    Hi,
    I’m building a railgun and I have 2 questions for you:
    fiest I’m using compressed air and I want to buy a cheap compressor
    like yours,but how much pressure can they give?Most of them are rated
    300 or 250 psi but is that true?how much yours really give?

    And second to charge the caps do you use a variac?If so wont do you
    limit the current,big resistor?
    thanks
    Sebastien
    ps:Where are you from?
