I dream of a diy gun. Mag fed pump action. Bolt together reciever built in layers like a masterlock. All steel rifled shotgun adapter barrel held in place with hardware store pipe adapters. Hand carved or 3d printed handles. Able to be made with simple hand tools. Still working out the details.

This is the "critter gitter". It is a well documented project. Straight blowback semiauto in .357 mag that takes deagle mags with a surplus barrel. A 10 mm version that takes glock mags, a short barrel and wrist brace is on a personal bucket list. Not just to have but to have built from scratch kinda bucket list.

It's a singleshot 410 that you have to screw and unscrew the barrel to load it, made it in about 3 hours, the only power tool used was a drill and the barrel is made out of some couplings I found at my local hardware store. I don't have it now because the wood cracked after about 2 or 3 boxes of shells

Nice! Never done a pistol yet. A single shot autoeject blowback .22 has always caught my eye. Here is a shot of a personal version of ye olde slam bang pipegun. If you look close you can see its a twist snap not a trombone style slammer. Gives much more accurate shots but I can't do the flip the barre,l reload and blow out the old wad trick with it. however it is very easy to swap out barrels. Good for survival hunting/ casual plinking this way.

That's intended to be a shotgun too. Made from 3/4 inch pipe. More 3d sketching that a prototype. Just never saw any good "hardware store" bolt actions. Lets be honest. Still haven't. But it was time well spent in a shop with trash. Still think there is a secret sauce with plumbing pipe and caliber adapters Luty would be proud of.
>>
>>41425215
The most important thing is to make sure it shoots and that it won't explode in your face. Looks doesn't matter. Just remember two things when building homemade stuff. First don't try to improve something that already works fine and second don't expect it to work from the first time. That's what my experience has taught me.

haha thx, first gun was a slamfire pipe gun with an screwable "firing pin" so to say, in case ammo gets stuck i can unscrew it and clean the pipe. Same ammo. for the revolver i can use the axis as an ejector since its 7 same sized pipes welded together. Its probably not a revolver but a pepperbox (actual pepperboxes are rotated and single fire, not like volleyguns) took some figuering out until i got it right. wanted to make a barrelbreak revolver first, but researching ammo made me realise its safer for me not to have a barrel behind the cylinder since i could get chainfires with this ammo, you can see sparks going everywhere.

>built in layers like a masterlock
How is that better than using a pipe?
>>
>>41425381
My bad I was responding to the wrong comment. That was in regards to the bolt action pics. When it comes to the twist snap shotgun its about as safe as it can get. Double wall black pipe (barrel + receiver), carriage nut pressed into pipe used for shoulder stock. Recoil drives straight back into the stock. A solid steel bolt with a firing pin brazed on for a breech face and a steel bolt straight through everything locking it all with the handle. No pipe thread cap BS here! There is not much that can go wrong with it. The twist snap even lets you move it around loaded with confidence it wont go off if its bumped.
>>
>>41425491
Hard to cram a reciever, magwell and trigger system in a pipe alone. A layered bolt together receiver can be built layer by layer with handtools. The idea is no weld or lathe needed design. There is an AR design already out, can even be 3d printed. Lower calibers need some attention too.
>>
>>41425491
its only better cause this guy doesnt have a access to real metal supply or tools so hes making do with some random thin piece of scrap.
even his reasoning is questionable oh you cant fit all that in a pipe. why not? different size pipes exist. just buy a bigger pipe.

DIY weapons made from scratch are interesting shit to see how resourceful people can be.

But unless you are desperate to have gun to hunt for food or something, I wouldn't recommend actually doing anything more sophisticated than i.e. single shot shotgun from really thick walled plumbing pipe.

Guns are not watches or pens, if something goes wrong it is likely to go boom in users hands. And hospital staff is required to report things like that.

Ok if you have proper knowledge, skills, tools and materials, but it's not really DIY at that point.

I've had a few things tinkering around. This is a simplified STEN pistol, with a wooden lower and pinned in barrel AK style.

The bolt might be the hard part to design because of it being blowback, but I'm sure there are real world illustrations that can be found.

Also, the ejector would be screwed in like on a Moseberg 500, or maybe an 870.

Locking breech 5.56. The picture is self-explanitory. Bolt handle locks into a recess in the upper. The spring might need to be in the rear of the receiver, though. And also figuring out a proper side plate to coordinate the bolt throw.

Salve, my fellow hobbyist!

I had the same problem when I was underage. The only alternatives I can think of is powder from blanks (higher pressure level, so be careful) or ground up matches mixed with the striker compound (but not ground all at once, it will explode on you)

I mean, black powder is basically part fuel (charcoal), part high-explosive (sulfur), and part low explosive (saltpeter / potassium nitrate)
>>
>>41431639
sulfur isn't even an essential part for black powder as long as you can figure out a reliable ignition method, which makes sourcing the stuff even easier
>>
>>41431639

Hey! Thanks for the tips!
Armstrong loads are a thing i'm working on, but i didn't even considered blanks to be an alternative until now.
I'm also thinking about a caplock with homemade percussion caps, that would be more fun to use than a fuse as ignition method.

Also what are you thinking about a caplock falling block rifle?
>>
>>41425394
>It's not rocket science
Ammunition literally is.
>>
>>41431786
I don't have much information on falling blocks, but I think it can be done if the space between parts is as airtight as possible. And with a way to lock the lever in place, like on a Sharps rifle or a Winchester 1895.

As for musket caps, I've heard about guys using soda can material and putting a toy cap on it (if you have access to Strike anywhere matches, the white compound is a decent substitute). You can also just use the cap itself, if it's a cupped type that goes on a toy revolver. But the primers are corrosive, as a word of caution.
>>
>>41431833
Not him, but I can agree with that. Especially if you're wanting to fabricate bottlenecked casings. And don't get me started on magazines.
>>
>>41431786
If you can easily obtain blanks, just use the blank cartridge case and primer as-is. Take the blank powder out and replace with black or armstrong. Either seat the bullet in the case (restricts you to same caliber) or just push a wad in to keep the powder charge in place, and load the bullet and charged case separately. Possible to have a large bore and small chamber -- muzzle-load the bullet/shot, breech-load the propellant charge.
Or a small bore and large chamber -- you'll need a tool to seat the bullet through the chamber into the barrel throat, then chamber the propellant charge behind it.
>>
>>41431866
I would use a magnet to lock the lever, and i would use probably a firecracker, to stay light on pressure
>>
>>41424349
ITT
/k/omando meme magic
>>
>>41431915
I think I'm seeing what you mean. Kind of like a gallery load or 22 CB. That wouldn't be too bad of an idea.

Also, if we're talking about a caplock, I don't think the block would need to be under much pressure because the end of the barrel pretty much seals it up as is, with the exception of maybe some slight gas let-off softly blowing at you (hence the falling block part, and not a 100% inline gun).
>>
>>41431967

That's the main thing to not have access to actual ammo. You need to be a lot more creative with the designs
>>
>>41425215
One idea I found was that 1/2" inch pipe can actually accommodate a 28 gauge shell with slight reaming of the chamber. Almost a better chamber seal than 3/4" pipe to 12 gauge.

And the recoil of a 28 gauge is somewhat similar to a 30-30 Winchester (10-12 ft/lbs of recoil)

What I've noticed with revolving designs is that it's a bit easier to fabricate one from a single piece of round bar stock, with a drill press and a dremel. I think I saw handmade guns like that in a Russian film before (Brat 1997 with Sergei Bedrov)

A harmonica pistol would be pretty cool to see too.

Bet they could sleeve the whole top half in a thin tube maybe a machined flashlight body (maglight?). A dip of black plastic dip for the handle and its about spot on.

They didn't put a measured length of fuse in the touch-hole and light it 10 seconds before they expected to shoot; they used a slow match to light the powder in the flash-pan or touch-hole right when they wanted to fire.

Stupid fun. The mini matchlock works by that same principal mostly because at that scale the small chunk of fuse acts as the powder in the pan. A bit of incense is used as a slow match and flash cotton for propellant. Shoots .177. great for a shoe box shooting range.

I'm basing it off this guy idea sort of, but with the breech and barrel on the side of the main tube. That way I can have a vertical magazine coming up into the breech. Gonna be funky as hell, but should be cheap and easy to build (once I get it tuned and somewhat reliable).

Just googled and found this... but we already knew cowboy pistols were great for SHTF. Gonna add these to my order someday when I get one.

Notice how the blank is offset so that the firing in the rimfire pistol still hits it. I wonder if a centerfire firing pin could reliably set it off from the other side (center of the adapter). Maybe rounds like this could be made to fire in a regular center fire gun. Brass is pretty easy to machine, you can even mill it in a drill press with an x-y table, long as it's the soft kinda brass o'course.

>Maybe rounds like this could be made to fire in a regular center fire gun.
That's exactly what those are intended for, you put them in a centerfire revolver to shoot rimfire blanks. Only works at.45 caliber or more, and that's with .22 blanks. Bigger for .25 or .27 blanks.
I'm sure those would also work in a .45 rimfire gun, but there aren't many of those, and they're generally valuable antiques that collectors don't want to shoot at all, even with blanks, so they're not really being made for that market.

Similar cartridges have been made for .32, .38, and .41 rimfire revolvers and derringers, to shoot a round ball using a .22 blank and optionally some black powder; I'm not aware of them being commercially available, just produced in small quantity by the people who have old guns and actually want to shoot them.

If you were to make a pistol caliber carbine, is there any reason or advantage to go with a gas impingement or piston system over straight blowback? SBB is obviously the most simple, but for a PCC, is there any point to deviate away from it other than because fuck you I can and I want to?

Weight. Direct is simple, but you need the right weight and results can be, bad for you if you skimp.
>>
>>41454029
With blowback, and assuming straight-walled cartridges and negligible friction in the chamber, your bolt recoils with the same momentum as the bullet. The only way to reduce bolt velocity is to increase bolt mass, and vice versa.
With gas-operated actions, you choose how much energy is imparted to the bolt group by selecting the gas port size (or adjusting the regulator, if present), so you can make an independent choice of bolt mass, then set the gas system to cycle at the desired velocity.

In something like .22LR, there's no point -- the bullet's momentum is so small you wouldn't really want any less. For 9mm, though, you really have too much momentum, so you either wind up with high bolt velocity, or a heavy bolt. You can get reliable operation either way, but you'll have a more pleasant gun to shoot if you use gas operation or delayed blowback to reduce the bolt mass while keeping bolt velocity low.
>>
>>41454029
>>41454602
Additionally, if you're lazy/don't have too much equipment and don't want to go through the whole system of creating a proper locking system for the gas system to unlock and move, you can use the comparatively simpler system of gas-delayed blowback. Vent the gas from the barrel into a separate chamber somewhere (such as right behind the bolt) so that the gas pressure forces the bolt forward. After a while, the pressure will drop enough so that the bolt can move backwards and go through the rest of the cycle.

Main issue here is sealing the chamber that you use, also said chamber gets hot.

A single piece, made of a bolt and long nut and broken drillbit (and soon a bolted on steel slat to engage the FCG.) It goes into the tube above it, and the pin goes through the nut there, because this a striker for a legal semi auto pistol/carbine, and not in any way open bolt or readily convertivle to such.

>>41463024
So the nut is going to be/be part of the bolt face?

>the bolt is pretty much just a capped tube with a slot on the bottom and presumably the charging handle, and the real mass is in the striker assembly, which operates like a normal open bolt semi-auto

that's pretty neat. I think usually the striker mass is minimized to reduce the effect on accuracy, but for ease of manufacture, that looks like a winner.

Just look at an absolute crapload of firearms designs and *exactly* how they work. If you genuinely put time into it, really put effort, you'll have a pretty good base of understanding for it all.

>>
>>41468556
>How's it meant to work, mechanically?

Best I can guess, a pair of springs put tension on the mechanism that drives the firing pins, such that they want to spring violently forward; drawn back with the hacked-off screwdriver handle, the firing mechanism is drawn back over a detent which holds the tension and which the trigger directly actuates. Now that I think of it, if that's how it works, it works more or less like a crossbow does--though that would mean you'd have to fire both barrels every time, given that I see only one trigger. Hm.

>>41468556
>Remember, simply copying what others have made isn't the same as designing.

After looking at this further, it looks like much of the rim is contained within the bolt face in this design. If that is the case, that's probably very bad as it would leave little to none of the metallic base of the shell to obdurate in the chamber, meaning it wouldn't have a very good gas seal.

This isn't the biggest issue in the world, since your gun is obviously chambered for some sort of shotshell and they have very very very low pressures, so maybe it would function okay despite those issues. Maybe not, though.

Are we looking at the same animation? Because that's clearly a flat-faced bolt, and the shotshell rim is inside the barrel when the action closes.

... you just said it might be okay BECAUSE it was chambered for shotshells, and hence low pressure. Thereby implying that it would be a problem for sure in other, higher-pressure cartridges.

But what the hell, I'll play along. It's not a problem for shotshells, either. Note the non-recessed cylinder in the Raging Judge; the rim of any cartridge, shotshell or not, is exposed in the cylinder/frame gap.

Now that this thread is still up, I did a revision and found that you can also make this into a poorfag version of a Chiappa Triple Threat.

The bottom barrels will probably be fired via AR trigger groups, and the top will be just a piece of flat metal bent into a hammer.

And it might also be made into a 4 barrel version too, depending on how good you are at mounting barrels and timing the hammers.

It depends on the cartridge case construction, and the pressure it's operating at. In general, you want the barrel supporting the case radially all the way back to the web, and the bolt supporting most of the base axially. Radial support for the web itself is usually not needed, although at very high pressure it may matter. More often, support is provided in this region to support the case wall as the cartridge is partially extracted; you see this in actions which extract while there is high residual pressure, such as blowbacks.

In most cartridges, the case wall gets much thicker toward the head, and sometimes radial support in the region immediately above the web is limited, relying on the heavy wall to keep things controlled; for example, Glocks in .40 S&W notoriously have a generous feed-ramp cut that removes some radial support at 6 o'clock, resulting in bulged brass in a characteristic "smiley" pattern in the next post. (If the case wall here were as thin as at the front, it would blow right out.) In early .40 Glocks, this unsupported region was even larger than in current production, and this was part of how the "glocknade" meme arose.

Axial support is also often incomplete; depending on the bolt/slide design there may be a hole for a plunger ejector, or a slot for a blade ejector, and possibly a slot for the extractor as well. These are generally not an issue -- the case head is generally plenty thick enough to transfer the load to the areas that are supported, rather than having a section of case head bulge out into the unsupported areas. But depending on the pressure (and the hardness of the case head), these unsupported regions may be "embossed" on fired cases.

The width of the chamber has to be as precise as possible to prevent excessive expansion of the casing (can result in failure to extract).

And headspace has to be as airtight on the back of the casing as possible to prevent excessive pressure from damaging or ripping apart the back of the casing (can result in gas blowing back in your face or damage to locking parts)

Does anyone have more of Wheat's old guides? The ones with Holo in the bottom corner somewhere. Never got around to saving them
>>
>>41474936
One more which I just photographed (yes, with potatophone), these were fired in a Glock.
The triangular mark on the right side of each cartridge.is where it was embossed into the extractor slot; the rest was axially supported by the breech face of the slide. (No ejector slot imprint because that's entirely below the case when fired.)
You can also see feed-ramp smileys in front, similar to the pictures I already posted, but less extreme.

What common cartridges are safe to use in cheap steel pipe?
What's the limit before the pressure gets too high?
>>
Are any modern airsoft revolvers made out of good enough steel to make a proper frame for a real revolver? I know you'd have to change out a few parts and add a real barrel, but I don't know about the metallurgy of the frame.
>>
>>41476982
measure the thickness of your pipe and use the hoop stress equation with the yield strength of mild steel to figure out the maximum pressure before bursting, then divide it by 2 or more to be safe. Proof your barrels by hiding behind something sturdy very far away and firing your gun with a rope.

With that said, shotgun rounds tend to be lower pressure and rifle rounds tend to have higher pressures. This is convenient because a 12ga shell fits perfectly into a 3/4" steel pipe, which is the basis for the four winds shotgun and nearly every other pipe shotgun.
>>
>>41476982
I am working on a definitive conversion chart/infographic. But generally pistol or shotgun shells are safest, as the fellow above me said.

Nice, I'm thinking about buying a cheap one and converting it as well, does it have any potential or does it shoot like trash
>>
>>41481287
dont have access to ammo so didnt shoot much with it, ejection is a bitch tho trying to figure something out since its a pain in the ass to take the cartridge out
>>
>>41481305
You could drill a hole for a nail, so that the rim of the case just overlaps with its head. Put a spring in the hole and tie some thin wire or string to it so that the nail won't go flying. Or if you have actual machining equipment try and make something that won't look as shit.
>>
>>41481229
Nice flag
>>
>>41481415
the firing pin is already fucking strong as fuck that it pierces the rim, im thinking of grind above the firing chamber to insert some sheet metal to act a lever when fired to push out the cartridge

You are making all the stuff I have thought about making, but my access to ammo is also limited, and I don't won't to spend like 100 euros just to make them and then shoot them like 10 times

europoor? try searching for shitty drunktard hunters that would be willing to buy some ammo for you

I would, but were I live owning a rifle or buying ammo for it is illegal, unless you are a member of a shooting range. That's how a got some 22s

>I live owning a rifle or buying ammo for it is illegal
i never mentioned that its legal, i used to get ammo this way but the guy that was selling it moved away and i lost contact

How does one do this? I was gifted some break barrel pellet rifles, so I have a couple extra laying around
>>
>>41481689
I just became a member and I was just taking some rounds from time to time, but I gave up on that, now I'm more interested in building shotguns since I can just go to a store and buy as much ammo as I want. Also it is more fun blasting stuff with a 12g or even a 410 than shooting them with a 22
>>
>>41481719
get a dremmel to slightly widen the barrel and the rest is improvisation when it come to the firing pin

Any way to make homemade percussion caps or something like them to ignite blackpowder?

Probably for .22 lr. I know that some people did it with nicer cap guns

Armstrong mix, maybe?
just make it in small batches if you don't want to lose your hands
>>
>>41481889
This, I saw someone make a percussion cap from a metal side from a fuse and some armstrong inside, all sealed with paper
>>
>>41477096
What about making the frame by cutting sheet metal to shape and bolting two plates together with the mechanism between them?
>>41481886
With .22 you could probably use a plastic frame and it'd hold up for a while

regular matches ground into powder and an equal portion of powder scraped off the strike strip.

Please dont make any of the firearms you have seen in this thread, literally out of all of them, only one looks like it wont end with metal fragments embedded in your hand and face.

engineer here, ignore me if you want I'm just saying... mild steel is not adequate for a 9mm chamber. At least get 4140 or something. Bar stock really isn't that expensive.
>>
>>41482714
>9mm
I would think if somebody knew how to drill out the correct chamber size and shape for 9mm they would know enough not to shoot it out of a pipe.
>>
>>41482798
You would, but here we are. I'm heavily reinforcing my breech regardless.
>>
I can use mild steel for a bolt tho right?

Guns used to be made out of brass you colossal stick in the mud
>>
>>41483239
My understanding is that barrels can be softer (But still hard, we're not talking brass here), bolts have to be reasonably hard, and receivers should be a little harder than the bolts, as a rule of thumb.
>>
>>41483239
they used black powder and no they didn't, brass is a modern fetish due to the ease of machining which means cheap
>>
>>41482933
no, you should more honestly be using the most durable stuff you have for the bolt and the barrel, though to be honest follow >>41483299
advice.
>>
>>41482933
For straight blowbacks, it's fine. But not for locked breech weapons.

>>41483239
Brass can work for certain cartridges, but I think there's a limit, depending on the specific part.
>>
>>41483455
>>41483299
Yeah you have no idea what you're talking about
>>41483624
no brass was used for cannons there is no limit
>>
>>41483652
size has no correlation with pressure, anon
>>
>>41483299
it really depends on the type of bolt and if it locks or not
>>
>>41483652
I'm not sure how. Barrels are usually softer than bolts, which are usually softer than receivers in situations where receivers need to be stress-bearing (Obviously AR's, mossberg shotguns, etc this wouldn't apply to.)
>>
>>41483455
Eh, there's so many copper alloys, and the labels have shifted around over time so much, that I don't think saying "brass" is really wrong, though "gunmetal" or "bronze" would usually be the preferred term.
Anyway, guns for naval service absolutely were made of copper alloys to avoid rust, pic related.

If you stick to the same low pressures as these black-powder guns, you could do fine with, say, cold-drawn 360 brass. It certainly doesn't get any easier to machine than that.
Cartridges below 20 ksi like .32 S&W Long, .38 S&W, and .38 Special would be okay with fairly normal dimensions (do your own math for specifics).
Cartridges around 20-25 ksi like .22LR, .32 ACP, .32 H&R, .380 ACP, and .45 ACP would be pushing it, but doable with sufficiently thicc walls.
Normal pressure rounds like 9mm, just don't. You're really better off finding a way to work with steel.

If you're improvising your ammo using blanks, armstrong mix, etc., you don't know what pressures you're running, and you're best off just going with steel to provide the most safety margin possible.
>>
>>41483844
>.38 special

Needs to have the bolt carrier dimensions added so you know how much to trim out of a full auto carrier to make it an SP1
