FYI this is for making shells

yingyangcuzins (author)2010-12-13

hay I have built a lot of knex guns in my time I fount out if you cut a bic pen it works better than tapping some spacers together make sure it is a cheap bic pen not a clickie 1 one withe a cap

This gun looks amazing, and I hope that you do post it, since I would love to make it. p.s. I fixed up the grammar in the intro, yes I was that bored. here is my new sniper it has a shell ejecting mechanism but you have to pull the protector thing back so the shell can fall out of the gun. I used killerks ball socket mechanism so the range is about 70 to 80 feet. I used ironmans rail system, I like the design, I like the range, I like it , I'm not going to post it but if you want to make it just take a good look at the pictures and you should be able to build it.

run-on-sentence, big time

knexguy (author)grevious2009-08-30

You missed the first capital. 'Killerks' should have an apostrophe. I could go on. If your going to do something, do it properly.

grevious (author)knexguy2009-08-31

i just used the instructables spell checker, blame that lol.

knexguy (author)grevious2009-08-31

Then you should have said you fixed the spelling, not the grammar.

grevious (author)knexguy2009-09-01

i see im in the wrong here, and i accept that i am, thanks for pointing this out :P

Dit is te ingewikkeld, ik heb wel een systeem dat HEEL erg simpel is, en toch hulzen vrijlaat.
Misschien laat ik nog wel is wat foto's zien ofzo =]

The "protector thingy" is called a chamber slide.

Looks good but I highly doubt you got 80 feet, but I will still five and fave. Good job.

Its a good sign- a good sign that people dont hate a gun because of false claims.

The Jamalam (author)DJ Radio2009-08-27

See this is what I hate about zak.

dutchwarlord (author)The Jamalam2009-08-27

i love zak he really make good innovate guns

DJ Radio (author)dutchwarlord2009-08-27

I guess you could get 80 feet with this if you put 5 bands on, it uses shells, so there is no mag friction.

coreyt (author)DJ Radio2009-08-27

Wrong there is mag friction the only way to make a frictionless shell system is by having the mech hold the shell part with this system the blue rod rests on the cut grey and ball socket and has the force from the mag band pushing against the shell which pushes the bullet up so it is pushing against the cut grey and ball socket understand (probably not).

TheDunkis (author)coreyt2009-08-28

You're both half wrong. The way this system is set up there will be a little bullet friction but not nearly as much as the friction without shells. The grooves hook on to eachother which causes the most loss in range.

coreyt (author)TheDunkis2009-08-31

i never said how much i just said there was some

DJ Radio (author)TheDunkis2009-08-28

With shells, the rounds dont touch each other, right? Mag friction is basically other rounds touching the loaded round.

TheDunkis (author)DJ Radio2009-08-28

Exactly. At the same time the pressure of the magazine pushes the round against the top of the receiver also causing friction.

DJ Radio (author)TheDunkis2009-08-28

On my Jackal v3, it proved to be not enough. There was so little friction in the gun that the round slid down the shells and caused reliability issues. That is why it failed.

TheDunkis (author)DJ Radio2009-08-28

You get better at problem solving the longer you K'nex. My last shell gun shot perfectly. Nice range as it didn't require as much movement as a turret or a bolt. However, I had a problem with my shells ejecting. I'll take another swing at it later. Ultimately, turrets are better for reliability but a little more piece costly than just using a magazine with shells.

DJ Radio (author)TheDunkis2009-08-28

My shells ejected fine when I made it. Knex mad built my jackal and said it shot fine, but the shells didnt eject. Exact opposite of what I did. But then again he probably didnt make it right because he only had 1 picture to work with.

The Jamalam (author)dutchwarlord2009-08-27

Yeah he does make good stuff. Just his personality is a bit... bleh.

Der Bradly (author)The Jamalam2009-08-27

You just hate him cause of that argument you lost against him.

The Jamalam (author)Der Bradly2009-08-28

No, I'm not like that. Seriously it's very... femenine to hold grudges (mepain, razzlekunai, you know). I'm past it now.

razzlekunai (author)The Jamalam2009-08-28

I hold grudges. Hahaha. Proof?

The Jamalam (author)razzlekunai2009-08-29

The fact that you still hate me after the months since the Zak incident.

razzlekunai (author)The Jamalam2009-08-29

HAAATE? HAAAAATE!? I don't really hate you. It's just really fun to pick on you because of the Zak incident. Not because of grudge, but because it's fuun. c;

The Jamalam (author)razzlekunai2009-08-29

Lol... surely it's more fun to pick on Dj :P

razzlekunai (author)The Jamalam2009-08-29


The Jamalam (author)razzlekunai2009-08-30

Lol yay!


Lol... not really, if you think about it, you can see it.

DJ Radio (author)Der Bradly2009-08-27

Here is what I would do. I would just dismiss the arguments, if it persists, I would use the same argument that he is using against me. I would say he is lying about me lying about my ranges.. Blah blah blah.

I agree.

did you see mepains and zak's new oodammo pistol i just built it today it's really easy to load compared to the other ones, also i love his bolt-action asssault rifle i have that built to. zak makes some cool guns, so i agree with you i love zak

Mezak pistol? Ima check it out.

finished building the gun today

That he doesn't like people who lie?

Sorta. It's complicated. But that he decides to bring all of KI on you because he doesn't think a statement is plausable as well. I don't get it. If one is on you, they all come with because they have no fun on that site lol...

I dont think it is unreasonable to be a bit cheesed off about somone downright lying about ranges and whatnot.
