What would make a ball hang in the pocket?

[hang-the-9]

Shot down the rail a bit. Ball does not hit a rail, go past the jaw without touching either of the points, hits inside the pocket, and then just hits back and forth between the jaws.

It hits the outside pocket side where the arrow is. I thought once it got past the points, when it hits that inside it should just roll into the hole, not hit back out towards the other side and sit. Is the table sitting out past the coushion here inside the pocket to it kicks it back out?

Glue build up over the lip of the slate, or the liner of cloth was glued to high to the point that it's up over the lip of the slate. Shouldn't be to hard to feel it out and know for sure.

Chances are that the cue ball grazed the rail before the pocket. Sometimes it happens so slightly and so quickly you may think it did not touch the rail when actually it did.
Look at Dr. Dave's high speed video of a ball rattling in the corner pocket and you will see what I mean.

No rail, it's away from the rail the whole time it heads to the pocket and it does not even hit either of the points, goes just a bit past the outside point. There are several pockets at the place I play that are famous for doing this.

I'm not a mechanic but measure the angles of the cushions into the pocket at the corners and post back.

Are you making any contact with the facing? Where on the facing is contact being made? The most pocketable part of the facing is 5/8 away from the point and extends from there to the back of the facing. This was tested repeatedly with jigs, accelerometers and a machine to accurately repeat the stroke. This test was performed for The Science of Pocket Billiards and is based on a standard opening. Any ball stroked between 5/8 and the point is a crap shoot. Pockets with an angle beyond 143 To 145 increase the distance from the point dramatically, which in turn decreases usable area of facing. I hope this is helpful, I am not sure what you were asking.
