Shit ton of work went into that, impressive. Very overbuilt for a .22 caliber firearm if the placard is to be believed.

>>611533

Why in .22 ?

I mean the most common caliber in Europe is 9mm.

Feels like a child of a dystopian hong kong. AKA: hong kong

Also, while 9mm may be the most available europe wide. .22 may be easier to get in kurwa land.

Speaking of India, I remember a thread on an Indian weapons forum some years back where a police man posted the contents of their weapons storage at the station. It was an amazing assortment, all sort of Lee-Enfields, Webleys, a Webley-Fosbery, .476 Enfield revolvers, Sten guns, Bren guns, Thompsons, Greener riot guns. It was an amazing cache that will die on that continent thanks to their strict gun laws. They're still sitting on piles of Ishapore 2A1s that I wish they would send to the US. Another fun fact, the last run of .303 British chamberd Lee-Enfield No.1 MkIII's was made in the 1980's at Ishapore during a rise in tensions between Indian and China.

Nice. I am torn on the music.

I wonder though: did that guy not use any coolant for his tools? I know some people don't like to use coolant because it's a hassle to clean, but not cooling your tooling make you look like a drooling retard.

>>612041

It's a manual machine, you're not cutting at sanic fast SFM, it's really not necessary for low intensity work. Plus, not everyone has the whole setup of pump, nozzle, basin, filter, et al. I would've at least used some cutting oil when chasing the threads, though.

>>612050

You don't need a whole setup for some coolant, just an old gatorrade bottle and a bowl.

Do you mean manual as in hand-cranked, or manual as in non-comper-assisted? Cooling can certainly be useful for the latter too.

>>612216

I mean 'manual' as in a non-numerically-controlled machine that may or may not have a power feed. Not unless we're talking about something like a 19th century treadle lathe.

And yeah, you can apply coolant with a spray bottle or similar, but in my experience that tends to turn it into a three handed operation.

I may sound like a purists but god damn the only thing I would weld shit on is the receiver.

Very nice, thank you.

>>611625

y'ave a loicense for that pasta?

Does anyone have information on the topic milled vs stamped vs welded?

Milling is the most expensive but accurate way, stamped seems to be a middle way and welding everything together is pretty much the most "ghetto" way.

Is there any gun where most parts are stamped?

>>613243

>Is there any gun where most parts are stamped?

You never served in the army, did you?

MG42 and MG3

Alle Sturmgewehre

The G3/CETME and derivated (MP5)

Early AKs

The Volkspistole

SA80 used lots of stamped parts as far as I know

Also: you got your terminology all wrong.

Milling and Stamping are forming processes. You use them to form a part of a certain shape. Welding is a connection method. You use welding to connect two or more pieces.

>>613259

>MG42

>going full retard

>G3/CETME/MP5

>AKs

I already knew that.

>Also: you got your terminology all wrong.

>Milling and Stamping are forming processes

Nope, Nope.

For AK receivers and G3/Mp5 receivers you can just stamp a metal plate to get a receiver and press them in form with a jig.

For an AK Receiver you can actually mill just 3 plates of metal together.

While making a M4/16/Ar 15 Receiver you have to mill that fucking thing it out of an piece of aluminum.

Or is there a stamped M16 Receiver I'm not aware of?

>>613268

>mill just 3 plates of metal together

you what

>>613270

Sorry I meant welding.

>>613280

I think what he means is there are three methods of construction of receivers. While welding isn't a shaping method it is a distinct method of construction so far as firearms go.

i found this, what do you think of the method of creating rifling, /k/? There's been a few discussions about homemade rifling but no mention of this method.

weaponsman.com/?p=38241

>>614622

Yes, concealing them would be your main issue due to length, but they'd be excellent hand load and blunt impact devices.

>>614623

What if you walk around with them like you're trying to lose weight?

>>614630

I'd ask why you don't have wrist weights instead

>>614637

Wrist weight would make excellent handload devices as well but wouldn't be as good a blunt instrument as the dumbbell.

>>614647

True, but they're easier to explain than dumbbells when you're out and about

>>614608

As I understand it, you are basically inserting a steel rod into your barrel that seals the walls off, expect for the places you want the rifling to be. Then you pump salt water through those holes and hook it up with a weak electric current. This makes the metal rust away in the spots where it actually contacts the water, leaving you with a very shallow rifling.

Looks easy enough, and very easy to reproduce reliably. Making the insert would be the hardest part, and the fag in the link you posted (as well as his sources) use 3D printed inserts. You could just take a rod with a rectangular cross section and twist it to get the same effect.

>>612891

What was the result of mating real slides with fake lowers?

>>620191

They had to add some steel parts to keep the slides mated, but they worked.

From 10 to 150 rounds tested.

Some survived 20rounds before braking, some more. But what can be expected of a 15usd ABS airshit lower?

The more expensive glassfilled nylon stuff survived better (because airshitters want similar polymers to "real steel").

I used to take a needle and put it in a mechanical pencil in place of lead. While it can break easily and won't do much damage, it is easily disguised and deploys quickly. I suppose if you dip it in shit or poison then it would be much more effective.

>>622628

Why would you do something so reckless and foolhardy when you can get a perfectly good steel pipe from any hardware store or junkyard in the country.

The only reason wooden cannons were ever a thing is because they didn't have access to foundries or good metal in sufficient quantity.

>>622628

>>624403

fun little bullethose you got there. i like the thumb trigger. This will make a fine addition to my collection. wonder if ill ever actually build them

Do you think ATF would regard the VG1-5 as "easily convertible"? I feel like it would be a good action for a homebuild semi-auto. I plan on using an AR-15 trigger pack since that pleases the ATF and they're cheap and easy to find. I just feel like the unlocked nature of the action may make the Feds antsy. Did Ian's vaporware VG1-5 project need any mods to get BATFE approval, or had they gotten to the point of requesting approval yet?

>>631887

I didn't say they were illegal, but BATFE is an inconsistent son of a bitch that is intentionally vague about "easily convertible". The only criteria I know of is no open bolts, but plenty of closed bolts have been given the no-go for whatever reason. Constant point of consternation for semi-auto builders working off of obscure parts kits. Then we can all remember the whole shoe string debacle. Or the time they seized a bunch of airsoft guns. I just know the a blowback firearm of any variety is tends to be more mechanically pliant in this regard than a locking action.

>>631999

>plenty of closed bolts have been given the no-go for whatever reason

You're going to have to link them, because they're more heavy-handed on fire control groups or the ability to attach an FA FCG to a firearm.

>>632019

What I had in mind is most of your machinegun parts kits build where modifications are required to prevent the insertion of full-auto internals. This generally includes unmodified bolt assemblies. Even lacking such internals, and lacking the ability to fire automatically as such, they'll still land you in hot water. Your reduced ID tube guns and anything that requires a denial island fall under that. Oh fuck it. I'll build the damned thing and they can come get it if they want it that bad.

>>632028

"Land you in hot water" is in reference to using a receiver that, even if constructed for semi-automatic fire, can still fit enough original internal parts to displease ATF. Whatever line that happens to be, but fitting the original bolt in a semi-automatic sten, Maxim, or M1919 is a known no-no regardless of the firing style of the end product.

No death penalty, you'd get 20 years Federal prison. Lots more info in stickied pdf thread in catalog. It will be difficult to make good guns without tools. Getting even just a drill press would help greatly.

>Lost-wax casting

I thought of an less time and work consuming way.

>>635708

Half the point of lost-wax casting is that it's less of a pain in the ass than making green sand cores. Plus you can cast in undersized holes and threads to save you having to locate them later.

>>635708

If you want to minimize the overall work required, then lost-foam casting is even simpler, as you can leave out one step: https://en.wikipedia.org/wiki/Lost-foam_casting In theory you can use polystyrene in a 3D printer, but I'm not that knowledgeable of that witchcraft.

>>635712

>In theory you can use polystyrene in a 3D printer, but I'm not that knowledgeable of that witchcraft.

The polystyrene that you use in a 3D printer is solid just like as if you were printing with PLA or ABS/ASA.

One thing which isn't immediately obvious when it comes to lost plastic or lost foam methods is that you need to be sure that you have gotten rid of all the material before you pour the aluminium. The reason being is that aluminium likes to react with carbon rich materials to produce aluminium carbide which is brittle and will ruin your parts.

>>635692

Given that 3D printed plastic ones hold up just fine a cast one would probably be fine as well, the only real load on the lower is where the buffer tube mounts so if you want to be safe maybe cast one of the designs the 3D printer guys came up with as they are reinforced in that area.

Black powder for a muzzle loader.

An amateur trying to make anything smokeless has a good chance of blowing himself up, given that the entire process of making smokeless powder essentially boils down to converting highly sensitive substances that detonate into a less sensitive substance that doesn't.

BP is about taking materials that are fairly inert on their own and turning them into something that isn't. It has risks of its own (it is gunpowder, after all), but it is not the same kind of risk.

>>643273

Black powder shotgun shells. The shells are fairly easy to load and crimp, and the smooth bore of a shotgun will be more resistant to fouling.

This will make gas-operated guns a no-go, but most shotguns are manually operated repeaters anyhow.

>>647287

It might be possible, but your depth of cut would need to be so shallow that it would take many hours to complete an operation. The feed motors would probably stall if you tried taking much more than .005 per pass.

You really can't get away from the need for proper machinery if your ambitions go beyond one or two small jobs. The ideal thing would be for a /k/ommune to acquire a nice machining center, but even something on the smaller side like a Haas mini mill is going set you back 40k. Jet has a few smaller machines that go for between 20 and 30, but generally the least expensive way to go is a used machine from craigslist (2000-3000) to rebuild and retrofit with ball screws, servos, and a controller. Regardless, when you factor in the cost of tooling, you'd be hard pressed to cheap out.

>>647802

I recalled this thing reading your post, r8?

https://en.wikipedia.org/wiki/Multimachine

http://opensourcemachine.org/

>>647802

I don't understand the common infatuation with CNC, nor the assumption that it's a prerequisite for anything. The only time you absolutely need a CNC is when you want some arbitrary oddball contouring that you can't do by hand, or else if you're tooling up to produce a million or something. For anything else, and especially for small scale fab shop one offs, a manual Bridgeport is more than sufficient.

>>647287

>Can i build a lower receiver with this shit?

No, machines like that are barely stiff enough to do UHMWPE.

>>647815

Its not a case of absolutely needing it in order to make something (although as 4th and 5th simultaneous axis machines become more common more designers will make crazier designs which will require it) but instead the increased productivity that comes from having even a low end CNC machine like a Tormach.

Sure, it might be simpler if you are just taking a planing cut across a piece of metal to have a manual mill but for even small jobs its becoming more advantageous to have a CNC machine. Modern tooling like high feed endmills also need feeds and speeds which are beyond what a human can do.

Hell, even race teams are investing in big CNC machines since billet engine blocks are becoming popular to the point where teams that aren't using them are at a disadvantage in racing leagues where they are legal.

>>647835

Leave it to an engineer to look at a pile of junk bolted together and think "ah, precision machine tools." It's better than nothing, but forget about holding tolerances, especially with extended use. Unless of course you go to the trouble of lapping and scraping every mating surface by hand.

>>647815

It's a prerequisite for cutting any sort of complex profile without possessing superhuman qualities or taking many hours of work.

CNC is the difference between spending five minutes setting up for an operation, and running it in 15, and spending 15 hours machining manually.

>>647958

The cylinder holes used in that example are actually extremely durable. Depending on your weld quality and the tolerances of the axles you used I estimate that you can have the same accuracy for at least a year of continued moderate use.

I am not saying anything about the initial accuracy though, because it depends entirely on the axles you use and the quality of your craftsmanship.

Heres a good tip on how to make firing pins easily

Use a dremel like a lathe

Thats it; it goes retard speed if you want it too, its small, its cheap, and if you want to just shit out some pins without a care, you got what'll do it

>>662762

Of course you hypothetically could

As long as its hypothetically combustible & hypothetically in a container with a hypothetical ignition system & a hypothetical one way exit, you have a hypothetical cannon

Hypothetically look up the hypothetical potato cannons hypothetically made of metal, they are hypothetically very powerful & hypothetically actually safer

You can also hypothetically use propane & / or butane as your hypothetical fuel

>>662844

I know that propane is explosive when mixed with oxygen but I don't think it would have the same power as hydrogen. I was doing some research and found that the US navy uses hydroxy mixture for some artillery so it's probably a better propellant.

>>647353

Fun fact, buying a block of aluminum that size is surprisingly expensive and when I looked it up it cost more then just buying a 80% repressive unless you were buying in industrial scale bulk.

The only cost effective way doing a 0% one is to hunt down scrap aluminum and cast a blank yourself. Cuts down the price to the point that can compete with just buying the almost complete lower.

Looking for the drop-in auto sear for the AR that was like, a block of aluminum that you didn't have to drill a 3rd pin hole for. It was like a concealed system.

Anybody know what I'm talking about? I might be imagining it.

A lightning link, though that isn't a block at all and iirc only work with some AR's.

>>677417

>Oxyacetylene would probably also work but be careful if you try any of this stuff.

also no, it burns hot but doesnt expand enough. most people who get into hardcore hobbyist potato cannons still swear by flammable aerosols or butane. they offer good expansion, are cheap, and are safe to handle.

ps

>hydrogen

also offers fairly poor expansion and energy density compared to more conventional fuels. hydrogen is used in some combustion engine based generators because… uh… reasons, i guess. but there's a reason gasoline and diesel are more popular

>hydroxy

literally pseudoscience quack shit for retards. hydrogen with enough oxygen to burn is already "hydroxy" but without the pseudoscience quack shit. there are optimizations to be made in your fuel-air mix but "hydroxy" in its usual definitions is different from hydrogen and oxygen happening to be the same place and is, again, pseudoscience quack shit for retards.

if anything, a more viable thing to what you want for a gun to use in some kind of insurgency situation would be a hybrid diesel-air gun. some people already do it for funsies with normal air rifles, but basically you put some Vaseline Or Something in the skirt of a pellet and the rapidly increasing pressure causes the Vaseline Or Something to literally diesel and burst into flame, slightly increasing the muzzle energy by introducing conventional gas expansion by burning something quick-burning. it can also happen with freshly but very sloppily oiled air guns.

it's generally ill-advised because most off the rack airguns aren't built to take much higher pressure than they already use so you can fuck up your seals and such, most fuels that cooperate nicely enough to use aren't very good (e.g. vaseline will stick in pellets but will not actually burn that quickly or result in a ton of expanding gas, liquid oils won't stay in place nicely and could get into the bore and impact accuracy, etc), and in general it's trivial to get larger energy gains out of a combination of a larger pellet with a larger piston or stiffer spring or higher pressure tank and regulator or whatever than out of using such a hybrid system and trying to float just under the speed of sound rather than trying to shatter it (and usually failing) by converting your air rifle to a shitty version of a firearm. but it's a lot of fun because it produces a loud report and a teensy bit of smoke like you have a real gun :)
