Ive seen bullets with rifiling on the bullet, so the air makes it spin, but the projectile would have to move pretty fast.

i wonder if there was a way to magnetically spin the projectile while still in the barrel. Mabye with a setup similar to an ac induction motor... the projectile would have to be non conductive with conductive pathways in it for the induced current to flow. Do you think that this idea could spin the projectile to an adequate rpm?

You would need an AC motor drive running at the frequency you need depending on how many poles you have. You probably also need to have it sitting on a bearing so it doesn't grind on the barrel. I think you could get it to work, and it would look reall really cool. It won't be that easy to do though.

I think i'm going to play around with the idea a little bit... i want to make this coilgun really fun. I also like designing new improvements instead of just following directions, makes it all more enjoyable.
