Coilgun(s)

[paradox1a]

Alright so I'm looking to start a coilgun or rather coilguns project. I have a lot of it worked out already... But inevitably I want to make sure that said coilgun will fall just short of ripping apart the space-time continuum! Yes it seems a little shall we say overly ambitious but it sounds like it could be fun! . So here is my question, for the number of stages i should use from my understanding a multistage will produce much more power out of the gun. Is this correct or not? Any opinions are more then welcome on what supplies are going to be used. I know I'm being a little vague on this but I do need to get off to bed.
