World Web shooter shop class - Part 1

[MarvelFan1]

I am only ten, but I want to be a engineer when I grow up, so I could help with the shooters, but not that much with the formula.

Cool, I want to be an engineer too! Anyway, does anyone know where I can purchase polymorph, helium valves, and Velcro straps? Also, I dont have a home depot, just a lowes

i dont know if you can se the images but here is the explanation of them
From 1-4 is the pice that I told widow it might work for the shooter
From 5-8 is my web shooter and the white part is the membrane and I made it in order that every time I join the 2 pats of it it lights up
so tell me guys what you think of it

I'm only 13, so I don't think online shopping will be an option for me.

If you guys are using co2, you could make refillable cartridges that you can fill with those Co2 bottles they use for paintball. Here is a good site to get them from. http://www.co2cartridges.co.uk .

Hey guys, how are you going to shoot the fluid out anyway? Maybe I can help.

 

[ng.samuel]

Hey, what size tubes are best to use? I apologize if this question has already been asked. Also, the solenoid valves that I have looked at are quite chunky. Is there any way to amend this and make it slimmer? Perhaps it's possible to open um the casing around the valve and fit the solenoid into a better casing? Would this work at all and if it does would it have to be done in a certain shape?
Thanks

did you draw that?

Nope,its a concept art from the movie.

The choice of using the positive charge as the outer thread is so that the overall charge of the final thread is positive. That's preferable so that the final attachment point has some attraction to the wall. Makes it stick more. As long as you tilt the positive streams slightly towards the center it'll be fine. Not much, but enough.

I can definitely recommend that nobody try to refill a co2 cartridge. It is HIGHLY dangerous. There have been attempts by companies to make refillable cartridges but those too are dangerous. I've researched this and people have made homemade adapters and the like but there really is no safe viable option for refilling co2 cartridges. Just buy new ones. by trying to refill them, you're risking your fingers, teeth, and probably eyesight in order to save 58 cents.

Quick question, what size CO2 Cartridges is everyone using? I only ask because I'm looking to buy a ton of them for testing purposes and I want to make sure that we're dealing with roughly the same designs.

 

[White_widow]

To jam: It rather depends on the way you plan on pressurizing your fluid. If you are going for an easy way to do it, use a schrader valve and a bike pump. If you want something a little stronger, use the same valve, but use CO2. As always, if you want to avoid the hassle of pressurizing, find an electric pump. For myself, I will be using a mixture of bike and CO2 because it gives me more options.

In short, what you need to do is find either a pump or valve.

 

[jamisicus6]

I've not really looked at the propulsion system yet. How is that system going to be set up? Will it be two canisters, one with CO2 propellant and another with the fluid or will the fluid be pressurized using the CO2 prior to use?

I'm using 12g unthreaded. threaded seems to make them a whole lot more expensive. and 16g will give you more pressure per cartridge but seems to make the price per cartridge alot higher also.

For the test run, I used a basic bug spray tank that you wear on your back. I pressurized water and it worked fine. At higher pressures, the water split apart. I'd start there in your case. That will allow you to see how these kind of devices work. I know how to build a shooter because I've been opening up aerosol cans and investigating how they work. There are only two kinds.

1.) The kind with a straw.

2.)gravity fed.

The kind with the straw rely on the propellant pushing the liquid through the straw, and of course the propellant is in the top, pushing down on the fluid to get to the straw on the bottom.

The other kind relies on gravity. This kind of pressure vessel MUST remain with the release valve on the bottom. It's like whipped cream. The can must be tipped, else you'll be tasting nothing but nitrous oxide as the fluid rests on the bottom of the can.

When engineering this, just remember that air will always find the top, even if you turn the can.

Just to throw this out there if we ever run into a problem where the propellant will react with the fluid there is another form of aerosol called a bag on valve. Whatever you're spraying is in a bag that is surrounded by the propellant.

 

[White_widow]

That's awesome. That person deserves a medal.

 

[White_widow]

Ok, so to SUP Kudos.

this picture:

Is EXACTLY what a web shooter is supposed to be. A valve and an actuator connected to a fluid source by a line. This is what I did with my tilt valve. (I wish I would have shown you guys my shooters working before I broke my tank)

Anyway, that is what everybody needs to work on right now. Make the valve, the actuator, and the tube.

 

[Bdude101]

Good, I will start working on that.
