How to Build an AWESOME Propane Spud Gun

In this video I show the process of making the potato cannon that will serve as the main gun of my 40% scale tank.

[@fadesevar2809]

not bad do you have any large project ideas for after this is completely finished?

[@MacroMachines]

yes, and im really excited for the next project, but you'll have to wait and see :)

[@frootzbootz6372]

RealSteel 1776 im guessing its a mini battleship that floats and can drive?

[@Rusoatrincherado047]

Is too much to ask a KV 2?

[@davidhansen9665]

For a young guy, its awsome to see your able to use welders and grinders etc and fabricate something, must had good parenting

[@landondavid5773]

Couldn’t have said it better myself. The lack of parenting as well as big tech and social media influence will surely run this world to ruin. I believe much sooner than people think. I mean we’re literally watching it happen right now before our very eyes. Anyone who’s actually paying attention would agree. God bless.

[@rougarou1117]

I like your ingenuity. I'm sure you have tested it plenty now to know this, but you should have no issues with the structural integrity. It is overengineered, which is great for your application. I spent 10 years building these out of PVC and never had one fail on me. Great work!

[@zebulynbeattie5516]

I watched the entire series on building the tank start to finish in 1 night

[@sallymorris2914]

me too

[@MrStuartmclean16]

Cool video, you could try a foot powered air pump/bellows setup for your fuel mixture. I don't know if that's better or not but probably easier than blowing into a hose

[@noah31270]

Hi,I'm a French 18y maker and I actually make a mini track tank where I can go and drive, I tank you because your video is a good help for my to build my tank! If you would like I can give you photos 😁

[@thecam0073]

Haha now I know how to plant my potatoes! Hey I watched your whole tank series and this video. Great stuff all the way thru. I wish I had your teachers. You really have great skills and always speak with useful technical knowhow. Your videos are the absolute opposite of artificial intelligence garbage time wasting videos on KZbin and that is why I subscribed. I picture an octopus-like tube inside the combustion chamber that funnels the propane to several spouts inside so as to eliminate the blow tube.

[@luisgatopreto4119]

Man... very good idea!! Excellent!!

[@MrHerhor67]

Probably the best gun on YT.

[@alexjurackovich2057]

Your creativity with this tank is amazing:))

[@madcowrebel4216]

This has got to be my favorite channell!

[@TMJ--hv3jl]

Can't wait to see that final product !

[@mateomikuljan7805]

You went all out dude amazing

[@maysterre]

I think you could make a different versions of turret and armament for example: AA Version, Artillery version etc. Anyway, great job.

[@gunner678]

The stick is known as a 'Rammer' and 'Breach Block' please....great video, well done....clever chap!

[@pargunar]

Nice original idea with the "blow tube". From my experience with potato guns, getting the gasses inside the chamber to get mixed together propperly is usualy solved by a small fan inside it. But the blow tube really matches the simple and funky design you got going, I love it :p

[@patrickmihajlovic4112]

joel håkansson.... Yeah... maybe... !?? But would work by FAR BETTER, if he didn't shut the valve in front of the combustion-chamber before trying to blow through it... !!!!! 😂😂😂 (Opening it at 13:12 closing emediatly after that at 13:16 !??😂) AND btw... even with open valve it isn't working like pretended out of another VERY obvious reason ! 😎😂 NOW i give you the challenge to find it by yourself to save the tiny rest of reputation ! 😂😂😂

[@hellishgrin4604]

I really hate people who use propane as a none combusted propellant (obviously he does ignite it here). First of, I think it's a waste. Second, while it is considered a "clean" gas, I don't like the idea of it needlessly being used. Third, its potential far more hazardous if it leaked or ignites. I just think there are far better options. Great vid.

[@meltonenterprises6761]

Great job brother. I love seeing all your projects. Keep it up.

[@philipdebacker]

I love it when a plan come together … 😉

[@CommanderMoon]

The tank is looking amazing

[@Ivangomez-bo7vs]

I know this would be hard to replicate, but you should try to make a falling breech block cannon, just to add a touch of realism☺

[@gunner678]

Ivan gomez something like the cap of a Grolsh beer bottle, but fixed and operated with a lever, easy!

[@Mauserguy85]

So damn awesome!

[@rizalardiansyah4486]

where are you going to put all the potato rounds? that turret seems very cramped... sorry if bad english...

[@axlemarley3082]

Rizal Ardiansyah that was actually better english than most of my friends speak. and i live in the us xD

[@rizalardiansyah4486]

Axle Marley thanks, that makes me a little bit more confident

[@axlemarley3082]

Rizal Ardiansyah no problem man =) glad i could make ya feel better about it!

[@hibahprice6887]

Test ways to purge the combustion chamber.. I had an idea with a homemade turbine, or with a carburetor that would inject the finished mixture into the propane / air

[@martinwest9172]

Wow. I'm so happy to have som help fore my build, keep up the good work

[@mikes4564]

That's freaking awesome. Love the shop! Gonna have to piss the wife off, me thinks....

[@u_solutions_lv]

If you use isobutane as fuel, it has very narrow stechiometry. it only ignets 1-6%, and detonates only at roughly 3.5%. So basically it either shoots or not. Also for PVC home depo kids variant, the barrel is too short. that makes it go loud and bang, but if use like 10ft barrel instead of 2-3ft, you get quite a velocity, of around a 12ga standard slug. what are combustion chamber dimensions in your variant? I guess you can shurely doubke barrel lengh if you would switch to building a SuperPershing instead

[@NudeJawn]

seems reasonable, good job.

[@southernwulf6983]

I was wondering on witch type of potato gun i was going to use,but it seems like this one is safer. Hope to battle with u one day

[@zebulynbeattie5516]

I liked all of your videos

[@gilbertodiaz-castro626]

Genius.

[@6bettyboo9]

Super cool !

[@neh5957]

I was thinking for ammunition you put an custom made a.p shell then an m-80 behind it but you light it with something like a spark plug

[@aac9258]

Hey ATF, I am totally gonna tell you guys when I make one of these.

[@lukem2452]

Very cool, what kind of range do you get with it?

[@alphanukleus3447]

Spudguns are illegal in germany ( ཀ ʖ̯ ཀ) thank you Merkel

[@marcox4358]

is it legal to build a mini-tank like this one in germany? I want so bad to build a Panther

[@alphanukleus3447]

They are illegal because it is a device that shoots a projectile through a barrel and thus the definition of a gun is largely fulfilled. You are not allowed to build guns ("guns") here without licens (gunsmith)

[@alphanukleus3447]

It is, of course, legal to build a mini-tank in Germany, but it can be difficult to get a permit to drive on the road. I do not know if it is legal to build, which looks like war machines.

[@rbn_hmrs541]

no prob with this but you are not allowed to armor it just take a old chassis (the rules for a vehicle are the rules the chassis had when it got manufactured in germany) so just take a Käfer or beetle in us and mount that stuff on it the only problem will be the tracs and the "TÜV"

[@marcox4358]

+EnduroRookie what is a Tüv?

[@hibahprice6887]

Will the pressure in the tank affect the result? And even if you pump fuel, the maximum that will be, it will not shoot. No matter how it can explode, there are a lot of holes in the barrel and a projectile in the form of potatoes, the friction force of the potato is in no way stronger than the walls of the combustion chamber

[@fuyoki_san2692]

good job m8, but question are you going to make the mixer automated? it looked like you were struggling to put air in the cannon

[@MacroMachines]

its not that difficult to just blow in. I wanted to use a small fan, but theres no convenient place to put it

[@fuyoki_san2692]

oh ok

[@lshssprings]

Can always use a hand pump like a manual blood pressure pad uses. Would only take 1 or 2 pumps with it to mix up the propane, it would also add a bit of oxygen in it instead of carbon dioxide from your breath to make the blast a little more powerful. That in turn could allow you to drop the pressure of the propane to maybe 25psi and get a few more shots from one tank.

[@thehackmycomputer]

lshssprings the blood pressure bulb is a genius idea. Well done.

[@bsb0011]

@@MacroMachines Why not use a fish tank air pump? Would easily run on 12v used for to start the tank. Just flip a switch and good to go. Mount the pump to the front plate holding the cannon, along with a strap to hold the propane. I'd add a clamp for the ram stick and a small basket to hold several potato "rounds" as well.

[@Shadow_Hawk_Streaming]

I'd love to see a proper breech design,perhaps this could be a future project for you, to improve your cannon design further

[@barrettbachner8657]

this is really cool, but why not use a pneumatic cannon, you can get the same if not more pressure and projectile velocity, but its more reliable.

[@trombb8782]

you can use carbon fiber composite to make pleasic tubes same strong like metal but ligthweght

[@slopedarmor]

Still an awesome spud gun! Wish they weren't illegal here :/

[@alphapennsylvania9439]

It's rather going to be a epic potato cannon or a over built pipe bomb.

[@samuelmunoz2636]

It is looking amazing I just think that the gun looks a little thin, you put more thickness and a muzzle break?

[@alexjurackovich2057]

That's awesome i wanna make one of these.

[@migueltorres5925]

Very good very good

[@aidanwilson9832]

Good project to make using my powertig

[@spectre7529]

For the spark plug what tap size did you becuase i cat find a single thread size online?

[@kingscorpion7346]

the only question i have is: why didn't you include this video with the series on you building the tank? I had missed that part.

[@qualitycontentchannel4443]

are you a genius?

[@jackburleson5710]

Nice man

[@hazza1512]

amazing

[@animatedman883]

you should make a hatch for the tank

[@rateyesmertz3785]

Duden your tank looks lkike a Darlek.

[@tryingtoreachyouaboutyourc6161]

I have no idea what I'm doing, but im still gonna make this...

[@theonlymann1485]

Next, use arduino to make a autoloader

[@edit_phonk_anime1]

this is good for gang war in my country (tank battle) and HE shell

[@mateomikuljan7805]

Is this gonna be a tank used in like a parade or an airsoft tank

[@FBPrepping]

I suspect someone around here doesn´t has too many Airsoft friends...

[@gremlin3362]

Bravo

[@SwillTheDrill]

Isn’t using propane a bit dangerous? I remember reading about a guy who used a few metal pipes or something to make one and died as a result of it exploding, expelling shrapnel into the poor dudes neck. Died on the spot.

[@benniehazelwood3088]

cool work there try to make something else thin patados lol.

[@MatrChif]

What would be cool if u changed out the barrel to fit a nerf whistle football

[@hetboeitniemand6166]

Okay now do raids with it

[@bojangoranovic4309]

could you use that cannon what you made before for that tank?

[@rbn_hmrs541]

get a little cam and a monitor too aim and a arduino to control it and automate the loding (ok the loading think may be a little hard i guess ;) )

[@alphanukleus3447]

great idea an old hobby telescope will perhaps also do the job for a budget

[@rbn_hmrs541]

na you couldnt control it from the driver seat

[@alphanukleus3447]

no blin i mean a small thin telescope mounted parallel on to the barrel and a elbow piece to look through And crank handles to adjust the height and swivel

[@rbn_hmrs541]

you mean 2 elbow pieces and when turret 180 degrees you have to turn ya head 180 degrees and thats fucking up the picute it would be a pain in the ass to get this working so just use a old webcan little binoculuar thingy and a ebay tft wth the steering of the arduino it all would be around 70 bucks

[@alphanukleus3447]

GAH! he needs a bigger turret so one man can sit in it and act as the cannonier

[@ridhotrepamungkas7834]

good luck

[@shawn_hope]

think you could sell them?

[@carlneurauter5127]

Now what you need to to do is make sabot rounds for it

[@axlemarley3082]

what do u think of the idea of a full sized tank with a potato gun? cause its something i want to do and i want someone to tell ne how crazy i am xD

[@gamingghosto8494]

Could have made pre loaded shells filled with propane and made them like real tank shells

[@monicazamora254]

how much does an abrams toy tank cost

[@k.i.e1206]

You better use potato gun

[@522alien]

i see its a blank rifle :( your pressure is too high or patato is still inside chamber so it just explodes

[@PostalPatriot556]

This is cool, but over complicated. I think you be better off making a breach loading mortar tube and using mortars as your projectile. That way you have a Big Bang, smoke, and a pop coming from the projectile itself.

[@TonyWony]

You got that idea from me?

[@skits_n_gravy8961]

How much

[@Writer_Treee]

Make a kv 2 tank with a 100mm potato gun

[@captaincole4511]

Just made a simple one out of PVC and it cost 80 DOLLARS!

[@milanoosterink7548]

first like! will i also be the first to be replied by you? Legend says everything is possible!

[@msrodrigues2000]

Why potato? When I build my compressed air cannon I used balls of wool line surrounded by tape, this type of projectile could easily destroy wood panels and bricks

[@IdealIdeas100]

you talk about wanting consistency in your shots and regulate the gas, but then use a really simple and unregulated way to mix the gas with oxygen which feels like it defeats the purpose.

[@davidmorgan8612]

You should not have to have a tube to blow through to get the propane pushed through. Time to redesign, way to complicated.

Next time you put all that effort into making a metal disc just know your Google search away from finding metal discs of any thickness in that size range it can be bought for less than a dollar a piece

[@Alcantara2048]

Hello

[@CarterBrixFilms]

savage ... cutting metal with no gloves

[@ThishandlefeatureISdumb]

Horrid reload time ;)

[@coaster184]

Do you really think you can blow through a check valve that's being held closed by 30psi? Edit: actually it wouldnt be 30 psi by the time it expands in the combustion chamber and by the size of it the pressure most likely is cut down by more than half, probably low enough your lungs can overcome it. Nvm my other comment. I bet you're still losing pressure around the spud core though.

[@jaycobfoyel5073]

Don't waist your money or time with this method pvc works just as well all you have to do is attach a pressure gauge to your combustion chamber to control how much propane you put in.

[@kalleklp7291]

You don't have "a known amount of propane each time.." Ever heard about pressure changes? Is the pressure in the propane tank the same every time? Is the temperature the same every time? The list goes on and on..

[@jsugar72]

RELAX - the idea here is to produce a regulated pattern within a target range.
