Here's the defenition of a gun ("a weapon incorporating a metal tube from which bullets, shells, or other missiles are propelled by explosive force, typically making a characteristic loud, sharp noise.") So think again@@YuhNinja
metal storm uses some type of gun powder to push each round causing a lot of heat that 1 barrel can not handle why metal storm and the gaw rotary cannons use multi barrels but this uses compressed air so it does not get as hot just friction
Beautiful! You might not be able to avoid those shots clustering, unfortunately, if they are caused by vortices - similar to the way that water, when falling, will fall in a steady stream at first, then the surface undulates, which causes it to form globs that fall in clusters. As a pellet moves through the air, in a region which was not previously disturbed, it will create a toroidal vortex in its wake; when the next shot follows close behind, it will be dragged into the wake of the leading pellet; the 'train' of pellets act like a line of Mac trucks on the interstate, drafting behind one-another. Eventually, however, the gun's angle has changed enough that the next pellet is *not* captured; that pellet acts like a new lead-truck in an entrained cluster.
Coming from a more traditional ballistics perspective, my first thought was barrel harmonics, but this seems like a strong theory, especially for low-mass pellets. You could test this by making the barrel axis fixed and moving your target instead, so entrainment would pull pellets in a straight line and could be neglected. Or just use a high-speed camera, which I would think would be easier.
This brought back some memories. Back in the 80’s there was a multi-state hobby group called Hull Busters. Think 3’ scale RC WW2 warships…mounting Freon (yeah, Freon just go with it) powered BB guns & “magazines” w 50-“unlimited” BBs each. Goal, sink each other’s ships (1/32” balsa hulls per rules). Early versions were servo activated single shots. Then someone got the bright idea of using O rings..come to find out the pressure control wasn’t quite fine enough and you’d get say 3-10 BBs squirting out w one servo activation. Then someone said, hey that’s a great thing…just keep the servo open and fire all the BBs in one go..the arms race was on and the ZIP gun was born. Why ZIP? Cause all the BBs would empty out at once so quickly it was almost instantaneous and sound like an extremely short blurp or somewhat high pitched “ZIP”…more like a 10th of the “Z”. Results were rather than an occasional hit, your were likely to see about 3-8” of yours (or adversaries) hull disappear almost instantly. Yes, we had onboard pumps, and depending on class ship & # pumps allowed, what became known as the “penny pump” could keep her afloat, w water streams shooting 3’-6’ in the air, even with huge sections of hull missing/holed. Ah, those were the days. I think there may be a few Hullbusters groups still active at least pre-“virus of unknown origin”. Have a good’un.
Looks like the name may have morphed a bit from “hullbusters”. Try searching for “hullbusters rc boats BB gun” in “$moogle” or duck-duck. Back when I was involved, we only had Usenet not internet, most info was in a monthly newsletter (which I still have, somewhere), I think the editors name was “Fleugal”, he was based here in Dallas in the early-mid 80’s. Don’t forget, in this hobby if you lose (or even if you win!) you might have to go swimming 😁. Yep, auto electronic shutoffs got popular real quick. Hobby was big enough at the time that we’d have regionals & nationals. Popular ships to build were Tiriptz, Bismarck, Prinz Eugen etc. I built the Deutchland (Lutzow). Building materials were Baltic Birch ply for ribs, main sub-deck. Balsa for all hull and vertical superstructures. Each gun had a mini gas (Freon) cylinder (mine were ball shaped), BB magazines were just brass tubing (the entire magazine was pressurized), RC electronics, simple “water detection” switches for pumps electronics shutoffs etc. was amazing how fast the “weaponry” evolved just a few years.

Especially in the multi barrel config this could be really good for close air defence against uav threats like fpv quads or other "loitering munitions" in an automated configuration on a vehicle or defensive position
@OskarHersch i understand itd be alot less energy than powder fired anything ,but even this would fuck up an fpv quad if you could just target it properly in my opinion, one of my hobbies is building fpv quads and flying them freestyle for a few years now, and while I haven't shot at one I'm pretty aware of what abuse they can take and have had to replace many a part ,they are pretty durable sure but that's mainly just the carbon frame everything else like props battery or front cam are pretty exposed/ fragile and if we are talking about russian lancets or similar you would just need to damage its control surfaces which I imagine are light weight enough. Also I'm just talking about very close defence as they get too close just zzzzap em haha I doubt this could have any real accuracy at much range at all
Steel loses energy too fast. Your “close range” would be maybe 50 yards. You would be better off with .22 pistols on a rack cam fired. .22 machine guns exist that have 200+ round drums, a few of those mounted correctly would serve your purpose, easy 500m+ range on softer targets like drones.
It absolutely would fuck up a quad, I have hunted a ton of small game with .177 air guns with great results. Make this a .30 cal airgun and the pellets would carry significant energy for a good distance as well. @@IVAN_ENT
Holy crap man, this design is awesome. I'd like a 6 barrel arrangement on a permanent turret with dedicated generator and air supply for starling control 😁
Have you considered that your firing rate might not be that uneven, but that your barrel might be vibrating at some harmonic frequency? That would explain the vertical spread as well as the horizontal grouping.
Interesting thought. Another resonance possibility; eyeball math suggests that there will be between 2-4 BB's in the barrel at any given time and if they are interacting with each other they might be creating a periodic variation in muzzle velocity. (Easy way to check that would be to have two sheets of target 6-8 feet apart and check if the groupings are different at different distances from the muzzle.)
That's possible. Someone else also mentioned that it could be alternate rotation of the bb's spinning as they go down the barrel causing them to curve in different directions.
Or it could be a pulse forming in the air supply/ammo feed from back pressure caused by rounds not exiting the barrel quickly enough. A bit of tuning with air pressure and barrel length might help?
That is by far the coolest thing I've been a witness to in a long while. To see all the cans exploding while the final can is being hit and the first can is still in the process of exploding so crazy so cool
WOW; great job, this is a really cool bunch of work! A few years ago I rigged up an Umarex EBOS BB machine gun with an adapter and charged it with 800 PSI from a standard remote HPA paintball tank. It does 8 shot bursts pretty fast at 540 fps. Yes of course it has a laser sight and it tears through both sides of an empty aluminum cans from 50 feet. (if anyone wants to go this route; remember to keep the gun oiled or it will malfunction)
Bro don't beat yourself up. You did a phenomenal job. Very impressive I already know you are going to figure out what is going on with the small Gap in fire. Can't wait to see the final results
This is a fair ground side show gun. We used to shoot them at the Royal Show in Adelaide. Was called "shoot out the star" a red star on a piece of paper. If you got the whole star you got another turn.
Super cool. I work for a recycling facility that has 2 optical sorters. One uses 160 MAC Valve, 80 up firing and 80 down firing. The other machine has 64 up and 64 down firing valves. They operate so extremely fast that the human eye cant catch them firing, you have to use super slow motion to dial in the timing of material being fired on. The conveyor speed is around 1000 fpm.
An ultrasonic transducer isn't the right tool for the job. You need something that outputs a bit more power at a lower frequency, like an industrial vibrator made for compacting sand/concrete, or a slightly less industrial smaller version.
great video and project. we studied droplet streams in college and would pluck a droplet out of a closely spaced stream to measure the change in drag and effects from the missing droplet. if you were at a greater range I would suggest that stagger could be aerodynamic vs firing rate. nice work. or an oscillation in the relatively thin barrel?
Something that would be super interesting to try given the mechanical and inconvenient limitations of physical movement could be to put a high voltage on the barrel so that the BBs get electrically charged - can then be slightly deflected by electrodes outside the barrel. This would allow near-instantaneous control along two axes. It might additionally offer interesting diagnostic data by hooking it up to an oscilloscope. The amount of current draw should be indicative of the firing rate
He probably used a phone camera for the fire rate measurement which leads me to the assumption that what you are suggesting is outside the scope of the project.
It may not be the firing rate causing clusters. It may be the sweep motion system which is pneumatic. You have an intertial load when the air cylinder first begins to extend. You hit peak pressure here in the pneumatic system. After that you get a pressure oscillation similar to water hammer in a plumbing situation. Water does not compress, but the pipes flex which causes an oscillation similar to a pneumatic system. If you switch to a hydraulic motion system, and use short tubing, you will see the cluster effects diminish. A cheaper way would be to increase your air cylinder diameter and observe the difference.
I knew where this video was going when he showed the competition to beat design. Awesome idea, i love it. Simple yet highly effective design. You should get in the world record book lol. It would be neat to compare to say a 22 air pellet/ slug in the same design. I know the 22 would probably be slower but can you imagine the ft lbs dropping power of such a thing? I would love to see other caliber exploration with this same design just to compare speed, power and maybe even groupings. This is awesome keep it up.
Well even in current form its already more then enough to stop (or even tear a hole) through person. With that amount of BB`s (that are not even close to bullet in power) it is same as being hit by a truck if spread evenly or with big hole somewhere if they hit one spot.
@@alexturnbackthearmy1907 lt's borderline. It would kill a rabbit but not sure what it would do to a human. Probably leave a messy hole. 9ftlbs isn't much. 60 is sort of minimum to incapacitate a person according to US mil handbooks.
It seems like this would be great for defeating low cost UAV/drones close in, while being cost-effective, might need to scale up the bb/barrels/air reservoir, but seems very doable
@@Chroniclerope maybe. But it would be interesting to see what kind of damage this does to targets other than soda cans, and also if ball bearings at higher air pressures could be used.
What would be really cool would be to see the insides working in slow motion to see what's causing the bursts. Does anyone know if the CCDs in high speed cameras are sensitive to x-rays? This seems like something @AppliedScience might be interested in figuring out.
@@benjaminshropshire2900 the X-Ray source you'd need to use to use to film that is only available at National Labs. You need a particle accelerator to get an x-ray source that bright.
@@RBMK-ym4dm A few quick searches suggest there are man portable, commercially available X-ray units that are powerful enough that they can inspect large steel weldments in a reasonable amount of time. IIRC those systems are *well* into the "don't stick any part of yourself in there that you would mind falling off" power levels an you can get full motion video at exposures below that used for normal medical x-rays. I'd totally believe that you could end up with rather grainy results, but I'd have to call [citation required] on saying you would need national labs level sources to get anything. I suspect some sort of x-ray strobe source synced to the CCD would end up being part of the operation. You might not get high frame rates from that, but even lower rate very short exposures could be very useful in seeing what's happening.

Hopefully some helpful advice. To help with gaps in grouping, round ammo is not ideal unless you can create a spin on the BB. I'm looking forward to watching more as this is my first video of yours I've seen.
this is insane! those BBs from Hornady, those are no joke. there are a few other black coated ones out there, but these are as serious as their rifle rounds. I liked these so much for my two BB pistols, I ordered several thousand lol. I can shoot weeds in half at 50 feet with these out of my Umarex revolver replica pistol. ultra consistent, most other BBs are not and tend to fall out of the rotary magazines and jam.
Maybe shooting burst wave is created by a harmonic wave within flexi-air hose so remedy would be adding some vibration dumpers to the hose or change hose to more rigit one. Nice project, btw. I'm not a fan of instant death weapons but this one sticks out with simplicity and cost.
I have some questions, primarily regarding velocity and dispersion. Since securing single shot data through a chrono will be very difficult, and since it takes time for the pressure to fully build up, do you have any ideas for providing velocity data? I also notice that the scattering on the short range paper target is quite significant. Do you plan on providing dispersion data and approximately the size of the dispersion cone? I'm also wondering how consistent the rate of fire truly is and what causes the variations in the ROF.
scrolling through the comments to see if anyone mentioned it. I agree. It was not mentioned from what I heard. he couldn't possibly be using gravity...(?) with all the air, there must be a charged feed. ...electromagnetic? super bitchin. great stuff.
there's no second hose or container full of steel BB's. He may be feeding it through the air hose somehow. Maybe the "magazine" itself is pressurized. One hole keeps supplying the air while pushing the balls and the second hole goes out. It's a mystery but it cant be too sophisticated
Maybe the firing rate is consistent, but the barrel is oscillating (bending/whipping) fast enough to cluster the impact points. I would certainly expect greater horizontal oscillation due to the acceleration imparted by pneumatic panning mechanism used to move the gun from right to left. Perhaps it is possible to to plot the audio wave form of a series of shots to better understand the variation in firing rate. Audacity is a free app that can plot the wave form of audio files.
The Metal Storm system is well over 20 years old at this point. Some Etymology would not consider airguns true guns because the high-pressure (energy for the system) is external and generated BEFORE the device activates so they are in fact throwers like crossbows and catapults. Cool vid.
dayam that was fun, and i love the way you used calculations as a work-around to not having a high speed cam. it's another topic, but although 890fps is not super-high or very penetrating, at that firing rate the energy is enough to dismiss anything that walk crawls or flies with extreme prejudice, and even the best body armor would have a hard time handling that kind of energy
I tought there was "no full-auto" in the buildings!😂 Holy crap that is just insane... I need this for the next airsoft match and i build me a machine gun nest😂
Pressurized ammunition feed should help make it more consistent maybe. I think the rpm is going through the the ammunition faster than the rate it falls back into the chamber at, (assuming this is gravity fed) somehow pressuring the ammunition to feed (mechanically or pneumatically) could definitely benefit. A random idea I came up with it is gathering a flexible see through tube that is approximately the diameter of the ammunition so it can be stacked in single file line with something that will pressurize the ammunition to feed at the other end. Maybe it can be round bent to make a radiator type configuration to prevent having a gigantic pipe sticking out of the gun. Best of luck on your endeavors!
someone call the slow mo guys or Dustin at smarter every day! id love to see that with a high speed camera. also id love to see the action design. Great work sir. Thank you for sharing.
Brilliant concept, great video. Have you any data on distance and terminal velocity? Would be interesting to see as there are a number of applications for its use.
7:37 My theory on the inconsistent shots are the feeding mechanism. I think the airgun is firing faster then it can feed, those missed shots in between the groups are shots that probably fired but the airgun just didn't have the bb there to fire. Is the feeding mechanism spring loaded? The shots are so fast that the spring doesn't have time to react. I would put money on the loading mechanism as the problem
the bursts/grouping will be from cylinders harmonising due to everything being on a 2ft soft lines back to a manifold, in its current config its probably firing closest to the valve and then ripple out/along, those 2ft feeds are hurting it as being the same length they alow it to harmonise and fire in the pattern your seeing
This is super cool. Can’t imagine going to all this time, cost, and trouble, and not buying a Chronos high speed. I’m sure a phantom is too much but a chronos is affordable if you’re doing this.
I suspect something with the Hornady BB, something very slight or possibly dirty between one or the other??? Something in the anodized BB coating, something microscopic. ............. just guessing.. Or the air disturbituration system ... a pattern is not random, so the BB thing might not be so. I would be interested in knowing what you have come up with as the cause of delay...Please respond.
7:43 I'm guessing that you use spring to push your mag lip in pressurized magazine, or just put pressure behind the BB tube/magazine. in latter case you may have more than one BB inside your barrel, accelerate at different speed tho
Great demo. Not from a multi million dollar lab, but from a garage. Your first .gov contract should be in the horizon. Don't forget to recycle your cans. Thank you for using Coca Cola (KO shareholder). Cheers mate!
Awesome concept, it got me thinking though was the purpose of metal storm to be the fastest firing gun or did it have a military purpose. Turns out if was supposed to be mounted to tanks to shoot down anti-tank missles before they arrived much like c-ram or c-wiz systems, I think an interesting challenge would be trying to build an air gun that delivers the necessary energy at a range to destroy anti-armor missles, but still fires faster than the metal storm.

It absolutely would fuck up a quad, I have hunted a ton of small game with .177 air guns with great results. Make this a .30 cal airgun and the pellets would carry significant energy for a good distance as well. @@IVAN_ENT
@rockets4kids it does tbh haha
Holy crap man, this design is awesome. I'd like a 6 barrel arrangement on a permanent turret with dedicated generator and air supply for starling control 😁
Two seconds and there wouldn't be a starling in a 2 mile radius
I just want a 4 barrel mounted on a swivel chair on the back of a UTV/go-kart
So BB CIWS?
This is the way.
Don't forget to ask for a higher caliber. LOL!
Have you considered that your firing rate might not be that uneven, but that your barrel might be vibrating at some harmonic frequency? That would explain the vertical spread as well as the horizontal grouping.
Interesting thought. Another resonance possibility; eyeball math suggests that there will be between 2-4 BB's in the barrel at any given time and if they are interacting with each other they might be creating a periodic variation in muzzle velocity. (Easy way to check that would be to have two sheets of target 6-8 feet apart and check if the groupings are different at different distances from the muzzle.)
That's possible.
Someone else also mentioned that it could be alternate rotation of the bb's spinning as they go down the barrel causing them to curve in different directions.
Or it could be a pulse forming in the air supply/ammo feed from back pressure caused by rounds not exiting the barrel quickly enough. A bit of tuning with air pressure and barrel length might help?
Without a timing mechanism for the bb's you have created a bb blaster(sand blaster).
@@enduranceG51 I was thinking the same, it's basically a big sandblaster.
That is by far the coolest thing I've been a witness to in a long while. To see all the cans exploding while the final can is being hit and the first can is still in the process of exploding so crazy so cool
You're one smart cookie and one hell of an engineer! Well done!
WOW; great job, this is a really cool bunch of work!
A few years ago I rigged up an Umarex EBOS BB machine gun with an adapter and charged it with 800 PSI from a standard remote HPA paintball tank. It does 8 shot bursts pretty fast at 540 fps.
Yes of course it has a laser sight and it tears through both sides of an empty aluminum cans from 50 feet.
(if anyone wants to go this route; remember to keep the gun oiled or it will malfunction)
Also bottle with bbs + air
Bro don't beat yourself up. You did a phenomenal job. Very impressive I already know you are going to figure out what is going on with the small Gap in fire. Can't wait to see the final results
This is a fair ground side show gun. We used to shoot them at the Royal Show in Adelaide. Was called "shoot out the star" a red star on a piece of paper. If you got the whole star you got another turn.
Super cool. I work for a recycling facility that has 2 optical sorters. One uses 160 MAC Valve, 80 up firing and 80 down firing. The other machine has 64 up and 64 down firing valves. They operate so extremely fast that the human eye cant catch them firing, you have to use super slow motion to dial in the timing of material being fired on. The conveyor speed is around 1000 fpm.
Saving the full speed clips till
The end was a ducking rad choice. Very cool.
Try using an ultrasonic transducer attached to the ammo feeder. This might stop the ”clumping” by giving a smoother feed into the barrel
An ultrasonic transducer isn't the right tool for the job. You need something that outputs a bit more power at a lower frequency, like an industrial vibrator made for compacting sand/concrete, or a slightly less industrial smaller version.
This is beyond overkill. I love it.
great video and project. we studied droplet streams in college and would pluck a droplet out of a closely spaced stream to measure the change in drag and effects from the missing droplet. if you were at a greater range I would suggest that stagger could be aerodynamic vs firing rate. nice work. or an oscillation in the relatively thin barrel?
Thanks for showing where to skip to just see it.
I'd I ever see so much as a reference to this project, I will be clicking into it. This is radical, thanks for making cool stuff
Bro, I was literally just wondering about something like this. You definitely exceeded what I imagined possible. Amazing job, my man!
And we were ecstatic to get 3600rpm out of our airsoft M4s... we were only doing about 280fps with .20 gr bbs... I salute you sir!
That was awesome man, incredible work 🙌
I didn’t think you were going to show the full speed, glad you did! Impressive job
Something that would be super interesting to try given the mechanical and inconvenient limitations of physical movement could be to put a high voltage on the barrel so that the BBs get electrically charged - can then be slightly deflected by electrodes outside the barrel. This would allow near-instantaneous control along two axes. It might additionally offer interesting diagnostic data by hooking it up to an oscilloscope. The amount of current draw should be indicative of the firing rate
He probably used a phone camera for the fire rate measurement which leads me to the assumption that what you are suggesting is outside the scope of the project.
@@glandhound haha your logic appears sound, sir
You just reinvented old Videojet ink jet printer technology with BB's instead of tiny ink droplets. There's a lot of Volts involved!
@@บัวสีโรเจอร์-ศ9ฝyes, it might be good to get @styropro to collaborate 😁
It may not be the firing rate causing clusters. It may be the sweep motion system which is pneumatic. You have an intertial load when the air cylinder first begins to extend. You hit peak pressure here in the pneumatic system. After that you get a pressure oscillation similar to water hammer in a plumbing situation. Water does not compress, but the pipes flex which causes an oscillation similar to a pneumatic system. If you switch to a hydraulic motion system, and use short tubing, you will see the cluster effects diminish. A cheaper way would be to increase your air cylinder diameter and observe the difference.
wow!, someone get this man a highspeed rig for a weekend so we can see that beauty in high FPS. just outstanding work brother.
Brilliant. Really clever stuff and very interesting to watch. Thanks for your originality and all your work.
This was well done. I am a gun nut. And a math nerd I loved it. You gained a follow. I’m glad you popped up
Dude -this is an insane, nasty weapon. I'm not sure where it could be applied, but that's beside the point. Just wow...
Home protection seems like a perfect use. Get off my lawn hippies!
Close-in Russkij drones???
The algorithm provides
absolutely wild, I'm glad to see this
The shot grouping looks like a barrel oscillation, potentially from the actuator or the firing impulses? Or both.
It could be a dynamic funneling of the rounds, A real Slow Mo of the rounds flying will tell.
Really interesting and fun! Glad you finally got around to showing the real-time footage at the end. Thanks for a great video!
whoaaaa dude this ought to blow up. I am a fan of yours now.
I knew where this video was going when he showed the competition to beat design. Awesome idea, i love it. Simple yet highly effective design. You should get in the world record book lol. It would be neat to compare to say a 22 air pellet/ slug in the same design. I know the 22 would probably be slower but can you imagine the ft lbs dropping power of such a thing? I would love to see other caliber exploration with this same design just to compare speed, power and maybe even groupings. This is awesome keep it up.
Well even in current form its already more then enough to stop (or even tear a hole) through person. With that amount of BB`s (that are not even close to bullet in power) it is same as being hit by a truck if spread evenly or with big hole somewhere if they hit one spot.
@@alexturnbackthearmy1907
lt's borderline. It would kill a rabbit but not sure what it would do to a human. Probably leave a messy hole. 9ftlbs isn't much. 60 is sort of minimum to incapacitate a person according to US mil handbooks.
It seems like this would be great for defeating low cost UAV/drones close in, while being cost-effective, might need to scale up the bb/barrels/air reservoir, but seems very doable
We already have it, the Phalanx , ROF is only 4,500 rounds per minute, but with 20 mm Vulcan rounds , more than enough.
Key word being low cost. Those phalanx bullets are not cheap.
@@jaredriddle8320ditto. Usable & supportable is key for war. Watching Ukraine should educate everyone on all wars effectively becoming sieges.
@@jaredriddle8320the effective range of this to actually kill a target is probably measured in feet, not kilometers like is needed for air defense.
@@Chroniclerope maybe. But it would be interesting to see what kind of damage this does to targets other than soda cans, and also if ball bearings at higher air pressures could be used.
would love to see the internal mechanism.. Feeding the BBs to the chamber at that rate is difficult.
What would be really cool would be to see the insides working in slow motion to see what's causing the bursts. Does anyone know if the CCDs in high speed cameras are sensitive to x-rays? This seems like something @AppliedScience might be interested in figuring out.
I can tell you already the bursts are from pressure variances and or turbulence.
It could be binding of the bbs.
@@benjaminshropshire2900 the X-Ray source you'd need to use to use to film that is only available at National Labs. You need a particle accelerator to get an x-ray source that bright.
@@RBMK-ym4dm A few quick searches suggest there are man portable, commercially available X-ray units that are powerful enough that they can inspect large steel weldments in a reasonable amount of time. IIRC those systems are *well* into the "don't stick any part of yourself in there that you would mind falling off" power levels an you can get full motion video at exposures below that used for normal medical x-rays. I'd totally believe that you could end up with rather grainy results, but I'd have to call [citation required] on saying you would need national labs level sources to get anything.
I suspect some sort of x-ray strobe source synced to the CCD would end up being part of the operation. You might not get high frame rates from that, but even lower rate very short exposures could be very useful in seeing what's happening.
Love all things air driven.
Great video
Second comment, I love how monotone you are during voice over but during actual testing I hope you are having a freaking blast!!
This is ART !

Hopefully some helpful advice. To help with gaps in grouping, round ammo is not ideal unless you can create a spin on the BB. I'm looking forward to watching more as this is my first video of yours I've seen.
The guy built this gun 20+ years ago. .
this is insane! those BBs from Hornady, those are no joke. there are a few other black coated ones out there, but these are as serious as their rifle rounds. I liked these so much for my two BB pistols, I ordered several thousand lol. I can shoot weeds in half at 50 feet with these out of my Umarex revolver replica pistol. ultra consistent, most other BBs are not and tend to fall out of the rotary magazines and jam.
Maybe shooting burst wave is created by a harmonic wave within flexi-air hose so remedy would be adding some vibration dumpers to the hose or change hose to more rigit one. Nice project, btw. I'm not a fan of instant death weapons but this one sticks out with simplicity and cost.
Absolutely fascinating...what a great demo.
I have some questions, primarily regarding velocity and dispersion. Since securing single shot data through a chrono will be very difficult, and since it takes time for the pressure to fully build up, do you have any ideas for providing velocity data? I also notice that the scattering on the short range paper target is quite significant. Do you plan on providing dispersion data and approximately the size of the dispersion cone? I'm also wondering how consistent the rate of fire truly is and what causes the variations in the ROF.
Amazing! Clean design. I'd love to for you to break down your feeding mechanism! I feel like that's where the improvements need to be made.
scrolling through the comments to see if anyone mentioned it. I agree. It was not mentioned from what I heard. he couldn't possibly be using gravity...(?) with all the air, there must be a charged feed. ...electromagnetic? super bitchin. great stuff.
there's no second hose or container full of steel BB's.
He may be feeding it through the air hose somehow. Maybe the "magazine" itself is pressurized. One hole keeps supplying the air while pushing the balls and the second hole goes out. It's a mystery but it cant be too sophisticated
Maybe the firing rate is consistent, but the barrel is oscillating (bending/whipping) fast enough to cluster the impact points. I would certainly expect greater horizontal oscillation due to the acceleration imparted by pneumatic panning mechanism used to move the gun from right to left.
Perhaps it is possible to to plot the audio wave form of a series of shots to better understand the variation in firing rate. Audacity is a free app that can plot the wave form of audio files.
Duuuuude, very epic, dont understand how you managed to do what i just saw. Legendary brother.
The Metal Storm system is well over 20 years old at this point. Some Etymology would not consider airguns true guns because the high-pressure (energy for the system) is external and generated BEFORE the device activates so they are in fact throwers like crossbows and catapults. Cool vid.
This is incredible!
Have you tried not moving the gun and hitting roughly the same spot on a piece of steel for x amount of time or shots?
Somebody needs to send this to The Slow Mo Guys !!! !!! !!! !!! !!! !!! !!! !!! !!! !!! !!! !!! !!! !!! !!! !!! !!! !!! !!! !!! !!!
Or ballistic highspeed.
Gotta love a man who knows how to 'crank the numbers'.... fellow math and physics geek. You sir have a bright future...
This got my sub. Id love to see this evolve
This is absolutely ASTONISHING!
dayam that was fun, and i love the way you used calculations as a work-around to not having a high speed cam. it's another topic, but although 890fps is not super-high or very penetrating, at that firing rate the energy is enough to dismiss anything that walk crawls or flies with extreme prejudice, and even the best body armor would have a hard time handling that kind of energy
Incredibly smart man !!!
I tought there was "no full-auto" in the buildings!😂 Holy crap that is just insane... I need this for the next airsoft match and i build me a machine gun nest😂
BRO!!!!! YOUR BRAIN IS WORKING AT FULL COMPASITY!!! THIS GUN IS AMAZING BUT ALL YOUR MATHING WAS MORE INCREDIBLE THAN THE GUN!!! 😮😮😮😮😮😮😮😮😮
Pressurized ammunition feed should help make it more consistent maybe. I think the rpm is going through the the ammunition faster than the rate it falls back into the chamber at, (assuming this is gravity fed) somehow pressuring the ammunition to feed (mechanically or pneumatically) could definitely benefit. A random idea I came up with it is gathering a flexible see through tube that is approximately the diameter of the ammunition so it can be stacked in single file line with something that will pressurize the ammunition to feed at the other end. Maybe it can be round bent to make a radiator type configuration to prevent having a gigantic pipe sticking out of the gun. Best of luck on your endeavors!
someone call the slow mo guys or Dustin at smarter every day! id love to see that with a high speed camera. also id love to see the action design. Great work sir. Thank you for sharing.
You are doing the Lord's work. Keep it up.
Like the ingenuity with the limited Equipment.
Maybe the clusters at 7:50 are related to barrel oscillations due to the fast sideways movement?
Brilliant concept, great video.
Have you any data on distance and terminal velocity? Would be interesting to see as there are a number of applications for its use.
That is by far the best thing I have seen today
7:37 My theory on the inconsistent shots are the feeding mechanism. I think the airgun is firing faster then it can feed, those missed shots in between the groups are shots that probably fired but the airgun just didn't have the bb there to fire. Is the feeding mechanism spring loaded? The shots are so fast that the spring doesn't have time to react. I would put money on the loading mechanism as the problem
Hey dude, great Video and a very good idea. A fantastic Experiment. Bring it to a Company who creates Airguns.
the bursts/grouping will be from cylinders harmonising due to everything being on a 2ft soft lines back to a manifold,
in its current config its probably firing closest to the valve and then ripple out/along, those 2ft feeds are hurting it as being the same length they alow it to harmonise and fire in the pattern your seeing
It is amazing how you managed to make this video like this without using high speed cameras
Metal storm! What a classic YT video
Your calculations are impressive...
Would love to capture this beauty in ultra-high speed video! See what it does to some interesting targets.
fps can be counted with a laser or infrared sensor, much more accurate then video method.
*No full auto in the buildin-*
This gun: *Brrttzz*
I've waited years for this
Very interesting. Good job putting this together 👍🏻
I think it's safe to say sir, those cans that survived won't be bothering anybody again anytime soon.
Id love to hang out with this guy. The cool stuff he can develop would be awesome
You may find the gaps are due to barrel wobble rather than rpm changes. Great video.
This is super cool. Can’t imagine going to all this time, cost, and trouble, and not buying a Chronos high speed. I’m sure a phantom is too much but a chronos is affordable if you’re doing this.
I was about to lose my mind at the thought that you weren't going to show the coke cans in real time. Clutched it at the end though
I suspect something with the Hornady BB, something very slight or possibly dirty between one or the other??? Something in the anodized BB coating, something microscopic. ............. just guessing.. Or the air disturbituration system ... a pattern is not random, so the BB thing might not be so. I would be interested in knowing what you have come up with as the cause of delay...Please respond.
7:43 I'm guessing that you use spring to push your mag lip in pressurized magazine, or just put pressure behind the BB tube/magazine. in latter case you may have more than one BB inside your barrel, accelerate at different speed tho
would love to see more of this tho
Sheriff: Now men, take 10 paces, turn and fire!

Cheers mate!
There is NOTHING to be disappointed about regarding those results my guy.
Well, that gets my sub. Nice work man. Very interesting.
Awesome concept, it got me thinking though was the purpose of metal storm to be the fastest firing gun or did it have a military purpose. Turns out if was supposed to be mounted to tanks to shoot down anti-tank missles before they arrived much like c-ram or c-wiz systems, I think an interesting challenge would be trying to build an air gun that delivers the necessary energy at a range to destroy anti-armor missles, but still fires faster than the metal storm.
absolutely genius engineering. congratulations my friend.
Ain't much but it's honest work, and triple the claims of the other guys. Also just on level of a hobby enthusiast for precision machining, scientific documentation, and fun, because I like doing what I like. I sound to casual at times, but I really do know how to have a good time.
