I live in Germany (gun cunt-roll) so i have to build my own boomsticks. Im no engineer and knowledge on this topic is limited so i have to think of my own mechanism. I came up with this rough design and was wondering if you guys could help me figure it out or recommend safe websites where i can find info on this topic.
You can delete that gas system. This is just a simple blowback smg.
Or you could put in a little bit of effort and wouldn't be restricted to some self-built pipeshit.
Im just doing it for the fun of the craft. Having a shitty slam fire shotgun is still better than nothing.
Here's some TDPs. They have the Luty and the Sten which should be relatively easy to make if you have machine tools.

Stop being gay
Thanks mate 🙂
It's really not that hard to legally get a gun in Germany if you're not a retard or criminal
Im on PrepHole, aint i, so it has to be one of those.
Neger just get a Waffenschein
Im a psychopath. They wont give it to me.

That's probably a good thing. The even better thing is you seem too dumb to make your own gun, let alone ammunition.
Look at the schematics of a MAC-11
i can't believe this shit , criminals can and know where to get guns , normal law abiding citizens have to wait for the police to defend themselves . and then they come to the forums asking for advice on how to start to get their own boomstick , this is surreal ,
in brasil gang bangers can get their hands on ar 15 just like that , normal citizens are slowly waking up from their slumber and thinking , can i make a gun out of a water pipe , how dificult can it be , is it illegal to own a skill saw , and so on , we're doomed like the bible sais the meek shall inherit the earth , that's like saying the cockroaches should inherit the earth
it's a repulsive mindset
Research STEN guns. The parts that are hard to manufacture can be bought on line.
A simple machine shop can be set up to manufacture most of what you need.
Make what you can. Buy what you can't make yourself. Assemble.

Forgotten weapons on YouTube has a number of videos on firearms operating mechanism.
Brandong Herrera is cringe and harldy works on his own design, but nevertheless his AK 50 design videos do a good enough job of explaining the principles and pitfalls of firearm design.
Mark Serbu actually has a successful brand coming from his designs and he gives generally solid info.
Mark Novak at anvil gunsmithing is great for seeing what design problems a gun can have in the long run, as well as a generally good explanation of how guns work.
Your design might work. Depends on the details.
If you're ok with your design using relatively low powered cartridges, like 22 rimfire/most pistol cartridges, or you're ok with a very heavy gun, your bolt design will work ok. It is a design known as straight blowback, where the inertia of the bolt and main spring resists the building force of the cartridgefor long enough that the bullet can exit the barrel and the gas pressure drop enough for the case not to rupture as it moves backwards.
If you want a cartridge that operates at more than 35,000 psi, or has a case volume greater than about 20 grs of powder, you will need a locking or delaying mechanism to keep the cartridge in the chamber during the firing sequence otherwise the cartridge case will burst and the gases excaping will fuck you and/or your gun up. Look up out of battery detonations for images of what this does to guns.
There are many different types of locking and delaying mechanisms. Some of the common ones are rotating locks, tilting locks, and roller delay.
Rotating locks involve the bolt rotating metal lugs into recesses that hold the pressure and then un-rotate as the chamber pressure drops enough for safe extraction. The AR family, AK family, and almost all bolt actions use this system. The M1 Garand family uses this and high speed video illustrates it amazingly well.
The Tilting lock system is where the bolt, Carrier or barrel tilt to interface into recesses that then hold the pressure and unlock to extract the case after firing. Guns like the STG-44, FN-FAL, Remington 870 use a tilting bolt to lock into a recess on the receiver and almost all self loading locked breech pistols like an m1911, Glock etc use a tilting barrel that locks into the slide. This is because although they are pistol calibers, the weight required for a straight blowback system would be impractical for an easily carryable handgun.
The roller delay system uses rollers in the bolt that move into recesses in the truntion(which holds the barrel) and under firing they put the bolt at a mechanical disadvate to make it take a lot of force to open, and is tuned so that they only start having enough inertia to move when the chamber pressure has dropped to a safe level. This is different in that the bolt is not ever fully locked, in locked systems, while they are "in battery" if you pressed on the bolt face, it would not open until the locking mechanism physically breaks, whereas a delayed system, instead creates leverage against the bolt face, to the point where it can support great forces, but will ultimately open. They can still blow up if the pressure spikes too fast for it to open in time, but like pretty much all firearm explosions it's pretty rare and usually has warning signs or is a bad design to start. Guns like the HK MP5 and the Cetme/G3/Hk91/ptr91 use this design.
