how do i wind the coil e.g.
===== (barrel)
           <- one layer this way
one layer that way ->
etc.

thats why i wont work olny one way or your cross the magnetic feild

i made a coilgun with a bigger barrel and overall structure. i notice that when i charge for a minute nd a half, it does fine but very weak.when i go longer, it just sort of jiggles in the barrel. help? o i used two different gauges of wire connected in the middle of the coil (youll see) ill put up some pics...........

The neeter u wind the coil the better, wind it in only one direction too. when u get to the end run it streight back and start on the next layer, that will give u the best magnetic feild

so closeup you can see the different gauges of wire and sorta see my circut setup.... the metal rod is ammo

Hello guys
I am making a coilgun made of a disposable camera and some capacitors.
I have made a drawing with google sketch-up. Could you please check if I have made all the connections right? ( I am not an expert ……… yet)

please reply!

but when making the coil. does the wire need to be insulated so that they don't touch each other. otherwise it will be just like a metal tube

why didnt you just put a battery in the area where it is empty and if you have enough room put another extra batterey for if the other one runs out
