TR8, NAR, and the ZKAR

Hey guys, It has been some time since I posted a new forum topic, but I am not here to ramble about time lapses. I want to know where I can find instructions on how to build the TR8. I plan on doing an 'ible that features the TR8, the NAR, and the ZKAR, so that I can have said that I built them, and so that I can see for myself weather they are all what they are made out to be. I understand that the NAR is essentially a mod to the TR, so I want to build a TR8, so that I can build the NAR. Help please! -The Red Book of Westmarch

How do I build the NAR bullet lock? Answered

I know there are instructions for the NAR on K'nex Innovation, but the pictures of the bullet lock are too blurry. Can someone please post some clear pictures?

NAR bullet lock and barrel Answered

I am really confused by the front of the NAR, can someone help me? I don't know what piece fits in the barrel or how it fits in it, if you can post a picture that would be great.

NAR strangeness NOW WITH PICTURES

So I was testing my NAR and my TR18 next to each other and noticed that the NAR doesn't really like finned  rods.  In some cases it actually shot normal red rods further than finned ones; anyone else noticed anything like this? I'm sure it's not a problem with the fins; my TR18 shot them about twice as far with the same bands as the NAR.  I think it may be because you have to place the fins further forward on the rod because of the bullet lock. On an unrelated note, I don't really make all that much myself, I modify other peoples' things, so if you want me to give any weapons a new better looking and more comfortable body (if you say a WORD about that DJ...), just say and I'll see what I can do.  I'll only accept your own designs, no volunteering others' work.  If you want me to do someone else's design, send them a PM and get them to speak to me directly.  And no TRs. I would upload some pictures of my previous work, but my library on the site has been mysteriously emptied, and I can't find them in my picture folders.  I still have a mod of SK's shotbow built, so I'll post a picture of that as an edit later if there's interest. EDIT:  Pictures of my shotbow, two very old Striker mods (IaC's Striker), an old one of my TR18 (I made it much better than it is shown here, but this is the only picture I could find), and something I think I modded from IaC's assault pistol (this one was one of my first attempts at a mod and isn' my best work).

DarkOwlKnex Project Update One

For two years or so before I joined site, I've been building K'nex guns.  Here are my two recent weapons of plastic destruction. The Oodammo pistol I built (The D2OP) or (The Dark Owl's Oodammo Pistol's) most interesting feature is that the mag tilts and locks downwards due to friction. It also features: A no rubber banding required trigger. A high mag cap. A comfortable handle (at least for me). Iron sights. The above mentioned magazine. All it needs is a better ram rod; I didn't put much thought into it. Second on the agenda, we have a NAR reminiscent pistol.  it, instead of using the NAR transfer, uses my own custom DOT system (Dark Owl Transfer). Yeah, I just made that up now.  It sounds good and everything.  Wow!  Actually, this gun has a name now; it's the DOT Pistol.  Funny how this works.  Anyways, this transfer is unique not only in its design but in its removability.  When you pull down the lock as shown in the pictures, you can take the transfer right out, turning it into a regular single shot if you so chose.   It's other features are: Very good range (I haven't tested it, but it goes considerably far with one rubber band). Comfortable Handle (But not as comfortable as the D2OP's in my opinion). Removable hatch DOT system (explained above). Bullet Lock. Sadly, it has no sites, but from what I've heard, not everybody wants them, anyway. Both of these guns are now posted with instructions to all those that are interested: The D2OP: https://www.instructables.com/id/The-D2OP-Dark-Owls-Oodammo-Pistol/ The DOT Pistol: https://www.instructables.com/id/The-DOT-Pistol-Dark-Owls-Transfer-Pistol/

DarkOwlKnex's Project Update Two

As my profile status has said for a while now: I've been working on a TR8 and I might post a forum topic about it.  This is the forum topic about it.  It's amazing how often I've been on lately, but don't expect that in the future.  I sort of don't have anything else to do with my time other than going to the library, taking walks (It's nice out where I'm at) and a few other things, but the bulk of my time, for the week, has been spent here.  Stuff I have to do will keep popping up from here on out.            I call this custom  TR8 of mine The AutoSuggestion.  Why?  Because it's the name of this one song that I like.  I realize that I should send a link to the song, but I figure since you guys won't like it anyway, what's the point.  (I have a weird taste in music) It Features: A comfortable stock. A comfortable handle.   A comfortable fore grip. Innovative new TR body design. I can't really say anything else about it until I'm finished; once I finish, I can you tell about the range, and other things.  I'm going to have to make many cosmetic changes before I upload it to the Rods and Connectors contest.  (Thanks, JonnyBGood for alerting me of this contest)  Any helpful suggestions as to what I can do to improve it would be much appreciated.  Thanks for viewing! Update: I finished the rough draft; the pictures will now show the latest version; it is now on the official prototype phase.  I'm probably just going to tinker with it excessively until it's perfect for the Rods & Connectors Contest. Update: Made it fire; gets decent range so far.  Installed turret rotating system; it requires bands, but is very easy to use.  Update: Cleaned up stock and barrel area.  I also made a completely new handle.

RTR

Hey guys, This is a transfer rifle that I made a few days back. It outwardly resembles the TR/NAR, but is totally different internally. It uses a true trigger mech that I invented, as well as a transfer mech that was also designed by me. It shot about 50 ft., but that was only with one or two old bands. It was really comfortable, and I would have liked to finish it, had I not taken it apart to build the NAR+TR8+ZKAR. Enjoy, and go ahead and ask questions if you have any. -The Red Book of Westmarch

Ranges on a knex gun gone wild!

There is no way that a knex gun can reach 60 feet using the simple ram mechanism. Ive made the NAR and fired it using 3 brand new #64 sized rubber bands and ammo with fins! It did NOT reach 100 feet or even 60. The NAR only reached 50 feet.Ive also built the TR Sayer and TR 8. They also did not reach the length that the owners claimed. Its really sad that people are putting high ranges even though they're all a lie! What do you think?

WHAT SHOULD I BUILD? Answered

I am looking for something innovative to build out of knex, and a new type of weapon. I have already made the NAR, and I am bored. please make sure it does not have a high piece count.

Knex War?

Hey guys! Sharir1701 here and, as most of you guys that knew me back when I was still around probably know, I've lost most of my interest in Knex. I do, however still come on the site ever so often to browse, comment and so on. I've noticed during my past couple of visits that there seems to be a "war", so to speak, raging on between some members of the community, regarding the effect of bulldozing a gun with rubber bands, as well as "how good" is the NAR. In this forum I am assuming you all have basic knowledge in Knex gun technology, are familiar with the stated guns and have a little bit of background in mechanical engineering. Moving on. You might know my opinion about the subject already, but I would like to state it once more as well as explain it better, so perhaps some people that disagree with me could understand my point of view. BUT, before I do that, I can't help but feel guilty for tossing the long burning logs into a small fire. About a month or two ago, in one of my visits, I posted a comment on one of Red's topics (or 'ibles, strike me dead for my memory) about my quite specific opinion about each and every one of the three guns in question in the said topic, the ZKAR, the NAR and the TR8. I said a few things about rubber bands and brute force vs. complexion and efficiency, and I may have started something unintentionally. That argument has been around since, if I recall correctly, 2009, but it hasn't been brought up again in a while. I feel like I made that happen and then I enraged a few more people by saying that "efficiency and good design beats brute force any day" (or something like that...). I'm not taking credit for starting this thing again, but rather I'm apologizing for sparking up an old and possibly pointless argument. Nonetheless, I will now explain my opinion on the subject and hopefully nobody gets mad at me for doing so, but if you have a valid counter argument, please state it below in an understandable and polite way. Thank you. If so, then, what is this whole thing even about? The "KI Crew", as I like to call them, have been very proud of their NAR and TR-n series guns for a few years now. The TR series I'll admit is very good, but I don't accept the "add as many rubber bands as possible" argument. Now, the NAR, personally, I dislike the gun. I have had nothing but bad range tests with it in the 3 times throughout the past 4 years that I've built it, and I've heard similar results from several people and some close friends. I highly doubt I was doing something wrong all THREE times, so don't bother to bring that up, please. The NAR is a gun designed for nothing else but being capable of withstanding great amounts of force and shooting a single round "the strongest a pin gun can shoot". How? Very simple - make a massively dense and very shock-proof body and then just add as many rubber bands as you can before your hands start bleeding. Now, let me explain, I'm saying 2 points here. First, the NAR is nothing special, just a strong structure with a simple connector barrel and a reinforced pin. We've seen it before, people. The claim that it's a good gun simply because you can put on as many bands as you want, pretty much, is, in my eyes, invalid. So I can make a bomb and just put as much explosives on it as I can afford, surely it'll be better than an atomic bomb... WRONG. It won't. Theoretically, even if it makes a bigger bang, it takes so much effort and it is so non-elegant that it loses it's point within itself. (Do not take this metaphor out of hand! You know what I mean). Second, and more importantly, I'm claiming that even if my first claim is wrong, if you look at the technical side of things you'll see that the very premise that adding more and more rubber bands to a gun will make it much stronger, is wrong in it's origins. I'm sure we all know this, but let me remind us all the physics of how a basic pin gun works. When the potential energy stored in the strained rubber bands, and rested on the cocked pin, is released, it accelerates the pin. The pin then proceeds to gain speed and it reaches three main milestones:  The initial strike of the bullet (The pin is already accelerated and is just touching the bullet, but the bullet is still). The point of equality, as I've dubbed it before (Just a few tiny fractions of a second after the initial strike, at this point the pin is ever so slightly slower than it was in the initial strike, but the bullet is now travelling at an equal speed as the pin, with a tiny gap between the two, meaning they aren't actually touching at this point) And finally, "the crash" (the bullet has left the barrel, the pin is at it's highest speed and is the most energetic as it pointlessly crashes into the back of the barrel losing and wasting all of it's remaining energy). In a world where you could use 100% of the acceleration of the pin and transfer it all into the bullet, adding more bands would indeed make a much stronger gun. BUT, that is impossible, in fact, it's no where near that. To put it all into a short sentence, the bullet accelerates and fires with a fraction of the energy released during the shot and to a certain limit, it is almost exactly the same amount of energy after a certain point. So, let's talk Maths. There is a direct correlation between the number of rubber bands on a gun and the amount of acceleration (and force) in the pin when fired. The pin's acceleration as a function of the number of rubber bands on the gun is in the order of magnitude of y=x. That's true, and that is where the misguided claim in question comes from. However, if we take a look at the graph of a bullet's acceleration as a function of the number of rubber bands on the gun, we can conclude, according to the above explanation, that the function is in the order of magnitude of y=sqrt(x). That means that up to a certain pivot, which I claim is, on average, around the 2-3 rubber band mark, adding more rubber bands does in fact produce a drastically stronger shot, but past that point, adding more rubber bands adds more brute force, yes, but it makes the shot stronger only just slightly, and by an increasingly smaller amount the more bands you put on it. BUT, and this is the big BUUT, the graph of the force required to cock the gun as a function of the number of bands on the gun is, again, in an order of magnitude of y=x. In conclusion, up to a certain, quite low point, adding more rubber bands will give you a drastically stronger shot without stressing the gun too much and without making the pull incredibly hard. However, past that point, adding more rubber bands adds an insignificant amount of power to the gun while introducing a whole lot more difficulty in operating it, resulting in an overall, worse gun. That is why I claim that a gun built around the sole concept of being capable to handle a lot of rubber bands is a nice concept, but is much worse than a gun built around efficiency (meaning you try to invest as much of the potential energy of the pin into the bullet by making a more efficient layout and a smarter usage of the forces in play). If you got this far, thank you for reading my article, and I hope this will put an end to this silly argument, but knowing how people's feelings work and how male ego and testosterone works, I bet it's far from it. Happy Knexing everybody ;)

OMG LOOK NOW !!!!!!!11!!!!!!!111!!!111!!!!!

So i just got the original knex roller coaster and i wanna build some stuff but dont know what to build so help me out and post a gun in a comment that will fit my criteria -has to have a range of atleast 70ft -has to have a comfy handle -or if its a model it has to be a really good looking model and i already have the nar, tr18 , and the freeslinger, but id be willing to take something apart or use the knex in my bins to make something with a lot of pieces.

Just a Thought

Hello everyone, I'd like to share a thought that occurred to me. It appears to me that there are really only 3 main qualities of a knex gun: -Range -Fire rate -Ease of use Now out of these three we have already maxed out range with slingshots and the NAR. Now we need to work on maxing out the other two through semi autos and such and we will have truly revolutionary weapons. Then we can start combining multiple elements and creating easy to use semi-auto slingshots and such. I just wanted to share these thoughts with the community.

Listen here...

Hey guys, I have been contemplating this forum topic for quite some time. I have debated with myself as to whether I should post a topic like it, or just ignore the problem(s). I have decided to go with the former, as it seems to me that there are things that need to be addressed. Not everybody is going to like/agree with what I have to say, but, I have always though that the best way to get people to think is to displease them. I have noticed that for some time now that people will spend more time talking about their own guns than the gun that they are posting the comment on. In other words, imagine that you have posted a new gun, and some person leaves a comment that looks somewhat like this: "Nice gun! I an currently working on a new crossbow that I think you will really like. It gets 100 ft. of range, it looks awesome, and it has a great 're-load time.' I hope that you check it out when it is posted, and give it a vote in the contest that it is posted in." I would humbly submit to you that that entire message is spam. If you are going to leave a comment on somebody else's 'ible, please do. BUT, don't make 95% of the message about how awesome your new gun is/whatever. The message is supposed to be a comment about/on the 'ible you are posting that particular comment on. It's kinda annoying to look at my own (and other people's) 'ibes just to find that they are full of "my new gun is posted here" type comments. Secondly, I want to talk a little about the classics. No, not classic music, but about the classic K'NEX guns. I will make this as clear as possible. The TR8/18 and the NAR are (in my opinion) outdated. Yes, they may get good range. Yes, they may only use a few amount of pieces, but this is NO excuse to bombard every 'ible with "well, this gun is good, but it is not as good as the TR8/NAR." I mean no offense, but nobody cares. I really don't think that anyone is trying to rival those guns, but there are guns that do so. The TR8 and the NAR may have been good guns, but they are from 2009, the K'NEX community has moved on. You may want to argue with me, but I will probably end up ignoring you. Sorry for making this comment so long, but those problems really do need to be addressed. I did not mean to offend anyone, and if I did, I am sorry, but you must understand how I, and multiple others, might feel. Peace. - The Red Book of Westmarch

2 ways to have more fun with knex guns.

So the number 1 thing to do with knex guns is to organize knex wars.  But what if you can't go to a war?  Don't worry, I have come up with 2 more fun things to do that don't involve nearly as much organization and knex as a knex war.  To make it more fun, I have made a point system that gives you bonus points depending on the scenario. 1. The hit and run (20 points) 1. Gather up 2 friends and give them guns.  The guns you will use should have a fast ROF, like a knexsayer, ZKAR, or handle pump TR. 2. Pick out a house.  Have your friends go on each side of the door of the house, while you stand directly in front of the door. 3. Ring the doorbell. 4. When victim opens door, open fire! Bonus 5 points if you emptied 5 or more shots from your gun before the victim reacted Bonus 15 points if you got your ammo back. Bonus 30 points if the victim waved his fists in defiance and vowed revenge. 2. Hit and run- soliciter version (20 points) You know those guys that hang around stores and sidewalks with cardboard signs asking for money and stuff?  Well go get a NAR or a TR and have fun! 1. Go find one of these solicitors.  They usually hang out in front of big chain stores like WalMart and Target.  They might even be at the local mall. 2. Pull out a TR or a NAR and shoot a few rounds into their cardboard sign. 3. Repeat until you get chased off. Bonus 10 points if they had a sandwich sign or a 2 piece cardboard stand sign and your shot went through both ends. Bonus 20 points if said solicitor was working for a charity like the salvation army. Bonus 5 points if you got kicked out of the venue. Bonus 10 points if you got your ammo back. Well, that's all I have time to post.  I'll post some more stuff later on, k?

Let's Do Some Testing for a 3-Month Pro Membership

One of the things that I have always wanted to do since I started "K'NEXing" (building with K'NEX) is to just sit down and start measuring, testing, and trying out new guns, different types of ammo, things like that. Then I realized something... I am way to lazy to do all that "work." So then I thought, well, maybe I could...*cough*... bribe other people to do it for me. So if you are at all interested in winning a 3-month pro membership, read the rest of this post. In order to win a 3 month pro membership (and a patch) you must do one of the following things: 1) Build a TR8 (no mods please) (only using 2 size #64 bands) and use it to shoot the following ammunition: Finned red rod Red rod Yellow rod Oodammo round White rod Fire all five of these ammunition types five times and take the average of each. It is preferred that you take videos proving the range, but this is not necessary for you to win the the pro membership. In order to enter your stats, you must have a picture of your gun, AND a picture of the ammo that you used. 2) Build a NAR (no mods please) (only using 2 size #64 bands) and use it to shoot the following ammunition: Finned red rod Red rod Yellow rod Oodammo round White rod Fire all five of these ammunition types five times and take the average of each. It is preferred that you take videos proving the range, but this is not necessary for you to win the the pro membership. In order to enter your stats, you must have a picture of your gun, AND a picture of the ammo that you used.
