BB Machine Gun(NOT AIRSOFT!!!!!)

This BB machine gun is powered by an air compressor and can shoot about 500 BB's in a couple of min. Fairly accurate and has a range of about 200 feet!!! Slices, dices, and rips em' new ones!

Step 1: The parts

First off, this is not an easy build, it takes patience and craftsmanship to get it all together.

The parts I used on this gun are pvc pipes (rated at least 400 PSI!)Including the pvc drain trap and all reducers/splicers.

All of the brass fittings need to be npt(national pipe thread)I used 3/4".

As for the stock and the barrel, the came off an old pump action bb gun, but those were just to make it cooler.

The trigger is a blow gun, and the laser sight is optional.

The most important part of this is the VORTEC BLOCK, which itself takes some time to make.

Comments

[Dr.Bill]

Well there's a lot of things that are different between our countries. You should come to Rye, NY and visit a place called "Play Land". Inside Play Land you can find a little booth to shoot co2 powered BB Guns that are machine guns but they are Co2 powered. A gas powered machine. No flaming powder. They are classified as AIR GUNS and as such do not use Fire. They shoot. However if you are talking expressely in terms of Silencers being Legal For Guns, the answer is No. Originally I thought there was discussion as to weather or not this BB Gun was a fire arm. Clearly it is not. It uses compressed to a tank gas to shoot. At any rate it looks like a fun Toy. You should not use a silencer with it. Rats will never know what hit them. Bye!

[Ranie-K]

My personal understanding is that you legally CAN suppress it in the US as long as the suppressing part is not removable.

[freddysserpent]

Dude if you want a silencer in the U.S. You can apply to the BATF for licencing. Its pretty much the same requirements as for manufacture of firearms.Or so I found while I was there. You can do the same thing here in Australia except the requirements are stricter. Also Australians beware airsoft and air/co2 powered weapons are legally classified as firearms so if you want to use this stuff please be on the lookout for the johnnies

[mr.pizza]

im 13 i under stand all the cocepts and engineering of the design but due to my age some parts are hard to come by could i substitute some of the parts and maybe funnel the entrance for the bbs in the vortex to reduce jamming?

Which is mentioned in step 2.

Click on the hyperlink "vortex block".

[TSC]

Nice 5stars!!!!!!!!!!!!!!!

[Ianman]

Thanks!

[TSC]

Your welcome!

[Aron313]

Make a video. Some guns that i made with plans offline didnt fire far or ran out quickly

[Ianman]

There is a video right under the main pic and description.

[Aron313]

ok thanks

[Billy mahony]

What did u use for your vortex block?

[Ianman]

Bondo, read the inst.

[Billy mahony]

it looks like a solid chunk of copper or bronze.

[Ianman]

Copper BB's will discolor it.

[skidoo]

Neat project and all, I guess. But 500 RPM? That's only like 8 shots a second. And what sort of muzzle velocity are we talking? I dunno, 24+ rounds-per-second (1440 RPM) is nothing for a decent airsoft gun shooting .25 gram BBs, and I don't see why you couldn't push steel BBs at the same rate. Especially if you're using an air compressor and a vortex block. More thorough instructions would be nice, so we could more precisely suggest how to improve your rate of of fire. "A" for effort though! :-)

[Ianman]

8 Shots a second sounds like to much?
Watch the video. And listen...

[guitarmonk15]

would a gravity fed magazine work instead of the vortex block? I'm thinking about a pen tube filled with bbs.

[Ianman]

It is already gravity fed...

[adrian09]

do u hav a video of the whole process? or more detailed ones..

[Ianman]

Nope, going to have to use your imagination.

[Billy mahony]

Does anyone have any ideas on running this off a CO2 tank, Making it more portable.I have no idea on how to regulate the flow? pressure, any help would be great.

[Ianman]

No, you need a high CFPS rate that only a big air compressor tank can accommodate.

[guitarmonk15]

Do you mean running it on something like a co2 bike tire inflator? Because I had that EXACT same idea. I'm guessing it would work pretty well, but I have never tried it.

[Billy mahony]

I was thinking something slightly larger (Paintball tank) but yeah, annything light and portable, how fast do you think the flow is on a tire inflator, my guess is pretty low, but it should work.

[dla888]

Get a CO2 regulator. Look on amazon, or ebay.

[prop master]

could you modify this for airsoft

[Ianman]

As long as the barrel was the correct internal diameter, but why wuss the gun up like that?

[rocketman217]

Hi, could i power this with 8 gram co2 catridges?

[Ianman]

No.

[besty1262535]

were is the other part

[Ianman]

Did you mean *where is the other part*?
What other part?

[Football viking boy]

those pipes 400 psi ? WOW those must be bought online

[coilsinamotor]

wow very clear drawing of the block 5/5

[Ianman]

Thanks, But not my doing.

[six shot]

hey, if you put a wooden/cardboard/plexiglass body on that, you could make the wunderwaffe dg-2 from nazi zombies.

[Nandthemountingplusman]

I remember using the ordinary and old style of airgun for bird hunting when i was young. I think i can enjoy more now by availing the benefits of technological developments. Is it possible to put a scope in my airgun like what i have seen that are connected to riffles such as the AR 15 Scopes? Are these kinds of rifflec accessories adaptable to airguns?

[prodo123]

You're gonna go bird hunting with a fully-automatic machine BB gun with an Colt AR-15 scope? You're gonna explode the poor pigeon's brain

[cyborgpigeon]

that thing is NICE! ive been wanting to try something like that for a while. I think ill try to run mine off fridge pumps and rechargable cylinders when i get around to it. i know 1 liter at @ 500 psi won't run a full auto bb gun for long but thats what im gonna try. only down side is i live really close to the local gestapo headquarters. im from the u.s. these things are legal but they are frowned at by the sheepel patrol. and no something that is compressed gas powered is not a fire arm! i feel that laws that say that are tyranical bs. if you want to see something similarly Evil!? go to spudfiles dot com and do a search for "DeathRay". just look through their site first before you start askin stupid questions. they have lots of info on how to make airguns. remember no one likes to spoon feed lazy people.

[imthatguy1125]

 those fridge pumps take forever to pump u a co2 cylinder to 500 psi ive heard , to slow of flow

[cyborgpigeon]

yes the small ones can be slow and tend to tap out at 275- 350 psi. example mini fridge compressor. but the big ones can be scary fast and dangerous. example full size fridge compressor or window air conditioner compressor.
do not ever attempt to use one unless you know what you are doing! its highly dangerous and not for beginners. they can output lethal pressures i cant stress that enough!  also the case around the pump is subjected to the overall system pressure. the cases can separate with potentially lethal results. there was actually a law suit where one came apart during a test at lower than the supposed rating. there has been at least one person crazy enough to do a max test on one. his was able to reach pressures in excess of 1000psi, needless to say that is an extremely dangerous thing to do. a long time ago i had one hit 750 plus psi in seconds. that was way too close to death for me. not a thing to be taken lightly in the least.

[Gksarmy]

so...if one were to set several of these up together in a series with spring caps calculated to release when the pressure was around 700 in each tank/compressor...death?

[~Aeronous~]

damn it! the stupid web filter at my school actually works

[Sundevils2234]

To add a safety, just add a small valve in between the blow-gun and the vortex block.

[Ianman]

Thanks for the input.

[NEALP123]

can you ues a bicyle pump insteat of psi

[max0506]

why do you need a vortex block why don't you just have a tube with BB's in it a hole for the barrel and a hole for the airinput.

and do you need a pressure reducer so the air streems out slow or can you just place a ball valve and open the valve so the BB's slow the air down
(I use a pressure champer not a compressor or somthing its portable)

thax and a nice gun!

[imthatguy1125]

 umm are you talking about a cloud chamber

[Ianman]

Physics, you dont understand them. Therefore, please do not attempt to build any weapon or projectile launcher.

[max0506]

don't be angry!!

and I already made a airgun for marbles or that kind of projectiles.

[siggi]

can u make better blue prinnts so we can build are own gun thats as cool as this one. plz

[covey12]

i made a vortex-cap instead of a vortex block and mine shoots 60 bbs a second, and to much money to shoot it for a whole minute lol thats like a couple thousand bbs

[~Aeronous~]

how/

[~Aeronous~]

oh hey can you plz upload an instructable for this one and an instructable for the vortex block to? im stuck on this and Im not sure what to do.

[andrebododea]

How much compressed air would u need to power this thing? Like you buy those cans of CO2, but how much would u need to attach at once? And you attach it to the end of the blowgun right?

[~Aeronous~]

no. i just used some compressed air in a can. they cost about $5 but i modded mine so i pump it up again every 200 shots or so, and i attach it to the end of the barrel

[siggi]

how does he load that thing.

[~Aeronous~]

easy. unscrew the lid and pour the bbs in

[dmantha]

I wish to verify the legal definition of firearm for any that are wondering. The exact US Legal definition of Firearm by title 18,part I, CH 44, SEC 921 says:

(3) The term “firearm” means
(A) any weapon (including a starter gun) which will or is designed to or may readily be converted to expel a projectile by the action of an explosive;
(B) the frame or receiver of any such weapon;
(C) any firearm muffler or firearm silencer; or
(D) any destructive device. Such term does not include an antique firearm.

I got this definition from the database of cornell university law school at this web address:
http://www.law.cornell.edu/uscode/18/usc_sec_18_00000921----000-.html

This is the legal term for firearm. Because a air gun does not use an explosive, it does not fall under the term "firearm" by US federal standards. I do not mean to step on anybodies toes. I personally wanted a legal definition of firearm and thought I would share what I found.

[~Aeronous~]

is this techically legal?

[dmantha]

If you mean "technically", then yes....as far as the laws about firearms are concerned. If there is any legal problems, it would be with a different law that would be over items other than firearms. Examples would be lethal weapons, alternative weapons, compressed gas weapons, or something of that nature. If a law only refers to "firearms" then it does not cover airguns since airguns launch projectiles through NON-EXPLOSIVE means and by federal definition firearms specifically use EXPLOSIVE means.

[l3owzaaaah]

I want one, but where I am the pvc sizes are on a different system and I don't know metric to inches translation. Interested in a contract? Same build is fine but could the trigger be nearer the handle rather than the stock and give me an approximated price for one of that's okay. I have a compressor so it should be okay.

[spman123]

I'm guessing there won't be any updates on construction :(

[Dr.Bill]

We do make the distinction in the US as to what a fire arm is. A fire arm uses gunpowder. Muzzle velocities start some where around 900 fps. The last pop gun I used that was that slow was a 22 cal cb short for killin rabbits for the freezer. My first BB gun was a crossman 760 and it would shoot a pellet at 900 fps. The difference is in USA a fire arm uses gun powder. Don't even think of even making a silencer for your BB Gun. The ATF will take it and you if they find you with one for any kind of gun mainly because it can be used on a real firearm also if it is made out of plastic it could be deemed a terrorist tool. Good Bye And Good Rat Hunting.......

[knoxarama]

that is a firearm. A siencer is illegal to use with this. Anything that fires something is a firearm.

[Dr.Bill]

seems an awful lot like an air gun. no powder, no fire.

[knoxarama]

no, air guns are firearm. and they do fire. i think your thinking of the plasma fire, where is fire in this case is to launch as a projectile.

[masterofsniping92]

I agree with knoxorama to a degree. Legally speaking, airguns are considered firearms if their velocity exeeds 500 fps(at least in Canada). So, this COULD be a firearm if it had a velocity in excess of 500 fps. In that case, it would be illegal to put a supressor on it, as stated in my comment below. However, There is an exception. If you purchase an airgun with a suppressor already installed, such as the Gamo Whisper, it is 100% legal to use, so long as you dont take the suppressor off and make your own. Consult the BATFE for more information.

[Ianman]

And what the heck is a siencer?

[knoxarama]

a silencer muffles the noise given off by the gun. It'sbasicly a little tube with some stuff in it.

[masterofsniping92]

The correct term is actually "suppressor", since it only suppresses the noise, rather than completely silencing the weapon.

[Ianman]

Spell check, make friends with it.

[knoxarama]

really, i just don't trust their spell check. it has nothing. i put in nuclear, just as i spelt it there, and it gave me neuron.

[Dr.Bill]

The gun does not fire. It shoots. To say that it fires implies that it uses a propellant that is combustable. You have an AirGun.

[knoxarama]

if it uses air to fire it, it is AIR SOFT!

[Dr.Bill]

AirSoft is AirSoft This is just another AirGun

[awaite]

Hey can you only use this with the air compressor attached or is it portable?

[Dr.Bill]

CO2 expands 750 times its own volume out of an extinguisher. A 45 lb fire extinguisher will supply enough. You can even wear one on your back with a scuba pack.

[Ianman]

Did you read anything on here?

[legokevin360]

funny pic

[Dr.Bill]

Power Ball Machine On Crack! Good Laugh!

[gunsnroses]

hey nice gun but just one question: why is the trigger on the stock? wouldnt it be easier to fire from the shoulder if you put it on that 45 degree black tube further forward? again very nice gun and kudos to you

[logann2292]

This interesting. I am currently doing a project, and this is alot of help. I'm trying to use this same idea, but have a revolving quad barrell system. I think I am going to try to use one air compressor, and 4 vortex blocks, as I have a big air compressor, but I'm not sure if its possible with the vortex block being upside down at some point, and the big pvc drain tap. Any ideas anyone? Thanks.

[Ianman]

Im a bit confused. You are going to use a revolving set of four barrels and four v-blocks? if the barrel is revolving, how are you going to time the line up of each barrel to a v-block and the bbs not jam up? With the steady psi needed, you wont be able to controll when the bbs come out. As for the v-block, its doesnt have to be any specific shape, as long as there is an inlet, outlet, and a way for the bbs to enter the vortex. Before I built my 1st v-block, I made a mock one to demonstrate the theory. I used a scrap piece of a 2x4, drilled a 1 inch hole appx 1 inch deep with a forester bit ( so the hole was flat on bottom) and drilled the inlet and outlet holes in tangent and at right angles to each other. Then I put 5-8 bbs in the hole, clamped a piece of plexi over the hole and stuck a blowgun in the inlet hole. What you will see is the bbs spinning around the inside diameter of the 1 inch hole (hence the "vortex") and as soon as a bb lines up with the outlet hole, it escapes at a velocity corresponding with the psi applied and the snugness of the outlet hole and the bb coming out. I reccomend testing this outside of course and at a low pressure. This should give you a really good idea of the internal physical dynamics in progress with out the big build. Hope this helps, let me know. Thanks for the question.

[logann2292]

Actually, what I think I'm going to try to do is drop the revolving barel idea. I'm going to made the vortex a little bigger, and drill 4 holes for 4 barrels into the vortex. I have a powerful air compressor, so it should be fine. You think this will work?

[Ianman]

Glad you are dropping the revolving barel idea, though it would look fricken awesome. As for the 4 holes in the vortex block, It might work, but you will be losing a lot of air and pressure. Think of it this way... In the split second that a bb enters the outlet, it causes the internal pressure to build a bit (resistance), thus producing more force propelling the bb. With 4 holes, even if 3 bbs are expelled at the same instant; the 4th one is just spewing air and reducing the power behind the other 3. Sorry to sound like a bummer on your ideas, it would make an awesome gun, but it would take alot of very precise engineering and tight tolerences to make it work perfectly. Even with my single barrel, it can jam, the v-block wears out, and the bbs in the vortex are extremly chaotic and impossible to predict when they will come out. Im blabbin, so ill stop.

[Billy mahony]

is the stock from an old pumpmaster 760,(by Daisy)?

[Vertigo666]

does it fire at a constant speed? like do the bullets come out at regular intervals?

[Ianman]

Fairly constant, probably around 10-15 per second. Sounds like a quiet machine gun, though it does jam on occasion, but a quick shake clears it up. Ill try to add a video

[irwinner]

10-15 a sec is nothing i made one of these that shoots 50 - 100 a sec, was just using it i an airsoft game yesterday and it didn't jam once. the problem with yours is you don't have a shroud on your vortex block, if you don't have one it slow the rate of fire and makes it jam easier and those pieces are definitely not rated to 400psi, if you believe that you obviously haven't done much research, for example the tee your using as a bb chamber is NSF-DWV, as in drainage pipe. its only certified to 60psi (although i have pushed one to 115psi with out failure a few time). the clean out and bushing your using are also DWV. and you don't need an air compressor to use one of these all you need it a 5 gallon air tank, or a regulated co2 setup so you can make it portable pretty easy

[Billy mahony]

could u explain the CO2 setup, with pics plz.

[Ianman]

It does not use Co2, it uses compressed air.

[Billy mahony]

i was commenting irwinner, sorry for the confusion.

[bigal77]

What psi do you have your compresser at

[Ianman]

rwinner, thanks for your comment. First off I did put the shroud on the vortex block, Its lying next to it in the pic for clairity. Other than that all of the PVC I used ARE stamped with the psi rating, and I guess your just better than me!

[knexer1]

Thats true, all of the schedule 40 pvc pipe that I have seen is rated to at least 400 psi.

[Ianman]

Also an air compressor IS nessary because any air tank is a major pain if you have to drive down the gas station to fill your tank with air every 2 min worth of shooting. And remember folks, If there is a constant airflow through any chamber, it will only reach less than half of the PSI applied unless you stick your finger in the end of the barrel and apply pressure.

[irwinner]

ill admit the 5 gallon tank is a pain in the a$$ to lug around but the gun is insane, the equivalent to having a Gatling shotgun, sure i can only fire for few min straight but the guns fire rate is worth it. i can get around about 3000 rounds off on one 115psi tank (and still have 40 psi left). and i can refill the tank with a bike pump a 5lb co2 setup is much better you can get 25000 to 30000 rounds off in one tank (regulated to 110psi) the tank and regulator are about 15 lbs and can easily fit in a back pack. i believe i know why your RoF is much lower than mine, it seems you used a 2" chamber, mine is 1.5". so because there is a smaller area to pressurize the pressure increases and the bbs can shoot harder/faster i do have to admit your gun looks ALOT nicer than mine, but you should seriously consider a co2 setup, a gun like this on an airsoft field is unstoppable

[bigal77]

Would u recomend a specific type of regulator?

[Ianman]

Thanks again for the comments and compliments! I do have a question though.... Are metal bb,s allowed on an airSOFT field? If so I could really piss off some people when their kids go to the hospital. HEHEHEHEHEHE ( snide grin; pinky on lip) Because this doesnt shoot those plastic ones.

[irwinner]

sorry but their is no way they would ever let you on an airsoft field with metal bbs, cause they could be held responsible for anything stupid you do, and with the way modern America works they will get sued. the short answer no

[Ianman]

You really understand scarcasm dont you!

[irwinner]

you can check it out on my website

http://home.comcast.net/~irwinner/airsoft.html

[brookech]

Awesome dude. thanks for the info much easier to under stand than burntlatke!!!!!!!!

[Ianman]

Looks just the one from burntlatke.com. but I dont remember the electrical tape on the handel. I got the Idea from the same place too, I just tried to improve upon the asthetics a bit, along with the construction. Thanks again.

[Vertigo666]

hmm... 10-15 p/sec... 10x60...15x60...400/60...NICE! my stock P-90 full auto is 400 p/minute

[bruce911]

Whn will you be done with the construction process?

[Ianman]

Its been done, theres a vid on here too.

[bruce911]

Where do you get the Blowgun trigger handle thingies.

[MisterHankie]

You can buy the blowgun from a hardware store.

[Nitornos]

Jeez, seems like you have to get everything on an instructable from a hardware store.

[Ianman]

If you have to ask, you dont need to build one of these.

[xxaaron1015Xx]

I know how to make a extremely powerful be gun for only $2 i live in nsw (Australia) and there banned so 1 day i got bbs and i was bouncing em they landed in the barrel of 1 of my bros toy guns so tried it and i can fire it with high possibility of hitting. as i set up red bull cans and shoot i can get up to 20m away and still nail em. contact me if you wish 2 know how to make :D

[Ianman]

Good for you, lay off the red bull.

[purpledog22]

dude soooooo cool can u tell me like all the pieces like everything plz????????????

[Kainon03]

i want to build this but i am wondering what exact fittings you used and what type of tubeing and where you got it. thanks

[xxaaron1015Xx]

can u add a detailed instruction on Instructables like how long what pieces glue or what material to make barrel and vortex as my dad is a electrical engineer and owns a business (cnc teknix) I can make the vortex with ease but i need length or the pvc piping add me on msn or just message me on here if u want to add me on msn contact me in email over instructables

[hvac2010]

I'm confused...wuts the point of the vortex block?...couldent you make a more powerful gun by having a strait barrel with the air coming from the back and BBs just falling in a hole in the top of the barrel?

[Ianman]

Without the vortex block, the bb's would just jam up very easily, it keeps them spinning and in line to go out the barrel. Also, if you tried to drop bb's into a pressurized tube "From the top" as you stated they would be blown away and never go into the tube in the first place. Hope this helps.

[maxidk8000]

i still need to know where the brass fittings go can you show me where exactly? i have everything else though

[Ianman]

the only fitting you cant see goes into the base of the V-block, through the bottom of the rounded pvc cap.I used one like this...just get the size you need.

[avwos]

(removed by author or community request)

[Ianman]

No.

[legokevin360]

when i figured this out THIS IS BEST BB GUN EVER all my friends are jelus that i have a bb gun like this!

[MisterHankie]

You know the pipe on the top of the gun with the awesome paint job? Is that just extra space to put more BBs in?

[Ianman]

Nope, its empty. Holds a maglight though.

[MisterHankie]

What sort of mechanism did you use to distribute the air to the barrel and the vortex block?

[Ianman]

That is a blowgun.

[legokevin360]

aculy this is great

[Dr. Explosion]

This is awesome

[bigal77]

What kind of blowgun did u use on your gun?

[Ianman]

Just what home depot had cheap.

[bigal77]

thanks, But what is the barrel length (top "barrel too) and diameter, and if u had the materials and machines could u make the block out of metal (aluminum), one last question, could that blow gun hold up to the pressure of a co2 tank? thanks sorry for being a bother

[legokevin360]

It doesnt work!

[Ianman]

Then you did something wrong, nice comment.

[Wingmaster700]

did you use a hop up and how did you plug the suppoprt barrel to keep air from flowing Sry for so many questions, it's an awsome project

[JamesRPatrick]

I hate when people mistake BB for airsoft. It drives me nuts. Hop up is not necessary with metal projectiles.

[Wingmaster700]

sry, just asking a question. is it against the law

[gotja]

this is a bb gun and adding hop up is basical making a back spin if u do it with a bb gun it will destroy the hop up and bbs are much heavyer than arisoft bbs so it doesnt need hop up cuz it has momentum to mak it go straight (i think there some rifled bb/pellet guns though like a real gun)

[_soapy_]

It's not hop-up, that's airsoft. This is a BB gun.

[Ianman]

I dont know what a hop up is, but the end of the trap where the upper barrel comes out has a thick piece of lexan JB welded and siliconed inside.

[Wingmaster700]

I built one just recently and im wondering if you can attach a paintball tank to it

[denver22299]

dud found out never mind can u post plans

[denver22299]

dud nice but i dont get how the bb go down the barrel wouldnt the air leak out of the barrel

[willstab]

can i try to mini size the the whloe pvc vortex tude and use 1" instead og 2" cuz im planning to make one and make it look like a Dragunuv sniper rifle

[joeliolyijr]

would you be willing to sell the vortexes

[Ianman]

I accept paypal and would need specific dimensions on your application's requirements.

[joeliolyijr]

ok how much would u chart for one

[Ianman]

That depends on your specific dimensions on your application's requirements. In other words, do you need a taylor made block; or something to build a gun around? And if you meant charge, email my account.

[willstab]

want materials can i make this out of, i have alot of wood lying around so i could make it out of that but im worried that the bb's will wear out the vortex (if i use airsoft pellets will it last longer???)

[Ianman]

Read the instructable. Or have someone read it to you. I would do it, but I would still be typing words. So sorry.

[Enzo55]

I´ll make one. But hey, how much psi can it go up to?? And a nother... Lets say that i where to sell a couple of these, what price do you think i could put on them, selling them to people that have never owned an airgun before. And how much does it cost to do this gun??

[hackgeek]

hey if you sell them your braking the law cuz this gun has already been made, and sold at

http://www.pipersprecisionproducts.com/videos.htm

but i doubt your gunnu get cought unless someone rats you out. but im not gunnu

[grenades_and_ham]

so unless they have a copyright or patent on the design its not protected. plus you can make a cloud chamber less pieces and more reliable. because vortex blocks DO WEAR DOWN AND FAIL!!!

[Ianman]

Sorry to sound so bitchy, but THIS gun has not been "already" made, this is my design, the only thing not original to me is the vortex block which I learned from Burntlatke.com.

[Ianman]

If you sell any of these your asking for trouble, as soon as someone gets hurt, you can be sued!!!!!!!!!

[cowscankill]

not if he makes them sign a paper saying he's not liable for damage done to people or property

[clare4668]

i will pay you to make me one, will you make me one and post it to me. I will pay $550 for one plz!

[rownhunt]

make ur own it's easy plus u can get a real rifle for 550 bucks

[thoraxe]

u could get a professional one for less dude.

[Ianman]

Where? Thats what I thought.

[Ianman]

Cash up front. and it may take some time....

[rownhunt]

good iam putting on my fav list cos want to make a barrel smaller so i can shoot bb and pellets thank you

[jdavi303]

hey can u send me the plans when u get them at [e-mail]

[Ianic]

What is the air supply cauze i noticed on your link it had one but urs doesn't. Where does the air come from?

[Ianman]

An air compressor.

[Ianic]

how big is urs? Could u use a c02 cartrige?

[Ianic]

cartridges*

[Ianman]

I have a 15 gal a/c. I doubt you could use the small cartridges for bb guns cause of the lack of constant airflow. Possibly a co2 tank for a paintball gun, but that would get expensive really quick. You could get a air carry tank and refill it at the gas station if you don't have access to a real air compressor though.

[Ianic]

What would be the easiest though? I have tried multiple things and a bike pump just doesn't cut it for an automatic. Also did you spray paint the gun black?

[Ianic]

or maybe even a portable airsource?

[Molybdenum]

you say its a hard build, but you haven't bothered to explain the build process very much. the concept could easily be used for airsoft or any othe caliber (i dont know about paintball) so I dont see why its so important that its not airsoft.

[brainspater]

Dude I got a grate idea that you may like, but you need a long steal tube.

[James (pseudo-geek)]

ahahahaha I'm gonig to build one and put a silencer on it too but could you explain in further detail how to build the vortex chamber?

[steven123654]

well go to burntlatke .com and lanman does this gun work good because i saw like year ago and i was thinking of making it but i never knew if it was any good

[gotja]

dude if you get caught by the cops with the silencer and it works on a real fire arm ull get sued and jailed(dont think thats a word though)

[James (pseudo-geek)]

I looked that law up. its perfectly legal to own a silencer for a firearm, just not to USE it. anyhow this isn't a firearm so its perfectly legal.

[JordanZed]

I doubt a silencer made for a PVC BB gun would work for a real firearm lol

[Hawaii00000]

Dangerous!! and probably illegal. Be carefull where use this as the police can shoot at you just for carrying it around. And again its probably illegal.

[James (pseudo-geek)]

I looked that law up. its perfectly legal to own a silencer for a firearm, just not to USE it. anyhow this isn't a firearm so its perfectly legal.

[gotja]

its perficaly leagle and jordanzed even if it only silences one shot for a real gun (i dought it would work) its still considered a sound supresser or a silencer

[Ianman]

Again....... http://www.burntlatke.com/bb.html

[James (pseudo-geek)]

I looked there, I need more exact details. how wide does the chamber need to be.

[wblac1]

looks like two air lines, can you send a break down of this? thanks,

[Ianman]

Just one airline, from blowgun thru handle and into bottom of vortex chamber. The black thing you see is the wire to the laser sight.

[wblac1]

CHECK THIS OUT.

[steven123654]

yo u stoll this off burtlake.com but they have better intruction

[Ianman]

Steven123654 you are a real genius!!!! I have linked burntlatke.com (not lake) in my instructable as a source, as well as stated thats where I got the idea from and improved the look. And you may want to look for an instructable on spelling words, let me know if you need help with that. LATA

[James (pseudo-geek)]

don't you just love it when people don't read what you write throughly and then complain to you about it?

[mindkiller213]

nice job bro can I get me more detailed steps to making one of this like how to make the vortex block and such?

[sackables]

i went to burnt lake or whatever and i was wondering if they glued the vortex block to the 2" cap or screwed it? If i ask for a 1/4"x1x8"NPT brass fitting or a 1/4 brass compression fitting will they have them?

[yomama1800]

i went to lowes and holy crap they have everything you need i spent 25 dollars and it works great make sure u use plumbers putty it works best and dries faster oh and don't use wood unless u have a 3d drill auger which is rare so yah

[Ianman]

awesome, Send me some pics!!

[_soapy_]

You could ask them. I'm not sure they hinge their lives on your every word here in the same way we do...

[Sergeant Dotson]

Very nice, looks hard to make though...

[nerfer192]

you should make it c02 insted of lugging around an air compressor

[thedude2111]

just dont pressurize or load them and do 1 of those 18 or older only thinggs

[thedude2111]

yo i need 2 get 1 of these they look gangsta and i thought u should make a few and sell em on ebay. ps its legal cause burntlatke doesnt have a copyright

[lewisbirch]

awesome

[HALFSPOOL]

yeah, dude that's pretty sick

[Ianman]

Thanks!!

[gotja]

hmm you can probibly cange it into an airsoft gun realy easly

[DerMaverick]

I built one, took me hours to make my vortex block even, smooth, and have all the holes lined up, yet, my bb's only go about 10 feet with a 90 psi output. My barrel is much bigger than the bb's but i tried with airsoft to the same effect. My design is different because in the 2" 'T' section I mounted it so the vblock was in theshaft andthe top of the block touching the top of the 'T' If any one has any ideas about what's wrong or needs pics send me an email [e-mail]

[Ianman]

First your barrel needs to be just big enough for the bbs to come out, you are losing alot of back pressure there. Also having the v-block so high inside the T, not enough bbs are able to get into the inside of the v-block. Hope this helps.

[Ianman]

PS, even though the airsoft may be closer to the size of the barrel, they are much lighter than metal bbs, so they will just blow around inside the chamber.

[knightlord454]

if you want an upgrade on your design email me my address is [e-mail]

[shooter1]

Where do you load the bb's

[Ianman]

The drain cleanout in the back of the t unscrews

[ghost2human]

is it possible to add something on the inside of the vortex block to have a better shooting rate?? since right now, the air blows up and the BB's follow the curve eventually going in to the barrel right? But if you add something like a V shaped piece guiding the bb"s into the barrel wouldn't that be better. And also how fast does it go . ( in FPS pls)

[Ianman]

I put a shroud around the v-block to help keep the weight of the bbs from jamming inside the block, otherwise i have not had a prob with them not wanting to go out the barrel because the v-block creates a venturi effect taking any matter(bbs) with it. With the other question, i have no idea on the feet per sec. I hope this helps??

[ghost2human]

.......whats a shroud??

[Ianman]

This is a shroud.

[sackables]

how would you hook your air supply to the blowgun if i were to use a 20oz tank of co2 as the source

[Ianman]

I would take the tank to a hardware store and find the fittings to match them up, if you need help, ask someone who works there.

[sackables]

hhmmk

[shooter1]

Good idea i love this gun.

[Mr Tenacious]

do u know if there is any way u could have the vortex block put in a nerf gun or airsoft gun?

[Ianman]

If your crafty enough! Just make the block the size ya need, if you want send me a pic of the gun in question and ill try to help!!Lata

[Wingmaster700]

Does anybody think a CO2 paintball tank will work. I dont know too much about paintball but do you think you can hook up a hse from the ASA fitting on the tank to the end of the air gun

[Ianman]

I think it would work, but if your using air in the tank, it prob wouldnt last but a few sec, co2 would have more psi and last a bit longer.

[ceobeeswax]

what were the measurements on the vortex chamber??

[Ianman]

see link on page, here it is again..........http://www.burntlatke.com/bb.html

[BOMBOMBOMB]

and i also forgot.. i was reading ur replies and soemone mentioned abut how much u said cost bla blah blah cause of brass fittings... I didnt here anythign botu brass fittings in ur instructable and thats sayign something. sorry if thsi sounds really mean but its more constructive critisim but nice job aye got me intruged cheers nato

[Ianman]

Section one of the instructable is were I mentioned the brass fittings, I didnt specify exactly what I used because you may not be able to find all of them and will have to substitute and come up with something on your own that gets the job done.

[ceobeeswax]

true!! hey what

[BOMBOMBOMB]

Hey nice instructables but if u wanted oe of the bad asses instructables on instructables id redo it with step by step construction much easier to understand and include ur paintjob its sick... im just nto too clear on the T bit like hwo the caps on each end are setup..... anyways u really should redo this with step by step instructions!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! cheers nato

[Wingmaster700]

hop up helps put spin on the bb so it doesn't sink in the air

[ac1D]

I dont think they are accepted in a airsoft field, a metal bb would do too much damage! (shoot one in your hand)

I made one that look almost the same, exept it shoot plastic one. i used these small CO2 bottle they are selling at STAPLES
(here)
It work pretty good, shoot really quickly ( around 30/secondes ) and is accurate.

[Jonno]

Nice work man..

[knex hater hater]

holy crap dude. how much money did u spend. i personaly wouldnt make this and just buy an electric one for just 30 thats full auto. I mean it would look like crap next to this badass gun but idk if people are gonna build this. well you just never know. nice job.

[kinghack]

hay man i live in australia do u know were i can buy a bb gunthingy i have wanted for ever of a website 2 buy dem thanx nice dedign can u please explain the vortex block 2 me a bit clearer in detail

[Mad Cat]

You can't buy them here. They're kind of illegal. I got mine from Europe.

[Wingmaster700]

Hey, what did you use as an air source

[Wingmaster700]

About How much did this cost

[Ianman]

To sum up both of your questions, I spent about US $50 on the parts, the majority of it on the brass fittings and PVC cement/primer.Not to mention the old BB rifle I already had; and the vortex block was made from bondo, I linked the site i learned that from in the instructible, but here it is again.........http://www.burntlatke.com/bb.html
Thanks for your comment, let me know if I can help any more!!!!!!!!!!!!!

[Wingmaster700]

waht did you make the vortex boout of.

[DIRTYSHOTZZ]

YOU ARE A TOTAL LEGEND Since i live in australia wee have very high restrictions on weapons of any sort but i make my own guns n stuf ill make it then tell you the rest

[Ianman]

Sorry for the confusion, this is not an air soft gun. It shoots REAL metal BB's.

[yofooshitter]

hey thats awesome ive already made a gun like this out of a potato gun n using straws as the barrel but they always rip even though i could shoot airsoft through plywood. where did u get your barrel?

[yofooshitter]

do u kno where i can get a barrel for cheap cuz i checked airsoft websites and they cost like $50

[Ianman]

My barrel came off an old bb gun, but you could try a hardware store and try to find some aluminum tubing, or try a salvation army or yard sale for an old POS bb rifle.

[Whaleman]

wht size bb does it shoot? 6mm, 4mm....

[Ianman]

Sorry I didnt specify, It shoots METAL 0.177 inches (4.5 mm)BB's., I have never owned an airsoft, but I think those would be too big.

[Whaleman]

thx

[knexpro7]

!!!!!!!!!!!!!!!!!!!!!!!!!!!

[gunmanx]

lol i can hear in the back round ur listing to baracuda - heart lol i lovve tht song

[knexer1]

This is amazing!!!!! I have already built something similar to this for airsoft, but this is just incredible!!!!!! Nice work

[Ianman]

Thanks, If you need any help along the way, feel free to ask!

[knexer1]

actually I just finished buying the parts on sunday and built it on monday, but i still need a few parts for my air compressor (an air filter and a universal coupler) and it will take me a while to save up enough money, but i'm pretty sure it will work, but thanks for the offer.

[wingman246]

about time this instructable came along, I HAVE to make one of these

[Ianman]

Let me know if I can help!
