Making a 330+ Joule Air Cannon

[@jeremycrisp4488]

I've never seen a fire extinguisher with that large of an opening. Replace that silly little valve with a two inch ball valve and use a pneumatic actuator to open it and you will be blowing holes through car doors.

[@codyabbott1219]

What on earth is a pneumatic actuator and what does it have to do with a ball valve?

[@jeremycrisp4488]

@@codyabbott1219 do you know what a linear actuator is? They are like hydraulic rams except they use air. It will open a ball valve about 5 times as fast as your hand can.

Hi ! Be very careful using compressed air doing anything ! The Schrader valve can actually be your death sentence ! 😢

High pressure injuries?!

@@johnshipley1389 Hi ! Yes, It is just a piece of brass with a rubber o- ring that can shoot out like a bullet !

Brother home many psi a fire extinguser can handle

[@kepoland5392]

imagine what could you do with a compessor instead of a bike pump

[@winstonchurchill6506]

seen one in the workshop doh

[@yadjekim]

You've built the speargun from the Poor Man's James Bond. It was a large book from the 80's, showing lots of DIY "devices."

[@Mika_357]

Sounds cool, definetly gonna try to get my hands on that book!

[@yadjekim]

@@Mika_357 The Weaponeer is a more useful book, by the same guy, Kurt Saxon. Now days, having it will probably get you put on a list. 40yrs ago, it was a cool book of improvised devices. Anyway, stay safe!

[@mohawksteel2215]

very wise to not weld the tank. Simple but effective.

[@tedboyle8508]

Arc welding galvanized steel, like this pipe, damages your lungs with zinc oxide. This has to be done carefully.

[@mxcollin95]

Nice job! Love that you through in some math to analyze the performance. 🤙

[@sergiogomez3664]

Doing a few changes you can power up upgrading the airflow

[@altonlynch5464]

Pumping it up with a bicycle pump was hilarious. At Harbor Freight you can get an electric tire pump for 10 dollars. will a golf ball fit in it?

[@Mika_357]

I usually pump it up with my shop compressor which goes to about 9 bars. I only use the bicycle pump for pressurizing it to 13 bars afterwards, but even that sure is a good workout ;D. Whether a golfball will fit depends on the barrel you're using. But with the pipe I used it actually fits!

[@masterheke7339]

impressive, well done

[@brutusjb3814]

You'd be able to shoot the rod extremely far is the barrel of the air cannon was only a little bigger then it

[@vinceywinceyspider]

What about using a co2 extinguisher that's full.

Un gusto Amigo... Me gusta tu creatividad, sigue asi!!! Un abrazo desde URUGUAY

[@danielgreen3715]

Get it to fire 10 mm Steel Bearings rather than Potato Wedges then you will be talking 👍

[@WagnerUlisses]

I thought the compressor was going to explode with so many pumps hahaha nice toy

[@ArcheryGuy2]

Nice build

[@Mika_357]

Thank you! It was very fun!

[@brjplummer9415]

It sure sent that pipe a long way ! Did you get it back?

[@Mika_357]

After a bit of searching in the long grass I eventually found it, yess!

[@personanongrata2045]

Wife: honey when are you going to come in for dinner? Dude: soon as I’ve finished building and testing my fire extinguisher cannon I’m making for KZbin….. wife: I think we need to have a talk

[@NBC_NCO]

I like that idea for a portable tire inflater. Fill it up . Throw it in the trunk.

[@alotl1kevegas860]

How many psi did you pump it up to?

[@Mika_357]

I did 13 Bars wich is around 190psi, this was the maximum I was comfortable with

[@alotl1kevegas860]

@@Mika_357 Thanks for the quick reply. I'm building one of these out of a small oxygen tank from a cutting torch. It should handle 200psi with no problem, if yours held 190. Thanks again!

[@Mika_357]

My pleasure! In my case I was concerned about the car tire valve, it was only Rates for 10 bar max.(145psi)

[@江广志]

good job bro🎉

[@m.muvaffakismen1746]

valve is Tir valve??

[@Mika_357]

Yup it‘s a Tire valve!

[@AinHamra-hr3jd]

يمكن استهداف مجال اكبر اذا كانت مملوءة بالابر ضربة تغطي مساحة كبيرة

[@TheBlessedMeek]

You should use a fan when welding bro. That is some toxic smoke you're inhaling

[@barmeister3242]

jetzt mit 150 bar und gezogenem lauf

Valve is too small.. not dumping your tank fast enuff😢
