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...........

thats cool!

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

author

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)

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

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.

great only one thing where are the instructions and how far does it shoot

author
onlyonething (author)catdog2009-04-17

this one shot about about 45-50 feet,i could hit a pop can from about 20 feet so the accuracy is pretty good too

author
catdog (author)catdog2009-04-09

i would agree with you if the name of this site wasn't INSTRUCTables

ditto for me ,If you are going to the trouble to do something, how you did it would be a very good idea.......Video's are neat to watch but while putting together printed instructions are best.......
