We’ve hit on a few EM projectile systems recently, so [Jason Rollette] thought it would be a good time to cover his railgun. I couldn’t agree more. Jason has been keeping his Railgun Blog up-to-date from nearly day one. Right now he is assembling a larger capacitor bank to power the gun. The PVC piping you see in the picture is part of the injection rig; If the projectile is stationary when the gun is fired it would get welded to the rails (if not worse). Check out Jason’s Railgun Blog for details on his project plus a lot of informative links.
The videos are great!
Also, if you want more basic info on railguns check out the wiki:

Another great site for reailgun info is http://wiki.4hv.org/index.php/Rail_gun
They also have a large population of people extremly knowledgable about high voltage projects (I.E. Tesla Coils, Van De Graff, Voltage Multipliers, etc)
Very nice railgun. Until now I thought railguns were a fictitious weapon from Quake. That gun would looks so awesome on my driveway.
