>>64549287Cool thread>What’s the *most clever* improvised design you’ve ever seen?3D printed Glock and AR receivers>Have you ever built one?Glownigger question
>>64549287>What’s the simplest firearm mechanism you've seen?Electrically ignited pipe musket. Simplest repeater, that but with superimposed chambers. (Well okay, maybe not simpler than just duct taping two pipes together, but superior in many ways)
Just thought of a fun albeit dangerous project. May update if I decide to go through with it.
>>64549287This is one I was always impressed by, it's one thing to make a gun with some plans or something to copy, it's entirely different to to make something that actually works completely out of left field.>This .380 automatic pistol was brandished on construction workers by a man living in a shipping container on site who had on several occasions entered the firm saying he could not stand the noise and dust that the trucks were making. After being arrested he told police that he had originally built the gun to defend himself.The 3d printing stuff is particularly clever, uberclay's ryno is brilliantly executed and I'm big fan of pilotgeek's maverick.
i don't ever recall seeing if someone ever made one of these & tested if it worked, but its really cool nonetheless
>>64549287>What’s the simplest firearm mechanism you've seen?Browning's falling-block rimfire. One moving part.
Hypothetically, would a PVC pipe be a reliable receiver for a STEN style weapon?
>>64550632it wouldn't be reliable, but it would workthe fire control is probably gonna slip a lot, so you'd end up with a runaway guni'm sure with enough JB Weld you could get it working flawless though
>>64550648How would you recommend modifying the standard STEN fire control to mitigate this? Do you think the issue would be in the pipe warping during use?
>>64550663you'd have to very heavily support the fire control to the receiveryour main worry will be the sear skipping or deflecting in any way, so you'll basically have to create a sort of "frame" to keep it stabletake any long PVC pipe, and you'll see how flexible it is, now think of how much flex there would be if you were to remove any material from it
>>64550723Its probably a stupid question, but could this be somewhat mitigated by wrapping it in tape or plastering it in epoxy? Im Hellbent on building a reliable gun from PVC or worse. Youd cringe to know what else Im going to try to use. Worth noting its not exactly a STEN, just similar.
Any resources/tips/guides for improvising ammunition? Ive got knowledge on everything but anvils and the casings themselves
>>64550782anywhere material is removed, material must be added, and any length to flex must be supportedtape isn't going to do anything, and while epoxy is better, its going to have to be a very strong epoxyyou're basically just gonna have to slather it in JB Weld & fiberglass wraps, then take a dremel to it, milling out the slots required
>>64549287Goated thread, thanks man
>>64550785I saw something with using matchsticks to improvise ammunition. It was in the Ark torrent.magnet:?xt=urn:btih:6d72a0d13d050f6ed00179ffd4294b549714140a&dn=The%20Ark&tr=udp%3a%2f%2ftracker.loadbt.com%3a6969%2fannounce&tr=http%3a%2f%2fopen.acgnxtracker.com%3a80%2fannounce&tr=http%3a%2f%2ft.acg.rip%3a6699%2fannounce&tr=http%3a%2f%2fvps02.net.orel.ru%3a80%2fannounce&tr=udp%3a%2f%2ftracker.lelux.fi%3a6969%2fannounceI think firearms are way too easy, ammunition has always been the hard part.
>>64550805Ive seen this trick before, its classic. They dont want you to know this, but you can actually use almost any sort of matches to create primer compounds and (a highly corrosive) propellant if you know what youre doing.At this point Im really just after info on how to fabricate anvils and casings.
>>64550815I think they have to be lead or brass, you can probably buy spare casings without a license through the internet if you're from a third world or European country
>>64550815Okay, I'll bite because you guys are very lost.Classic standard casing's can't be fabricated at home. How casing manufacturing works is by stamping brass or other metal into shape using multiple presses which are usually automated. A metal sheet is punched to make coin shaped pieces, which are then punched to form cups, which are then pressed to form rim and primer anvil and anvil hole. And finally pressed into final shape before washing and polishing.This isn't doable without advanced machinery. Alternatives for this approach include casting, which isn't doable without machining because materials expand while heated and shrink when cooled down. This also introduces bubbles in the material, which require very specialized tools to remove. The only option which remains is machining, which I suppose you could do by using a drill as a lathe or an actual lathe.Ultimately this is not doable.The accuracy of ammunition tends to be measured in parts of millimeters. With the accuracy around .001. You will not reach this accuracy by the means explained previously.However what is doable is plastic shells such as the ones used in shotguns. You can 3d print these or cast them from plastic using appropriate tools. An alternative to this is fabricating CTA-style casings either from plastic or paper and (preferably) infusing this with glue or at the very least coating it with tape. This process can be automated using 3d printed machinery and reaches the necessary minimum accuracy. However it makes the firearm in question very different, as standard CTA mechanisms involve moving chamber, actuated by powder gasses. There is speculation that this can be turned back into more of a mass-driven format by cutting the chamber's connecting pieces in an angle, which forces parts of the gun upon firing to push the chamber out of battery, which can be forced back into position with springs and connecting surfaces. But I'll leave investigating that to you.
Do 3dp questions go here? I've been wanting to ask people about the 3DP90 which im very interested in. I dont have a printer myself so I've been looking at buying a kit from 3dprintfreedom but I've never heard about them before. Id love to know if it is FRT/SS compatible since it says something about using a AR FCG
>>64551160Now the simplest of CTA firearm can be manufactured by simply cutting a barrel blank using a electronic wire cutter. It should form a locking pattern on the barrel. You should be thinking of something along the lines of puzzle pieces. After this the breech is machined so it can be plugged to form breech face. The breech piece is machined to a larger hole, to whatever you assume is the width of your ammunition, and the barrel's mouth is widened slightly to help the bullet pass into it. Assuming you're making customized ammunition it doesn't really matter, as long as it's bigger than the caliber. As long as these pieces are held together in alignment this firearm is safe to use at the ratings the barrel is proofed for. For holding them aligned, something like an appropriately sized pipe can be used. For actuating the action, additional mechanisms can be formed into the pipe and breech piece, to force the breech out, for example when moving the outer barrel.When this is done, what it results in is a CTA style rifle's pressure bearing parts. Adding to these is a trivial matter.
>>64551160>>64551187Thank you for the advice, however I feel I should add that making a primer as far as the cup and priming compound are concerned can be achieved very easily.
>>64551271Relative to a novel caseless ammunition system and it's accompanying firearm? Yeah probably.
>>64551271Chemical ignition is superior in terms of reliability and simplicity to any alternative. But there's an interest for it to not be accessible and it is obvious when you ponder on it for a moment. A lot depends on your core principles which start the hobby and the end goals. Are you just a curious tom? Are you a wannabe-survivor? Do you roleplay doctor stone and do it all by yourself? Are you an engineer looking to get into firearms manufacturing? Where goes the fine line of self-reliance and unlawful action? "Why do it when you can just buy X?". This isn't a war effort, you don't need to do chemical primers at home. As for any ignition needs you can use electronics and they're more than enough when you apply yourself.
>>64549287Wanted to make a zip gun recently, can i do it in a day?I still dont get the firing pin thing
>>64551787You probably can make one in a day depending on your skill, materials, tools and the complexity of your design. Firing pin can be a nail or broken drill bit, some especially crude zip guns just use a nut on a rubber band to smash the primer. A closed bolt design would be much safer for someone getting started in backyard gunsmithing though.
>>64551787Oh and keep in mind even in the relatively permissive US there are state laws against privately making firearms and some against zip guns specifically, and federally you could run afoul of the nfa or undetectable firearms act very easily making one.
>>64551821>>64551835Thank you guys!! It's going to be really fun to do it and fun to learn it in general
>>64549287>What tools do you consider essential for workshop experiments?While not essential I find a dremel to be a great tool to have. Whether for opening channels, using the cutoff wheel, shaping, precise cuts, its useful at all levels of building.
only good thread here
Anyone working on anything novel? I'm trying to make the zz version of the 4 banger .32 caliber. Might have put the cart before the horse though, the designer of the zz wasn't able to get enough force in the firing pins, I had the same issue with a 4 banger.
>>64552538>Anyone working on anything novel?Im in the design process for a garbage gunAssuming a person had ready access to 9mm ammunition along with a hacksaw and a flathead screwdriver he should be able to walk through his house and pick out every part he needs to make this gun.
>>64552647Sounds good, single shot?
>>64550525Holy shit, that is genius. Looks like a pretty strong design even, if you beef up the locking/firing block thing. Imagine if you made a centerfire version as a competitor to those Henry single shot rifles for half the price.>>64552538Any more pics? What is it, like a little pepperbox? How are the cases supported in the middle, or are there steel inserts that go in there?
>>64553060Sort of this mixed with a songbird plus some metal, yeah the holes were for sch80 pipe but the size was a bit off in that version.
>>64552882>single shot?Nope.
>>64553238You had my curiosity, but now you have my attention.
I have yet to see one that stands toe to toe with professional assault weapons. Like some mad scientist shit
>>64549358How did he know it would work? he had to be a gunsmith of have at least tested it.
does the sten count? its repurposed factory equipment
Made a very simple slam fire shart gat. Used a ground down bolt as a fixed firing pin. Ended up lodging multiple brass ends in my tibe by over penetrating the primer. Do you guys have any pointers for firing pins material or selection?
>>64555227*Tube
>>64555209You can just go test fire in the woods or in a basement into a barrel filled with foam with some sand in the bottom.>>64555227The end of a drill bit has the right hardness, it also has the benefit of being just the right size for holes you drilled with it. Round the tip and make sure it doesn't project too far and hopefully that won't pierce your primers
>>64555227Firing pin should be 1-1.5mm wide with around 1mm protrusion. Slam bang shotguns usually have a dowel section to occupy the void in the end cap and hold a nail in the right position, did you have a spacer like that in the back?
>>64555209>>64555328Might seem counterintuitive but it's actually far easier to get away with clandestine gun manufacturing and use in a place with no guns like Japan. Most Japs haven't even seen a gun outside of TV and movies, it'd be the last thing they'd expect. That's why when Abe got shot everyone just sort of stood there in shock as the guy started running.
>>64555406Nope probably could add something like that.
>>64555521*Far easier to get away with a clandestine attackClandestine manufacturing is much easier in a gun friendly country due to parts availability and the possibility it may not be expressly illegal.Even the shittiest airsoft trigger assemblies are hard to find in places like Australia, and outside of maybe 4 first-world countries youre practically forced to manufacture your own barrel (if you desire rifling).
>>64555222checkedalsoA zip gun should at least have some finesse to it.This thing is just institutionalized scrap metal.
>>64555083More to come in the future.
>>64555830>This thing is just institutionalized scrap metal.This gun has killed thousands and rivals the AK in terms of simplicity and reliability. It is cheap and easy to manufacture. It is one of the best guns ever made. I have no idea why they put the magazine on the side though; I can only imagine thats a carry over from before WWII where those in charge expected soldiers to be lying down more than standing up.
>>64550129The ryno isn't uberclay's design, he's just doing the beta, the developer is anon
>>64550142I hate that open bolts are not legal to manufacture. Open bolt recoil SMGs are just so incredibly simple.
>>64550632PVC is rather brittle.It would work, but you would need to replace it fairly often. 3d printed guns having a shorter life isn't that big a deal when replacement parts can be printed in hours.
>>64550782>Im Hellbent on building a reliable gun from PVC or worse. Youd cringe to know what else Im going to try to use. Worth noting its not exactly a STEN, just similar.If you are US you can build a "STEN" that looks visually similar but has a hammer and firing pin for closed bolt operation.
>>64551167>Id love to know if it is FRT/SS compatible since it says something about using a AR FCGIt should be obvious from looking at the STL or CAD files. Also depends which FRT, some are drop into any AR FCG, some require a little drilling.
>>64551787>can i do it in a dayProbably, the time if you know what you're doing is very short, but you're going to be much slower when you're learning something new.
>>64555829>Clandestine manufacturing is much easier in a gun friendly country due to it being legal and you can order most parts with your real name and credit card and delivered to your residence via mail or package services.
>>64556044Homeland security will make an unconstitutional note and tell your local police if you do it that way in a state that opposes your right to self defense, but you don't have to buy parts with credit online. You have the freedom to drive somewhere you can pay cash for parts.Now I'm trying to remember if I've ever seen parts kits in person, not that I can recall, I have seen bare frames for sale though. Well you can get a p.o. box and a prepaid credit card.
Bump
>>64556044Officer, those are just for my part kits collection, I wouldn't know where to begin making real guns.
>>64558668There's nothing illegal about having hundreds of firearm parts
>>64558703Unless they're machine gun specific and you live in Washington
Still one of my favorites. Revolving cylinder shotgun from I believe Taiwan.
>>64551160>This isn't doable without advanced machinery.it is difficult, but not impossible. all you would need is a hydraulic press, metal sheet (brass, steel, whatever) and the most important part, a steel mold of the caliber you wish to do. you would need to make the later in a lathe, if you don't have a lathe or knowledge on metal machinery you could order a machinist to manufacture it. again, it is not impossible, but also difficult and tedious.
>>64562457I would say it is difficult enough to be outside the scope of anyone who's not a true euthiatist with engineering and machining skills, not to even speak of resources. When we talk of technologies in general, accessibility is always more important than craftsmanship. The opportunities are unlimited if you're master of all crafts, but very few people are. Very few people have the resources necessary to even apply their skills. And less so in time of need. Which is what most of these things are. Barely minimum viable products in response to time of need.Think it like this. If you have ammunition readily available, you probably have guns available. No need for a zip gun. It's novelty item. If you have no ammunition available, you probably don't have guns available either. Investment into making brass casings is a preposterous for completing a zip gun. If you have to make easily reloadable firearm and you have no ammunition, CTA-style ammunition is the way to go. More pressure the gun is suppose to produce, the more important a proper locking mechanism becomes. The concept explained offers equal strength to the locking mechanism as the firearm's barrel. If you trust your barrel, on paper, you can trust the lock.
>>64564234Is anyone making caseless telescoping ammunition in their garage? Are you talking about fuckboytony's blackpowder ammo? That is sort of viable if you have no outside commerce, but is moot unless you are that one russian. Pretty much everywhere else you can get brass casings as blanks or dummys, you can get ramset blanks for powder and primer and you can make ammo.I'm of the opinion that you have the right to life, liberty and the tools to defend them. You may need those tools someday and it would make sense to make them while you have the opportunity then stash them in case your government doesn't fully agree with those rights.
>>64562015I just saw a very similar 3d printed 410 being tested on odysee
>>64565627Name of the project? Sounds funny
>>64565687The defendant
I wonder if anyone's tried to convert one of those Nerf guns into a real pipe gun. It seems like it'd be easier than starting from scratch, since you'd already have the mechanism. Just put a barrel and a striker pin in there.
>>64566692There is one already posted in this thread, it was built in protest of the frame and receiver rule to prove everything is gun iirc.>>64551835
>>64555970Common misconception. They are legal to manufacture so long as they are designed semiauto. The trouble comes from the ATFaggots making up rules like how they consider anything convertible with 8 hours in a machine shop to be a machine gun. See Fudbuster’s video on open bolts.Honestly the entire open bolt prohibition has no basis in any real law, it’s all “rules” and interpretations made up by the ATF
>>64567770>The trouble comes from the ATFaggots making up rules like how they consider anything convertible with 8 hours in a machine shop to be a machine gun.I'd love to see them try to justify that in court when it takes 30 seconds and a drill press to turn an AR lower into a machine gun.
>>64549287Got an /x/ scenario for you, lads.I got a character trapped in a pocket dimension filled with their own corpses (it's magic shit, when they jump through time there's a mid-point between the start and end, and a copy of them is the one that makes it to the end, they get stuck in the pocket dimension).Now, they only have what they brought with them and their own corpses and magic can't be used in the dimension. This is fantasy so they don't have guns, but they do have black powder, and they want to make it for defence.How do they make it? They can burn down bones for bone charcoal which doesn't have as high a carbon content as actual charcoal or just find wood they jumped with before, and they can ferment shit to get the residue like an old-fashioned nitrary used to do, but how do they get sulfur? Boiling down soap into a residue?>>64555856>I have no idea why they put the magazine on the side thoughBecause they knew it looked fucking awesome.
I've had some issues with printed STEN mags for a DB Alloy and figure someone here would have experience with them.My mags keep spitting out the last two rounds at once no matter what, and they keep delaminating from the bolt impacting at the same point on the right feed lip when the last round is fed no matter how many rounds are in the mag, across 4 different mags. I've printed them all in ASA, should I just try a different material? Is my recoil spring too weak? Is there one mag file that works better?>>64555856The STEN comes from a lineage following the Lanchester, which is an MP28, which is derived from the MP18, which is side-loading because of the chosen magazine (Luger magazines as dictated by the German gov't) and difficulty in feed reliability in detachable mags with the manufacturing tech at the time (1918) from traditional bottom-feed mags. Nothing to do with tactics.The Lanchester was simplified into the STEN, and the side-loading was retained for this reason.
>>64555209How did he know sticking a red hot copper wire into gunpowder would make it combust? That's what you're asking?
>>64572636Things don't always work as you expect, testing is critical.
>>64549287did anything cool come after fcg9 and he machine gun equiv fmgc9.:I feel like3D PRINTING DID NOT ACTUALLY CHANGE SHITyeah bro just-buy barrel-buy bcg-buy pistonsI mean sure can do that, but in a way you could do that b4 just buying p2p.... If you want to do a crime you can also just swap the barrel unless you leave the gun at the scene nothing will happen and if they find the gun on you you lost either way . Sure its cool to bypass the 3d waiting period and not have it linked o your name but you could easily achieve this before.It feels gay and sorta just a more based version of redditors priting figurines and useless shit. Yes its cool but don't act like it liberated us much. I guess you can print some things that send you to jail in regards to uhhhhmmm "fire select" lets say if you get me but you could also sorta make these parts pre-3d printing era with hardware store equip. So:- did someone actively put in effort into producing BCGs lets say or pistons or any metal parts that are sorta difficult to mill?- At what stage are home + affordable CNC's (nobody spending 3k on a ghostgunner lol if you can just buy an used ar and swap barrels)?or anything thats like 0% builds not just lowers n shit. Yeah suppressors are cool too but cmon. I know ppl were making 22 bcgs fully plastic for ar platform BUT its 22 so cmon.
>>64549965Offer some details please anon
>>64574381>did someone actively put in effort into producing BCGs lets say or pistons or any metal parts that are sorta difficult to mill?The nutty9 uses nuts and bolts for the bolt, you just need to drill a firing pin channel that's pretty forgiving with a jig. It's a smart, easy design. There has also been progress in jigs to make more complex bolts like for the rogue9. As for new 0% there are several .22s and in .45lc the modelo polyactico was recently released, and this one seems fully diy too>>64566684
>>64574381You're approaching this topic like you're approaching new iPhones. Like a consumer. Be the one making the change, or wait for Jacob Duygu to fearlessly play deadly games against his oppressive government inorder to produce new plans. No wait, they tried to arrest him and when that failed they murked him.>Huh? So is the improved version going to be postponed?Indefinitely.
>>64570186>Pocket dimension full of their own corpsesOutside of something like Mad God this sort of sounds retardedAlso you cant make anything useful like that. The only thing I can think of is that scene from Blood Meridian where the Judge made BP partially from peoples urine.
>>64574381I'm working on centerfire stuff that requires no "real" gun parts>>64552538It shouldn't be all that hard, globally people are craft building firearms all the timehttps://homemadeguns.wordpress.com/On the other hand I don't really know what I'm doing. There are probably lots of guns that end up not getting released out of caution, failed betas or designs that sort of work but never got to that point.For all the talk of getting away from kit built guns there seem to be relatively few people working on it. Black cat engineering has some, but they aren't popular. I tried a goblin but the semi auto designs just didn't look like something I wanted to give a shot building.
>>64575201If I were to give some thoughts on this, I think the FGC9 plan to introduce US-compliant firearm is a good one. Because that gains popularity, fame and community made improvements. So if I were to give some advice, I think serious time should be spent on designing a mechanism which is self-contained and is simple as an open bolt design, but still is US/EU-compliant.Goal being that it's simple as a zip gun which can act as a generic steel upper with interface, which is self-contained firearm on its own. The 3d printed parts act as a chassis if you will. This gives serious freedom for implementation and scaling.So we are talking about a revolution in how a zip gun would be designed and how 3d printed parts are used in full DIY firearms.This will also make the firearm EU-compliant for the most part, because the firearm is contained in a chassis which is not the firearm itself, since the firearm can be fired safely without it. It simply increases the firearms usability. This approach will increase the actual firearm's lifespan, which allows for those who wish to do so, to register the firearm. And allow switching between implementations. You can have a single registered single firearm, but multiple implementations of the same firearm. Same logic as with pistols and PDW kits for them. This resolves the primary problem with designs such as FGC9, as the parts would wear out rather quickly and you would be in paperwork nightmare or simply doing it illegally if you were trying to replace them. If the chassis would wear out it can be replaced without paperwork, in a similar manner as you wouldn't need paperwork to switch between hand guards.A self-contained zip gun with self-contained firing mechanism and minimalist magazine well. And you put that in a 3d printed chassis with everything else in it.
>>64575376Now I'm going to give some food for thought on how this could be done.Introducing the zit gun concept. A stupid name for a stupid idea. Open bolt, sure, but it's both semi-automatic and full-automatic with interfacing. It's self-contained as explained. All depends what surface is pushed against the disconnector button on the bolt.The tubing(frame) needs to have a hole slot into it, near the very rear.And the bolt simply has a spring powered button in it, which fits the previously mentioned slot. Assuming this imaginary zip gun's bolt would have correct weight to it, it will cycle normally after firing. During this normal cycling the disconnector will get caught in the frame's slot. An angled block would prevent that from happening, hence automatic firing. A square block would get in the way if the trigger were to be held down. Hence semi-automatic firing.Now other concerns would be the extractor, that can be cut and belt from leaf spring steel, and attached how you'd like. And ejector can be a partial square hole cut into the frame which is bent inwards.Now a concept like this can be already implemented the way explained. It is not US-compliant because of the open bolt design, but it shows how this interfacing can be done. I'm sure with some thought put into it, it's possible to make a striker fired variant of this. Hence making it US-compliant.
>>64574381The only things that really fit what you're after are the Modelo Polylactico (rolling block design, uses 3d printed ammo and a 3/8" pipe as its barrel) and successors to the FGC-9.Making barrels at home is prohibitively difficult for anything beyond pistol cartridges for the layman due to chamber pressure and reaming. To go better for barrel manufacturing like is suggested for things like the 3dP90, you need a lathe and a proper barrel blank, and if you have those available, why not build a "normal" gun? That's the problem with your question, there's no point in the middle ground you want. Either it's easy to do and uses premade parts, or it's prohibitively difficult for many and would be better served with a machine shop, and then why make an "improvised" gun if you have that?There's also a few 3dp "smoke" grenades and launchers around; some have seen actual in-field use, and should be considered in this discussion to look into. There's more to "weapons" than guns.
>>64576204There is some development going on for diy rifles, people are working on straight walled cartridges like 45-70 and there are tricks like printing rifled liners for standard pipe. If you press fit one standard pipe in another you could theoretically then print a chambered liner that could fire a bottlenecked round. It wouldn't last long but it's still early days.>>64575376>>64575419This may have made mose sense if I hadn't just gotten out of surgery.

>>64551835That barrel has E.D lol
>>64553238Is this a zoomer meme? Who is this guy?
I think I have perfected single shot designs.The large one uses 9x17 cattle slaughter blanks. 357 magnum levels of muzzle energy.Middle one I haven't fired 9x17 blanks with yet. I plan to when I get the barrel attached with better mechanism. Smallest uses 6.3mm nailgun blanks. I plan to make longer barrel. Should yield about 500-600 joules of muzzle energy with it. Projectile 9mm steel ball bearing. Smallest one has a kick. The other two have nonexistent. 9mm ball bearing weighs 3 grams and at high velocity penetrates kevlar with ease. If you only have one shot better make it count. That's why maximum or nothing.

>>64583474Hydraulic pressure pipe, commonly listed as steel explosion proof pipeIf you are planning on ecm rifling the barrel thenInner diameter 8-8.6mmOuter diameter 16mmIf you are leaving it smooth bore then 16mm od 9mm id and ream a chamber with a flat cut 10mm drill bit to a depth of 16mm, then radius the entrance.
>>64584755Honestly I don't like gaskets. I leave stuff sitting in drawers for years then get upset when the rubber components fail.
>>64575201Yeah, that looks a little, different.
>>64585095That is the cyberpunk future I want to live in, how hard a build is it?
>>64584879Wouldn't you maintain them every so often so that sort of thing won't happen?
>Make metal tubes into holding Large amount of PSI>Connect two of them to another tube that will shoot a Fuck Off huge Slug/spike >Easy to maintain so it will always be readyIt's that easy.
>Make a CO2 bolt gun out of old paint gear.
>>64584856thanks brudder
>>64586868Any time
>>64585158Hi Point would make a killing in Cyberpunk because their guns are unironically way more reliable than their price point equivalents in NC.
>>64551160You're overcomplicating shit.Cases are made in automated machines because you have to manufacture millions of rounds to fulfill the needs of military/police and civilian shooters.But cased ammo existed before modern cartridge manufacturing. The .577/450 Martini-Henry cartridges were made by rolling sheet metal, and the base which doubled as a rim was wrought iron. Obviously it looks like absolute shit and it wouldn't work in semi-auto weapons.But the point is to just understand what you need and design the weapon around the ammo you can make. If you don't need high performance you can compromise on case strength and thus use methods like solder to attach pieces of brass or even steel tubing.The extraction grove can be made with a jig that holds the case and allows it to rotate and a rotary tool with a grinding bit.
>>64590882The fcg9 doesn't have an extractor, just an ejector, unrimmed pipe if the proper ~9.8mm size should work with a primer epoxied in the base.
>>64591071That's stupid. Extractor can be created with leaf spring peace. You can literally just buy a spring steel fastener and fabricate one out of it. Then just attach it with a screw.
>>64591177My point is blowback in that case obviates the need for any rim vastly simplifying case production.
>>64553060>strongit looks weak as fuck wtf are you talking about
>>64591230I get your point. But my point is that fcg9 and the variations sprouting from it are flawed in their design. Considering the design's fame for being unreliable for multiple reasons, it seems like the obvious first improvement.
>>64590882I don't agree with that statement. It isn't complex, it's unorthodox. I agree on one being able to manufacture even shitty rifle ammunition by hand. I don't think it's wise to spend the necessary time to learn that skill. I think it's always worth asking what is the path of least resistance to reach the ultimate goal. That path varies depending on your conditions, but in broad terms you wouldn't want to spend the time required to make one of those casings.If you want to deal with spending around 30 minutes shaping a single casing then I suppose it makes sense. If you're going to be constructing a rifle from the very start with nothing available, you would obviously gravitate towards the CTA-style mechanism. Because it provides you with an idiot proof locking mechanism from the very start, gives you a lot of leeway in chambering, removes the need for extractor and ejector, and offers you a way to manufacture ammunition yourself. Even if you wouldn't want to manufacture ammunition yourself, you still have the option to manufacture sleeves for off-the-shelf standard ammunition. It's forwards compatible. You can have both working on the same rifle with no changes. You don't even need a true and complex firing mechanism for it. You can just use a pipe shotgun style approach for firing it. You can have the chamber rise out of the frame, allowing fast reloads. And that wire cutter? You can do just fine with files, a metal saw and a bit of that craftsmanship. You can do the headspace by rolling the chamber on a surface with a file inside it. Because it is a separate piece. And since it is a real barrel blank, its got the strength. If you do all this rolling block business, you have to consider the mechanically weak points which appear by design.Obviously this is the way to go. And I'm sure you agree with me if you think about it a bit longer.
Can i ask you guys how i'd improvise a drone with a gun idk
>>64593510Like this, but instead of a cooler it'd be a heaterhttps://www.youtube.com/watch?v=NZDYx31nDsI
>>64574858Most of the guns pictured there are released under a non commercial license, could they sue that ghost gun consulting agency for profiting off of their designs?

>>64549287Can anyone recommend a cheap, basic 3d printer to start practicing with? I’ve never tinkered with one, so I’m a total noob at the moment, but I think it might make for a fun hobby to refresh my interest in guns. Obvious considerations would be a large enough size for certain parts, and no hardware restrictions or backdoors for the spooks to see what I’m making.
>>64599207I bought a Flashforge Adventurer 5M as a starter printer.Flashforge is cucked as a company but their printers are:>cheap ($239 on Amazon currently)>just work out of the box (at least mine did), >can print from a USB so you have no spooky backdoors unless you install oneIf you don't want to pay Bambu prices, I'd suggest the Ad5M. Honorable mention to the Elegoo Centauri Carbon, it has good advertised features but I know they sometimes require a bit of tinkering to get running smooth and I have no personal experience with them so cannot recommend entirely.If you want filament suggestions, Polymaker is the go-to brand for filament quality (and they're pro-printing guns). Everyone suggests their PLA Pro to start for gun-related things, it's a good suggestion. And buy a dry box, the cheap eSun one on Amazon (like $35-40) works fine to begin with.
>>64599207Ender 3 was the recommended printer for many years but there are better ones out now. I got an a1mini for $200 and it's been great, if I stick it in a box it prints abs and asa, the only 2a things I haven't been able to fit so far are the amigo grande and the plastikov v4. Not sure how much data they send back to china but I don't let it connect to wireless.
>>64599207A little outside your request but FWIW I'm pretty happy I spent a little more on a P1S. The thing just works, the main thing you gotta ask yourself is if you just want a printer to enable other hobbies or if you are ok with getting and keeping the printer working being a hobby on its own. If the answer is no the bambu is the way to go, if the answer is yes then there are a lot more options
>>64585350I don't even check the batteries in my ligjts, I've got too much stuff for routine maintenance
>>64576594>If you press fit one standard pipe in anotherYou want to shrink fit seamless tubing together. Hydraulic tubing would be ideal. Heat outer tube to expand it, cool inner tube to shrink it. Quickly put tubes together, inner tube in now under compressive stress and will not easily crack.
>>64609464Might be worth trying with 1/4 and 5/16 brake line, I find thermally expanding metals is never as easy as advertised though.
The ultimate in simple DIY weapons today has to be blowguns, since you can get a straight piece of pipe super easily, and the ammo is very easily improvised from scraps.I've heard ideas about using CO2 powered bike tyre inflateers to launch the darts, any other system that could make sense? Even canned compressed air (not compressed air just a hydrocarbon which really wants to change from liquid to air) might be able to drive it harder than you could by breath?
>>64610948You're better off throwing a rock, unless you've poisoned them darts are mostly harmless.
>>64599476How critical is a dry box? I live in the swamp and haven't had an issue with any pla, ptg or abs
>>64615299PLA is "babby's first print material," it's harder to fuck up than get right IMO and has next to no rules on moisture. ABS/ASA are both "dryer optional but recommended in wet environments," PETG is "dryer highly suggested."Nylon and TPU absolutely require a drybox to print though if you want to go beyond simple stuff like PLA pro handgun frames.A drybox will always make your prints better though no matter the material, and since a drybox can be had for less than a Benjamin it's a worthwhile investment.
>>64549287> general #1 wow i am witnessing the birth of a new generals thread, thanks op
>>64555209because asians are smart.next
lllllets see if this one been posted yet
>>64549287Why are they called "zip" guns?
>>64622863Chinese ai didn't know, and it had some suggestions for things to do besides making guns.
>>64622863Probably since it was quick to manufacture or a sound they'd make
