How impressive was the homemade gun that killed Shinzo Abe?

Pretty good. Didn't need a machine shop, a 3D printer, manufactured ammo, or any of the stumbling blocks people think exist when it comes to homemade guns beyond propellant and metal tubes strong enough to hold the combustion, and re-purposed fireworks have solved the propellant question. And if the authorities banned fireworks, homemade black powder is a possibility. Same as the gun the South Korean guy used to kill a cop in a standoff some time back.

Good enough for someone with almost no basic tools.
With a welder and angular grinder you can do something far better.

Next difficulty after blackpowder is a primer, but now that airbags are everywhere any 18v battery can pop off a firework.

>>63986219
Electric igniters are super easy to improvise at home. I experimented with this shit as a means of lighting fireworks when I was an insufferable little shithead in my early teens.
Behold this highly advanced and professional CAD diagram.

It should theoretically work just fine to light off a charge of black powder in a muzzle loader.
It would even be possible to pack it into a paper cartridge and stuff the whole thing down the muzzle of the gun, with the ignition wires going out the muzzle to a trigger switch and a battery.

>>63986219
you know almost every seatbelt actually has a straight up blank cartridge in it?
why use a traceable airbag, when the car already a set of rounds ready for reloading

>>63986699
Much advanced, very professional.

>>63986050 (OP)
Velly implessive.

>>63986730
I hope it gets the general idea across. It should be obvious, but both sides would be taped. It's also possible to roll these things up to make them more or less cylindrical.
I tried different propellants, they all worked more or less the same, except for flash powder which was the best by far.
As for tape, packing tape is the best option. Duct tape and masking tape are both inferior, too flame resistant.

Small light bulbs, particularly 12V automotive bulbs in the 5W range, also make for decent electric matches.
But making them is more finicky and time consuming.

>>63986699
When I was little I would break the tip off of christmas light bulbs and stick a piece of blackmatch in them. I made the blackmatch from estes rocket motors and regular cotton yarn.

>Electric igniters are super easy to improvise

why do you even need to improvise electric igniters when you can light off a charge quite easily with a butane lighter?
did you all grow up using only induction cookers or some faggy shit like that?
these things work by piezoelectric charge, and some of these models even have a nice trigger action built in as it is

>>63986700
First time i hear of it. What's it called?
Nice dubs.

>>63986788
How exactly would this proposed BIC-lock firearm of yours work?
An illustration might be helpful.

>>63986800
They're called seat belt pre-tensioners.
Old school ones have mechanical mechanical primer ignition, works like an impact fuze on a shell.
A weight with a firing pin is held back from the primer with a spring, during a coalition, the inertia of the weight causes it to overcome the force of the spring and slam the firing pin into the primer.

Modern ones are fired by the same electronic control unit that fires the airbags.
They use electric igniters.

>>63986814
That's pretty neat, thanks for the knowledge.

>>63986806
I use this butane lighter just about daily to cook with, and have in the past used it for firecrackers
(as kids we just used a taper)
but we won't use the butane for this purpose

so I have not myself dismantled these things, but this is an image I found of the piezo igniter commonly found in cigarette lighters
for the BIC-lock you shouldn't need the butane tank and valve, just that black device containing the PZT, the red wire and the shiny metal contact point across which the electrical spark is discharged
I figure you'd fill the "flash pan" of the BIC-lock with powder, as shown in the diagram

>>63986186
My dad used to make homemade black powder flintlock guns for fun, and then he’d sell them later. Miss my dad so much.

>>63986837
I see two major flaws with this design.
1. A raw electric spark doesn't set off black powder ( https://www.youtube.com/shorts/gdHdnnhy5Ro )
2. If it somehow fired, the pressure would just blow the igniter out the back of the barrel

>>63986858
Based dad

>>63986893
Honestly, he was the most based man I knew. He was a welder and used to make all kinds of flintlock guns in his free time. He hated the ATF, would go on rants about them all the time. He hated any kind of government control and despised communists. When the USSR collapsed, he held a barbecue and invited all his friends to celebrate.

>>63986917

>>63986917
Good man.

>>63986699
My drills were talking about improvised explosives during our camp out in Basic/AIT so i volunteered to make one of these with MRE matches and a bit of comm line, they got made when i demonstrated it using the heater pouch from the MRE.

>>63986050 (OP)
>How impressive
If you couldn't make that when you were in high school age your father failed to teach you even the most basic practical skills.

>>63986699
Even that is excessively complicated. Use a piece of nichrome wire scavenged from a heater, hairdryer, etc, or a model rocket igniter.

>>63986186
I mean if you really wanted to you could just make dynamite with glycerin, nitric acid, and diatomaceous earth or peat or sawdust. Then you just need a steel cap with some sort of combustible material to act as a blasting cap. Wrap it in wire you can knotch with a pair of pliers and you have a half-assed frag grenade.

>BIC-lock firearm
Like a touchhole firearm with the grill lighter at the touchhole.

Also a pizoelectric lighter can be gutted and that spark gap moved to the inside of the BP firearm.

>>63987518
Steel wool is incredibly cheap and available in the cleaning section of every single supermarket.
How is nicrome wire "less complicated"?

>>63987643
A raw electric spark can't ignite black powder.

>>63986860
>A raw electric spark doesn't set off black powder
well that saved me a DIY project, thanks
a butane flame would do it however I think
>2. If it somehow fired, the pressure would just blow the igniter out the back of the barrel
gotta reinforce the BIC-lock housing then, or design a flash-pan

>>63987735
>How is nicrome wire "less complicated"?
It doesn't require match heads or tape. It's also more reliable.

>>63987735
>A raw electric spark can't ignite black powder.
It absolutely *can*, let's not pretend this is impossible, it's not very reliable.

>>63987737
You also have to worry about the black powder shorting out the spark gap. That is a bad idea. You should do something else. At the very least you could remotely mount the piezo unit and then run wires to a spark gap in your barrel, that will solve the blow the igniter out the back of the barrel problem.

>>63988448
Could a piezo igniter from a grill withstand black powder chamber pressures? If not could you make a stand off, like a thin steel tube filled with powdered match heads that lead to the actual chamber? That might be a better solution as you could position it like a normal trigger, i.e the tube is inside the handle and leads to the chamber..

>>63988477
Addendum: Could a small one way ball valve solve any issues with the Piezo?

The 'ignition powder' flashes past the value then when the main charge ignites it slams the valve shut preventing back flash.

>>63988477
>Could a piezo igniter from a grill withstand black powder chamber pressures?
Hell no.

> If not could you make a stand off,..
Sure. But why not skip the Piezo altogether? You seem very attracted to it. Why? Battery + switch + igniter is much more reliable.

>>63988499
you don't need a valve. too complicated for no real benefit. Just use a small hole. Think about how a flintlock or caplock guns work. There's a hole straight into the chamber. It works fine because the hole is small.

>>63988512
So piezo+small hole flash pan, basically replacing the flash pan with piezo+ flash powder.

I like the piezo because they are available and if it doesn't work click again. I see your point though, unless the battery is dead then just wait a moment for the wire to heat up.

If you are making something like this you better make damn sure it works.

>>63986050 (OP)
How did the guy made the riflings?

>>63989720
>pellets
>rifling
besides the fact it was used 10ft away

Hypothetically speaking:
Would tungsten ball bearings/BB pellets still had killed him even if Abe wore level 3A body armor at that distance?

Bump

If you take the individual glass cubes out of one of these and just use wires and a 9volt battery you can ignite various things.

>>63986219
But that gun didn't use a primer.

>>63986050 (OP)
pretty decent execution with what he had on hand, would have been more kino if he made a claymore type device

>>63990726
depends on hit location, but soft armor would probably catch anything it covers. pretty sure 3A stops buckshot.

>>63990726
Almost certainly not. Soft body armor is not hard to engineer a solution against but you're not doing it with spheres unless you have an outrageous surplus of speed or weight.

>>63986197

Turns out good enough is all you need.
