While many of the principles of pin tumbler lock picking apply or can be adapted to other mechanical lock designs, a complete discussion of these locks and techniques for defeating them is beyond the scope of this document. There is a more detailed discussion of configuring training locks at the end of this document. While there are literally thousands of different keyways in commercial use in the United States and thousands more abroad, these four give a fairly representative sample of the different kinds of wardings (and pin manipulation problems) you are likely to encounter in common (non-high-security) locks. It's important to be able to distinguish among these four states. The pins toward the back may feel a bit different from the pins in the front. You may want to use one of the smaller torque tools as well, or put your torque tool in the bottom part of the keyway instead of the (curvy) top. Eckert, Ralph (May 8, 2015). The Sport of Pool Billiards 1: Techniques and Training Based on PAT Part 1 (ebook). Find the ward directly under the pins and pivot the shaft of the pick at the font of the keyway.

Now, while continuing to apply torque, insert your pick and find and slowly lift the pin stack. You will need a small set of cylinders in various keyways, a board or vice to hold them in while you practice, and a small re-pinning kit (extra pins and springs and a "follower" tool). WPA professional competition generally employs regulation tables, while the amateur league championships of various leagues, including BCAPL, VNEA, and APA, use the seven-foot tables in order to fit more of them into the hosting venue. The Peterson picks are more sturdy, at the expense of being bulkier (but they still fit easily in many of the keyways you'll be picking). This keyway is a bit more "open" (it's intended to allow several different key profiles to fit in it), and so requires the use of a larger pick than the Arrow AR1 keyway does. Note that the pick should be held mostly by the shaft of the tang, What is billiards not the "handle." This allows better control and feedback. The cue slides through and you use your other fingers to keep the cue from moving sideways.The open bridge is better for softer shots and is preferred by players who have trouble making a closed bridge.

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. Small digits represent short bottom pins (that must be pushed up more to reach the shear line); large digits represent longer bottom pins (that need only be pushed up a bit). Figure 4. Manipulating pins. Figure 3. Holding a pick. See Figure 5. With the tool in the keyway, apply torque and try to turn the plug. I usually find that the very top of the plug, directly in front of the pins, to be a good place to apply torque, but you have to be careful that the tool doesn't touch the front-most pin. Well, I have a sort of suggestion, and that is this: that, before we decide either to save the planet or destroy it, we pause for a moment of silence. It can become very tempting to "cheat" a bit here and move ahead the moment you get a difficult lock open the first time, but that will only make the rest of the course that much harder.

Basically, the point here is that modelling impacts like these is a tricky business. You'll probably find the large hook or deep curve pick works well here. You'll probably end up deciding that the small Peterson hook works best, but experiment with all the picks. This pick is a LAB double-ended "hook/rake" (held for use with the hook end). And whatever you do, please don't remove them from the lab without checking with me first! 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. However, your efforts un-pinning and re-pinning locks will be time well spent -- you will progress much faster than you would if you tried to start out picking fully pinned cylinders. See Figures 3 and 4. Once you're comfortable with the AR1 keyway, move on to the "Ilco SX" keyway locks and repeat the exercise. Go back to the "Arrow AR1" keyway lock board and find the one pin lock. Each board is labeled with its keyway, and each lock cylinder on a board is labeled with the number of installed pin stacks (from one to six) and the keying code for its pinning.
