Will has a good starter on making your own CNC machine – “Ready for some hard core gadget creation? If you thought your dremel tool was handy before, in today’s How-To we’ll start building our own CNC machine. Aside from the geek factor, it can be handy for making things like PC boards without chemicals or maybe some little styrofoam voodoo heads of all your enemies, uh friends. Gentlemen, start your soldering irons.”Link.
