The S3 Semi Automatic Gun (SA 3252)




Introduction: The S3 Semi Automatic Gun (SA 3252)

About: I used to build K'nex guns. I'd like to think I've grown to be quite good at it, however, I've lost most of my interest in K'nex over my first couple of years in High School, but I do occasionally still come...

hey guys ! i know a lot of you were waiting for this, and it's finally here ! yes, you read correctly. i'm finally posting my S3. for those of you who are not yet familiar with this magnificent concept, i advise paying a visit to oblivitus' profile, where you will find many 'ibles concerning different versions and mechanics of the concept, the SA 3252. after that, you should also go check out my other 'ible presenting this gun from when i started working on this version. i just want to say that this isn't the final version, and i do believe oblivitus is going to keep on working from where i am now, and i think he's going to try to make it shoot yellow rods from a TR18. i might continue it too sometime, but for now i have a very interesting new idea for a semi auto that i am burning with eagerness to try out. so some up to date stats, shall we?
ranges- 45 feet on the first shot and about 10 feet on the last shot
quite accurate
5 shots
shoots 1-slot connectors
smallest version yet- mostly 5 layers, some areas 7 layers, but all with blue rods
strongest version yet, pretty powerful
very comfortable
i could keep on, but i think that's all you need to know ; )

needless to say that credit goes to oblivitus for most of the concepts in here, and also quite a few of the parts and design.

so without any further delay, allow me to present to you the S3.

also, don't forget to RATE, COMMENT AND SUBSCRIBE !!! for more awesomeness.

Step 1: BALLS !

i'm just gonna leave this step empty because of the horrific new display that requires you to see all the pictures at once, making it very annoying to go down to the comments. also, a quick reminder to read EVERY image note. sometimes you think they're long, boring or unhelpful, or you can manage, but trust me, on a complicated gun like this that except for myself and oblivitus, pretty much nobody fully understands everything going on here (until you build it), you need to pay attention and make sure you're not wasting your time doing it wrong.

Step 2: All the Mehchanisms in One Tight Box

this is probably the hardest step, especially since you have to deal with making all the paper fillings, taping precisely and banding very precisely. just get it over with, and do try to invest some time in making each "special" part so that it comes out good. about the paper fillings, i think i used some relatively thin paper of 3/4'x5'. you gotta find the size that best suits your type of paper and make precise cuts and rolling. just take a little more time making these, and you will be glad you did. so get going...

Step 3: Stock, Handle, Trigger, Slide

this is what i have on mine, but it's very mod-friendly. read everything in the image notes. i explain some more there...

Step 4: Magazine

make the mag. simple step

    wow man nice work! it's looking extremely good... i'll add it tomorrow, i'm going to bed now, just answering a few comments before... it really really looks awesome. i think the magazine would work better for you (and i know the bullets shoot further too) if you put it in the other way, as in, the red rod in the front. i especially liked the hole in the middle. it has a kind of retro-modern design to it. i think the side handle is a bit too close to the spool and you might get hurt, and also, you should take off the "key" thing from the spool when you're firing, if you don't already. it makes it stronger. also the supports in the back to make the stock level with the magazine are cool. where's the rubber band though?

    yeah i no and i havent got big enogh bands but i shot it with other ones tho im going to get some soon and i never ment to put the mag in that way aswell lol

    oh ok lol. i don't have long bands either, so i just used a few bands tied together.

    Great, I'm glad that people there are now going to be people out there who will understand this design (as a result of building it). Make sure to put one of your videos at the end or just something that will show people how to operate it though. Like I said, I want to build it but don't have the parts right now.

    yup, i'm super excited about this. i mean, it's the first ever posted version of the 3252... that's big ! i can't wait to hear one "built it, awesome gun. here's a picture:". you know what i mean? and yes, people can finally fully understand for the very first time exactly what is going on in that big blob of plastic... you know today someone sent me a PM saying he thinks i'm the best user on the site. you know how good that feels? the thing is i kinda feel bad taking all this credit for a gun that is your vision and has been your goal from the start... i hope you post something too man, people are forgetting you invented this. i hope you get that Z3 wrapped up and start working on this. anyway, i am postponing my semi auto concept because i start school in 3 days, and it will surely take me more than that. anyway, i'd rather focus on an awesome idea i have for something. it's a long explanation, i did it twice (maybe three times, i don't remember lol), and got it really long, messed up and bad. i'd rather just finish it up, i'll just say it's a repeater, because i can definitely do that quickly, and upload a slideshow and a vid and then i'll explain it better. in a word, it's a bullpup bolt action with a removable magazine, but it's completely new, trust me, no one has ever done it before, i'm positive. good luck with the Z3 man.

    Yeah, it's cool to get recognition, definitely. Enjoy it now, although you won't care as much about that as you get older. I'm just as happy to see other people succeed and to help them as I am for myself. And I don't mind if few people remember that the idea came from me, I'm happy to share the spotlight with someone who deserves it and just to see my idea being realized. And your new gun sounds enticing.

    once again, i don't think the joy of recognition changes with age. it's just something that might fade once you have it already. it also depends on the type of person you are. anyway, i'm glad you don't mind, and that's very nice of you. i however do think you deserve the credit, and most people don't know that we worked together for so long, and before that you worked alone for even longer. i guess most people just think you came up with the concept, like TD came up with the AC concept, but never did anything with it. i'm just saying people should recognize you as the mastermind behind this gun. nevermind, no pressure if you don't get it done yet. about my new gun, it is going harder than i expected, and there are some problems i did not anticipate, but i think i can figure everything out. my original goal was to shorten the typical bullpup weapon, but i guess that's not really gonna happen. i am however still going to make a pretty damn awesome gun, even if it is conventionally sized. the handle will still be closer to the stock, and the loading will be much more comfortable as well as much quicker. i expect it could get like 2 rounds per second... once again, you'll see why when you see the gun. even if i don't manage to fix everything, i will still upload it as a failed project, and i will try it again sometime from scratch. i have already learned a lot that might help me if i go back to the drawing board. anyway, i hope i manage to get a working gun, and i will still probably redo it.

    You know. I thought of myself as pretty mature lately, but I'm realizing now that my desire to see others succeed, yourself included, isn't completely unselfish. I think part of what makes me want to see people succeed is to live their success through them. I'm going to have to work on that. Just thought I'd tell you that because I do feel guilty about that now. There's a person I know who I realized was doing the same thing that made me realize that today. I may be helpful but I'm definitely not perfect and I don't want you to ever think that I am. Honestly I've been being selfish.

    relax, it's ok. nobody's perfect and we all have that jealousy or need to be known deep down, just for some it's more unconscious. i knew there was something of the sort involved, but it's better to let the person figure it out himself, or just keep thinking what he said, rather than pointing it out to them, because that makes me seem jealous or something. anyway, i'm glad you realized that.

    Mmm, yes. It does depend on being used to it, right, but that factor corresponds with the passing of time. Building one maturity level on top of the next will change what gets you excited. Yes, probably some information lost in the general public about how the idea started and progressed, but that's all right. Einstein said something like "You can either work to be recognized as great or work to actually be great". The gun sounds great. I'd like to see 2 shots per second without a doubt. How many rounds do you think you can fire consecutively that way in the short term and long term and what do you think the potential for the range is?

    alright, age changes the level of our reaction, but a person who has never gotten recognition will be excited the first (few) time(s) he gets it. great, i'm glad you think that way. as you remember my REMPAR was 3 shots per second. this idea would have a similar rate of fire, because it's a similar idea as far as what matters for ROF. it can fire as many bullets as there would be in the magazine, and the magazine has no limitations, so virtually infinity. the ranges would be very high and it would be very accurate, since it's bolt action. i expect a minimum 70 feet, but it'll probably be more like 100 feet. so yeah, like i said probably the best repeater so far, because it combines both worlds- efficiency (bolt action, and just an efficient layout) and speed (very fast reload system. i'll keep it a surprise for now), as well as a few other key characters, like accuracy, comfort, compactness, looks (imo) etc. it is basically a much better version of the REMPAR in a much smaller body, combined with the bolt action mech we all love so much, and a much more comfortable gun. it's like my S2 in theory- a much much denser, smaller gun for a mechanism i did before, in an attempt to make it a lot better for battle, as well as being a combination of a few mechanisms. btw, what do you mean short and long term? if you mean range, then i guess it depends on how long it takes you to aim and fire, bring the gun down to load and back up again, but i get the feeling that's not what you meant.

    Well that sounds great, a giant mag capacity would make that perfect for battle. What I meant by short and long term range is what you expect the range to be when you get it firing, and then the longest range that you think is possible for the design in the future.
