    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

    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

    can you post instructions for this pleasee? all the other coilgun instructions arent really step-by-step so i have had a hard time building one.

    i have already taken this one apart but i can post a new one one with step by step instructions as soon as i get my camera...give me about a week

    I really would like to see instructions on this one too, it looks like a nice simple design that would be a fun little project.
