I have no idea where this should go. It isn't gun smithing or anything.... so I will put it into the *generalized* forum. I am going to make a gauss gun, and I hope it will be successful. I was browsing the internet the other day and found this: [ame]http://www.youtube.com/watch?v=RKyGDWeblQw[/ame] In that video it shows a man using magnets to shoot a ball. I was intrigued and searched further. I found this: [ame]http://www.youtube.com/watch?v=Z7CyPtF0ChA[/ame] The idea is very original. It uses a magnet to pull a ball until it touches the magnet and then transfers its energy into a ball that is farther away from the original magnet so that it is unaffected/less affected by the original magnets pull. After the second ball leaves with the original balls velocity it is grabbed by the next magnet and that magnet in turn creates even MORE velocity. The result is unlimited speed. The Navy is developing cannon that will shot projectiles using this concept. The projectile will be moving at mach 8! Now I have been searching and I have found that no one has taken this idea seriously and developed a rifle out of it. One guy made a semi rifle but it wasn't constructed very well. In this video it shows exactly how fast these little one can go: [ame]http://www.youtube.com/watch?v=e0pAHF1yamg[/ame] I plan on making a set up with balls that small or smaller. The more sets of magnets you have the faster it will move. I did a little math and figured that I could fit 30 of what he has inside of a long rifle + have the separation be 3 balls instead of 2 (farther away from the magnet so it will not be as affected). If it is farther away you wont have as much negative. It will all eventually shoot a small BB out of a rifled barrel. Well, what do you think? Will it achieve BB gun power or just roll out?
