue ball one balls width to the side of the spot. Do you mean you could cut that shot in either side pocket? The frame at 6:18?
