Knex bolt action mechanisms?

Could anyone post a link to a bolt action mechanism or gun that doesn't require too many pieces. I have already tried the zkar v2 and the ar-4 but I didn't have enough pieces. I do not have any ball socket pieces and I only have one hinge pair. The ar-4 required too many tan locks. I also do not want to break any pieces. If there is not anything which can help me please post a link to an instructables of good, powerful gun that does not require many pieces, preferably a rifle. Thanks

Concept for Pump + Bolt Action

I had this idea for awhile. Basically you combine the pumping action of a pump and the loading action of a bolt action to get something with a high RoF and high power without needing a turret. The idea is quite simple really. My idea is to have a bolt loading pin attached to a pump that contains the magazine. when you pull the magazine back far enough it will load a round into the chamber. When you move the pump back the bolt pin will push the piece of ammo forward with it. Anyone feel up to making something like this?

How to make a knex gun with a real bolt mechanism?

I am planning to make a new knex gun. This gun is going to have a real 'bolt' which is used to load the next round. It will be pulled back and released which will push the round into the barrel like a real gun. The firing rod will be the same as usual but when firing, as the bullet is further forward would result in the bullet being hit rather than pushed leading to better energy transfer and better firing. I have experimented for a while but cant quite seem to get it to work properly other than the general mech. So if anyone has done anything like this or knows someone who has then please share. Thanks.

DM-15 bolt action sniper

Well, all the great K'nex gunners have snipers(besides oodalumps , but his semi-auto makes up for that :-) ), so I thought i would make one. its nothing really new, nothing innovative. Just that it has a bolt to pull back the ram, that allows for rapid fire. It's could be as powerful as the other snipers but i can't put to much power because i have to pull the ram back with one hand(i am wimpy so you guys will have more power). it has a 9 round mag that could be extended if you wanted. Has a block trigger hooked up to a true trigger. The front is just a make barrel. Bipod folds up and hooks onto the front of the fake barrel. i am sorry that the bolt is hard to see in the gun, it on the right side. only the left side is shown in the first two pics. its in the third pic but is kind of hard to see. it works by having a "door" in the side of the barrel for the bold to travel in and out of. the bolt need tape because the orange connectors would come off instead of pulling back the ram(the ram is the same from the pack sniper). it has just your basic scope on it, nothing to new on that part. yea, i think thats it. instructions are being made.

S2 Bolt Action Pistol Review

When joined Ibles, I knew that I didn't have any guns ready to upload, so, I decided to post some reviews, being that I already had some  guns built. The S2 pistol by  Sharir1701 seemed to be a logical choice, so I grabbed some blue rods did a little bit of testing. Please realize that even though I have just joined the site, I have a wide range of experience with knex guns, such as the ZKAR, TR8, Racker Rifle, and many of Red Book of Westmarch's replicas. In this review I am not going to do the ratings on a scale of one to ten, because Knex guns differ so much. Say you have a gun that shoots 70 feet. You give it a eight out of ten, because that is great range. However, the SRV3 shoots 500 feet, so 70 feet is NOT eight out of ten any more. Due to that, a truly honest review would rate even very nice guns quite low, due to the fact something will probably is better. If you don't understand this, that is OK, because I do, and I am the one writing the review. Also note that this one has Sharir's pin guide holder thingy. Anyway, let's jump right into the review! RANGE:  Frankly, this gun does not live up to Sharir's claim of 100+ feet. I only got 65-70 angled using two size 117 bands, which is still great range for any gun. Sharir says that it will only get that range with three bands. Sometime ago, I used 3 and did not 100 feet. I don't remember what exactly I got with three, but I am sure it didn't get past 75-80 feet. RELIABILITY: This is one of the gun's good points. Knex bolt actions don't have a great reputation for being reliable, but the S2 works nice and smooth. When I decided to review the pistol, I thought it would be nice to test the reliability and give ya'll the numbers. Here they are. I put the gun through two hundred rounds, and it had: 3 failures to fire, 4 failures to load, the pin guide broke twice, the bolt broke once, and the chambering rod popped out of the bolt twice. Now this sounds REALLY bad. However, the pin guide issues, the chambering rod issues and the failures to load were my fault.  The pin guide and chambering rods broke when I was jerking the bolt back too vigorously, and the rounds that wouldn't load were because I was manually  chambering the round, instead of having a return band chamber it. after I added the band, no trouble. ROF: Now this is one part I didn't really test. It charges slower then a ZKAR, but faster then most pin guns. It is good enough for most uses in a Knex war. COMFORT: Pretty comfortable. The handle is quite good, and I think it would be even better for someone with larger hands then mine. The problem is that there is not really a good place for your other hand to go except for the magazine, which doesn't make the best handle. To be truthful, it is kinda awkward to hold. It is too big for a pistol, but doesn't have a stock like a rifle. (Ok, you COULD use the pin guide holder as a stock, but it doesn't work that well) CUT PARTS: The gun is fine when it comes to these. There are several recommend, but you only need one cut gray rod for the chambering rod. ALL IN ALL: This is an awesome gun. not too many pieces,  looks kinda cool, and is fairly accurate. The ammo is blue rods, and i have a couple hundred of those, so it works great for me. Range seems about right, and it is very fun to shoot. In a war it would do pretty good, but the ammo is hard to find in the grass. The mag is a bit small, holding around 13 rods due to the mag pusher taking up quite a bit of space in the mag. This, a TR8, and a ZKAR would make a fine war arsenal.

Vice CKG Bolt Action Rifle

I haven't posted anything for a few months, and I decided to begin work on something that would blow everyone away.  My goal was to create the most efficient, most power, most versatile mag fed knex rifle ever.  I discovered a way to do that when I came up with the Bullet Transfer System (BTS) that you saw in my BTPA pump action rifle.  However, the BTPA had a several drawbacks.  The first was the size of it.  It was just way too big.  Second was that the ammo it shot was connector ammo, and would start spinning out very quickly.  Last was that the ram barely had any time to accelerate,  as the bullet was placed right above the handle.  I suddenly thought of a design that would solve these problems, quickly drew them out, and began work.  The result was the most efficient, versatile, and powerful mag fed gun ever made, the Vice CKG.  CKG stands for Compact Knex Gun, and I am truly proud if it.  The trigger is a variation of Zak's so I give him credit for that.  So exactly how efficient is this gun?  I was able to get 60+ feet with a string of two #64s with the long range round.  The yellow rods get around 50 feet, only because they spin out after a while, but with two #64s unsharpened yellows can go right through a box from a few feet away.  What's the secret to this incredible efficiency?  First off, the firing pin is a grey rod+a gray connector long, giving it that extra room to accelerate.  Second, the trigger is as far back as possible.  Third, the rods are placed as far away from the ram, giving it time to accelerate.  Finally, the BTS allows the bullet to stay in place with nearly no contact between the bullet and the gun.   THIS IS THE MOST POWERFUL, EFFICIENT, AND VERSATILE MAG FED GUN OUT THERE. (I know that statement may sound a little bold, but I am very confident in saying it) Pros 60+ feet range single shot with two #64s 50 feet range with yellows with two #64s Extremely versatile (perfect for long and close range) Looks great 15 yellow rod mag capacity You will dominate the battlefield Cons Reload time (for me anyways)   This video is a little out of date, I have made some upgrades since it was made/

Barackuda Internals

Alright, I grabbed some more internals for the latest version of the Barackuda. I can't believe it's already been over a year since the last time I updated my status update thread. It's sad that nothing much goes on here, but I'll still maintain activity as long as I have ideas. I bought a home in the summer and have since been doing adulty things but I've been looking for more hobbies, so I'm still interested in doing a K'nex gun building guide series for newbies. I otherwise haven't built much. But anyway. For those that don't know, which I imagine are few, the Barackuda (portmanteau of Barack as in Barack Obama and barracuda) is basically a compact bolt action repeater with a small, removable drum magazine. I believe this is the first time a magazine like this has been successfully implemented on a weapon. I spent years figuring out the design and trying to perfect it, never quite satisfied, but I really need to just throw it out there. I'll get full instructions eventually. Hopefully these will do for now. Sorry if some of the pictures ended up sideways. I was using my phone and rushing. Let me know if you'd like any other pictures.

Bolt Action Rotary Magazine Gun (updated with internals)

Alright, it's been a while, forgive me. I work in spurts of an hour or two every few nights. It's not quite finished, but it's at a point I'm comfortable showing. I'm also working with BM, so hopefully he can make some improvements on it before it's posted. This gun is the combination of two different goals I've had. First off, I always wanted to make a bolt action. I came up with the idea for the modern bolt action long ago but was beaten to the punch. So since then, as others have made their own bolt actions, I still struggled to make one up to my own standards. I wanted something sleek and compact with a removable magazine. Second, I went off on a little tangent while building, which then turned into its own project: a rotary magazine. While it's been done before, I don't know if it was ever successfully used in a gun. It's more about the novelty than the practicality, but what it does do is give you more storage in a compact design and act as a decent foregrip. I wanted to make it a decently usable. At first I thought of making just some cruddy gun to show off the concept as a usable magazine, but then I decided I may as well go the full nine yards and make it perform well. So this is what I ended up with. I don't have a real name for it yet, but I've considered calling it the Barackuda, a portmanteau of Barack (Obama) and barracuda because...well why not. I wanted to keep it as compact as possible, so I used a barrel similar to my Oodassault 3 series and a stock connection similar to my PDR. The stock is a bit long compared to the body of the gun, so it may look awkward, but I wanted to give at least enough room to aim the gun without sticking the pin into your eye. The blue connectors in the stock stop the bolt right after the trigger engages. The bolt is somewhat typical. I like how it sits flush with the back of the gun rather than looking like an extension on the back of it. The handle isn't amazing, just a variation of my tried and true handle I've come to like. The trigger also isn't amazing, and in hindsight, I want to block a bit further back still, but it works for the limited space I've got. The magazine on the other hand is magical. Go look at my last topic for details on its operation. This version is for yellow rods. I've added a rotary lock and band. When the middle rod is pushed toward the trigger (like in the pic), it's locked. It can securely contain 10 usable yellow rods while locked, though it can load up to 12, the top 2 can fall out. You insert it into the gun by pressing the top two red rods at an angle into gaps in the grey connectors at the front, then rotate the magazine, slightly pushing in, until you get the white rod in the gaps of the yellow connector. Finally, you push in the middle red rod by the trigger all the way forward to unlock the magazine. Edit (9/10/2015): Made my adjustments and now I'm mostly satisfied with the weapon. Here's the video.

New K'nex ideas and a request.

'Sup people, K'nex.X here, I got something to ask you, does anyone has any ideas for a new K'nex gun? I've practically ran dry and I'd love to have something new to work on. Don't come showing me pictures of models, I'm talking about real innovation like bolt action, lever action and/or semi auto's with a potential range over 30 feet. Next, I got an idea. What if we stop focussing on making models, replicating them as best as we can with the limited forms of k'nex pieces? We could focus on real innovation, the world needs about a 100 more Oblivitus and Kinetic's. Just check it out. Even though most have given up hopes, there are still loads of ideas to improve, perform or make. Take a look at thedunkis' forum topics, Oblivitus' concepts I'ble and Kinetic's mechs. For example, I'm now working on a bullpup, bolt action, horizontal magazine gun. Concepts are far more challenging than replicas. Just try it out for yourself.  Another thing, the veterans left. So stop making a 1001 forum topics about where everybody is, they have left. Mepain, DJRadio, Oodalumps, Zak, Shadowninja31, Coolbas, Killer-safecracker, IamCanadian, KILLERK. They all left. stop complaining, instead of whining, go out there and design something new! The red book of westmarch, Senior waffleman, Drrichtofen and all the awesome new(er) guys. You are the future of K'nex guns! Yours sincerely, Knex.X

Bolt Action, Removable Magazine Slingshot Sniper rifle ( L96 )

Help me guys. Im planning on making a L96 sniper rifle, however the main features have never been on the same gun before. This features are slingshot, bolt action and magazine fed. The idea i had was you pull the rubberband back onto the trigger mech ( maybe something like on Jollex's Dash gun ) then use the bolt to push the bullet from the magazine ( preferably removable ) up in front of the trigger. This means that it would be a repeating slingshot with no friction from the magazine. The main problem would be the bullet staying in front of the trigger but im sure it could be solved. If anyone wants to collaborate your more than welcome :-) Bhuty

The original one had a bottom loading removable mag, shot blue rods 5 feet. I took it apart to make my jackal, and then I got the idea to make it a true bolt action.I was not trying to compete with the ZKAR, I was just trying to make my AR-4 v3 work.Here is a video of me firing it on youtube:

What i've been up to: the bolt action, bullpup, tube mag, pump action, dual shot, sling repeater. Got your attention yet?

Ok, for those of you who had seen my shotgun design, you could probably tell it was over before it had even started.  I had tried 5 different layouts and I couldn't get past the frontmost barrel without running into problems.  I think it was a cool design, but it was just too much for K'nex. Most of my best get designs just pop into my head at the most random times.  Is it just me, or does this happen to other people too?  Anyways I was trying to make it until the bell in pre-cal (my teacher is a crazy cat woman who enjoys talking about her imaginary husband) and I just started drawing this design.  Not only did it kill 10 minutes but it may just be the best thing I've come up with in terms of K'nex. The magazine looking thing in front of the handle is actually the driving mechanism in this gun.  Shots are housed in the stock pressing up against the pusher.  When the pump is pulled, the pusher moves down, allowing two bullets (one shot) into the chamber.  When the pump is released, the pusher pushes the bullets up against an upper section, where they wait for the trigger so be pulled, releasing the ratchet and the rubber band, launching the two bullets with a decent (I hope) spread.   Even though it doesn't shoot yet it is fun to just load the ammo (thats just how cool this gun it).  It is probably going to be a little different than what is shown in the video by the time I post it, but right now I'm just going with what I have.  I hope you like it and please let me know of any improvements you can come up with. -Kinetic

knex firing mechanism thingy

I didnt look around much so this may be old news... you can just delete this if it is the idea is that when you pull back and a little up the bolt pops out of the barrel and rests against the front of the chamber, until you push down on the hammer, which puts the bolt back in the barrel again :P if you make it with reds or grays they bend a bit much but it still works the problem is that theres no real way to make it bolt-action

I have 4 guns, which one should I create an instructable for?

Alright, I'm not new to knex guns, I've been making them for a good 2 years. However, I AM new to making instructables for my own guns. Now, I have a list of 4 guns I have made, let me describe them so the community can choose which one I should make: 1. SSAP : A Standard Semi Automatic Pistol that I designed to look like a real pistol. While it doesnt look similar to any one real firearm, i does look like a real pistol. It is TRUELY semi automatic, I have designed it to be easy to use, and easy going on the fingers. Many semi automatic guns can be a pain to constantly push around the trigger, but not this one. It has a hidden magazine that holds 3 green rods. Now, since it is a semi automatic pistol it doesnt shoot as far as other single action guns. 2. SBAR : A Standard Bolt Action Rifle that holds 6 blue rods. It is an extremely sturdy and reliable, the magazine almost never jams. WITH the detachable barell it shoots about 30 feert, however you can easily get rid of the barrel and have it shoot even further, however I keep the barrel for cosmetics. It is my personal favorite of my creations and I am yet to take it apart for any other gun I see on instructables. 3. Desert Eagle Semi Automatic Pistol This is my most recent gun, I never actually meant for it to look like a desert eagle, however in the middle of construction I realised the resemblance and decided to make it a replica of the desert eagle. It is like my first semi auto pistol, however it holds 5 shots, is MUCH bigger and shoots white rods instead of green rods, which I suspect increases the distance. However if you have small hands (like me) it may feel slightly uncomfortable so I advise building the smaller SSAP above. It has the most resemblance to a desert eagle than all the other pistols I've seen on instructables (Believe me, I searched "Knex Desert Eagle) Remember, this also has a hidden magasine and is semi auto so it doesnt shoot that far compared to other guns. So guys, please respond and ask me to post an instructable for one. I look forward to being a part of the knex weapon community :).

How to make the best gun in the universe even better.

Sorry for the extremely braggy title, I just needed something to grab attention, because these mods are MANDATORY. I have made some mods to the bolt, ram and barrel that are required for my AR-4 v3 Picture 1- Ram mod.  Add these spacers in there.  This keeps the ram from breaking the bolt when you fire. Picture 2- Bolt mod.  I change the number of 1- slot connectors that hold the bolt from 2 to 3.  I also mod the ram so that the part that goes before the bolt is 1 orange connector, and 2 blue caps. Picture 3- 2 barrel mods.  There is a third mod, but I will go ahead and explain this first.  The top of the barrel is changed a little bit.  Note it.   The second barrel mod was actually made by makers of my AR-4 v3.  It required  me to remove the white connector from the front of the barrel.  This somehow increases the power to a staggering 45 feet with 1 rubberband, around 70 with 3 (doubled up), making this the most powerful bolt action gun ever posted. Picture 4- Bullet lock mod.  Sorry for the crappy picture, but it has too much shadow.  Anyways, where the new ram sticks out, you place the ball joint socket.  This also increases the power, and gives you the ability to point it down. With all the mods I made, you can load and fire the gun sideways.

Charging Handle Bullet Chambering System Concept

Bolt action is going to be too specific to describe the action of loading a bullet in such a way as to increase power so I'm just going to call it chambering. Bolt action chambering was done through the use of two separate pins and "barrels". The magazine loaded ammo into a separate area and then was pushed into the barrel by the bolt pin. This works pretty well but it's a little complicated and some potential accelerating space is wasted with the bolt. I wanted to simplify the action of chambering a round for max power. Why not just have one barrel?  I made a powerpoint to demonstrate the concept. There are still a few problems I need to figure out before I can work on such a gun such as how the trigger would work and how to keep the ammo in the magazine down. I have ideas for both but nothing that I'm 100% sure of. If anyone would like to try this concept out, PM me. You can download the powerpoint here. (make sure you play through it, don't just scroll through the slides)

Auto-chambering Repeater Concept

I just got this idea a couple days ago talking to Jammy. Here's a crash course physics lesson: When a larger object (a pin in this case) hits a smaller object (ammo in this case), only enough energy to make the ammo fly faster is transferred. This is because it takes less energy to make something of less mass move at the same speed as something with more mass. So as soon as enough energy is lost in the pin and gained in the ammo, they fall out of contact and the rest of the energy in the pin is wasted. You can't really make pins any more efficient than they already are, so I figured I'd try utilizing the otherwise wasted energy. I figured one of the ways you could do this is by making a gun that automatically chambers a round after being fired. It'd be like a bolt action weapon except instead of manually operating a bolt handle, the extra energy would load the the round for you. The result is less effort and more efficient pin use. People may think this is less reliable than manually operating the bolt bin, but I beg to differ. This, in theory, would provide a more consistent chambering action. As long as it's fine tuned, the rounds should load exactly the same each shot. Also, you wouldn't be able to screw up chambering an extra round. You can pull the bolt handle back on a cocked bolt action weapon and easily jam the mechanism. With my concept, you can only chamber a round after the currently chambered one is fired (unless you purposely fiddle with the back of the gun) because the bolt pin relies on the firing pin to operate. I have the front of this gun finished, but I still need to design the bolt pin assembly and the back of the gun to hold it so that I can actually fire this thing, but I'm confident it'll work out very well once I do. Here's a video to demonstrate the concept. I'm hoping that once this gun is finished, it'll be a viable war weapon, seeing how I don't have anything better than my Oodassault at the moment. Or at least if I can't finish mine, someone else can use the concept.

Tesla Music at the Maker Faire!

So today I got a sneek peek of the Maker Faire at Young Maker's Day. And with it, something that simply blew me away. This tesla coil demo uses two TALL towers with lightning bolts coming out the top. The lightning bolts are what make the music! And the drums are robotic! That's what's waiting for all who are coming over the weekend. Enjoy! I included a video. Young Maker Day: Amazing Tesla Coil Music! @ Yahoo! Video
