I used to have a protractor
I was hoping to have them transposed to a pool table diagram. Thanks for the advice
Thanks but I’d like to see balls on a table played into a pocket. I’m really not trying to be difficult, sorry if I appear to be.
a true engineer, i can do this later. im at work
Fractional-Ball Aiming - Dr. Dave Pool Info
Answers to frequently-asked questions about fractional-ball aiming.

Thanks...just what I wanted
I just want to add to make this perfect for practice is cueball position. 15 degree cut cueball should be about 1/4 ball width to ob when practice that cut. 30 degree is half ball cut so cueball should be half ball right from ob. 45 degree cueball should be 3/4 ball width to right from ob position. 60 degree cut is so delicate cut i can´t say exact width from my memory but little more than 45 degree cut.
Then you can shoot always parallel to side rails and learn how these cuts look for. Mirror shots to other corner too. It will reveal if your lining up shot is wrong. I do these a lot.
For any cut shot, the closer the CB and OB are to each other, the less of the OB you'll have to aim at (with the cue ball) to get to the right contact point to pocket the ball.
With Poolmanis’ setup you aim at the same fraction from any distance, because the CB is parallel with and moves toward the ghost ball, not the OB.

Good point, thanks.
An alternative way to do the same thing is to first place the CB on the designated spot and freeze the OB to it in line with the pocket. Then the CB can be placed anywhere on the long string and shot directly along it.

Also. if you shoot shots with really slow speed then you get more collision included throw. Especially slow stun shot. If you aim same way those you miss them slightly too thick. So same cut is not same with all speeds and spin. Practicing this way you will find out that fast. 
this is very good
Isn't that the same thing as Dr. Dave's fractioinal aiming that Pacecar linked?
15 degree cut: Aim center of CB at a point 1/4 ball inside the edge of the OB
30 degree cut: Aim center of CB at the edge of the OB.
45 degree cut: Aim center of CB at a spot that is 1/4 ball beyond the edge of the OB
What is mirroring the shot to the other corner?
1. Those are approximate cut angles for those fractional alignments. Actual = 14.5°, 30° and 48.6°.
2. Poolmanis was describing how to place the CB (beside, not on, the centerline) for maximum accuracy.
It means you can use the same setup to shoot into either far corner.

I guess what I meant to say is as the CB and OB get relatively close together, for a sharper cut, you may not even be able to get to that ghost ball contact point on the OB necessary to make the shot that you could get to if the balls were further apart, on the same line.
