I made one last summer. Dug it up for New Years and put it back together fairly hastily. Looks pretty fucking Orky now as a result because I didn't want to re-wire the fire control box for just one night.

I wrapped the thing with Gorilla Tape, so the shards would stay relatively contained if it went south. I do recommend pressure rated pipe, though.

Propane fuel. Tailored the fuel-air mixture with a bit of math and a spare CPU fan to help circulate inside the chamber. Even with a 6ft barrel it can make your ears hurt. Damn powerful.

One, time I loaded my potato cannon tree of life root, and fired it into the Berlin zoo. The Bonobo's naturally died from the scare, that is, they got completely panicked from knowing that wouldn't be able to have sex after the effects of this, so they killed themselves.
But one Baboon ate the tree of life root, metamorphisized , and ended up killing a ton of people. They blamed Putin and the KGB.

under the "mk II", is that like a drink bottle top? A weak point for pressure to escape from incase too much pressure?

>>28612840
Cap worthy
>>28613097
No, it's a circulation valve. A larger one from a Gatorade bottle is on the end cap. Fan is turned on with the wire pair in >>28612693 and vents the exhaust gases after each firing. Caps closed, propane injected from the 1" canister via ball valve, and then fan mixes fuel even in chamber.
Not worried about overpressure/KB'ing, because it won't ignite if you add too much propane, and I used Sched 40. parts.

I built one when i was 14 that put potatos through half inch osb at 20 yards. I went through my garage looking for the spray can that had the most warning labels on it. Good old carb cleaner. Didnt explode but burned out the threads on the rear cap. The barrel unscrewed so you could breech load it by pushing it down on potatos cut in half. It shaved the sides and made potato mini balls.

Literally everything used to make carb cleaner is flammable.

that design is shit.
you need to add 2 5" and 2 3" radiator clamps, 2 3/4" 2 smooth, bottom threaded tee's, and 8 threaded male/threaded female 3/4" connectors so you have handles. The BBQ lighter fits perfectly inside the smooth side of the Tee, making it like a trigger.
>>28613452
>Using sewer pipe.
You get what you fucking deserve if you can't pick Sched. 40, which is fucking everywhere and will be more than strong enough for common propellants.
Don't use oxy-acetylene, the tube can't handle the pressure
>>28613603
The design is essentially what I used, sans 1x12" staging chamber and Propane tank + hoses. It keeps costs down with a basic straight pipe. If you wanna go full fgt and do a sweet wheeled carriage or carrying handles you add more money. Being modular is what makes these so easy and fun.
>>28613624
>Oxy-Acetylene.
It's doable with Sched. 80 if you do a straight pipe. If you trombone style you will blow the elbow eventually. Low charges are fine, but that burn rate is scary shit, anyone who has that stuff should already know what they're doing.

Combine wicked fast burn rate and energy density and you get giga-nigga pressures that kill cannons and may or may not kill you too.
So, potato guns are all legal and good fun, but I want to bring it up a little, as in I want to launch beer cans full of cement at things.
Would this be legal, and do you think 1/4 inch steel walls are enough? I only started toying with the idea a few days ago, but I want to line up a bunch of stuff and see if it will make it through, like 22plinkster does.
>>28613849
Worked our way up from AXE in a 2 inch pvc pipe with a lighter ignition to propane. Eventually bit off more than we could chew with a rig we nig rigged from an old hydraulic cylinder and piece of exhaust pipe.
Acetylene filling went fine but when we were pumping the oxygen into it some oil inside diesel'd. The exhaust pipe KB'd and ripped along the welded seem, flew 50 feet, bouced a few ti,es along the way and fucked up a quad. We all got knocked on our asses and burst one guys ear drums.

>>28616392
Yep, made one out of a couple pringle cans. Only fired it a couple times, it kinda failed at it's intended purpose (scaring geese away from our pond).
Judging by the fact that you can (apparently) build spud guns legally without registering them as destructive devices, I take it that potato guns are not considered firearms by the ATF (I'm assuming that's because they're purely for entertainment and thus not "arms"). Is this correct?
And if that's the case, could I legally build my own full-auto potato gun for shits and giggles?

>>28616991
Perhaps build a device to place in the potato to house the propelant? You know, like an aluminum can full of hairspray or oil, and there's a small hole at the base of the can. This can is thus placed/taped behind a potato or other projectile. Make a large doublestack mag with a good spring and all you need to do now is figure out how to ignite it. I'm thinking of something like rocket file for model rockets. If you fill that in the holes on the can then have an electronic firing system that'd be good. Find a smaller pvc tube and build a breach that moves back with the gas. Bam. Done. Low rate of fire but you still got a auto tato.
>>28612961
>>28616991
you can use a pringles can for casing.
poke a hole in the bottom and stick an electronic lighter spark thingy ftom the inside, so that it is visible from outside but slightly recessed.
now insert a balloon filled with flammable gas inside the can, directly over the igniter.
add spud, push it to optimal depth.
Now, design a launcher keeping in mind you need a long enough nail to puncture the can and the balloon before the real hammer hits the igniter.

Other brilliant ideas.include using starting fluid, and oxygen acetylene mixed gas.
Bumping this thread.. I wanna build one, but life is in my way
Had built a combustion powered plastic pipe spud gun when I was around 14 and used it to plant potatoes and apples from 300 meters away across my rural neighborhood.
But I'm more adult now but still enjoy stupid things like spud guns. But I have far more experience and tools at my disposal now, so I'm thinking of of building a new spud gun out of steel powered by the combustion of oxy-acetylene or a fuel system using a fuel injector from a car squirting high octane liquid fuel into the combustion chamber. It would be fired by means of modified car spark plug wired to a custom high voltage system.
I'm just wondering if anyone of you has seen anything like this built before, and if you have any advice?
does anybody have the cap from the rocketanon who blew up a fence and made green napalm?

We may have a winner
Loads of fun. Though if I have a kid who wants one, I will personally fucking weld him up one out of steel because Jesus Christ do I not trust that shit now that I have an engineering degree.
Funniest story I can think of off the top of my head is this:
Buddy and I decide to improve the ignition of our spud gun by using a shitty $5 stun gun. We wire it up to bolts that protrude into the chamber, sealed with grommits. The tips intersect and form a spark gap.
We go to fire it, and he decides to hold it from the front while I perform the necessary rites and rituals at the back. Once ready, I fire the thing. Only it doesn't fire, because he's got his arm over both the terminals, so I just fucking taze the shit out of his armpit, haha.
>not one single use of a tazer for ignition
Come on /k/.
Back in highschool, we had previously made potato cannons, but they ether break, or get lost out on mine and my neighbor's land. We had also made some reinforced tubes for mortar fireworks, and I had a shoulder-able mortar tube I made from fiberglass. Anyways we decided it was time to make a new potato cannon. We built a standard cannon, used a grill starter, a length of 4" combustion chamber and about 10' worth of 2" PVC barrel. We used a couple squirts of oxy-acetylene from my neighbor's cutting torch. We used another 6" long section of the 2" to freeze ice slugs for ammo. Using that load, we would get about another 5' of blue flame from the end of the barrel and a very satisfying thump. This was followed immediately by the sight of that ice slug flying over a group of pecan trees near my house, at least like 500 yds away. Surprisingly we never shot anything point blank to see what it could do, but we never really got a chance. One day, another friend came by and wanted to shoot the cannon. So, we grabbed a slug, and loaded everything up like normal. What we didn't notice was that my neighbor's father had switched to a rosebud tip, and had significantly overcharged the gun. Said friend went to Rambo the damn thing with it over his shoulder, but he ended up bitching out since he was a massive pussy. To show him he was being a bitch, my neighbor grabbed it to fire it. He slung it down by his leg and aimed high, hit the starter, and BOOOM. The combustion chamber splintered out, peppered all of us, and embedded some shards in my neighbor's leg, ripping through his jeans. Thankfully that was the extent of the injuries. We made another cannon a few weeks later, but then was sure to switch propellant and double check the charges.

Don't mess with potato cannons guys
>>28617077
>Caseless potato
That would actually be great, but I think I'd want to use solid propellant for that instead of air/fuel.
>Doublestack mag
I don't particularly care about compactness, so I think the reliability of single-stack would be better. Or a belt.
>I'm thinking of something like rocket file for model rockets.
Good idea, and I could have electrical contacts on the sides of the chamber so that it will go off as soon as the potato is chambered (open-bolt, wooohooo).
>Low rate of fire
Pretty sure that's a given. Unless I do something crazy like a multi-barrel Gatling autopotato, anyways.
>>28617130
>Pringle can casings
Might have enough volume for air-fuel to work, if somewhat anemically. Extraction might be tricky, I guess I could hook it by the mouth. I'll have to think about this longer and decide whether it's worth it over the caseless potato concept.
>Balloon
That'd be a good idea for keeping air/fuel together (assuming the fuel isn't something that would attack the rubber). I still think I'd rather use a rocket igniter/E-match like the other anon suggested over a spark igniter, though.
>>28617291
>with pringles can as housings, I'd go for single stack.
Yeah, even in general I think pringle cans are the way to go. Double-stack requires a bit more convoluted feeding, and I'd rather not deal with it (with a real gun, metal-on-metal makes this easier due to lower friction and yet they STILL have problems from time to time).
>chaingun vs. blowback vs. other
I was sorta thinking chaingun for reliability. I'm not sure how much force/work it takes to chamber a potato (that's one advantage of the pringle-can cartridge idea; it would probably cycle more easily and consistently), but the recoil impulse itself and thus bolt mass, travel and spring tension characteristics are fairly easy to calculate (assuming spud mass and velocity can be estimated).
Thanks for the suggestions though, guys. Great stuff.
I fixed my potato cannon the other day trying to relive what I never got to do as a kid. I added a $8 eBay stun gun, about 6 seconds of axe bodyspray, and a racquet ball. It will fly about 300 yards

Looks awesome. How's the ballistics/accuracy?
Nigger-rig some explosives and you've got yourself a nice mortar.
when I was in high school I made a 4 inch barrel cannon once. I used a handtowl as a sabot and shot pretty much everything you can think of out of it. I even made some shells comparable to a giant shotgun to shoot airsoft bb's. The highlight was the golf balls. Since they are designed to be aerodynamic they fucking tear ass down range. I launched one and it kept going and going until I couldn't see it anymore. Launched a few more after that and herd one hit a tree about 600 yards out. It sounded like someone took a sledge hammer and smacked the side of a tree. Awhile later I found out about this wonderful thing called Ether and that it works alot better than axe. The only problem is that I could only get about 50-70 good launches out of my 6 inch combustion chamber using ether and the kabooms were starting to get dangerous. As soon as Girls and ammo started taking a toll at my wallet I could no longer afford to keep it running.
>>28623814
Haven't actually fired it with the new setup, just got found the stand yesterday. The old barrel was just 2inch pvc and I was getting about 150-200 yards.

Just had another ungodly idea... no idea if it could possibly work, but if it could then it'd help simplify things considerably and probably yield remarkably high fire rates.
So here it is... does anyone suppose it'd be possible to scale up the Cloud BBMG concept to potato scale?

It would require a very high-flow external gas source, but I have a few solutions to that (straight compressed air? Hybrid compressed-air/fuel combustion? Solid-fuel gas generator? Steam boiler? Plenty of options). But I'm not sure it's feasible to even get enough airflow through a cloud chamber to get potatoes to swirl around like little BBs would.
I accidently shot my cousin in the face with one. He was looking down the barrel and wanted me to flick the striker to make sure it was still making sparks. Well, he had loaded it right before it started raining and I guess forgot about it. The potato made contact right on his eyebrow and fucking exploded all over the room downstairs.
can you guys suggest some reason for why a spud gun wouldn't work?
I've made two but can't get them to shoot spuds, I can get it so that they'll almost always go off without being loaded though and I've already tried googling for help. Any ideas?
>>28626328
Like it's not igniting or it's just not making enough pressure to fling the tater?

Lucky you didn't kill him. All of the potato guns I've built were powerful enough to blow through wood fencing.

>>28626517
And your igniters arc fine and ignite the propellant without a potato?
Dunno what you're using, but try using less propellant, or maybe try a different, more volatile propellant.
>>28626733
I'm able to get a good loud spark so I wouldn't think of that to be the issue but I'll try using the propane I've got.
>>28613530
>>28613597
thats what i used. the first one i made i used hair spray and the insides got all gunked up and shit. then on a whim i used a scant spray of carb cleaner and it worked just as well as a good long spray of hair spray. i had no fucking clue how strong it would be.

Thing is, potatoes work perfectly in spud cannons because you create a gas seal by jamming them into the barrel (or in a casing, as already proposed).
Airsoft BBs are all equal diameter and rigid, so the jamming isn't required nor possible.
If I may ask: is there any solid propellant safe enough to ignite inside a pvc chamber? If so, it should be possible to make actual decent rounds with soda cans and toy gun caps.
Soda cans also provide a convenient extractor groove, and reduce round diameter to 52mm.

Is that some multipoint ignition?
You'll lose power that way. Ignite from a wall always.
>>28612443
helo
i am haveing of 1 question
what if someone uses ether truck starting fluid spray for propellant instead of hairspray?
>>28629126
is it like carb cleaner?
use very little compared to the hairspray.
>>28616392
Goes well in combination with tennis ball match bomb.
>Cut slit in tennis ball.
>Cut heads off a shitload of light-anywhere matches (light anywhere is important).
>Pack tennis ball full of match heads.
>Tape slit closed
When the tennis ball deforms on impact, a couple of the match heads will strike from getting rubbed on each other. Sudden heat + pressure = lots of flaming match head debris everywhere. Tennis ball mortar makes it possible at range.
>>28628863
>decent rounds
>soda cans
Why not just use golf balls? Small but not too small, hard as fuck, made to fly.
>>28629129
starting fluid is ether which is very explosive, im not sure what carb cleaner is.

The whole thing that makes me love the idea of a potato-chaingun is the "potato" projectile part of it.

I envy you completely.
Potato guns are fucking crazy. I remember engulfing my hand in flames, putting a hole in a fench, and stripping the paint off a garage door (the moisture of the potato stripped the paint straight to bare wood) by accident. They are definitely potent items. Some pvc pipes, a bbq igniter, hair spray & spuds and you're fucking lethal.
If you stick some nails, bearings, washers into the potatoes, you'll have a crazy high caliber particled slug launcher. Good times

Lost. Fuckin A, anon.
1) There is a Co. that sells rifled abs by the foot. Google it.
2) Learn about "burst disk" wadding.
3) Gas + compressed air is best. Use valve from bike tire.
4) tazer ignition a must, inner chamber mixing fan optional.
5) Always wrap with strapping/ gorilla tape
6) A chunk of barrel makes a perfect sized sabot mold wet paper slugs can hold anything and can be fired wet or dried.
7) lube your barrel! I use Pam. But ABS dont care about petrochem like Vaseline.
The burst disk is a thin piece made to seal the chamber and only hold 100 psi or so of air/gas before popping. This means your projectile doesn't have to seal the barrel as tight, this makes a safer cannon with out sacrificing power. Pump up till almost bursting then light it up. Requires an uncrewable barrel or breach load design.
Breach load masterrace!

>became a felon
How does shooting flaming potatoes make you a felon? Did you light the woods up or something?
>>28629309
It just so happens that in my country anything that launches projectiles with muzzle energy over 7.5 joules are considered weapons.
The only exceptions to this are bows and fishing spearguns aka "sports equipment".
Every weapon must be registered.
This usually includes the commercial denomination of the weapon. As it is a prototype, I don't even know what paperwork would be needed to register it, and frankly I do not wish to go through any paperwork just to build a fucking spud autocannon.
There are also laws against acoustic pollution, but even then, repeatedly exploding even small amounts of explosives (which are illegal to produce, funnily enough) or small amounts of fae would draw quite a lot of attention very quickly.
Would I risk becoming a felon just to see my glorious chaingun tossing mixed veggies downrange?
Nope.

>>28633623
Poke the uninsulated end of a really long wire into it and launch it, and have the other few hundred feet of it coiled up next to the cannon. Just touch the other end of the wire to a battery when you're ready to detonate. You could call it the PotaTOW Launcher.
>>28633623
I am fairly certain that once you add incendiary projectiles the ATF won't take your "i swear it's not a weapon" excuse so you'll have to pay attention to NFA DD regs.

On phone so fuck your meme arrows.
Me and a few friends were dicking around with this spud cannon, this was back when I was 13-14. I'd only used pneumatic spud guns beforehand, so I had no fucking idea what I was doing, apart from the basic idea behind them (mix fuel and air, spark it, boom).
anyways we were having a bit of trouble, so we decided to check if the shitty duct taped nails we were using as sparkers were out of line.
So I go screw off the back end, wait a few seconds, look in the chamber and yell at my friends to spark it.
Next thing I know, I no longer posess eyebrows.
Told my mum it was a barbeque so she didn't freak out.
>>28612961
I know it's terrible for me to laugh at this, but it's fucking hilarious.

>If I may ask: is there any solid propellant safe enough to ignite inside a pvc chamber?
Plenty - black powder, smokeless, KN-sucrose, APCP, whatever. Any non-caustic solid deflagrant should be fine if you employ it prudently, keep pressures within the safe range and ensure duration is well below that which might, err... thermally compromise the PVC.
