The Key to Accurate Bank Shots Using the Wear Line

Often a player needs to make an accurate bank shot to get shape on other object balls. Everyone knows geometric principle of a bank shot. Equal angles into the rail and off the rail. But very few pool players realize that a ball behaves as if it were reflecting off the "wear line" in front of the cushion where multiple ball strikes have "snubbed" a ball into the felt table top leaving an indentation, and not off the cushion itself.

The Key to Accurate Bank Shots Using the Wear Line

The key to making ACCURATE bank shots is to realize that a billiard ball behaves as if it is rebounding NOT from the cushion edge, but rather, as if it were rebounding off the WEAR LINE in front of a cushion.

This wear line is almost 1 ball radius out from cushion where multiple ball snubs have left trail of indentations.

Any geometric measure of dropping perpendiculars and crossing pool sticks must take this reality into account to achieve a high degree of accuracy on bank shots. It is why even professional pool players will often miss their object ball completely when left with a safety kick shot.

If the inbound and rebound angles are measured from banks edge (which is the wrong way to do it), an error of 1 ball radius is introduced. On the rebound, this error doubles where now its 2 ball radii, or, a complete ball diameter. No wonder they miss.

Once you think about how you align your aim for the cue ball onto an object ball in order to pocket a ball, you must realize the momentum transfer from cue ball to the object ball goes straight through centers.

The SPAD Group has an optical device called the BankStop which is based on this principle to train for kick shots How good is it? Well, with it, an average-Joe pool player can pocket 3 out of 4 kick shots.
