These are the instructions for my very own K'nex lock, first shown here.  The locking mechanism is powered entirely by tension, and when closed, it’s impossible to open it with force unless you rip apart the lock itself, or bend the pieces enough so you can yank the shackle out.  It is opened by pressing the button on the side shown by a note in the intro picture.   I could mess with this lock for hours.  I wouldn’t recommend actually locking anything with it, because someone’s just going to disassemble it.  Bad things could happen to your sweet loot, and we certainly don’t want that.

Step 1: Piece Count

Connectors:
White Eight-Prong: 2
Red Three-Prong: 18
Grey Two-Prong: 3
Orange Two-Prong: 7
Grey One-Prong: 11
Tan One-Prong w/ Extruding Bit: 4
Orange One-Prong w/ Extruding Bit: 1
Small Blue One-Prong: 3


Rods:
Green: 23
White: 17
Blue: 3

Miscellaneous:
Y-Rods: 6


(It's always useful to grab a few extras just in case I'm off, and if I am inaccurate in the piece count, please tell me.  It took a while to make this piece count, but I am only human, and I easily could've made a mistake.  If you're confused about what piece I'm referring to when I assign it a name, please don't hesitate to ask.)

Step 2: Shackle

This is a rather long step in which you build the shackle.  The shackle was the most difficult part of this design, because I had to remake it multiple times so it could be as sturdy as possible, yet relatively thin, with a sizable hole in the middle.

Step 3: Lock Box

This is the part where all the magic happens.  Here, you build the mechanism that allows the lock to lock.

Step 4: Connect the Shackle & Lock Box/Finishing Touches

Finish it all up.

Step 5: Hours of Mindless Entertainment

Listen to this playlist or anything you want (relative silence works too), contemplate the universe, and fiddle with the lock you just built.  You've got enough mindless entertainment to last yourself quite a while.  Have fun!

<p>What is Orange One-Prong w/ Extruding Bit?</p>
<p>I like it! The design and compactness are awesome!</p>
<p>hmmm i should build this...</p>
Hey man, thought I'd add to the build streak and make one too! I didn't time myself though...
<p>My, the list of builders just keeps growing. Timing, schmiming. Thanks for taking the time to build this. (The mechanism is working for you too, I assume?) </p>
<p>Sure, it was a cool build, and yes, it worked fine! </p>
<p>Ooh, K'nex lighters. That, my friend, is brilliant. :3 (I'm glad it works for you.)</p>
<p>Haha yep!</p>
<p>It looks more like a lighter than a lock though. :P Wait.... (Idea pop sound).</p>
<p>This looks really nice bro! I have heard that a lot of people have built it! Congratulations! I just can't break myself from the world of K'NEX guns... D=</p>
<p>Yes, this 'ible has my personal record for people who have built it, and I'm quite proud of that. ^&not;^</p><p>I understand: you are on a mission to build as many awesome K'nex Model Guns as possible, and you're doing a marvelous job. Keep it coming, and you don't really need to worry about breaking yourself from K'nex gun land. &oslash;_&oslash;</p>
<p>Great! Thanks man, I am glad that you like some of my builds. =D</p>
<p>This totally owns! After gathering the pieces, it took me 6 minutes 43 seconds to complete it! Awesome lock!</p>
<p>That looks awesome, my friend. I'm glad that you built it and enjoyed it. Six minutes and forty three seconds, huh? Speed building challenge, guys. We've gotten impressive record to start off with. Any challengers? (How off was I on the piece count for green and white rods? I'd like to fix that if possible.) Thanks for sharing.</p>
<p>Oh yeah! I forgot, you just got a vote and a subscriber! =D</p>
<p>The vote and subscription are greatly appreciated; thank you. Welcome on board the Dark Owl party train. We shall see if your record stands. :p</p><p>I'm going to fix the white rod count now. Thanks.</p>
&quot;Welcome on board the Dark Owl party train&quot;<br> V .gif
<p>Suggestive eyebrows indeed. (It's a .gif)</p>
<p>Oh, if only he knew the joy that is the Dark Owl party train earlier...</p>
<p>If only... Eyebrow game strong, Mike.</p>
<p>Oh, but we can now show him our ways on the party train</p>
<p>Yes, aks, we welcome you aboard the party train. Mike and I will show you the way it's done around here.</p>
<p>&gt;Aks's face when he finds out what the daily activities of the Party Train are </p><p>(on a side note, omg, no eyebrow GIF :o )</p>
<p>Everyone when aks joins the party train and we ride off to the glorious party land where we all shall all flourish and party forevermore:</p><p>(We can start the eyebrows again at any time or any place. Just name it, and it shall begin.)</p>
<p>Oh, this party will last forever. And if it, by any chance, does not, I still have some ideas...</p>
<p>All right! Your ideas will keep the party pumping not just forever, but 5ever!</p>
<p>Hmm, but how can this party last without Akshat, or others? I mean, it's fun with you, but extra people = extra funfuntime. Come on Aks, don't be shy, we're waiting for you...<br>(omg, no .gif)</p>
<p>Well worded. Yes, everyone join in on this wonderful comment chain of insanity. (.gifs are back, Mike!)</p>
<p>:D<br>Yay, .gifs :D</p><p>Dance party time!</p>
<p>I don't understand you guys...</p>
<p>Um... thanks? I am totally freaked out by all those GIFs. What is with the eyebrows?</p>
<p>The eyebrows represent what the Dark Owl party train is all about. Sorry for all of the weirdness, but it's a part of what the Dark Owl party train is all about. Please rest assured Mike and I are having this cultural exchange for the benefit of the K'nex community and society as we know it. Feel free to join in whenever, or just watch, amused, whilst being very weirded out. Either one is perfectly okay aboard the Dark Owl party train. All aboard!</p>
<p>Board the train, aks, and come with us to party land!</p>
<p>Ow I guess it stops at platform 9&frac34; ...</p>
<p>We'll wait for you there, just come on time!</p>
<p>Yep, it works perfectly too! I don't guess I'm the best at speed building, and I guess most people can beat me... (I least I think so!). Yeah, I guess I was wrong about the piece count, green rods are correct but white rods are wrong. There are 17 white rods, not 16! Well, I guess that's ok!</p>
Built worked perfectly. Amazing job!
<p>Awesome. I'm glad to hear it!</p>
<p>Awesome!</p>
<p>Thanks!</p>
<p>No problem, I like the system. :)</p>
<p>Yo DO! I just made another one and combined both to form handcuffs! Of course, it uses more parts but they actually work (but they do break when you apply <em>too</em> much force)! Want some pictures?</p>
<p>Yes, I'd love to see some pictures. You can feel free to post it too if you give me credit and link it to this. They sound awesome. :p</p>
<p>Ok! I'll post an i'ble on it! And I'll give you credit too!</p>
<p>I'm looking forward to seeing it. :p</p>
<p>Thank you; I'm glad you like the lock. </p><p>K'nex are surprisingly popular still due to one main thing: they're perfect for mechanisms, and you can make anything with them. You'll find that nearly all of us at the K'nex community on instructables aspire to become engineers of some sort, so mechanisms and building are the perfect hobby for us. K'nex is a wonderful medium to use for that.</p><p>(Your crafting is wonderful, by the way. I look forward to seeing more of your creations.)</p>
<p>Good job!</p>
<p>Thanks!</p>
<p>It's not just good stuff, it's fantastic stuff. :3</p>
Hey nice bro you're kneeing again!
