John Robb's latest post on DIY rockets reminds me of the book 'Adventures from the Technology Underground: Catapults, Pulsejets, Rail Guns, Flamethrowers, Tesla Coils, Air Cannons, and the Garage Warriors Who Love Them' by William Gurstelle. Gurstelle has a blog here on these DIY weapon subcultures if anyone is interested.
