To Dr. Dave: Idea for a video I'd like to see

[DogsPlayingPool]

Good doctor, with the flurry of recent work you and Bob have put out I thought of another one I would really like to understand. That is, what exactly happens during the 9 Ball break that makes the wing ball?

As we all know, when breaking from the rail with about medium speed, the wing ball on the breaking side can be made with frequency, at least with a perfectly tight rack (i.e. Slug Doctor or Magic Rack). But when I look at the 9 Ball rack, the kiss (wing ball and the ball in the next to last row) is not dead at all but far enough up the long rail so that it could not be made by throw alone. Same thing with the 3 ball combination of the one ball, second row ball, and the wing ball. This combo is not dead either.

So I'd really like to know from your viewpoint specifically what goes on during the break that makes the wing ball dead. One of your awesome super-slow mo's with a narrated explanation would be cool.

I have been wondering the same thing for a while now. :thumbup:

+1 This would be cool to understand.

A slow mode would be great. He already has video of it going on the break
maybe he could slow that film down. That would b cool

I did see his normal speed video of the soft break where it talks about making the 1 ball in the side. And actually that's another aspect of the 9 Ball break I'd like to understand, since that carom is far from being "on" either.

But what would really be interesting for both the wing ball in the corner and 1 in the side would be super slow mo with an explanation of the physics of what is happening for these shots to get "on the pocket". There must be some chain reaction of one ball into another or most of the force of the break being to one side of the stack than the other, or some darn thing. :grin-square:

It just seems to me that since it can be made with such reliability, that there must be some identifiable scientific (physics) explanation.

Joe tucker's racking secret dvd discussed this.

 

[The Renfro]

What dgem said... The physics of the 9ball rack wing ball are discussed and demonstrated on Joe Tucker's video...

The making 1ball physics would be cool because you could discuss the cut angle on the 1ball and discuss the use of side spin on the break. I know everyone thinks you break with center ball and adjust the hit but a lot of pros use side spin to help park the rock. When you see the rock spinning in place it wasn't center ball and an off-center impact that did that.

I don't recall the what and why of the wing ball in JT's RS, just the how. So can you briefly explain what and why it happens?

Thanks.

Thanks.

Joe does a very nice job of explaining what to look for in the rack, why it acts the way it does, where to break from for desired results (making the wing ball), etc. You will be happy with the dvd.

Agreed.

Tom and I also cover some basic racking strategy principles here:

NV B.89 - 9-ball racking strategy, from VEPS V​

Regardless, the next time I do a filming session, I'll break some tight 9-ball racks with the high-speed camera so people can see the lead-ball and wing-ball action (and how it changes with different variables) more clearly.

Dave

TY DR Dave. It is appreciated

Thanks Dr. Dave! I think this would be really cool to see in slow-mo.
I'll donate a Slug-Doctor Tight Rack (<---- shameless plug ) to the cause if you're interested in trying it out. Let me know via PM.

Best Regards,

Thanks Dave! This is why you are the AZB family doctor. :grin:

 

[PaulieB]

As long as we are making requests and you are taking out the high speed camera ...

Could you go to the local strip club and take a high speed video of a DD stripper doing a hard break? I will let your imagination figure out which rack I want you to be filming.

All I can imagine is you want me to focus on the mounted elk head on the wall as the hard break occurs to see if the antlers shake any.

Is that what you had in mind? :grin-square: :rotflmao1:

PS: I do have some stupid human tricks on my general high-speed video website, but none of them are X-rated (... sorry). Here's the website:

Enjoy!

I was enjoying the new videos until I got to the slow mo "Hurl caused by drinking too much milk" ... Ick.
