Is it possible to design a functional semi-auto firearm without using springs?
>>29361328
yeah but it wouldn't be very practical
>>29361328
With magnets
You could use hydraulics
https://www.youtube.com/watch?v=iukCrZLUK78
I would imagine
magnets
>>29361328
Magnet follower upgrade. Gotta unlock it though.
>>29361328
scream at the slide until it obeys you and goes back forward.
>>29361328
air bags might also work. Not well I imagine. Maybe Hydrolics with a nitrogen blatter would work better.
>>29361328
You should first figure out how you make a manual action firearm that doesn't involve springs. I can only think of slamfire.
>>29361328
This board is a shithole.
Thanks for reminding me to stay away.
>>29361328
Someone have a webm of the rubber band AK?
Why worry about the action when you've yet to figure out how to get the magazine to work without a spring?
>>29361494
Gravity fed, baby.
What about a gun that uses magnets to cycle the rifle that uses magnets to accelerate the projectile made of magnets fed from a magnetzine that uses magnets to feed more magnets into the magnetic magnet man stopper.
>>29361424
Nothing of value was lost.
>>29361648
A fully automatic gauss gun, you say? Have to be careful about heat though, I heard that the hotter a metal gets the less magnetic it becomes.
>>29361328

Yes, well, it's designed to use a spring, but it does not need one.
rubber band ak, youtube it
Like a revolver?
>>29361328
yea dude we'll just use magic and glitter and shit.
>>29361733
A revolver has springs.
>>29361328
I can think of a fully automatic weapon with no springs. Give me a few and I'll MS paint that shit.
>>29361328
yes you could use a motor or gravity
>>29361763
nice try ahkmed, we all know that's just a clock
something that you swing around over your head and the centripetal force combined with the recoil of a round firing work the action to spray bullets all over the place in a circle around you
multiple gas ports and multiple gas tubes.
one tube to push the BCG back
the second tube pushes the BCG back into battery.
then for the hammer you have to have some sort of pistol that gets pressurized from the weapon's gas. would have a couple directional valves.
>>29361328
you could make a chain gun with electrically-fired primers. if you can make it extract without a spring (like an internal extractor 1911), i think it's possible.
>>29361626
Gas operated magazines.
HNNNNG
>>29361328
With a bit of modification.
>>29361959
Would those be strong enough to reliaby ignite primers?
>>29361956
tap a small amount of gas from the barrel to go into a piston.
piston would be external to the magazine. So the whole thing isn't 2 feet long.
>>29361328
Yo >>29361794 here. Think double Sputter gun. Feed with gravity magazines and you've got something,
>>29362087
That's good, but you'll still have to figure out the trigger and magazines.
>>29361328
Gast gun like the GSh-23?
>>29362106
There is no trigger. You pull the charging handle on the right bolt with your index finger and thumb and let it go when the left barrel fires.
The magazines are fed by gravity.
Is good gun, yes?
Pneumatics in place of springs. I don't believe hydrolics would work because of the high velocities encountered from cycling, they are optimal during static loadings, not dynamic.
Would be pretty sweet to use I guess. If you are firing a higher pressure round you could simply increase the pressure in the pneumatic device instead of completely replacing it like a spring.
>>29362148
how is the charging handle not going to rip your hand to pieces?
>>29362152
you could do it, using gas from the barrel, but it would be Kraut Space Magic tier complicated.
>>29362087
I had that idea forever ago, but basically like the pistons of a car engine with double magazine that feeds into both.
Somewhat related:
Someone please tell me the amount of force required to ignite a #10 percussion cap.
>>29362131
This would be a good idea. Is there any way to control the fire-rate though?
>>29362175
When you pull the right charging handle, the left bolt goes forwards. When the left round fires, it pushes the left bolt back. The gear in the center forces the right bolt, and thus the charging handle, forwards. If you pinch the charging handle so that the handle gets released when the bolt goes forwards, then the right bolt will load and fire the right barrel, starting the cycle over again.
>>29362203
dont listen to this idiot >>29362261
the answer is 7
>>29362300
Oh alright thanks man ill try 7
>>29361648
Yeah but how does all that work?
If I do, I'll be sure to email it to keltec
>>29361358
That's really damn neat
>>29361328
A piston and tube is all you need, let the air be the spring. Along with a gravity fed mag, you're golden
>>29361422
Make it so that the force of you pulling the trigger is what detonates the primer. You'd have to use very sensitive primers or jerk the trigger for it to work, but I believe it could be done.
>>29361366
Are you referring to 2142 or did another game do that?
>>29361328
Semi auto wouldn't be possible, but full auto would. Just build the mechanism to function like an engine and make it either belt or gravity fed. Now for the real question, how would you design a gun with no springs that would function like a wankel engine?
I drilled out the trigger housing and the rear of my volquartsen target trigger and put neodymium magnets in place of the trigger return spring on my target 10/22.
>>29361328
ayyyy kline
>>29363202
I already got an idea in my head on how to do it direct impingement to move the bolt carrier back and forth. To use gas to pressurize a pistol to drive the hammer onto a free floating pin.
I just need a semi auto trigger/sear assembly that doesn't have a spring.
>>29363233
That is a spring in function.
>>29363202
A pressure reservoir and valves, bro. Pneumatic everything. Magazines, recoil (buffer) assembly, firing pin, extractor, and ejector could all run on air pressure.
You could also use electric cylinder valve solenoids from a formula 1 engine to cycle the bolt. They operate at insanely high speeds, and for 100's of times more per single race than a firearm will experience in it's whole life .
Also, computer controlled bolt cycling could detect and automatically clear stoppages.
>>29361328
depends what you define as a "gun"
It would be pretty easy to make a recoilless rifle without a spring.
>>29362014
Mattv229 did it with an AK.
>>29362892
Sounds extremely unsafe if you ask me.
>>29362087
Or you could use magnet magazines.
Maybe electrically primed cartridges so you don't slamfire it.
>>29363398
>Mattv229
Which is?
What about tapping off some of the gas down a tube to a diaphragm at the base of the magazine, which gets filled up, pushing bullets up?
>>29361494
magnets? compressed or siphoned gas? gravity?
>>29361402
>hydrolics
>blatter
learn to spell you ape every browser has spell check now you hopeless doublenigger
>Hydraulics
>Nitrogen
A gas would mean your system is pneumatic
Holy fuck /k/ is populated by some dangerously idiotic mongoloids
>>29361328
Do those old Gatling guns with the crank handle have any springs?
>>29365460
I want to say yes.
>>29361494
Someone post the feinberg 3d-printed magnet magazine.
>>29361763
That's a korth isn't it
>>29362394
With magnets, man, with magnets.
Would a gravity-fed jigsaw gun work? Just replace the sawblade with a nail or so and put a barrel on it
>>29363273
That's what we're doing dingus, designing springs that aren't springs.
>a passenger plane is just a passenger ship in function
>>29361356
hydraulics use springs in relief valves
>>29361328
easy, just have a return piston that actuates into a sealed volume of nitrogen. the recoil compresses the nitrogen until it absorbs the recoil, then the gas expands again forcing the piston to retract.
>>29361696
>what is hammer/striker spring
>what is magazine spring
>what is extractor spring
ITT: Germans
overengineering and needlessly complicating things when they best work made simple
>>29361328
Rubber bands?
>>29361347
>>29361351
>>29361356
>>29361361
and above all
>>29361424
like, why would anyone do this the hard way?
well, you can use magnets and a piston system re-using both the recoil and gas from firing a cartridge, it would work, but would be larger, slower and much more inefficient, and would need some extra care about what parts to magnetize or not.
>>29361328
Short answer, no.
Long answer, I don't think I could design a manual action gun without springs. You need them to strike the firing pin reliably.
>>29361328
You could use a nitro piston like in some air rifles, but it would be a shit. Best bet would be elastic or something
What if we allowed trigger, striker, and magazine springs... the small ones are okay, but no "main spring"
Would it be possible to design a system that doesn't use a conventional spring to return the bolt forward?
>>29361328
Rubber bands...lots of them
>>29365781
Its to compensate for their low quality steel
>>29362394
Miracles, all up in this bitch.
>>29366901
Germany != Japan
>>29365622
then what is the point?
everything should be a deliberate action of a mechanism. no features that store and release energy automatically.
>>29361422
I think this is why revolver shotguns are so iffy in the eyes of the law.
A slamfire that rotates the cylinder with each pump sounds bout right. Probably could be made out of less than 10 parts.
>>29361328
Coily, I promise I'll take it back!
>>29362527
Mah nigga.
>>29369863
Somehing like a jackhammer but the barrel is connected to the foregrip.
INGENIOUS!
>>29364969
gases are compressible, need hydraulics.
gas operated magazine
gas port and tube from the barrel, i red.
turns the gear, black jew star, that lifts the black L follower.
the blue ratchet mechanism and lever is pressed to release the follower back to the bottom of the magazine.
>>29370929
Doesn't the lewis gun use some sort of clock windup type thing?
Probably counts as a spring but it's not a traditional spring.
>>29361351
But how do they even work?
>>29361351
is that possible?
Pneumatic cylinder sheath around barrel. Second adjusted pneumatic cylinder behind bolt, barrel and bolt recoil together and then bolt returns more slowly due to different pressure in bolt cylinder. Bolt extracts and picks up new round and returns to battery. Bolt cylinder has a cut for a hammer that is linked to a push bar that is pushed with force to hit the hammer into the firing pin. (Firing pin could free float or use repulsing magnets). Hammer resets to rear of action with bolt (decouples from push bar "trigger") push bar must be reset to couple with hammer.
Uses short low pressure rounds for ease of extraction in least amount of space and less wear on pneumatics.
Magazine uses repulsing magnets between mag made and follower, with an attracting magnets at top of mag to keep up the pressure on magazine as distance from base increases. I think this is free of springs and will work. Pls respond I think this is a winning design.

An exercise in engineering is always fun. It doesn't have to be practical to think about it.
Gravity fed gyrojet?
>>29361328
yes
hydraulics
>>29376022
You know, maybe today we have a fuel that would make it actually work.
>>29362175
Gaffer tape a shit ton of bubble wrap to it
>>29361351
Neat idea. I know that magnets weaken with repetitive shock (as in hitting them with a hammer), so the pistol design would probably have to take this into account.
If you had the magnets slamming into eachother with each shot, they wouldn't last long (but I'm no expert)
>>29376107
Maybe some way to avoid the magnets actually being on the receiving end of the force?
Easy, just make a double-barreled belt-fed machine-gun.
The belt removes the need for a magazine spring, the barrels remove the need for firing-pin springs.
You'd need some sort of non-reciprocating charging handle or possibly a pull-cord to get it started.
That's the simple option, if you're willing to go full-German you could make a clockwork revolver that turns the trigger-pull into a hammer-strike with step-up gears, or get totally batshit insane and install a flywheel.
That one faggot on here was trying to make a modular magnet cycling gun.
Haven't heard from him in a year or so.
>>29361328
Yes, but it would require Co2 cartridges like a paintball gun.
>>29376037
A bigger problem with that imo was that those retards didnt use a cartridge and powder to set off the projectile and relied only on the rocket motor.
>>29361366
>that 2142 reference
My negro
>>29369863
is it possible to slamfire a mossberg 500?
>>29361867
This is a neat idea. What sort of pressures would a system like that require though? I assume you'd need some hot loads from whatever caliber the weapon's chambered in
