POTATO GUN!!!
 

PLEASE READ THE WHOLE THREAD!!! IT HAS REALLY IMPORTANT INFO TO USE THE GUN SAFELY AND CORRECTLY


yo wassup guys i had recently expierienced a potato gun that me n my homie had made. i didn't think that it would be all that great and its an immature thing to ---- around wit but damn! after 2 weeks of talkin about making it we've finally made it. i don't have any pics of it right now but i will have some pics up asap!
so let me tell u guys about my expierience...so my homie tells me lets go make one so we headed over to home depot and got the parts which consist of ...
-3 feet of 5 inch PLUMBERS piping
-3 feet of 3 inch PLUMBERS piping
-a bbq ignitor ( u can use one from an old bbq if it has a starter on it)
-bottle of plumbers glue
-a reducer
-and a screw cap for the piping or whatevers iono u'll see it in the pix

so yea first u take the 5 inch piping and cut it in half, this will be the chamber for the fumes, and than after u cut it in half, drill a hole about the size of the bbq ignitor and put the ignitor in to see if it fits. if it fits than take the plumbers glue and and glue around the ignitor and insert it back into the drilled hole. when inserted back into the hole, check to see if the ignitor sparks. if it sparks than your good. after inserting and making sure it sparks glue around the ignitor on the outside near the button. make sure its a thick layer of glue and let it dry. doing so will keep any heat from piercing through a thin layer of glue and burning your thumb when shooting the damn thing. after letting it dry, take the 3 inch piping and the reducer and glue the 3 inch piping into the reducer. glue it really well so it stays good and secure after drying. after glueing the reducer and 3 inch piping together, than glue the reducer and 3 inch piping to the 5 inch piping also making sure its secure after drying. when all dry, glue the bottom screw housing piece? to the bottom of the 5 inch piping and wait till it drys secure also. when all that shiet is done hammer a nail into the 3 inch piping near the reducer so it keeps the potatoes from going to far down.

so now that its all put together now its the moment of truth! lol :y >:D get the biggest potatoes u can get from the store and shove it into the 3 inch piping end. when it makes that queef sound when pushing the potato down the piping that means its gonna be a good one. so anyways u can push the potato down with a pole or whatevers till it stops at the nail u put in there. than unscrew the bottom cap and spray any flammable aerosol or however u spell that shiet such as hair spray, axe body spray etc...into the bottom and screw the cap back on we have done test and found that axe body spray is the best way to get the best shot tite and aim up and push the ignitor. the potato will shoot out and high speed and that shiet will make a loud boom! lol

WARNING! dont shoot at people or anything that can break. shoot in an open area or at a brick wall or something. this can seriously cause injuries so please be careful. also!!!!!! if the potato gun doesnt do shiet when u press the ignitor please done point the gun at anyone right after or look inside the gun. the gun may still shoot!!!! so if this does happen, unscrew the bottom cap and put more spray and close it again and attempt to shoot the gun again. if it still doesnt werk that means theres too much spray in there. so take off the cap again and spray more axe and ignite the ignitor with the cap off so it can burn off the extra fumes, and make sure the gun is still not pointed at anyone this should help to fire the next round. also if intense heat burst through the ignitor area again, than stop use and put more glue around that area. also please do not use anthing other than axe or hairspray. i am not sure what gas or propane will do and it could be very dangerous so please do not use. we know axe is safe to use so we recommend that to use

last but not least!!! have fun wit this shiet!! ITS ------ WORTH YOUR TIME AND MONEY!!! BUT PLEASE USE RESPONSIBLY

Re: POTATO GUN!!!
 

you got that all wrong. you need to put a valve stem in the fume chamber and fill that bitch to about 200psi.
this one is a little different because we didnt have a valve stem, but you get the idea. ive also made them with gauges. hairspray/gas/lighter fluid has nothing on an air powered potato gun. I cleared a restraunt, intersection, another restraunt, a gas station and into a house with this fucker. (about a half a mile)

Re: POTATO GUN!!!
 

really? hMm....ive never heard of them made your way is there ne way u can post the way u make yours and maybe i can try it out. lol but yea the way i do it is pretty cool cuz at night u see a fat ass flame and a u get a big ass boom outta it but yea yours sounds pretty sick

Re: POTATO GUN!!!
 

i prefer propane.

Re: POTATO GUN!!!
 

I have always used my mini gas/oxygen (on a plastic style backpack) as propelent. .. it shot a can of beans through the tree in my backyard...

i also made a marble shooter with compressed air, that was sick.

Re: POTATO GUN!!!
 

fuk yea potato guns are the ----.

Re: POTATO GUN!!!
 

it isnt to difficult. just where you put the ignitor, put a valve stem. I used PVC sealer to make it seal from the inside, let that sit for about 20min then silicone the living ---- out of it on the outside. Let that sit over-night. works perfect. make sure everything is sealed really good or else its gonna leak. Make sure the silicone is good and sealed or else that ---- will be a mess. silicone it one night, go fire it the next night.

the best part about this, you can fill it up but dont have to fire it right away. so you can fill it, drive it to the ------- down the streets house and put a potato through his window. We used to shoot them at drive-thru's O0

Re: POTATO GUN!!!
 

I've seen plenty of those, but my company blows up plastic pipe for a living. We test the burst pressure and type of failure, etc. Anyway I just wanted to let you guys know that you really shouldn't use PVC, cause if the potato gets stuck and the pipe fails that ---- shrapnels like a grenade. You need to use poly-ethelene like the gas company does. If that ---- breaks, it will just bubble out the side. Great fun though.

Re: POTATO GUN!!!
 

ive built one of these before, had great results, used a 3ft 2.5" piece that went into a 4inch-2.5inch reducer, on the 4" side was glued with a 4" round piece about a foot long and a female end with a cap, just hot glued the bbq ignitor in and took that ---- outside, at least 80 yards and at night that whole fuckn thing would light up and sounded like a shot gun, just used hair spray.

Re: POTATO GUN!!!
 

AXE body spray works the best

Re: POTATO GUN!!!
 

ether is the best, its hard to get the mixture right though, it also works good if you put the potato in the tip of the barrel just enough to seal the barrel, then spray your accelerate in, then after the accelerant is in put the potatoe or lime ect, down the barrel with the hocky stick or whatever you use, this equals greater compression, and as we know, bigger boom! very nice

Re: POTATO GUN!!!
 

pnuematic's pretty sweet ;D

Re: POTATO GUN!!!
 

you steal my avitar bitch?

Re: POTATO GUN!!!
 

hmm i wonder what the diamiter od a soda can. frozen soda + potato gun = ...

Re: POTATO GUN!!!
 

:X

Re: POTATO GUN!!!
 

you have them all wrong. you need to build it with 2.5 inch exhaust pipe. with a 6x6 1/4 inch plate welded on the bottom. and a little hole drilled in the side to puta fuse in. dump picilo pete powder down into it and them put the potato. thats a real potato gun. not shitting you ask fook. i had a 79 jeep wagoneer. i was standing 30 feet way and shot a potato and it went clean through the windshield. when i say clean. it was a perfectly clean round hole about 2.5 inches in diameter. fucker would launch potatoes at my neighbors house which is prolly 700 feet away. but that potato gun ended up getting blown up when i put half pound of gun powder in it and 7 potatoes. yup fucker blew up like a pipe bomb. it was sitting on the hood of the jeep and pushed the cowl down prolly like 6 inches and the whole passenger side windshield popped out like two inches. anyways thats how we do it here in the sticks.

Re: POTATO GUN!!!
 

Yeah I would try to make it out of exhaust pipe for safety reasons.

Re: POTATO GUN!!!
 

I built plenty of those in my younger years but very simple design and you use hairspray aguanet for the fuel

Re: POTATO GUN!!!
 

damn, the exhaust pipe one sounds pretty crazy. I use to work at a golf driving range and we made some and those bitches were goin about 150 yards. take a golf ball and wrap it up w/ paper towel then stuff it in, that works pretty good for solid distance. my ignitor wasn't sealed very good and everytime i hit it, the flame would backfire onto my hand. kinda burned for a sec but it went away, haha. I'm gonna have to make one again. I heard you can get like a 1000 fine for havin one of these cuz it's considered a weapon.

Re: POTATO GUN!!!
 

Im sure you can but everything is illegal

Re: POTATO GUN!!!
 

no fag. i stole it from someone else on another site.

Re: POTATO GUN!!!
 

did he happen to have the same name as me :S?

you can keep it, when WTDR.com comes back up i'll change it anyways since i have had it for about 6 months.

Re: POTATO GUN!!!
 

it was called TAG!! i remembered it that night.

Re: POTATO GUN!!!
 

ya, i always use the black stuff (thats what your talking about right?) we used the white stuff and had one blow up once.

Re: POTATO GUN!!!
 

The "ABS" or as many call it Awsome Black Stuff, is much stronger, but also more expensive.

Re: POTATO GUN!!!
 

ok.
and no, it came from a guy on a local board. I will probably find another JDM avatar soon though.

Re: POTATO GUN!!!
 

tshirthell.com has some funny shirts that you can make into an avitar. that's where i found that one.

Re: POTATO GUN!!!
 

abs is not stronger. it simply peels like a banana when its over pressured, and has NO pressure rating. also, whoever posted the ball valve pneumatic up above.. used a non-pressure rated garbage 180 elbow.

^^^^ 92"x2" barrel, 31" x 4" chamber. powered by metered gasoline (you guys know about the stoichometric 14.7:1 ratio ) and will easily put anything that fits, through plywood.

safe to 250psi, but will never make more than a 40psi spike being combustion.

being the only potato gun topic here, and the only guy who actually knows anything about it..

www.spudtech.com

t66 on civic < throwing a 2x4 150ft through a stone barn wall

also, anyone that follows the first post, you may as well use jb weld to make your entire turbo manifold. they're about equal in the safety department. and, there is no 5" pipe. measuring OD of pipe > you, apparently. if you're going to use 2", 4 feet of it, and 17" of 4" pipe. NO cellcore. NO drainage pipe. them = not safe.

you guys like to make ----... make some potato guns. $30 is more than enough to put one together

Re: POTATO GUN!!!
 

I like how most of us can build spud guns that have a longer range than Hezbollah rockets ;D ;D ;D

Re: POTATO GUN!!!
 

i know i dug up an old topic, but it's the only relevant one, and most of you are really missing out on she shits and giggles these things can make. 2rd gear burnouts get kinda old, but destroying something with the caliber of a tank, doesnt.

i'll gladly write a PROPER instruction set to make a PROPER gun.. pneumatic or combustion. you guys are just too noobish to be introdruced to hybrids. basically, take a combustion, and put a union between the beginning of the barrel, and the chamber. sandwich aluminum foil in here, add fuel equalivent to the amount of bar pressure, and fire. power of 200psi with the explosive force of combustion.

15psi of air, 2 loads of fuel, = 120psi. 3 shots, 2 bar, 180psi. 3 bar is just not safe.. 250psi.

2.5" pvc will shoot tennis balls, and SDR-21 1.5" pvc will fit golf balls nicely. SDR-26 is a hair looser (.015 or so above golf ball size of 1.64-1.68")
3" will fit pop cans, 16-24oz pop bottles. 4", is rather huge..

Re: POTATO GUN!!!
 

hm.

testicles

Re: POTATO GUN!!!
 

You should take some good pics of your setup and a good write up that would be badass, I've always wanted to make one but never really looked to much into it, mainly because I know I would get in trouble with it. I tend to do stupid things. ;)

I'd suggest making a new thread though especially if the original poster's directions are crap.

Re: POTATO GUN!!!
 

i've gotten the best results by using the valve stem trick, along w/ white lithium chain lube. spray some lube in that bitch, pump in some air for about 2-3 seconds, and hit the ignitor. we measured one and got about 500 yards out of it
