  • TheDunkis commented on Lucas The Boss's forum topic Knex guns

    Sorry, not sure what to recommend you since most rifle-ish lengthed builds require a good handful of pieces. You could try my BAW. Again, not a high quality build, but it was one of my larger ones back when I was fairly limited in pieces too.

    My apologies, I forgot that I didn't post the instructions for that one. If you only have 2 black y clips, you wouldn't be able to build it anyway. I'm not sure what other good builds there are with no y clips required.

    Depends what you mean. I used repeating when I meant semi-automatic (one trigger pull = one shot). A manually operated slingshot that has a magazine is also considered a repeater. I've seen designs that use a pump to push the bands back, but I don't know how to find them.If you mean a semi-auto, and if you want a real example, check out my page and look for one of my first instructions titled MP44. It's not a great build by today's standards, but it demonstrates one way to build a repeating slingshot. You could probably find a better example but I don't know any offhand.The way it works, one of the simplest ways to design one is with a rotating cog and a ratcheting sear assembly similar in concept to an escapement: https://upload.wikimedia.org/wikipedia/commons/2/2... .

Basically, you load a rubber band on each peg of the cog. The trigger controls how the cog rotates allowing a single band to be released per trigger pull. The simplest way this is done is by having two pegs as part of the trigger sear. One of the cog pegs catches on the first peg of the trigger. Pulling the trigger unblocks the cog peg from the first trigger peg, but then it catches on the second. Letting the trigger go unblocks the cog peg from the second trigger peg, and then the next cog peg is blocked by the first trigger peg, starting the process over. Another way to look at this is like an air lock. Only one "door" can be open at any given time to prevent all of the "air" from rushing out, and the trigger controls which "door" is open.

    Hey, apologies, but I never managed to make a functional version of this, so I never got instructions. This is just a "topic", which I'm not sure how they're displayed now or how you accessed, but back when I initially posted it, it was on the message board separate from submitting actual instructions.

  • Very Strong Knex Gun Ram Rod

    Very interesting, haven't seen a custom striker design like this before. Though a couple concerns. First off, if you're going to go through the effort of cutting up a metal rod, you might as work out a place to hold the bands instead of binding a K'nex piece (a modified one no less, but you could use a ball socket instead). Second, the range of a K'nex gun is typically dependent on the speed of the striker, which generally means you want as light of one as possible. There are other factors that using metal benefits, but weight certainly isn't one of them.That all said, it's certainly an interesting concept and I'd be very curious to see any further attempts you make. Like, do they make similar sized wooden dowels you could try using next?

    Indeed. We've all seen the value in it but it was just too large to tackle. It could literally be a book some day.Amen. Just having the willpower to build can be enough of a struggle. Did you get that idea independently too? I had the same exact idea, using a lever at the front of the semi-auto slingshot to act on the equivalent of a piston to automatically drive the trigger, making a truly fully automatic K'nex launcher. However, likewise, I could never figure out a frictionless trigger. Stacking up bands produces a lot of friction. Not to mention we'd realistically probably only get up to 10 or so bands before -something- starts failing.

And I'd love to see more pump actions, so do consider revisiting. It looks like it's off to a good start. It's not quite along my preferred style, but then that's just how modding goes, I encourage everyone take my designs and adapt them to their own tastes. Pin guides have always been challenging for me, they tend to be awkwardly placed on block-style bodies. It's something I'm actually trying to figure out on both of my current projects. So I'm glad you figured out something fairly clean with yours. Keep me posted with updates.We probably could go back and forth, so we should do it in an interview haha. I'll write up some questions and PM you eventually. I've a couple posts backlogged so I'm not in a hurry but I'd definitely like to start getting other builders involved so it's not just about me and my limited perspective. In the mean time, start thinking about answers to generic questions like how you started building with K'nex, your preferred kind of builds, etc.

    (not sure if the comments got out of order, 'ibles new comment system is slightly confusing)Ah, sweet, looking forward to seeing what you managed!

    Indeed, but it's a nice challenge in itself, so I'll get to it..someday. And thanks, it certainly was upsetting at the time, but it made me realize before putting it out there that it really wasn't prepared for the real world anyway. It could've crashed at any point and lost everyone's data had I not got backups working correctly, so it's better it happened before that. Haha yeah, we all remember our first block trigger (I've been redefining a lot of terminology to be a little more accurate/less confusing). Back when we thought our own versions were "simple but powerful" and all that. It was very nostalgic. I kept that design around for a long time, sad I couldn't even remember the video I got it from. As long as you never truly quit, that's a lot more than most builders. Haha...

As long as you never truly quit, that's a lot more than most builders. Haha, well to be fair, my Oodassault and Barackuda have been the only serious things I've really done in the past 5 years. It's taken me just as long to post things. Hmm, the MARR slipped past me, but looking at it now, it's pretty slick. I like the concept of it, modularity is oddly not all that common for launchers made of a construction toy. Have any other ideas floating around? Else could revisit the MARR and see what else you could do with it.Thanks, I really appreciate it! Your clip makes sense, it's all about the trade off between speed of reloading and stability. Man the magazines are finicky as heck. Some people have better luck than others. My hypothesis on your magazine is that the pressure of the pusher bands keep the magazine pushed out a little and allow the rounds to exit cleanly, but when it begins to empty, the pressure of the tilting bands overcome the mag pusher and the pole starts to barely stick into the round being fired, which causes a whole mess of problems. That's why I had to carefully rotate a white rod in the gap to distance the magazine just right. I think Killerk's magazine connection method that I followed with the 3.8 is a little more reliable in that regard, but then it sacrifices some capacity and is harder to make a locking mag pusher for. Look forward to anything you might do with it. I've been curious to see a rifle version of it, could never pull that off myself. Hopefully you can figure out your magazine. Oh yeah, I've been meaning to get more of these, at some point you wanna be interviewed for a meet a builder post on the blog? (yeesh, sorry for the wall)

    Heyo, thanks! Good to see you around.

    Many thanks!

    Thanks, let me know what you think of the 3.10 if you build it. Honestly, it was finickier for me than I would've liked, but still better than the last version that I posted. I haven't posted anything in a long time so I wanted to finally make instructions again. The blog has done wonders for boosting my activity since I'll talk about an old gun I made and then find ways I want to improve it so I can post instructions for it. Mmm try again, long story shot, the URL gets ruined when I put it on certain sites. I'll try to fix it.

    Thanks, though honestly I put the series on hold pretty quickly because I couldn't figure out what the next step should be. Like, you can go in many different directions after you learn the basics of power. Because of that, I wanted to make a very basic, very modular launcher that I could reuse for several lessons, like a basic block body, then a basic magazine, then a basic stock and pin guide, etc. But I haven't come up with it yet. Funny how it becomes more difficult to build something simple the more experienced you are. Yeah, I don't know why 'ibles decided to go back to its old style. Any sense of K'nex gunning community we had left died that day and I just about lost all hope.

But I had registered the domain name already so I figured at the least I could get a blog going until I see activity justifies making a full-blown website again. Glad to see you're still around. Hope you'll keep building and perhaps can help spark some activity back to a dying hobby. Just need to keep getting and teaching new builders I think.

  • K'nex Whisper Pistol [Semi-auto, Unique Mech, 6 Shots]

    Haha hey, man. Well truth be told I didn't contribute a lot and all of the guns I did make were relatively small things and unfinished concepts. Heck after asking you to help make a bolt action, I didn't come up with my own post-worthy one until just a couple years ago. Good to see you around, you planning on staying long? As you can see, activity has really died down. K'nex gun building just ain't what it used to be, so it's exciting when I see stuff like this posted.

  • Interesting take on the concept. I do think that shotguns are the future of war weapons since, well, K'nex just aren't accurate and all that great at range anyway, it'd make more sense to focus on spread to up hit probability (a concept that even the US military investigated in the 70s-80s I believe). To that effect, I think rate of fire and amount of pieces fired are more important than range. I imagine a pump weapon with large ammo capacity and easy reloading would serve better than a turret-based shotgun, but eh wouldn't be the first time Killerk and I differed on opinions.Anywho, at least keep your K'nex around.

  • Well, you need to get the energy from somewhere. In the form of a handheld gun, there isn't much space to build up potential energy aside from springs and rubber bands. K'nex themselves have little to offer in potential energy, but there is some. This is a really simple design, but it's about the best you can do without rubber bands. It'll get maybe a few feet.

And then I opened up a gap in the magazine so that it can be topped off while loaded in the gun.

  • I dislike that the TR8 and ZKAR are thought of as the pinnacle of pin weaponry because basically it stems from complacency. Like, the only prerequisite is that the gun fires a single projectile as far as it can and it repeats, and under those two criteria alone, yes, the ZKAR and TR8 are fine designs. But what about ammo capacity? What about the rate of fire? What about multiple projectiles increasing hit probability? The ergonomics? The piece efficiency? Suddenly there's so much more to work on, but basically we said "nah, too difficult, would become too complex." But I know that if you start with novelty for the sake of it and then work on optimizing it after the fact, eventually you get something that's practical as well.

But yeah, we could definitely use some things to drive innovation.

I'm thinking there just aren't enough people hearing about K'ex gunning and the ones that do find it too difficult to make anything worthwhile. I otherwise believe there's a lot more we can accomplish, some novel, some practical, but we just haven't been being creative enough yet. To that end, I've been thinking up a video guide series for introducing newbs to K'nex gunning by teaching them the basics quick and easy. I just haven't had the patience to actually start recording them. I'd like to make it a regular thing where I can pump out an episode a day or at least a week and I currently can't dedicate much time to that. After that, it's just a matter of throwing those videos out there and getting people interested.

I mean, it pretty much is ready, now I just gotta be patient enough to get all the the pictures some day. Last night I tinkered around and I ended up making a simple trigger safety mechanism. However, it only blocks the trigger, not the actual pin-catching part so there's still the chance the weapon can accidentally discharge if like dropped or snagged. Currently toying around with increasing the magazine capacity still with no such luck yet.

  • TheDunkis commented on sonic broom's forum topic KNEX guns in 2016?

    Sorry, didn't end up replying to this sooner. Appreciate the effort, but I was figuring something a little more in depth and broad. Like, I recall as a newb, I didn't know things like how to come up with a decent true trigger on my own, what kind of barrels existed or how I could build a gun body, what kind of magazines existed, etc. Like, basically what happened is I'd copy the parts off of one gun and then end up reusing those over and over such that I had a sort of build style developed even when I was more familiar with K'nex. So what I want to do is basically make a guide specifically for each concept, like one day I'd have a video on just the different kinds of barrels you can make for both rods and connectors and how those can then fit into a K'nex body.

It'd be nice to have a flux of new instructions.I keep thinking to myself I want to start a guide series (video or otherwise) on getting started in K'nex gun building so we could hopefully attract some new builders.

Changed front of gun to be more compact, have simple ramp, to be flat on the bottom (in case I add more to the front of the magazine), and to be easily muzzle loaded.

Changed front of gun to be more compact, have simple ramp, to be flat on the bottom (in case I add more to the front of the magazine), and to be easily muzzle loaded. While I don't like the looks of this one as much, I figure the practicality overrides the aesthetics in this case.5. Finally, I removed the gears from the magazine, used another piece which lets the ammo flow freely. It's not really a rotary magazine anymore, more a small drum magazine. Anyway, filling the magazine should be much easier now, just drop ammo in, no need to push.

  • Yeah, I suppose it's not readily obvious. K'nex guns can have all sorts of weird and goofy triggers because there really aren't any pieces that really emulate a real trigger well. Also, just FYI, I don't mind at all because I'm still active and enjoy helping people with my things, but in general you should probably pay attention to when things were posted and when the last comment was (like 4 years ago in this topic's case). Otherwise you'll tend to revive dead topics and likely no one else is going to respond to you since they've long since moved on, sadly. But otherwise it's cool to see someone else getting into K'nex weapons. Good luck and enjoy!

  • Dunno why I keep posting here but I'm happy to say the Barackuda is coming along nicely. Changed the stock, trigger, front + ramp, and magazine since the version in the picture, so I'm gonna finish it up, get a new picture, and then maybe get another video. Then I want to be done with it... I've been meaning to post it but haven't quite been satisfied enough with it at any point.

  • K'nex Magpul PDR instructions

    Noice. Yours is probably my favorite. I ended up getting an airsoft version of the PDR-C because I liked it so much, so someday I might use yours as a basis for my own.

  • Thank ye. Yeah, I'm surprised the idea existed but was never really used in a gun until now. I'm pleased with it. Trying to make it more war worthy though.

  • Alright, don't have a picture, but I mostly finished up the redesign last night. Will make small tweak or two to the stock and then probably tweak the magazine, then I'll be ready to show it off as the third version. Maybe one of these days I'll even post... But golly the activity is nonexistent.

  • Got a picture of the attempted redesign. Also showing the new front. Again, I liked where the stock was going but the bolt handle doesn't work out quite as nicely, so I think I'll go back to using my old bolt handle but I'll be reworking the trigger for better range and I'll try to make the stock design a little cleaner, somehow.

  • Been working on this off and on over the week. I came up with a new stock and bolt design, and while I like the new stock, I don't like the new bolt. It's not as smooth of a pull and I'd have to mount the bands above the bolt handle. I'll get a picture because I think it looks neat but I'll probably end up changing things again.

  • Better range and accuracy really. You could test for yourself if you have a TR available. Load yellow rods or whatever ammo you like best (other than finned ammo which obviously would be superior anyway) and some Oodammo, then do some fairly long distance shooting. Rods tend to spin out quite wildly, often flying way off the mark at far enough distances. Oodammo usually continues a fairly straight trajectory, even if it begins to tumble.And actually, no, I developed the latest Oodassault pistols to have a really quick reload process, basically an en bloc clip, faster than even most removable mag setups and definitely faster than manually reloading a turret one by one. In theory, you could scale this up into a stocked weapon, perhaps with a railpin for more range. I just like the compact...

  • It's basically the best ammo (more in the sense that it's the least bad) to fire other than finned ammo. And I dunno, at first it started as a novelty for me, just be the first person to come up with a practical, magazine-fed repeater for Oodammo. Then it turned more into a challenge to make a practical war weapon. I'm still decided that if I go to a war, I'm going to use my Oodassault.

  • My main competitor was the Mezak. Eh, the names of others escape me. I think Killersafecracker (something to that effect) made a couple promising designs that I also competed with. Those would be a start.

  • It is a bit disappointing, activity is down and it's more difficult to come up with an original idea. But just keep at it. Something you could try is building other people's Oodammo pistols and figure out what it is you like about each one and what could be improved. Then use what you learned to make your own.

  • Ha, man so much time flies between when I actually do stuff. Trying to get back around to fixing up the Barackuda. I'm tweaking the front still with the goal of perhaps improving the magazine design, perhaps not. Otherwise definitely want to improve the trigger for more range, think I figured out something to keep the same design, just block further back and hopefully not compromise the strength of the back section too much. Also, I in all my madness have been looking into a large, twin drum magazine design. I've the general design down but not the pieces to make it, so I'll order them at some point. I've no idea if it's feasible at all but if it did work, it'd be able to hold 40-50 rounds rounds or so.

  • Sure, man, that's fine.

    Yeah, I got one here. I wasn't able to come up with a better one at the time, though I'm sure it's possible. At the time this was created for a gun intended to fire so I couldn't compromise with the magazine design, but you could make something a little nicer if you change the internals of the magazine to suit a mag release of your choice.

  • Well, I can't accurately say because the idea for the barrel came a bit before and then I figured out I could give it a slide but didn't really have a gun in mind to use it for. Then one day I happened upon another user's slide action Oodammo pistol and I was less than impressed, figured I could do better remembering the slide and barrel I came up with. I got right to building it and from what I can remember I built it pretty fast, I think on the same day or the next day after seeing the user's post.

  • The very first version of my Oodassault 3 was actually slide action, but I decided that the slide wasn't all that necessary. Just keep at it. Honestly, you missed the Oodammo pistol craze by a good while but it's always interesting to see people's different designs. Something I was trying to sort out was a way to separate the rounds in the magazine to reduce friction, perhaps you could figure out something?

  • Bleh, so I went back and forth with the bolt action idea and the gist of it is the body construction where the magazine mounted + bolt pin wouldn't be as smooth as I thought. Also, just didn't think I'd be able meet all of my goals, so I instead turned focus back on to making the Barackuda better. Currently I changed the front of the gun to be a little more compact and have a simpler, solid ramp so that muzzle loading is easier. I'm planning some other changes, then I'll get pictures.

  • So I gave up on my last idea and said I may revist the design but in the form of a compact bolt action. Decided to start on it tonight. It'll utilize a rotary magazine similar to the Barackuda but I'm aiming to eliminate all of the shortcomings of the Barackuda. It won't be the prettiest of my weapons, the first one made completely for the sake of performance + some quality of life features. Maybe this will be one of the few ideas I see through to completion...
