If this happens, you won't get the lock open until you release torque and start over. It's possible that the plug will turn as soon as you set the first pin; if this happens, it's because you inadvertently lifted the other pin with the shaft of your pick while you were working on the first one. It is usually possible to insert the torque tool at either the top or bottom part of the keyway. Insert the tip of the tool in the keyway, allowing enough room for your pick to enter and manipulate the pins. The Peterson "Reach" deep curve pick works well for this keyway, pivoting from the bottom of the keyway at the front. As you lift the pin stack with torque applied, eventually its cut will reach the shear line, allowing the plug to turn; the top pin will then be completely trapped in the shell, while the bottom pin stays in the plug, no longer held down by spring pressure.

It moves freely up until it reaches the shear line, where it "hits a wall" and can move no further. When the pin stack truly sets at the shear line, it will feel like an ordinary set pin. This is not a problem for the computer, who can easily jump to another line, but it makes difficult for most human programmers (excepting perhaps the original programmer) to comprehend the totality of the programme well enough as for making changes into it without also introducing some error or unexpected behaviour in another part of a long and complex programme. In this article, we will discuss the importance of comfort in billiard room chairs and what factors you should consider when making a purchase. Do not assume that the next pin will be adjacent to the one you just set. Learn to pick this lock one pin at a time. This pick is a Peterson "Hook" with a plastic handle. The picks are available with blue plastic handles. You may find one of the smaller LAB hook picks to be easier here than the larger Peterson picks, although you can usually still pick this keyway with the small Peterson hook.

While the LAB picks are quite nice, their small size makes them rather delicate and easy to bend or break, especially as you're learning how much lifting force and torque are involved. Lifting pins is one of the basic actions of lock picking, and it's worth taking the time now to become good at it. 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. The shape of the tip is the most obvious difference between picking tools, with hooks, half-diamond, ball, double ball, wave, sawtooth and other styles available. Chalk. Pool chalk is used to help prevent the tip of a cue from slipping when it hits the cue ball. This shot involves striking the cue ball in a way that it contacts multiple balls consecutively before pocketing the intended target ball. It may be inferred that it developed from a variety of games in which propelling a ball was a main feature.

If you inadvertently push a pin up too far or are applying so much torque that more than one pin is binding, you may have an overset pin instead. Better quality locks are less forgiving of too much torque. Many inexpensive locks, especially low-security "cam" locks such as those used to secure furniture and cabinets, do not use pin stacks for their tumblers. For most of the picking methods discussed here, in which tumblers are manipulated one by one, a "hook"-style pick is generally used. Another style of torque tool has two "prongs" that fit in the top and bottom of the keyway, with a cutout between them for the pick. See Figure 5. With the tool in the keyway, apply torque and try to turn the plug. Figure 5. Applying torque. If both resist, you're applying too much (the more likely mistake). It feels much as it does when binding and unset, but will not set (since a binding pin can only move up, not down). Many manufacturers outfit their picks with elaborate and supposedly "ergonomic" handles, but these often hinder performance as much as they might enhance it.
