questions for rail gun?
1.) Where are some good places that i can buy parts for a decent railgun (i already know of some places like home depot (for the rails and casing) and radio shack (for some of the minor components)?
2.) Is there a better material (cost and in efficiency) than copper for the rail? (i heard aluminum is good, and i also heard silver is good but silver is expensive)
3.) what are good power supplies (something fairly mobile would do nicely, and i am not asking for specific requirements i am asking what other people have used as power supplies)
if you commented on my last question, don't on this one please, i got your opinion. I would like an answer that is to the point please and not something that has to do with whether or not i should build a rail gun (i have gotten answers like that before which bugs me when i ask a question).
