# coilgun coil with 2 wires to decrease resistance?

after i finished my coilgun. i found that my coil which has a resistance of 3 ohms is not efficient enough for my 1920uf cap bank at 310v.

i've read that high resistance coils need high voltages and low capacitance from the capacitor banks. and that low resistance can use both high voltages and high bigger capacitor banks to increase the current and drain the capacitor more quickly so that the projectile will not be sucked back.

so i am wondering if i can wound a coil that has 2 wires to decrease resistance,

the current one is about 30mm in length and have 12 layers of 1.024mm of enamel coated wire.

it is just that i don't have bigger wire which has a lower resistance.

and i also did not solved my switching problem. i already damaged 3 heavy duty water heater switches

here is the picture

What's the barrel made of ? If its a plastic, and we can say its aircored, you can work out the inductance, and calculate the stored energy.

Steve

Did you add the limiting resistor for charging ?

Steve

As for doubling up the wire, that should lower the resistance, but as steve says, will change other variables in the circuit...

yeah the impediance. i should have added a couple of fast diode

what about winding the coil with two wires
