The player must then pocket a numbered ball, or cause the cue ball or any numbered ball to contact a rail. In this game the object is to pocket the 9 ball after the cue ball first makes contact with the lowest-numbered ball on the table. However, you can easily differentiate them by looking at the table and the ball’s numbers. The numbers on the front of the practice locks indicate the keying codes, from the front-most pin stack to the rear-most. LAB is a lock pin and locksmith tool manufacturer. A variety of picking tools are available through most locksmith supply distributors. Most of the esoteric pick designs in the huge, overpriced sets you see on the web and from locksmith suppliers are useless, and eventually end up being discarded in favor of the basic hooks. There is a more detailed discussion of configuring training locks at the end of this document. In the lab there is a collection of "training locks," mounted on boards, for practice. In the lab you'll find a collection of small (12 inch by 18 inch) lock boards, each containing six specially pinned locks with a given keyway.

United States and Canada, played with a white cue ball and 15 consecutively numbered coloured balls on a rectangular table with six pockets (one at each corner and one at the midpoints of both longer sides). Pockets on the pocket billiards table are wider than those on the English billiards and snooker tables. Hand-stitched leather shields and top-quality long-lasting net pockets. The height (or cut depth) of a key under each pin stack position is called its bitting; the bitting of a key is the "secret" needed to open a lock. While this might have gotten the lock open, you just as easily might have pushed the cut past the shear line entirely, preventing the lock from opening altogether. If this pin stack is slowly pushed up with torque applied to the plug, eventually its cut will reach the shear line and the plug will turn a bit more. Raking, in contrast, is a class of picking techniques in which several pin stack may be set at the shear line simultaneously.

The top pin of the most misaligned pin stack becomes "pinched" at the shear line between the plug and the shell. Several positions are possible; here a vertically-oriented torque tool is used at the top of the keyway. The anchors are treated as separate balks, and scoring within them is similarly restricted. In particular note that because the pins are slightly out of alignment, as the plug is turned gently, only the pin stack that is most out of alignment actually prevents further rotation. Keep practicing with the two pin lock, trying to lighten your touch as you do, and making sure you consistently can pick the pins one at a time. Spend more time on this exercise than you think you need to; most people never learn to properly apply the light touch needed to pick better quality locks. Develop a light touch. First, apply light torque (as you practiced in the previous exercises) to the two pin cylinder and gently feel each pin. Figure 1. A pin tumbler lock cylinder. There is no reason to believe that the software used in electronc lock systems is any less subject to bugs, vulnerabilities and protocol failures than the typical (buggy) software used in other applications of similar complexity.

There is a tradeoff, of course, since a longer handle may be difficult to maneuver around obstacles. When you feel confident visualizing and using picks to maneuver around the pins in the AR1 and SX keyways, you're ready to start actually opening locks. The basic skills of pin tumbler lock picking include selecting the proper tools, manipulating pins through the keyway, applying torque, and recognizing the state of each pin. If both feel springy, you're not applying enough torque (which is unlikely). If you release pressure with your pick while still applying torque, the bottom pin will drop freely, and will not have any spring pressure if you try to push it back up. The pins toward the back may feel a bit different from the pins in the front. Lift each of the pins from front to back. Here the plug has been turned slightly toward the camera, so that the tops of the pins in the plug are visible. Longer handles are as a rule better in torque tools; the farther from the plug the torque can be applied, the easier it is to detect and control fine movement.
