Step 4: Bend the clip some more!

Using your pliers, bend the tip of your clip into whatever shape your heart desires. The picture shows a basic curved pick.
<p>Question. Do I need to have the weird stain?</p>
<p>Cool but I already know.</p>
If you dont have a blowtorch, you can hold the paperclips with pliers and close one end in a drill and twist the wire for like 5 seconds it rearranges the molecules and makes it much harder.
Hardly anyone does water quenching anymore, most do air tempering. In this particular case you can probably get away with it. It won't turn the paperclip into glass, it would probably still take a good amount of force or very sharp movements to break it off and even if it did break, it's easily removable, but that's why you have practice locks, neh? For what it's used for, this process is fine. <br> <br>Here's an example of air tempering: <br>Heat A2 tool steel to 1750 degrees for one hour and fifteen minutes to one and a half hours. Remove from oven let cool for eight hours minimum. Heat the part to 600 degrees for thirty minutes then allow to cool. That will give you a Rockwell hardness of about 52 to 60 (that's hard enough that you can't file the metal, you have to use either a honing stone or carbide). If you want to figure out what kind of metal you're using, there are tons of charts that will tell you the exact temp and time you need to get a certain hardness.
I presume that would mean you would need a forge or something similar to keep the metal at temperature for those lengthy time periods. Is there a good way to air temper using more general purpose heating sources (like a torch) or is it simply a matter where &quot;if it's worth doing right, it's worth the investment.&quot; <br> <br>If that's the case, water quenching seems like it may still be good for the casual &quot;blacksmith&quot; (and I even use that in quotes loosely), who just wants to dabble once or twice with it and move on to the next kind of project.
The gas fired forges I've seen here would do okay, so long as there wasn't a huge temperature fluctuation but most use an electric oven designed for that purpose. <br><br>For all intents and purposes, especially for small pieces like this one, yes, water quenching is fine. I was more adding specific information about the process. I've used water quenching for horseshoes almost exclusively and have never had a problem. <br><br>Though now that I think about it, you could probably whip up a temporary gas forge with firebricks, some black pipe, a mixing valve and some of those propane torch sized oxy acetylene tanks if you put your mind to it.
Wow nice tension!<br> <br> grtz,<br> <br> Koen<br> <strong><a href="http://www.lockpickwinkel.nl/" rel="nofollow">http://www.LockpickWinkel.nl/</a></strong>
but putting hot metal in water makes it brittle
yes and putting it in hot or warm salt water and cool it down slowly makes it juuuuust right. depending.
Yay 4 Che!
yes it dose make it brittle if you get it to hot and quench it to soon. its a balancing act if its to hard it will break in the lock and if its to soft it will bend in the lock (btw)"the katana and other swords in it's family have 2 different grades of steel in the blade a hard steel to keep an edge and a soft steel so the sward wont break on impact"
putting something really hot into the cold water will set the molecules. If done properly the metal usually turns a solid color, but if done improperly, it will change into a spectrum of colors.
not always sometimes it does sometimes it doesn't
so what do I need the weird stain for?
You wanna play Secret Agent, that's fine, but if you get caught in the wrong place at the wrong time...those will be considered burglar's tools...and you get to hire the lawyer to prove they weren't. After you get out on bond, that is.
Too true. In the UK it is known as 'going equipped'. Without being in the guild of locksmiths, you're probably best of using these in the safety of you're own home.
&nbsp;Would this work just as well with a gas stove top?
I tried it with my stove, and the first time it got softer, but I did it a second time and it worked.
the stove doesnt work to well.... there is a technique call tempering. it heats the metal and leave to cool, and then it will get softer, you need speed to do it wiht the stove..
it works better if you use a bobby pin and you dont have to do all that reheating
&nbsp;The tempering process all depends on the temperature of the steel right before quenching. &nbsp;When I do my chisels, I get it red hot, pull it out of the forge, then quickly grind off the black carbon with a grinder. &nbsp;A rainbow of faint colours will appear, and they will change colour as it starts to cool. &nbsp;When the tip of the chisel is just starting to get to the yellow end of the spectrum, that's the exact time to drop it in my quenching oil. &nbsp;Never tried a thin paperclip...<br /> <br /> <br />
instead of using just water mix salt, dawn dish soap, and jet dray the ratios i have are for a 5 gallon bucket so i'm not sure on this for small ammounts. just add good amounts of all of it. <br /> <br /> this will provide a much better hardening then just using water. this actually adds a bit a of carbon to the steel.<br /> <br /> this will probably make it more brittle so be careful not to break your pick off in the lock. <br /> <br /> <br />
Do that about 2 times the heat it up again and let it cool so it will be hard and wont brake.
On the contrary, multiple temperings (in uncontrolled conditions) will make the steel very brittle and it will crack inside the lock. That is very bad. <br />
here's my idea: temper, quench, temper, quench, temper, let air cool.
Careful on this. i tried 1 temper-cool cycle, hard! when i did another one i expected it to be harder, but it is more bendy than a regular ppclip<br />
weird, i wonder if the laws of chemistry, thermodynamics or even court-type law apply?&nbsp;
pun intended
True but you need to know when to stop not like i do it 20 times so that probably wont happen<br />
but then it will be very brittle or too soft
Mine works fine it doesn't bend.
hmm, well Ill try it then
&nbsp;dos it really work<br /> <br />
A nice and to-the-point instructable. I just now tried this with a smaller butane jet lighter (~2.50 USD from Walmart) and I'm rather pleased with the results. But of course I won't know for sure until I give it a try I guess. :D
yes, i hate those disclqaimers. its not like youre telling me to rob somebody, and im not a meanie. you should in no way be lyable for any of anybody ealses mistakes
Where to get tension wrench`?
any tips on making a tension wrench? :)
ummm.... nice pic
heh :3
*resists /b/tard instincts*
another instructable is soon to follow
isnt it dangous to light a torch with a match? shouldt you use a flint striker?
It is. Why dont you heat it up wih a lighter? the thing looks even more dangerous than a lighter. It looks impressive(The torch, nt the lockpick) but it is also dangerous.
no, I don't hate it when people put in those disclaimers.
Coulnt you take the 'bendy' one and temper it? It looks like more of a tool with a handle for easy of use...
You'd have to do the whole handle part to, otherwise just the end would be stronger, and you'd get a twisty part where you didn't heat and put in water.
I was thinking the same thing. Much more easy to maneuver when there's a handle attached!
