Picture of K'nex Concepts
This instructable is to show k'nex ideas so that others can try to build them. They are going to be mostly weapon ideas.


Step 1- Ammo Feeding
Step 2- Triggers
Step 3- Barrels
Step 4- Firing Pins & Pulls
Step 5- Grenades
Step 6- Guns
Step 7- Miscellaneous Weapon Designs
Step 8- Miscellaneous Non Weapon Designs
Step 9- Real Life Weapon Designs
Step 10- Concepts In Progress
Step 11- Stuff That's Been Done
Step 12- Completed concepts

If you have any questions, would like a more detailed explaination or more pictures for a peticular design please ask.

Each picture corresponds to a letter and 2 numbers, the first letter is the section, the first number is the picture number, and the second number is the design number.

Similarity to any other design is coincidental. If you use any of the ideas from Knex Concepts, you must give the designer credit for their idea on the intro step of your instructables and slideshows.

Tell me if you post an instructable using one of these concepts, if you successfully construct one of the concepts, I will rate an instructable including it five stars.


Step 1: Ammo Feeding

1A1: Staircase Hopper: This hopper uses 90 degree angles instead of a funnel so that ammo cannot jam. -by Oblivitus (credit to cj81499 for the visual)
2A2: Hopper Revolver: This design uses 8 straight line hoppers (which are jam free) on a revolver to conserve vertical space. -by Oblivitus
3A3: Horizontal Magazine: This mag stores ammo in a line parallel to the barrel and turns it up through a curve into the chamber for firing. -by Oblivitus
4A4: Auto Feed Magazine: This is a new mechanism that will release a loaded mag upon inserting it into the gun. This picture shows the magazine before insertion. The green lines in the picture are elastic bands. Read the note. -by Oblivitus
5A4: Auto Feed Magazine: This picture shows the magazine after it has been inserted. Read the note. -by Oblivitus
6A5: Non-Interlock Magazine: This magazine feeds one round into the chamber at a time to prevent the grooves in rods from locking together. Interlocking k'nex rods reduce power so this magazine will be more powerful than others. -by Oblivitus
7A6: Detachable Mag Handle: A pistol with a detachable handle that is also a magazine. -by Oblivitus
8A7: Thin High Caliber Mag: A blue rod magazine instead holds yellow rods at an angle to save space. -by Oblivitus
9A8: Tilted Horizontal Mag: Rounds would be pushed along by an angled mag pusher. This design saves space and therefore increases capacity. -by Oblivitus
10A9: KKAR: KillerK's new ammo magazine. This magazine allows lots of ammo in a small space, and was inspired by the Peacemaker Carbine from Bulletstorm. -by TheFoofinator
11A10: Spiral Drum Mag: Drum mag with two rods that rotate in one direction to push rounds to the outside of the spiral and into a firing chamber. -by Oblivitus
11A11: Layered Drum Mag: A drum mag with multiple layers that fill the entire space within the drum which both rotates with an elastic and is pushed up by an elastic. When the outer layer is emptied of rounds, the drum moves up and the next layer begins emptying. This layer changing would be achieved by making the rounds press upward against a flat surface on the gun. -by Oblivitus

Might as well mark me down as all of them. I could have built any one i wanted, i just deemed some not innovative enough to WOW people. :) just concentrated on the aweome ones.

Yo i gotta say tho, i would have never even tried if it weren't for you. Thanks
Oblivitus (author)  KnexFreek4 years ago
Thanks. I'm just glad someone took to my ideas. It's surprisingly satisfying for me to see my them made real, even more than if I made them myself (maybe because I'm not self critical of them). And I enjoy coming up with things.

Would have never even tried? Do you mean to say that if you hadn't seen my ideas, you wouldn't have gotten into knex guns? If so, that's a great compliment and I thank you.

horizontal mag: COMPLETED.
Oblivitus (author)  CODawesome2 years ago
And it will be used on my pp-19 which iwill make soon. But the mag is really good, only with minor flaws
Oblivitus (author)  CODawesome2 years ago
Oh sweet.
that might work!
CODawesome3 years ago
It took me 2 weeks for making a spiral drum mag, And I tried every possible way. Trust me, it is IMPOSSIBLE to make it out of knex.
I have a drum mag right now....
Drew99-KGB3 years ago
I got mag thing number to done. The one with 8 mags on the spinning thing like a revolver. Mine only has 4. I couldn't make 8 because where the 5th, 6th, 7th, and 8th mags would be, I had to put something to keep the bullet in place to solve a jamming issue. Each one can hold 15 bullets but I only put 12 in at a time to solve another jamming problem. All together mine has 48 rounds in it.
Oblivitus (author)  Drew99-KGB3 years ago
Cool. It'd be great to see that on a gun.
lol "Hint! Hint!" I will put it on a gun and post but right now working on a machine gun so I had to take it apart but don't worry I took lots of pictures of it first so I can rebuild. I could put it on my machine gun but I would rather not right now. Maybe later as like an extra mod option.
LiftAndLove3 years ago
AWESOME. I have a question. Were did you get all these Knex? I really want some, but am really low on money.
Oblivitus (author)  LiftAndLove3 years ago
Ebay. Search "pounds of knex" and sort by lowest price first.
I believe that this would be the most efficient way to build a knex bow!
GASSYPOOTS3 years ago
uhh dude your 8 barreled gun is mased off of my 3 barreled gun
Oblivitus (author)  GASSYPOOTS3 years ago
That's assuming heard of it. I haven't. Perhaps they're similar, but I haven't seen it. Would you mind giving me a link to it?
Here's my semi auto concept, but it needs to be geared up. I wanted to know if you think it would work?
Full auto Knex.png
Oblivitus (author)  KnexFreak3603 years ago
Oh it can definitely work. It's getting enough power to fire it with a lot of range that's difficult.
Also if you have any suggestions please let me know that would be very helpful!
Oblivitus (author)  KnexFreak3603 years ago
You'll need a lot of motors or at least a few of the powerful ones to be able to get decent range with this. You will most likely need to make a few or several versions of it or even change the design entirely to reach it's max potential. My advice is to persevere and not stop working until you've completely exhausted all possibilities. When you approach a project this way you will either create greatness or double your knowledge in your failure. You can't lose.
Ok thanks, do you think 2 of they large gray motors will be fine?
Oblivitus (author)  KnexFreak3603 years ago
Maybe. I've never had one before and I don't know how much power this gun will need to work well but I do know it'll need all the power you can get. You may also want to consider an elastic coil like the one on my SA 3252. That's another way to get lots of power, but has a very limited number of rotations and is mechanically complicated as well as complex in its physics.
Yea, i have the motors now all I need are some gears.
dmytro5093 years ago
ill use the third mec i think that the gun i make will be very revolutionary for knex builders
rofl4955 years ago
you should add this pic for the rear sights
didexo rofl4953 years ago
I made the double mag its posted check it out
~KnexBuild~3 years ago
Would the Non-Interlock Magazine work?
Oblivitus (author)  ~KnexBuild~3 years ago
Someone tried making it once but it didn't increase range or power in their version of it. The concept is theoretical. I can't guarantee you'll get results.
On what gun was it used?
Oblivitus (author)  ~KnexBuild~3 years ago
You can find it on the last step.
JJ80903 years ago
I hope you dont mind (though i know you wont) if i use the hopper revolver thingy?
it will be my first gun so i intend it to b good :)
Oblivitus (author)  JJ80903 years ago
I want people to use these ideas, that's why I posted them. Just give me credit by mentioning my name and which of my ideas that you used. Thanks. :)
cazadactle3 years ago
The tilted idea didn't work when I tried it on my pistol (it doesn't load properly into the chamber). Also although I think these are extremely good ideas i'm not sure that youwould be able to fit these pieces that they use into a compact gun (for instance the auto feed mag would be very hard to make into a compact design :( ).
But still, it all looks great though!!!
well after going through some different ibles and here i haven't found something that can fuel my new gun D: it is a brand new style but i need a way to have a set of gears turn for the ammo to get to the point of firing it all i have is a tr spinning design and i need about 2-3 times that of a tr spiner thing. i have tried i huge sling with a semi auto mech on it to spin it but it was to much and the ammo got messed up. any ideas?
I'm not sure what you mean. More explanation with drawings would help.
well as i try to draw this this is basicly the best i can get. i have a gun with a turning mech like on the TR guns that rotate the turret but for me it rotates gears on that rod to feed ammo into place to fire a motor cant be used because the rod the gears are on needs to stop once the ammo is in place and then move when it is fired to the next one also the TR style of rotating dose not produce enought torque to move the ammo into place.
Okay, I understand what you're doing now. I'm still not sure if I can come up with a solution without seeing something, but I'll throw out an idea. Do you think an elastic spool would work? (a wheel or wheel shaped construct that an elastic can be wound around to get rotating force)
well i just tried a mech that is 2 white cons with 4 white rods on it and a rubber band hooked to a white rod and the bands go above and wrap around a bit but it dosent like to wrap to well
wabawaba3 years ago
Omg I just hatched the greatest idea, what if there was a type of vertical slide and u had a bunch of knex guns like in a circle or on a belt, and to pull back the pins everytime it makes a round around the the vertical slide pushes the pins at the end of the slide it ends going back up and the gun on the belt shoots. I'l try to get some pics I think it would make a powerful full auto
verypoopy4 years ago
Here it is.
knex shotgun mech.bmp
Oblivitus (author)  verypoopy4 years ago
Cool. Do you mind if I add this to the instructable?
Nope that's fine if you put it up
verypoopy4 years ago
I'd like to see mech #3 (Horizontal Mag) turned into a pump action shotgun. I've made something similar in a mech where you load the shotgun shells in like a real gun and they are held in by a door release with pressure on them to go out of the mag with rubber bands. Then, when you pump it, it catches one of the bullets while cocking the ram back, shooting one of the bullets. I couldn't get the pump to catch the bullets to go into the barrel though, so i'm wondering if anyone could help. Here's a pic.
Holmes1014 years ago
wow u r a genius
Oblivitus (author)  Holmes1014 years ago
Thank you very much. I see you're new here. Well, if you're going to make your own knex guns, you're in the right place. Lots of ideas here. Some of them may be easy enough for a beginner. But if you're looking for a good first gun, my UP3 is worth taking a look at; http://www.instructables.com/id/UP3-Knex-Pistol/ My instructions are easy to follow on this one and it's a pretty easy build. Gets 50 feet of range.
Polarize4 years ago
Hey, i recently had this concept for a semi automatic slingshot. I realize that slingshots are already semi/fully automatic, but this idea is for one that fires every time you pull the trigger. It could also probably shoot multiple burst rounds with no reloading.

Anyway unfortunately i don't have enough pieces to finish it, and it didn't seem worthy of an instructable, so i thought this would be a good place to put it. If someone could make this idea into a real gun i would be happy :)

It uses my RBG i made years ago on another account http://www.instructables.com/id/Semi-auto-rbg-pistol/

Here are some picture of it. Basically when you pull the trigger, the cogs turn, and push up the mechanism at the back, pushing the oodammo off like an ordinary slingshot. (btw, i actually was the first to ever post a gun using oodammo, check bunduks account ;) still oodalumps has the credit for realizing its great potential :P) The mechanism moves up a few places at a time, thus putting burst fire into the picture.

Oblivitus (author)  Polarize4 years ago
Cool. A lot of people have thought of similar designs. The semi-auto mech is a nice twist on it though.
Seleziona5 years ago
Slide action slingshot is VERY hard to make :(
Haha.. You replied almost a year later!
Oblivitus (author)  KnexFreek4 years ago
It is called a tank bow upside down.
Oblivitus (author)  Seleziona5 years ago
kNeXFreek already made it. His pump action guns use my system.
Oh, but i tried to make it SLIDE action, but it was way too hard..
I love your instructable Oblivitus. The only problem is that I can't build anything cause I have like 100 pieces and only 4 are snowflake connectors. If anyone knows a good weapon that I can probably build with these pieces :( please tell me. I would appreciate it. I will try to design something with your concepts when my mom buys pieces for me... She thinks Knex is too childish.
Go to http://www.knexusergroup.org.uk/acatalog/knex-parts-connectors.html

You can get snowflake connectors for around 20p-30p ($0.32 - $0.48
Go to knex user group


choose your country on the left and shop you get parts really cheap
Oblivitus (author)  ThisChessPlayer5 years ago
Knex childish? I'm 19. Well, anyway, here is one tiny gun; http://www.instructables.com/id/Smallest-True-Trigger-Mag-Fed-Knex-Gun-El-Mosq/
well that's my mom's view... i'm good at building stuff and i like knex because it's stable...if i use tape and random parts... it never goes 20+ now i've showed her instructables and she thinks it's now a waste of time. she might get me knex but no guarantees :(
dont go to walmart, most of the pieces are micros, order at knex.com or ebay either one is good, knex.com has all the pieces, but sometimes theyll be out of stock, but they give you the choice of pieces and the quantity, and you get free grab bags after $25, and when they are out of stock, go on ebay, pretty cheap for high amount of pieces =)
I will sell you pieces or a complete gun if you want.
no thx. i can buy them from like walmart according to someone else...
Yes but It will be around 20 dollars for 400 pieces but half of them are micro knex so you would be saving money.
5* and can someone show me how something that shoots 50+ ft works? Diagram please. Thanks guys ._.
rofl4955 years ago
I had an idea for a gun with a rectangle barrel with a gap in the middle so it would be like two rails close enough so that the ammo wont fall out and this would guide the ammo as it is shot by a rubber band going behind the ammo which would be an orange/gray connector.It would be as powerful as a slingshot but more compact and it could be made into a repeater.
You're suggesting using friction to keep the ammo in the correct firing path. If you got this much friction then the ammo wouldn't move.
hey there i was thinking of 2 guns into 1 gun (NAR and your shotguns) and i tried it it didnt work to well so i figured id post it here i see if someone else can make it better
Yeah, I think that the problem with that is that the 3 shot barrel requires a longer striking area because the rods are held so snugly. Try another type of magazine/chamber. I'm assuming that the problem with yours is poor range?
yeh i got like 5ft
Would someone be intersted in a colaboration? An inovative knex gun?
Yes, if you don't mind me only assisting you with computer models and drawings.
I dont mind.
Sketch985 years ago
how would you keep the bottom bullet from falling out of the hoppers in 2A2
Oblivitus (author)  Sketch985 years ago
A cover.
then how does the bullet get out
It goes into the center, not the outside, so closing it on the outside is a very good idea.
Sketch985 years ago
For the weighted auto i made something similar except it turned the gears using a cylinder wrapped tightly with a super long rubber band that was attached to the back and releasing the trigger made it spin super fast to pull back the ram.
Oblivitus (author)  Sketch985 years ago
Yeah, I tried the same thing before.
Sketch985 years ago
for the Bouncing Betty make it push a grenade with a pin up and when it gets high enough the pin is pulled out. The only problem is the grenade has to explode with out force.
attach the pin to the bottom of the container with string or fishing line.
Smasher5555 years ago
I am building a rifle now with prodo123's SR-70A1 PSRS stock and body, but a completely different barrel. The rear barrel is similar:)
does the spinning barrel really work, and could you use it with the finned ammo for a sniper rifle?
Oblivitus (author)  naruto the ninja135 years ago
It's not likely to work, it's probably impossible.
you need to add my sniper rifle, it includes concept 6A5, so yea
supah4x0r5 years ago
hey good ideas i like the grenade idea i can see how that would work so keep up the good work.

ant ant 335 years ago
 I think if someone could fully understand the elastics reset mech then it would be a total breakthrough. ( i dont get it! too much for my tiny mind to contemplate:L)

Oblivitus (author)  ant ant 335 years ago
Are you referring to the weight powered mg?
Horizontal mag gun looks great, but one question, how would the mech work if the mag was in the way? Unless an external blocking mech is used, I see no way the mech could be internal without being exceedingly fat. Unless the mag was to one side and the mech was in the middle.
 I also like the high powered shotty. Im assuming that the pump will work by string, so cant you bend the string with rods so that you will have increased space and the ability to put the firing area inside the gun?
Oblivitus (author)  Soopah Steve5 years ago
You could and should with a mag fed design, but I drew it with a revolver, which is more practical on the outside.
Oblivitus (author)  Soopah Steve5 years ago
I would use an external trigger mech.
I am also wondering how this works... can u send me that video too?
cj814995 years ago
i have better pic for 1A1 ill post if u want
Oblivitus (author)  cj814995 years ago
Yeah, go ahead.
Oblivitus (author)  cj814995 years ago
Nice, how did you make that diagram? Please print it out and take a picture of it though, it's warped from the computer screen.
i will but i cant right now i am at my grandma and grandpa's house but when i get back i will i made it on word
cj81499 cj814995 years ago
here we go
Oblivitus (author)  cj814995 years ago
Sorry, but I just removed that because I noticed it's incorrect.
Whats wrong with it?
Nevermind. I figured it out.

Is it because the ram would be hitting the side of the yellow rods?
Your drawing is showing the ammo as like balls. If they were rods, when the ram hits the firing shot, its would leave the barrel sideways.
ooh i get it
Oblivitus (author)  cj814995 years ago
"bump" look down
What do you plan to do with the eight that are on the sides? You won't be able to fire those; they will try to go to the middle at the same time and cause a jam.
hey all i did was make a pic
hey all i did was tell u wot was rong with teh pic.

Why don't you use proper grammar? The internet is a series of tubes, but it doesn't cost you money for longer posts like it does with text messages.

 add the tankbow to step 11 and the freekiller!
Oblivitus (author)  KnexFreek5 years ago
I will only add them if you give me some degree of credit on the intro step of the instructables. I just checked and didn't see any.
KnexFreek5 years ago
 can you add all of instructables to this list??? LOL
Also, if not, just add a link to my page :) LOL!!!

(this is on step 11)
Oblivitus (author)  KnexFreek5 years ago
I'll add anything that you give me credit for on the instructable.
Whaleman6 years ago
1A1 will not work well, unless you can find a way to magically get the rods to go down to the center (that's why they are a funnel shaped).

3A3 has been done before. http://knexinnovation.net/forums/viewtopic.php?f=2&t=782

2A2 was (I think) going to be on Mepain's gatling gun (from way back).
can u redo the link under this comment it doesn't work.
Maybe. That comment was almost a year old and KI has been moved to vBulletin. That's why the links don't work. The point isn't to show you a completed model with instructions that used the method, but to show you that there are people who actually made or are making prototypes, instead of just posting an idea thread so that you can claim the idea as your own.

I couldn't find the original topic, having not retained for the last eight months the poster, post date, post name, or the forum it was posted in.
Oblivitus (author)  Whaleman6 years ago
A1 will work because gravity will still drop rounds in when there are several shots in the hopper because the bottom row will refill itself and thus one round will continue to fall in for every one fired, when the bottom row begins to deplete a slight tilt or a shake (the forecoil from the gun firing for example) will knock the ammo in. A3 was posted by TheDunkis after I posted my idea on this instructable. As far as I know, A2 has never been posted.
You can beat the crap out of me but i still won't know Dutch and not Einstein
Oblivitus (author)  Whaleman6 years ago
I have added some more ideas recently, take a look if you like.
i had an attept at the 1A1 hopper and alot of ammo got stuck on the sides also i tried a similar one and still faced same problems also it does frequently jam...ver good ideas
Oblivitus (author)  knexmaniac1096 years ago
Well, Tiger Nod and DJ Radio said it has already been done, but I just decided to keep it on here anyway because I didn't know about so I'm sure there are a lot of other people who didn't either.
If you us 45 degree angles and not 90 degree angles you could get every last one
cj814995 years ago
can i have a link to make a tilted horizontal mag if it has been done?
Oblivitus (author)  cj814995 years ago
I can't find it. The link below doesn't work either.

do you mind if i build some ideas of yours?
Oblivitus (author)  smattman225 years ago
Feel free to use any of them, that's why they're on here. Read my conditions on the intro step first though. I ask that you give me credit on the intro step of all instructables and slideshows that you post with one of my ideas.
I build the short barrel to short barrel on hinge thing. I'll post it in a min

nickpkcin5 years ago
I have another idea, for making extremely powerful guns, where rubber bands would help pull back the ram rod but release it when you pull the trigger, allowing the gun to have more power.
Knexwizard5 years ago
has anyone noticed that the related choices and stuff is on the left side now. Or is it just me. i do not like it.

the third design is what shotguns use, isnt,it?

Yeah, I think it's pretty similar.
knexfreak955 years ago
 hey what happened to my rod thingy
Oblivitus (author)  knexfreak955 years ago
I moved it to miscellaneous weapon designs.
 ok hey is my shotgun system or whate ever worth it
yerjoking5 years ago
I did the side by side magazine thing a while ago, only you don't need one to face down, it's much easier to pull the mag out, move it to the left/right a few inches then insert the fresh mag.
Oblivitus (author)  yerjoking5 years ago
Huh, I didn't think of that, this is the type that is supposedly used on a real gun though, a friend told me about it.
Yup. Alot of airsoft magazines (G36C is the only one I've seen but surely it's not the only one) can be stacked side by side aswell.
my mp5 has a mag like that
is it the aftermath broxa one?
No i dont buy aftermath gun they dont last long and suck alot
[Nerds get crazy when they have something in common]

Oblivitus: my aforesaid shotgun's magazine may be used in the aforesaid fashion. simply move it to the side. quite simple, really.

kNeXFreek & silentassasin21, respectively: My cousin and I have airsoft rifles that use the same magazines, so we can trade ammo whenever we want!
no way!!!! just like my friends!!! does yours have a fake bullet atthe top of the mag too?
yeah it slides toward me to put extra ammo in

knex mad5 years ago
ok so the pictures for the detachable mag handle gun is here because instructables wont let me post pictures in a comment please check them out

Oblivitus (author)  knex mad5 years ago
Good job, so can you hold it by the handle (without it getting ripped off of the gun) while you're cocking and firing it?
yep it worked good
Oblivitus (author)  knex mad5 years ago
Great, make sure to post it, I'll add it to my Knex Concepts group, give you a five star rating, and put it on the completed concepts step. You just need to give me credit for the idea somewhere in the intro to the instructable.

also please check out my new gun its a lancer from gears of war

Kinetic5 years ago
Hey oblivitus-this has to be my greatest idea yet, as it can be incorperated into several into several types of guns.  When this is finished, I will make it into a slide action sling rifle, but without the removable mag.  Let me know what you think.

Oblivitus (author)  Kinetic5 years ago
Well now you're just advertising, but I don't care, more comments for my instructable. XD
Post pictures that is awesome.

stale565 years ago
I have a random idea for a drum mag.
basically, it is 2 large yellow wheels and a chain around them.
and on the chain, is a turret that fits into the barrel.
Random, yes.
Possible, maybe.
I don't have any of the large yellow wheels, so I can't try it.
Hey! i thought of that!

Curses! dIDN'T EVER POST IT...

EDIT: Sorry, I thought I posted this in the sharing thread you posted, sorry.

I'm moving it now.

knex mad5 years ago

i have made step 1 7a6

detachable mag handle a put up a pic for you as soon as i can

Oblivitus (author)  knex mad5 years ago
Great, I'll be looking forward to it.
Oblivitus (author) 5 years ago
I read this on Wikipedia:

"More recently "double drum" designs have come into greater use. Where normal magazines put rounds in two rows, in a "double drum" two drums resting on either side of the weapon each hold one row, the two of which combine into one row before entering the receiver. Examples are the World War II era MG 15, and the modern Beta C-Mag."

If someone can find how the magazines are combined then it could be adapted to knex. If anyone figures it out please post a drawing/picture and description of the design in a comment.
Late reply I know but I made a dual stacked magazine for shelled ammo at one point. It wasn't too practical but I think I know how the dual drum concept works. It's just like a faro shuffle. The bullets weave themselves together into one stack by alternating which drum feeds a round into the stack. Pretty simple actually. I tried making a straight magazine with two separate sides that would join into one but it's rather hard to get them both to feed reliably into one stack. That was some time ago though so I may be able to make something better.
Oblivitus (author)  TheDunkis5 years ago
Okay, that's simpler than I thought. So they probably held the rounds in a staggered line then? I'm guessing, but is that the trick to it? I tried making a dual mag a while ago too.
Basically it is just 2 'snail' magazines that feed the ammunition along the rectangular 'box' sections of each magazines, then once the magazines end the cartridges are forced against a ramp - turning the feed direction from horizontal to vertically downwards. Now there is now no barrier between the two lines of ammunition so they converge in to one stream which is then fed into the gun.
Thank you, but I still want to know more about how they converge.

That's what I said. I posted a hop up on the Z35 instructable today. Check it out.

methinks i shall have a go at the 4th and 5th ones
Oblivitus (author)  finmonster5 years ago
The biggest challenge with that one is making it small enough to be practical. Good luck.
finmonster5 years ago
hiyadudez has already done a version of this
Oblivitus (author)  finmonster5 years ago
Link please?
it is by lowney sry and its not in the barrel o well u will see www.instructables.com/id/True-Rifle-The-Tempest/
Oblivitus (author)  finmonster5 years ago
Yes, I saw Lowneys already. From looking at it and even after watching the video, I don't believe that it actually works however.

May I add to the completed concepts, with my RAWR? Technically, it was an independent Mag Stock and was published (as a slideshow, but still) before the KAST-R3.
Oblivitus (author)  Raikou-san5 years ago
Yeah, I'll add it. If you don't give me credit because it was independently thought of, I don't rate five stars and I add an *independent* tag to your guns name.
Sounds reasonable to me. :)
yerjoking5 years ago
That MG 315 I think it was called.

I had the same idea nearly, only mine was 10 block triggers in a sort of mag strike configuration (Y'know, the nerf gun) the trigger released the block of block triggers, elastics pulled them upwards, adjusting the elastics gave slower or higher ROF.

Was too fiddly for me to get one shooting/working but I reckon someone else could do it.
scott86925 years ago
i got the horizontal mag to work i just need to work out the kinks and jams of it out
Oblivitus (author)  scott86925 years ago
Cool, unfortunately, TheDunkis made one a few months ago and posted it on knexinnovation.net, but he didn't get the idea from me.
well soon instructable.com will have one .........i believe there will be rejoicing
(i think i spelled that right)

The Jamalam5 years ago
Made a breakthrough!
I'm releasing a small group for an assault kit, comprising:
TJASTR2 (The Jamalam's Assault rifle V2)
TJSAS2 (The Jamalam's Slide action Slingshot V2) (Yup!)
TJTS (The Jamalam's Tactical shotgun)(In production)

The new slide takes the rubberband back and then deposits it directly behind the ammo, behind and blocked by a standard true trigger. When pulled, the trigger is no longer blocking the ammo, and so the rubberband fires forward and is caught on the slide, while the ammo carries on. Won't reveal my new mech until it's posted ;)
You beat me to it.

You shoud try addding a pump to it, and then have it connected to the slide. If you haven't already.

But good job, I can't wait to see it.
Oblivitus (author)  The Jamalam5 years ago
Nice!, do I get any credit? :)
Of course ;)
Hit a little snag, need to work things out but I know what to do! Working on it as we speak (or I type...).
Oblivitus (author)  The Jamalam5 years ago
All right, I look forward to seeing the finished gun.
Lowney5 years ago
Would this count? It's not got a mag stock, and it's only an optional extra but meh. It uses one of my own concpets for the monopod: a ratchet!
Oblivitus (author)  Lowney5 years ago
Nice, and yes?, if you want to call that my idea, then you can give me credit? Is that what you meant?
Well, it's kinda like a fusion of your's and DJ Radio's (the omen)
cj814995 years ago
4 shot barel is cool but they cant be on top of each other uless one mag pusher came from the top or side
Oblivitus (author)  cj814995 years ago
It's possible, they can be on top of each other, magazines or no magazines. It would use two triggers, each would fire two barrels.
KnexFreek5 years ago
whenya gonna post mods to my gun? Just wondrin, no rush
Oblivitus (author)  KnexFreek5 years ago
I'll be making an instructable for it after I post the Ultra Pistol 2.
 ok :) cant wait to see the new pistol! whats the range???????????
can it shoot through a can with a unsharpened rod
Oblivitus (author)  KnexFreek5 years ago
It has the same stats as the first ultra pistol, which uses the same firing setup as the DD-27 assault rifle, so it has the same power and range. I have never tried shooting at a can close up, but it shoots through some thin cardboard with only a yellow unsharpened rod, it can fire gray rods to do more damage as well. The improvements aren't to its range or power however, it now has a shorter barrel, as I found the old one was unnecesarily long, allowing for a greater variety of ammunition, it is much easier and more foolproof to use, making it faster to reload, more structurally strong, preventing any parts from breaking off and allowing for one hand cocking even with large amounts of elastics, and is overall more reliable. It's excellent reliability, versatility, and high rate of fire are what makes it the best of its kind.
Oblivitus (author)  KnexFreek5 years ago
I am making a slideshow for it right now.
Oblivitus (author)  KnexFreek5 years ago
I don't know, I may even make an instructable for it. I'll post a slideshow in any case though.
I have made a rather "crappy" double-barreled shotgun before this post. I wonder if I am the first?

Anyway, enjoy the pain:

Note: I'm no noob, and yes I have common sense. Don't flame me for the above. I'm not claiming anything...

 I'm working on a semi-automatic real pistol (1 handle
Oblivitus (author)  Merugop5 years ago
I tried doing that with tiny gears before, the mech wouldn't hold under pressure though.
My pistol already shoots (is that done before 1 handled pistol within the handle a mag and true trigger  the only thing i need to do is change the trigger and then its semi-auto but it only shoots 40 feet

 It wasn't that great after you shot 1 time the loaded bullet jammed and it was ugly in the vacation i make a new one i think
Lowney5 years ago
It's not a mag holder, but it's the same concept (over 50 rods can be held):
Oblivitus (author)  Lowney5 years ago
Cool, thanks for showing us.
Me thinks it looks ugly. I'll probably use the idea for my assault rifle (I guess you could call it competition :P)
knex_mepalm5 years ago
I am going to try this grenade IDEA! It will be new, Ive got it thout upin my head, now how do I do it. Will you promise not to insult me if itdoes not end up EXACTLY like how you want it.
Oblivitus (author)  knex_mepalm5 years ago
Yes, go ahead.
Hmm, I made it, One BIG problem no spread whatso ever. Need incredimods
Oblivitus (author)  knex_mepalm5 years ago
So how well does it work?
Please tell me more about the bolt action mg. I dont full get it.
Oblivitus (author)  Millawi Legend5 years ago

The longer firing rod will travel a greater distance than the short one that fires the gun, therefore, as the long one speeds by, it will cock the shorter one multiple times. Look at the visual below. The images show the position of the long pin advancing. Each frame a round is fired.

example 124.jpg
That will only work if there is a very weak elastic band on the shorter pin, otherwise the larger pin may only cock the other one once(if at all) because as the elastic bands retract closer and closer to their original position the force that they will apply on the pins is decreased.
I would just use a rack and pin mechanism as it wastes a lot less energy in cocking the pin.
Good point, but the elastic could be spun around a wheel to keep it tense even after it resets and the problem would be solved. What is a rack and pin mechanism?
Using the wheel idea is just over complicating it.
Rack and pinion mechanism    and my SMG.

Oh, yeah, I knew about that, that's what I inteneded to be used when I did the drawing. But I don't see how that would eliminate the need for the wheel(s).

Ohhhhhhhhhhhh! Cool! im gonna go try it. Its gonna be damn hard though.
Oblivitus (author)  Millawi Legend5 years ago
Good luck, keep me updated.
Pretty well, works every time, pressure activated, shoots 10 ft or so at a good rate, its not like a grenade which flings pieces to hurt people, more like one to make them die in a knex war, so light fire behind them. One problem, not enought power to damage someone, but if I add anymore bands, it will stuff up
Oblivitus (author)  knex_mepalm5 years ago
Cool, make a video.
Well don't just sit there! Fix it! JKJK
I've done something, I didn't read the notes, so I made on which was pressure activated, so some pressure moves and and flings it,so, anything else needed to add?
Oblivitus (author)  knex_mepalm5 years ago
So you didn't make a trigger ring near the base? -_-

The bouncing Betty Grende seems very interesting and easier than the other one, I would like to try that one as well as soon as I am successful, i will post images
Oblivitus (author)  knex_mepalm5 years ago
Uhh, it would actually be extremely difficult to create, but it could be a devastating weapon.
KnexFreek5 years ago
i made this today and it works great!!!!!! it even has a safety that you can pull when you want to throw it
Oblivitus (author)  KnexFreek5 years ago
Really? Nice. Knex_Mepalm said that he made it too. Read his comments below for more information. Tell me more about it. I'd love to see a picture too.
uhm will you collab with me on it? it is a simple but effective design and it wont be to much work for you i promise
if you say yes i will give you way more info, and make a private slideshow for you too see and then help build it up a little more
I see you are working on it as well, good luck then, maite!(purposely spelt wrong) , so er... bye
Oblivitus (author)  KnexFreek5 years ago
No thanks, sorry. I'd still like to see pictures and/or have more information about it though.

maybe i can use this guide to make real life weapons and combine it with the disposable camera flash cap and shoot it!(without using knex)

Well, if you do, I definitely want to see them.
KnexFreek5 years ago
 im gonna try to make the machine gun revolver but i think it might break the ramrod if the angle is that steep
Oblivitus (author)  KnexFreek5 years ago
Okay, good luck, don't build it to be exactly like my drawing though, that's just to show how it might work. I'm not entirely sure how many barrels it should have or how the ammo will attach or be fed.
kk i wasnt gonna build it exactly like jous but knex mostly works in 45 degree angles
Please tell me more about the bolt action mg. Does the big firing pin go down slowly and make the small FP go back and forth?
chopstx5 years ago
One big problem with this: What if you throw it, but it lands facing you?
Oblivitus (author)  chopstx5 years ago

That's physically impossible. The grenade is thrown by you in another direction, the direction that it is thrown in determines the direction of the blast.

How? What if it decides to roll over to the other direction because of wieght, wind, ect.
Oblivitus (author)  chopstx5 years ago
The grenade would be weighted on the bottom, meaning that it will always land right side up, and since it has forward momentum will always roll away from the user in the direction that it was thrown.
Oh yeah...........sorry! =D
Oblivitus (author)  chopstx5 years ago

It's okay, this will be a good conversation for everyone else who doesn't understand it to look at.

Yeah. IT's a good idea too! I just don't know how you'll make one though...................
Oblivitus (author)  chopstx5 years ago

Knex_mepalm told me that he made it, read his comment on the grenades page.

chopstx5 years ago
Problem with last one: They will stick together. The end of the rod below the rod in the chamber will hook on the rod in the chamber, which might cause a jam.
Oblivitus (author)  chopstx5 years ago
It will not, I have already done it before and the reason that it does not stick is because the tip of the rod that is touching it is angled and the rod being fired will push it away because of this. Here is a visual.
example 123.jpg
Ah. I see.
KnexFreek5 years ago
OMG OMG i just gave this 5 stars and now its at 4.14!!!!!!
Oblivitus (author)  KnexFreek5 years ago
Sweet, thanks.

lol u have a couple things over 4 stars

Yeah, the Beast Pistol, Z35, and this.
and more !!!
Oblivitus (author)  KnexFreek5 years ago
-I added a new concept today, it's a more powerful mag fed shotgun design. Check it out.

-Also, I'm adding more concepts right now.

-I made a forum for people to post their own knex concepts. If you have any ideas, post them on the forum.
i cant wait to see the new concepts!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! i wants toos builds them!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
also i made a brand new knex repeating crossbow and its alot better than broydas

 I believe that the magazine on my chu-ko-nu is a non-interlock one.

Oblivitus (author)  bryoda5 years ago
What? I thought that it used a hopper.
 Nope,  I actually created it by accident, but it worked much smoother so i kept it
KnexFreek5 years ago
Yay! Can you add a link and my name when you get the chance? thanks!
Oblivitus (author)  KnexFreek5 years ago
Yeah, I will, I'm almost done building and modifying it by the way. Itlooks a lot different now.
Wow thankyou! I cant wait to see it! BY the way i am modding the mag tohold rod ammo. Oh and i sent you a patch!
Oblivitus (author)  KnexFreek5 years ago
I finished it five minutes ago, works very well, I will keepimproving it though.
Thankyou , do like how the trigger works? The space in the middle of thetrigger where the ram goes through is nice. Also how was building it? Doi need more pics? was it confusing?
Sorry for the barrage of questions lol
Oblivitus (author)  KnexFreek5 years ago
I didn't build from your instructions, I printed out about 10 of yourpictures of it to build from. I did not build your trigger, I mademy own. I modified it as I built it, so it looks a lot different.
does the rod go though the trigger like mine?
Oblivitus (author)  KnexFreek5 years ago
I attached the trigger the same way, the mech parts are different.
knex_mepalm5 years ago
I follow your revolver idea, just how will the bullets interlock insidethe revolver piece without any friction. Confused...
Oblivitus (author)  knex_mepalm5 years ago
The speed loader holds onto the bullets more loosely than the chambers of the revolver. That's all there is to it.
squarepants6 years ago
nice in theory but i really cant imagine it working in reality. I doubt that the barrel shown enough would generate a substantial amount of rotation on the bullet to make a difference in accuracy. In short, this is quite a far fetched idea-but I like it!
I have made one, but too reckless it only works 1/6 of the time, using aspun barrel and rubberband, and horribly hard to operate.
Oblivitus (author)  squarepants6 years ago
Yeah, I agree, I kept it because it's an interesting idea.
KnexFreek5 years ago



thanks :)

im gonna make a revolver with mags on each barrel
i did now lol

I was going to use something like this on my new battle rifle/sniper! I was hoping to use a new kind of sear system too, but perhaps not as it is very difficult, but in the long run they are much more reliable than block/normal true triggers!

i dont quite understand this, can u try to explain it a bit more, thx
Oblivitus (author)  noobererer6 years ago
Have you ever used a spring powered airsoft gun that you have to pull back a bolt/firing pin to cock?
yes i have...sorry for the really late comment...i was just looking back on this instuctable and saw this, for some reason it didnt message me this
Oblivitus (author)  noobererer6 years ago
That's okay, but anyway, it's the same idea as a pull that snaps back into place after cocking.
lol i understand...i that this was for like a semi automatic gun...so just to be clear, its just for the pull right?
Oblivitus (author)  noobererer6 years ago
so whats the point of a pull that springs back into place after its been, well, pulled :P
Oblivitus (author)  noobererer6 years ago
It goes back into the gun so that it doesn't stick out after the gun has been cocked, like I said, it's the same idea as a spring powered airsoft gun.
ok, but wouldnt the firering pin still be sticking out of the back of the gun does it have a casing?
Oblivitus (author)  noobererer6 years ago
I am going to make this simple, look at DJ Radio's AR-4 Commando v.3. His bolt is almost the same as my resetting pull.
sorry but im too lazy to look at his hole gun...i looked at the bolt and i didnt understand. what i take it is like a slide action pistol where the slide springs back
Oblivitus (author)  noobererer6 years ago
Watch his video if you haven't already.
ok i definatly understand now...i couldnt find the video awhile ago...again i was looking back on this becuz ill be building this weekend

Does it have a trigger activated by the ground?, or does it have some other similarity?
yes it has a trigger activated by the ground

Yeah, I figured, it's definitely a good idea.
KnexFreek5 years ago
i will make the revolver thing and mod it to my revolver
Oblivitus (author)  KnexFreek5 years ago
Cool, remember to post it.
kk i will ps after i post my latest gun i will start making ibles for them i was thinking tho, how would i transfer the ammo? with a trigger? with a push rod? by twisting ? use of rbs?
Oblivitus (author)  KnexFreek5 years ago
None of that is neccesary, read my description of the speed loader carefully.
i'm going to work on the slide action slingshot gun; i'm a genius at these things. still stumped on the tube mag idea, though...
Oblivitus (author)  mettaurlover5 years ago
Which magazine do you mean? What did I call it it? I don't have a "tube mag" idea.
the one with the shots parallel to the barrel-in real life, it's called a tube mag
Oblivitus (author)  mettaurlover5 years ago
The Dunkis made one shortly after I posted my idea, but he said that he thought of it on his own.
ah. i want to make one with the mag under the barrel, not over like he has it.
Look at this link for the dunkis' horizontal mag idea: http://knexinnovation.net/forums/viewtopic.php?f=2&t=782 and see if you can build on that.
Merugop5 years ago
I wanna make an innovation on this side ive currently got an slide shell eject weapon that ejects when shooted
KnexFreek5 years ago
i am going the post my slide action slingshot rifle/pistol with a mag soon also check out my nade
Oblivitus (author)  KnexFreek5 years ago
Have you successfully created the slide action slingshot?
yes i finished it yesterday the range is about 90 feet with surgical tubing
only problem is every peice of ammo has 3 broken peices to build it
Oblivitus (author)  KnexFreek5 years ago
Odd, I'm sure that there are other types of ammo that could be used even if it requires a few mods to the gun.
uhmmm it works a certain way so itll be hard to find a better source of ammo
Oblivitus (author)  KnexFreek5 years ago
Awesome, post it. Make sure to write under the credits; Gun thought up by Oblivitus, or something like that, I don't know of any better way of wording it.
i also finished yesterday a shotgun with a triple mag that loads three every time u shoot it is the design you explained in your ible about knex guns only i made it!!!! and it works great!! range is three shots going 40+ feet
Oblivitus (author)  KnexFreek5 years ago
That's great, I knew that one could work, post it without a doubt.

i think i am definitely going to try the funnel idea-i have a decent concept getting it to work may be hard though.
Lowney6 years ago
Aww, that guy's no threat! He can't even pull the trigger on his pistol without fingers!
Oblivitus (author)  Lowney6 years ago
Well, he could insert his other stick arm between the trigger guard and the trigger to fire it, lol.
Hehe bit inconvenient don't you think? How's he even holding the gun lol?
Oblivitus (author)  Lowney6 years ago
Ah that old SAS trick.
noobererer6 years ago
this is confusing
Oblivitus (author)  noobererer6 years ago
It's pretty simple, imagine a motor spinning a rod attached to the white connector. Now imagine the barrels on a machine gun chain being fired as it spins around.
o i get it...i just studied the pictures a bit more...but this definatly would damage the motor, but yea..elastics would work i think :P
how owuld one go about making a tube mag?
Oblivitus (author)  mettaurlover6 years ago
I don't know. I need more information.
i cant get the distance between the sections right; i've managed to get the tilted part but not the width of a rod...
Oblivitus (author)  mettaurlover6 years ago
What are you trying to do?
well, i'm trying to make a tube mag high-power rifle. a tube mag allows the gun to have a lower profile, as well as making it easier to aim due to less sticking out of the bottom/top of the gun.

This is an epic ible and should be collaborated.

Do you want to collaborate it with me? I will let you if you tell me how to do it.
I don't know how.

I figured it out and added you as a collaborator.
can I collaborate? I have some cool ideas that I may never be able to build.

My ideas cant be described with words, I need to make the pictures myself.

Then make a picture, and if it's good enough quality, I'll put it in the ible with proper credit, if not, I'll make another picture myself and put it in the ible (still giving you credit for the idea).

You know what, Im getting an extra shipment of knex from 2 instructables members, Im gonna make it for real.
Lol you're just stringing him along, right?

Yes, I will add you right now, but tell me if you add anything so that I can look at it for corrections and clarification. Please only edit your own ideas, I'll manage everything since it's my instructable.
Ok. First off, Im gonna make an idea called "repeating cannon gun". Basically, a multi shot cannon.
Oblivitus (author)  DJ Radio6 years ago
Okay, but inform when you add it to the instructable.

TigerNod6 years ago
Great idea, but I wonder if it would work.
Oblivitus (author)  TigerNod6 years ago
The biggest design problem would be the end of the barrel, I realized that in order for the round of ammo to clear it, it would need to get wider. Mepain also brought up a good point, he said that k'nex guns do not have enough velocity to support spinning ammo so it would probably just fly out of control.
yeah i agree... i think putting spin on it ive heard decresces speed (not velocity due to that being direction and speed and judging from what ive seem we havent mastered any velocity) there are other solutions, i remember some pistol i made the bullets flew strait (insted of flailing in the air) but when i rebuilt it, it did not work... somthing tells me its the quality of the peices you use not how long the barrel is (leat that also how it helps in airsoft)

ugh note to ppl and self dont type at night when you cant see the keyboard correctly and your half asleep...
Oblivitus (author)  Sypran6 years ago
Yeah, parts of your comment confused me, nice spelling too, but poor spelling is not uncommon online anyway.
true and many people do say I can't spell (hence why I get points off on english papers...)

Check out my new Z35 video on YouTube.
Really cool. Has a lot of extra's that are also seen on real rifles. I thought you stopped with building with knex?
Oblivitus (author)  TigerNod6 years ago
I have had this built for a while, and no, I haven't stopped yet.
Yeah! Oblivitus is still going strong! lol.
Oblivitus (author)  TigerNod6 years ago
I actually have at least three more k'nex gun instructables coming.
Is one of them a Z36?
Oblivitus (author)  The Jamalam6 years ago
Hey, try building my mag fed shotgun idea if you have time, I know that this one can work, it's pretty simple.
Oblivitus (author)  The Jamalam6 years ago
No, there will be no Z36. The CS3 will be released next, then the Ultra Pistol 2.
PLease don't end up like oompa but i'll definetly stop when i have build my crank operated turret using all my knex, still at V0.0001
Oblivitus (author)  knex_mepalm6 years ago
Don't worry, I will still be visiting this site, and I won't delete my instructables.
Hoorah!!!!! What will become when you finish making those three? will you quit forever knex, if you do can you throw a bucket of them offf a 20+ storey building?
Oblivitus (author)  knex_mepalm6 years ago
No, lol, I'm keeping my k'nex.
stop changing your pict...it looks like really stupied now
Oblivitus (author)  knex_mepalm6 years ago
Now it looks like the same guy but inverted colours or something, i have a horrible memory, some people can remember 4 gigabites or memory, but i have a limited storage of 1.5 gigabites, though i never forget anythign i remember.....
Oblivitus (author)  knex_mepalm6 years ago
I don't know what you are talking about, but I have a 298 gigabyte hard drive.
im turning memory capacity of your brain into a ratio as computer space. YOur pict, you dhould change it.
Oblivitus (author)  knex_mepalm6 years ago
Didn't you just tell me to "stop changing your pict"?
Cool! PS: You got a new subscriber.
Velocity = Speed.
velocity = speed+direction....
It must reduce speed, thus velocity. We learn it in britain that it is speed.
Ive Never heard that in my life since this is a science we are talking about is a standard.
In physics (wich I had to take), velocity is defined as the rate of change of position. It is a vector physical quantity; both speed and direction are required to define it. In the SI (metric) system, it is measured in meters per second: (m/s) or ms-1. The scalar absolute value (magnitude) of velocity is speed. For example, "5 meters per second" is a scalar and not a vector, whereas "5 meters per second east" is a vector. The average velocity v of an object moving through a displacement (Δx) during a time interval (Δt) is described by the formula:

The rate of change of velocity is acceleration, which refers to how an object's speed or direction changes over time.

you can convince me in any way shape of form that velocity = just speed, maybe you didnt learn it yet.
Too bad. It seems like you got a lot of comments in just a few hours. Maybe there will be someone that is really going to make all this!

Can I collaborate?
Oblivitus (author)  The Jamalam6 years ago
Yes, I will add you right now, but tell me if you add anything so that I can look at it for corrections and clarification. Please only edit your own ideas, I'll manage everything since it's my instructable.

that speed loader has been manufactured for revolvers in real life already.
Oblivitus (author)  An Villain6 years ago
Really? Cool, I didn't know that.
yes, i saw one in a cabela's catalog, here is an image.

Oblivitus (author)  An Villain6 years ago
It probably doesn't work the same way as my idea though, does it?
yes it does, you place the loader on the back of the revolver revolver, turn the handle, and pull it out. the bullets are then transferred from the speed loader to the revolver.
Oblivitus (author)  An Villain6 years ago
Yeah it's the same idea, but mine doesn't use a turning handle, so they're not exactly the same.
yeah, they are not exactly the same, pretty close though.
I am gonna try the auto loader revolver. However I fear that it would take very, very long to load, if it even succeeded. I have some ideas for the barrels. and then maybe put the mags on a br36 wheel so it could shoot like 160 bullets without reloading.
But i don't have enough tan clips... That sucks man.
The Jamalam6 years ago
With the motorised machine gun, this would damage the motor. I think that you should try and use it with a rubberband, like on the BR18 but a lot different.
Oblivitus (author)  The Jamalam6 years ago
Yeah, okay, I'll change the text.

I made a pretty wicked sear system. It uses a brokeded piece for it though, would you like to see it?
stale56 stale566 years ago
I also made a fully automatic rubberband gun mech, and doesn't launch them all at the same time, it is controlable. It was inspired by a different gun, but uses a different mech, I think... If you want pics of that, feel free to ask.
Oblivitus (author)  stale566 years ago
I'd like to see it, I'm interested in whatever ideas people want to show off.
Pic 1 is the RBG. Pic 2 is the paint version of the sear system. Pic 3 is the real version of it, with the system covered.

The sear system is cool! Mind if I mod?
Sure, here is a picture of the entire pump-action gun, it has a wicked awesome stock, and is a yard long.
Its the gun on the bottom, the gun at the top was an RBG that I destroyed.

I might post the mech alone on an Ible.
You can use the mech, just be sure to give me some credit =D
orngy 007.JPG
Of course I give you credit. Only useless noobs that can't create their own knex gun steal stuff from others. :-)
Oblivitus (author)  stale566 years ago
I looked at the pictures, they are both pretty interesting.
Thanks. I thought I had a picture of just the mechanism on the sear system, but I guess I never took the picture...
Oblivitus (author)  stale566 years ago
Yes, I would.
TigerNod6 years ago
Hey oblivitus I have a great and simple concept too. If I show it to you, could you list it here and give me gredit?
Oblivitus (author)  TigerNod6 years ago
Sure, you can post it in response to this comment, be sure to make a picture on paint in addition to a written explaination because I am a visual learner, a block of text may not be enough for me to understand it.
So? What do you think of it? Do you think this is the future of knex?
Oblivitus (author)  TigerNod6 years ago
What are you talking about? You didn't post any pictures.
I did! Is there something wrong with your internet? Here is another picture.
Three shots concept.bmp
Oblivitus (author)  TigerNod6 years ago
Okay, I can see the picture now. Can you please explain it?
I did that too! I think there is something wrong with my previous comment, I can see it below here but for some reason you can not see it. Anyway: Here it is: I call this a semi-auto repeater. This knex gun can shoot 3 rods (there can be more if you want) in a semi-auto fashion. After that, you can cock it and fire another 3 shots. I put some numbers on the key parts so I can describe it more easily. 1 is a barrel, this is the same as with an ordinary repeater. 2b is the bolt, 2a is also a bolt but it has been fired and needs to be recocked. 3 is where all the magic happens. If you pull it back and forth (it slides over part 4) it pulls back all three firing pins at a time. There is only one problem with this concept: the trigger mech.

Oblivitus (author)  TigerNod6 years ago
Thanks for the description, and I have thought up this design before, but the cocking power will be divided amongst the barrels, reducing velocity, if not also reducing range.
? I do not understand. Part 3 works exactly like a pump, so why does it get less range?
Oblivitus (author)  TigerNod6 years ago
I might post the idea later anyway.
If I were to make a guess on what it is, I would say it is a true bolt action, triple barrel gun... 2A and B being the rams, 3 being the slide/bolt, 4 being the thing the slide/bolt slides on, and 1 is the barrel... Just a guess, I'm probably wrong though...
Well, you were wrong but close. It is a semi semi auto repeater. You were right on 1, 2a and 2b, but part 3 can freely move over part 4 like a train carriage over rails. Part 3 works much like a pump and can pull back all the three pins at once. This means you can fire 3 times before having to recock. The benefits are that you can fire semi automatically and that there is no range penalty at all; all parts work exactly the same. There can be more barrels, and you can also change it to work like a shotgun or MG. I think this concept has the future.
Thats what I said, about #3... But the problem is that there will need to be multiple triggers. Either that, or make it so that if you pull the trigger X amount back, it will launch barrel 1. If you pull it a little bit farther, then you get 2, and then 3...
Yeah, I thought if that too. I think in a war three triggers would be better.
I think it would be kinda akward to have 3 triggers. Wouldn't you have to move your hand after each shot?
Yeah, maybe you're right, maybe your trigger idea is better.
So, what do you think? Isn't it good?

I thought you might like to know how I'm coming on the slide action slingshot. I have almost every thing built except the slide. But I have one problem, I found that the gun will have to be long, very long.
Oblivitus (author)  Killer~SafeCracker6 years ago
Yeah, I started one myself and I had problems with the slide too.
The Jamalam6 years ago
Mind if I mod and post?
Oblivitus (author)  The Jamalam6 years ago
Do I mind? No, go right ahead, I made this instructable to allow other people to build my ideas because I will not be building with k'nex anymore. Please update me on how the build is progressing and don't forget to give me credit for the original idea on the instructable, thanks.
No problem, Just I have a good idea for this, a new system.
Oblivitus (author)  The Jamalam6 years ago
How is it coming?
I took it apart, but I might try again another day.
Oblivitus (author)  The Jamalam6 years ago
I made an attempt at it, almost finished it too, but I couldn't figure out a way to attach the slide and the design has a friction problem during cocking. Would you like to see pictures of mine? I can post a video on YouTube as well.
Yes please! :D
Not bad... I'm focusing on my 2 projects at the moment, both coming along fine!
Oblivitus (author)  The Jamalam6 years ago
All right. So what is the idea?
Oblivitus (author)  The Jamalam6 years ago
I have added some more ideas recently, check them out. :)
stale566 years ago
It looks like it would work, the only thing that I think might clash is that when your pulling the rubberband/slide back, won't the rubberband pull the ammo back a bit? I know that slide won't interfere, but I think that the rubberband might hit the ammo, unless you have the ammo come up after the slide was pulled back. Here are some pics I made showing what I mean... 1. Current mech. 2. My version of the mech. The red thing above the mag. is the thing that makes the ammo load only when the slide is pulled back, that stops the rubberband from messing around with the ammo (thats the only way I could word that phrase). The red line closer to the front of the barrel moves the loading mech. back. The loading mech. snaps back in place by a rubberband. If you have any questions about the mech. please ask. I hope this was helpful.
Oblivitus (author)  stale566 years ago
Nice diagrams, but I'm afraid that they weren't neccessary. You see, in my design idea, the barrel would become thinner behind the magazine, so rounds could not be moved backwards, only forwards, and the rubber bands would slide over the top of the rounded edge of the gray connectors that it fires. The original idea would work just the way that it is.
