Parallel Shift Banking System

Hey everybody -

For those of you who have taken notice that I love banks and have questioned whether they are luck or skill, I'd like to share some info about me.



When I first started to bank shots accurately - this is the system I used.

Find the natural angle, in this case from the 2nd diamond to the first, then parallel shift that through the OB. Then find the midway point between those two lines which still works out for those of you who use the system with numbers (like shooting from 24 to 12 sends you to side pocket of zero).

Anyway - the first red line is the natural line.
The second is the parallel shift.
The blue line is the midway point between the two - and the rail contact point to make the bank on the two.

Now, I no longer need this system except to quickly check where I should be hitting the ball - nowadays I tend to bank by using English and speed to adjust angles.

This is how I started making my bank shots and it's a very good system to use if you want to practice banks.
 
Does that really find the correct line? I don't see how it would, although I'm sure it's close.
 
You have taken the angle off the left edge of the cb and the center of the ob. Why? Have never seen this system before but look like it works but just wonder why the first angle is not taken off the center of the cb? Thanks.
 
When you think about it - it actually makes sense.

To make the bank - you've got to have the same angle into the rail as off the rail. The natural lines obviously work - so to keep that angle consistent, when you move 1 inch on the rail farthest from you, you've got to move two inches on the rail closest to you (looking at the diagram).

When you parallel shift, then find the midpoint between them, you're doing just that.

In this case, the natural line is from 20 to 10. The parallel shift looks like 22.5 to 12.5. The midpoint between them is 1.25 segments right (from the natural line) on the top rail, and 2.5 segments right (from the natural line) on the bottom rail. So, you're still creating the same rebound angle.

The first angle is taken to the left (or right) of the OB (never the CB) because it's a guaranteed line that works - and it's best to find the guaranteed line closest to the OB.

The first line I showed has nothing to do with the CB at all - it just so happened that the CB was there lol. It would be no different if the CB was hanging in lower right pocket.

Also - we don't use the CB at all in finding banks because the OB is the one were concerned with. I'll show another example.



The same thing works here - you find the natural line closest to the OB without even worrying where the CB is.

EDIT: The second white line into the side pocket should be off the rail contact point.
 
banking is mostly about english/spin for me. yes I use the diamonds for visualization, but to adjust for accuracy and positioning on next ball, I rely much on spin
 
Very interesting, Thanks.

Can you show more examples, special when object ball is near to short rail?

Did the second/parallel line should go only through the middle of the object ball?

What speed or English is better for those bank shots?

when you say the natural line, the natural line to what?

anyway, not trying to discredit the O, im sure it works/worked for him but. i play this horible low level player from time to time "he just likes the challenge (lol) i guess" who im sure in his head thinks hes going to beat me one day, but the one thing that he absolutely kills 'KLLS ME WTH" me with is banks, and this is what hes uses, but just the shift and not the first midpoint part.

When he says natural line, I think he means track line. As in diamond 2 matches to diamond 1. Diamond 3 tracks to 1.5....etc. As for another posted question, it depends on the table speed and cushion rebound. But I find pocket speed works best. Any harder and the banks come up short.
 
Good simple system, it does work.
On the second shot one has to remember the english effect on the OB by the way it is hit with the CB, and adjust speed/english a bit.

Three things affect a bank shot: Contact point on the object bank, how hard you hit it, and the English applied. This system works as long as you don't apply English or hit the shot harder.

Also when the object ball is close to the rail (within one to two ball lengths) it can affect the rebound angle by making it hit slightly shorter. I usually help it with a slight bit of English when that's the case.
 
There are so many variables in a bank shot, but your method is a good base line.

Other variables, including what Scott posted.
Humidity or dampness of table
How clean the balls are
Speed of bank
English on Horizontal axis
Balls come off differently from top, to stun to draw
Type of cushion.. (Diamond tables bank way shorter than a typical GC)

I'm sure I missed a few but those came to mind quickly. The best thing I learned was to stay near center whenever possible and that more english does not mean more turn when banking. Bank pool is my favorite game and has been for many years. It's the purest game IMHO. YMMV

There are many "systems" that offer good baselines for different types of kicks and banks. In some situations, they work very well without adjustments; but in most situations, they require intuitive corrections.

FYI to those interested, all bank and kick shot effects that require aiming adjustment are summarized and demonstrated here:

That's the issue with any "system", be it banking, aiming, etc..

It depends on several variables to be constant. You need a perfect stroke, you need the angles to be just so, meaning no odd stuff with the rails, no spin needed and so on. It's good to learn with systems, once you can bank with them, you will hardly use them again unless the table setup just happens to be exactly right.
 
I guess I don't understand your system. It appears to me as if you are taking multiple unnecessary steps to use the diamond system. In both pictures you are lined up about from 2.5 diamonds to 1.25 diamonds.

If you use just the diamond system in his illustration (line one) you miss the shot...

Yes, line 1 misses the shot because if you bank the 2 at the first diamond as "line 1" shows then you're banking the 2 ball from 2.5 diamonds to 1 diamond. His system "works" but it's adding steps to the diamond system. If you line up from 2.5 diamonds to 1.25 diamonds with the object (2 ball in this case) ball between them it's the diamond system.
