Does anyone have any plans or know anything about building a rail gun (i am not talking about a huge one that compares to military designs. i am talking about a simple one) i was thinking of something like this. i got the idea from another forum but am sketchy about the details. what you do is take a coil of copper wire (insulated or not) and wind it round and around so it is one long coil. attach to the coil another wire with a huge capacitor (like thousands of volts). hooks this shit up to a battery. the slug is composed of a magnatized piece of metal. like a length of magnatized steel. i will have the plans drawn up in a little while and i will probly post them tonight. anyone else have any ideas? like how big the capicitor has to be and how big the battery ahs to be? and how big the copper wire has to be?

Here is the picture. i linked it cause the picture is pretty big (demension wise not file size.)

i was thinking about adding in a transformer to step up the voltage. (is voltage or current the more desirable thing when trying to make an electromagtenic field?)

To get a magnetic coil to work the wire needs to have some sort of insulation on it... Magnet wire is coated with laqur so it looks like it has no insulation but it realy does.

I doubt you could get good results. Maybe if you had a ton of voltage /etc and set up a huge coil cannon or somehting.

actually i am kinda skepticle about the coils ability to make an electromagnetic field. will it?

What you are desribing is a coil gun or also called a Gauss rifle. Current is much more important when regarding electromagnetics. A steel(due to its iron content) or iron slug will work since they already will become attracted by a magnetic force.

the picture continues to work for me. it is kinda big so you have to move the scroll bars around.

what would be the ideal way to get a huge current with about 5000 volts?

alright please tell me if this will work. i got some help from poison on this one so it will be better than my last design.

materials needed:

-1 20,000-30,000 volt transformer (any idea on which type?)

-1 20,000-30,000 volt capacitor (any idea on which type? ie ceramic, radial, ceramic radial? that kind of stuff)

- about 15-20 feet of 5 mm insulated wire

- a length of .5 inch pvc pipe (will the pvc interfere any with the electromagnetic waves?) just big enough so when tightly wrapping the Cu wire around it it is completely encased

-now use my previous design but replace the battery with a 110v wall socket and add a 20,000 volt transformer before the capacitor.

any other thoughts (mainly what type of capacitor and transformer i should use) before i try and gather funds to put this together?

also is there any way i can tell which side the elec. flows out of the socket? like which side it comes from and which side it goes to when looking at the socket?

You obviously dont know much on the subject of electronics. Let alone high voltage/current either. Looks more like your going to kill yourself rather shoot any metal slugs.

well why in the hell do you think i posted a thread under the misc section entitled basic elec...? hmmmm tough one i'd say. what do you suggest to make a powerful electromagnetic field?

You still need to learn more about electronics before even contemplating something like this. Jumping right in to this kind of stuff can and will get you killed without prior experience. Go get a book on electronics, if you dont want to buy one, go to the library and borrow one. You really need to learn stuff about safety and how things work before doing anything.

How about using a 300k stun gun.
To make the rail gun work, you can't just charge the entire coil at once. You must have multiple sections of coils, so that the coil just in front of the projectile is the one charged, pulling it forward. This can be done by using the projectile(iron ball) as a current bridge to power the coil.

i got some help from poison on this one
If you didnt work on it yourself, how do you know how to control the situation isf something goes wrong etc...

-1 20,000-30,000 volt transformer (any idea on which type?)

-1 20,000-30,000 volt capacitor (any idea on which type? ie ceramic, radial, ceramic radial? that kind of stuff)

If you need to ask questions like that then you need to do som reading.

(will the pvc interfere any with the electromagnetic waves?)

When was the last time you saw plastic interfere with radio waves.

also is there any way i can tell which side the elec. flows out of the socket? like which side it comes from and which side it goes to when looking at the socket?

Wall sockets provide AC current, something transformers only work with.

Stun guns have VERY little current. Current is whats doing all the work here. For a multi stage coil gun that is true. But not all coil guns use multiple stages. There are such things as single stage coil guns.
The problem with multi stage coil guns is you either need to time everything perfectly and put into account such things as the mass of the projectile etc... Sensors could be used to detect the projectile just before it enters the next coil and then they would trigger the discharge of that coil stage. Spheres make VERY poor projectiles for electromagnetic weapons. They only cross the electromagnetic fields for a very short time as apposed to a rod or slug would. Advantages of the spheres is that it is very easy to make loading systems.
