    Simple Homopolar Motor

    Dope was a chemical suspension used to make flying model airplanes in the early twentieth century. The original term doop meant a suspension of material in a liquid medium (glue, paint, soup, and medical concoctions were called doop mixtures but in the early 1900's Dope usually meant a specific type of mixture). We would build a balsa wood frame, then cover the plane with a special paper that was very thin and made with silk threads, that, when covered with Dope would tighten up and turn rigid. The Dope was made with chemicals that were poured on cloths and then sniffed by teens looking to catch a buzz. These chemicals caused lung and brain damage when breathed repeatedly, causing dizziness, loss of memory, and general cognitive damage. This led to asking people who made less than in...see more »Dope was a chemical suspension used to make flying model airplanes in the early twentieth century.

These chemicals caused lung and brain damage when breathed repeatedly, causing dizziness, loss of memory, and general cognitive damage. This led to asking people who made less than intelligent statements, "What are you, a dope?" indicating one who got Doped Up by sniffing paint and dope and other doops. When certain chemicals became illegal to teens, making certain paint and other products hard to get by non-adults other products were developed for model plane building. Now we use shrink to fit plastics and laser cut balsa wood to build model airplanes. By the mid twentieth century the term dope had come to mean anyone who had a lower than normal mentality, or any material used to produce a buzz or high, specifically marijuana and illegally acquired and utilized drugs. In the late twentieth century the use of steroids became illegal in commercial sports, and because there were many who used steroids illegally, it also became known as doping because it became known that too much steroids again limits mental capabilities.Eventually the people who used illegal substances were called dopes, and using the substances became known as doping. Those who sought out the most mind affecting chemicals and drugs as a form of entertainment would call high quality or high strength drugs and chemicals as "The Dope" indicating the highest form of the particular chemical or medication. To the under society of people who use these products "The Dope" has come to be used to indicate anything that is desirable in the best quality, or highest desirability.

    How to Pick a Lock (Basics)

    Unfortunately you are correct, most of the people I have met in my time that wanted to become a locksmith did not want to learn how to pick open locks because unless you want to preserve the lock there is no reason to do so. Drilling the sheer line takes about 20 seconds and works every time, they think "Why learn a skill that prevents me from selling a new lock? If I drill it, the customer gets in and the lock gets replaced, generally by a more expensive one that has anti-drill features." A locksmith today is not appreciated for bypassing the locks without damage. Also hardware stores have stolen the lock and safe business by selling really cheap versions that make people believe they are getting a deal.

Drilling the sheer line takes about 20 seconds and works every time, they think "Why learn a skill that prevents me from selling a new lock? If I drill it, the customer gets in and the lock gets replaced, generally by a more expensive one that has anti-drill features." A locksmith today is not appreciated for bypassing the locks without damage. Also hardware stores have stolen the lock and safe business by selling really cheap versions that make people believe they are getting a deal. So, the locksmiths have to match the price of the hardware store, or only sell quality locks, when we sell quality locks, 80% of the populace believes the locksmith is cheating them when it is the hardware store that is reducing the quality of what people are willing to spend on locks. They think the $20 at the hardware store is the same lock they would pay $40 for at a locksmith, but in most cases that is not the case, a locksmith becomes legally responsible for selling a product that is inferior, so does the hardware store, but most people would never sue a hardware store but they would sue a locksmith that makes their home or business vulnerable. Locksmiths used to be the only place to go to get a key cut or a door lock rekeyed, or to have a safe installed and maintained, but today that doesn't happen. Electronic safe locks are the normal type now, even though the mechanical type are long lived, an S&G #3 type safe lock cost about $170 and lasts for thirty or forty years with proper maintenance, but now you can get an electric one for about the same price, but it only comes with a 90 day warranty and will likely stop working within five years. They are just as secure as a mechanical lock but the parts are designed to fail, again, you can't make money unless you are selling new products.So, keep buying your locks at a hardware store, where the hardware is manufactured in China, and designed to keep no-one out who wants in. Then when you simply have to pay the locksmith for his skills, he will have to charge you more for those skills that are not available through the hardware stores just so he can make a living. The old adage is still true, you get what you pay for.Don't pay a professional what they want to make you a key when you don't have one, if you have the code, generally it is cheaper to make a key off the code, but if the lock was ever re-keyed, which was very common on older autos, making a key by code is only guaranteed to produce the key for the code, making a key for the lock without a key and without damaging the lock is a different process than picking the lock. Picking the lock has no relationship to making a key, so just asking someone to pick a lock is often the wrong approach.

These keys cannot be duplicated they must each be originated because of their unique angled cut patterns. The doors were also nothing like what you would find in your average neighborhood.

    As a locksmith of over forty years I can tell you that reading this information alone will not allow you to suddenly be able to pick a lock, just like the so called INSTRUCTABLE on opening disc tumbler padlocks, this information is strictly about locks that are cheap. Any lock worth having uses either different methods than put forward here or use pins that are specially designed which produce many false sheer lines, the more of this type of pins in the lock, the harder it is to pick. If you are concerned about this information being out there, call your local Locksmith and ask about pick-proof and un-pickable locks. WARNING locks that are pick-proof and un-pickable are expensive.

Any lock worth having uses either different methods than put forward here or use pins that are specially designed which produce many false sheer lines, the more of this type of pins in the lock, the harder it is to pick. If you are concerned about this information being out there, call your local Locksmith and ask about pick-proof and un-pickable locks. WARNING locks that are pick-proof and un-pickable are expensive. You can buy a cheap lock at your local hardware store for under $80 for a lock that can be installed in Residential or Commercial doors (They are adjustable) and they can be picked as this article suggests, by a skilled person, they can also easily be opened by; kicking the door in, using a large hammer to knock the handle off and use a screwdriver to force the latch, or, even easier, use a portable drill and drill out the sheer line on the cylinder then use a screw driver to turn the cylinder, or use a gun and shoot the lock to pieces.If you want to secure something, say a computer that cost $1200 or more, or a Flat Screen TV that cost $3000, jewelry that cost tens of thousands of dollars, then don't put a cheap lock on your house door that can be opened easily with a large hammer in a few seconds, or with years of practice, picked open by a professional.M_____o produces a lock that is so nearly un-pickable that it has only been known to have occurred once. Ever! Their lock uses specialized pins that are slotted and have angled tip pins that have to be rotated to the exact angle which allows a sidebar to then push into the pins, and clear the sheer line for rotation, the lock handle and assembly are made from high strength steel and all vulnerable drill points are protected by hardened steel roll pins and ball bearings which break drill bits when attempting brute force methods of bypassing, of course, they cost a lot more than your average lock. Other lock companies also use side bars with other pins or wafers. These locks have a tolerance equivalence of 1/1000000 of an inch, where the locks that this article talks about have a tolerance of 2/1000 to 4/1000 of an inch. This is the difference that makes a lock easy or hard to open, the smaller the tolerance, the harder it is to keep each pin at the exact sheer point to allow turning. Also, locks wear with age, so if your lock are real old, the wrong key can be used to pick the lock open, simply by wiggling, this is most common on vehicles made in the last century as many of them use thin wafers instead of round pins.Kw___t locks used to use pins that were beveled for 15/1000 of an inch where the pins meet, this was to allow the keys to easily be inserted and used many hundreds of times without having to service the lock, but the down side was that it increased the picking tolerance to about 22/1000 of an inch, so they were one of the most pickable locks available, they have stopped making their locks that way, reducing the tolerance and increasing the security. The down side is that it is important to keep the locks clean and lubed as a small amount of dirt and grease can prevent easy opening.Sc____e was for a long time the leader in Commercial Grade locks in America, their tolerance was generally 1.5/1000 of an inch. making them hard to pick without a lot of practice, then they added an extra pin, making it an additional 20% harder to pick. But then in the late 90's they decided to compete with the cheaper made locks that flooded the market, so they produced their F lock, instead of trimming the pins, they shaved the top of the cylinder down providing about 15/1000 of an inch clearance, if the pins are that close to the sheer line, the cylinder turns, so if you bought a lock because of the great name they had built up, you were in effect buying a lock that was easier than the cheaper ones to pick open. When it comes to locks, you get what you pay for.So, if you want to secure yourself against people who will actually read this article, will spend the many hours required to learn how to pick most locks, regardless of the tolerances up to about 1/1000 of an inch, and then instead of using those skills to make a lot of money as a locksmith they decide thievery is the way to go, well you can rest assured they will not be able to pick your locks if you buy brands like Medico, Assa, Abloy, Best, Tubular, Duo-Key (Two Bladed Key), Mul-T-Lok (pin within pin technology) and of course the newest kids on the block, Electronic keys, near field communications locks, and Active Radio Card locks and so on. Swipe card locks are the Cheap versions and should be avoided unless securing the door against intrusion some other way. The electronic locks have a lot of vulnerabilities that mechanical locks do not, but we will have electronic locks that are as secure as the most complex mechanical locks, but they are very expensive, and unless you need to keep everyone out, and keep track of who enters the room and when, then mechanical locks are the more effective solution.Don't get upset with the person who wrote this article, and others like him, they are simply people with a little bit of knowledge, enough to be dangerous for sure, against the average person, but at heart they get a thrill by telling what is generally considered secret, these are not the kind of I would want as a friend or even acquaintance. The solution, don't be average, know that this person is simply exposing the vulnerabilities of what is common and cheap and in truth provides only the first step to those who would be thieves and crooks. From personal experience I can tell you that picking locks is only practical for one thing, bypassing a lock without damaging it or the door. There are many more methods of bypassing locks that are much easier, faster, more practical and less work if you want to be a thief. If you learn to pick a lock from this article, get a better lock, immediately. If this article leads you to be able to pick more than ten different brands of locks, seek out a job with your local locksmith, then you can learn how to open cars, safes, businesses, and how to install them all and most importantly how to secure homes and businesses with more than just locks and keys.
