TheDunkis' Oodassault Pistol Version 3.6




Introduction: TheDunkis' Oodassault Pistol Version 3.6

About: Just an aging K'nex launcher builder

Yep it's finally here. Really all I needed to do was add different steps for the new magazine to the other instructable but I figured I'd give you better instructions this time. This should be easier to build with clearer pictures and a better process of putting the gun together. I decided to make the gun in layers instead of of sections. Anyways onto the specs of this gun.

5 layered, compact design
Very simple two part trigger
Sliding Magazine Tilter
Simple safety mechanism
12 Round magazine

Range is...I don't know. I never measured but in theory it should be a just a bit more than the average oodammo pistol as the trigger draws back further and the magazine is a little farther forward.
Accuracy is near perfect horizontally. Mine has an interesting hop to it though. I'm not sure if it will be the same with yours or with different oodammo pistols but it's nice in my opinion as I don't have to compensate for gravity. Humans are rather tall targets anyways. =p
It's as durable as it needs to be. I wouldn't throw it at a concrete wall but it manages to survive a fall from 5 feet.

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Right Outer and Inner Layer

Like I said, We'll be building the gun by layers. There aren't that many directions to follow for that reason. It should be relatively easy to follow but feel free to ask questions if you're stuck.

1. These are how all the black hands connect to the white rods in the next picture.
2. This is the very outer right layer. Pretty simple right?
3. This is a layer in. Still pretty simple. The black hands connect to the white rods normally now.
4. Put the last layer on top of the other layer. Just line up the holes and put the white rods though them. This is what makes the gun relatively durable for a compact gun.

Yeah...not too hard. Moving on.

Step 2: Middle Layer

This is where all the magic happens. 'nuff said.

1. Top of the barrel. Easy, easy, easy. I don't even know why I keep adding these little comments to each line...
2. This is probably the most complicated part of the instructable. The modified orange piece isn't needed. I figured it would be a piece most people would have from pieces breaking. Use a dark grey if you really don't have one. It's not a big deal.
3. The trigger. I told you it was simple. It doesn't matter if you use the blue cap or not. I'm not sure what the difference would feel like.
4. Add all of the parts like shown.

Step 3: Inner and Outer Left Layers

It's exactly the same as the right layers of course.

1. Grab these.
2. Grab all these and put together whatever shown.
3. Put that at the back of the gun here. Put all the black hands while you're at it.
4. Connect all the parts like shown.
5. Make these.
6. Add the parts as shown. The black hands should just click onto the ends of the white rods stick out.

Step 4: Extra Bits for Comfort

These aren't required. I just like having them.

1. Grab all these.
2. Add the light greys (or oranges in my case) on each side like so.
3. Slide the tan into the hole here. It's not as hard as it may seem.
4. Slide the dark greys (or purples in my case) in like so.

Step 5: Magazine

It's pretty basic. Nothing much else to say.

1. They're exactly the same. Build them both.
2. Gather all of these.
3. Put the magazine together. Should be easy enough to figure out.
4. Grab another white rod and put it in the hole. Then connect the black hands to it.

Step 6: Make It Work

Adding the rubber bands and such. Just follow the images like usual.

1. Everything you'll need. I don't know what kind of rubber bands you have so just use whatever works. The firing pin has two #64s wrapped around and in front of the orange. I'm not sure how strong you can make the gun but I think the gun will give before the pin will.
2. Trigger bands goes around like this.
3. Two rubber bands will work best to keep the pin balanced.
4. Use as many bands as you need depending on what rubber band you'll use for the magazine pusher. You'll want to make sure it's strong enough to resist the force of a full magazine but weak enough that you can actually tilt the magazine.
5. However you wrap whatever rubber band you have, make sure that it pulls towards the front so that the pusher will lock when pulled down.

And now the gun is functional just not set up.

Step 7: Loading and Firing

Ooo our favorite part of K'nex weapons!

1. This isn't required to load the gun. I just figured I'd show you now. This is the safety. Just cock the gun and twist the trigger guard so the blue cap fits in between the gap in the trigger.
2. Oodammo. Now. Get it. 12 exactly. Or whatever you want. I just used 5 for this example.
3. Pull the pusher down until it's locked own like so. Depending on your bands it should be relatively solid but I would be careful about making any quick movements while loading.
4. Pull the sliding tilter back. Be careful not to do it too hard or you'll snap it off. Easy fix though. Add as many pieces of oodammo as you want up to 12. This gun can also use clips I just didn't bother showing how.
5. Let go of the slide, pop the mag pusher, and turn off the safety. Now you're ready to go. For best results, point away from your face. I wouldn't shoot anyone else outside of war. Go ahead though if you want as long as you know I'm not responsible and yada yada... sue the parents for not supervising the child if he manages to hurt someone, not me.

    4 stars great gun i used 3 fat rubber bands its dead accurate for about 50 feet i nailed a small book from opposite sides of the yard, but i made it single shot becuz the auto loading worked once out of about 20 tries, but I'd build it I also modded the barrel to load any single rod or connector, even micros

    could you like pm me or something the part count cause i want to know what im attempting before i attempt it

    Sorry, don't have one. Maybe someone else does. If you end up building the oodassault and you're capable of doing so, I recommend trying to make the 3.8 in one of my threads. Unless you really like the hand tilter, find the other thread for my 3.7 but otherwise the 3.8 was more efficient for reloading.

    where is the tread for the 3.8


    Reply 8 years ago on Introduction

    Click my name, go through my threads. It should stick out when you see it.


    9 years ago on Step 7

    Do you have any instructable on how to make a loading clip for this gun? That would be awesome cause I'm going to war :L


    Reply 9 years ago on Step 7

    I don't know how well they'll work with this gun but check out the thread for my 3.8 and check those out. They should be pretty easy to build.

    Good to see you're still active Dunk <3

    alright so i had some free time last night so i built this gun just for the hell of it.
    i have got to hand it to you i love the design and construction techniques and the instructions are simple and easy to follow
    so good work with all that
    the trigger mech is great the ram could use some sort of catch but i isn't a huge deal
    i want to point out that i followed your design piece by piece to get a feel of what you thought worked best
    however i am however finding the gun to be quite touchy
    the little tilt mech is always breaking and i find the whole tile mech to be a bit touchy considering the rubberbands holding the mag in place need to be stronger than the band pushing the oodammo and then once it is all banded up the whole thing is too tough for the little tilt trigger to work without breaking not to mention you need alot of tension holding the mech up for it to work or else the whole thing will blow up
    the gun seems too unrealiable due to the tilt mag if the mag could lock into place then it would be better
    anyway like i said i love the design and construction however personally i like the handle without the very middle layer sticking out it makes it more comfortable
    but genius construction and the mech is so close to good im just finding it to be touchy
    id recommend building it because it is a great design easy to build doesn't take many parts its a quick build and works alright once you work out all the kinks not perfect but i seriously like the work keep it man and that is my review of it so far if you could give me any pointers that would be great and if ive stated anything false let me know man keep it up!

    Alright thanks man. I guess it's still one of those un-userfriendly guns. If set up right, you shouldn't have any problems with that but I can't build the gun for everyone so I can't make sure they're doing it exactly how I did it. For example, you need an incredibly weak mag pusher, just strong enough to make sure the rounds load so that you can use a medium band for the tilter. I managed to do this with the bands I had but I'm not sure if everyone else could. I suppose if someone really wanted to, they could take off the tilter and make it more like my 3.3 version with the locking magazine.

    Yeah, I wish I could improve it but it's about as good as it can get in such a small package. I could possibly make a new version using my new charging handle concept. It would have a pin lock in a sense and a pin guide to boot. I don't know how strong it could get though before something breaks.

    alright so i gave it another shot and this time everything seemed to work flawlessly!
    the gun is just really picky on what bands it uses however once you figure out the delicate balance it seems to work great
    i really like the gun for what it is
    i just made a review that ill be posting up on youtube so good stuff man i learned a lot building the gun and look forward to more projects from you
    anway ill cut down on the chat clutter
    good gun "rubberband picky" but other than that great build

    OK awesome. Much appreciated. I look forward to seeing it.
