We have assembled an index of sources for materials, tools and information that may be of use to FIRST teams. Check out http://ranier.hq.nasa.gov/Metal/MetalSites.html
While this is not the be-all and end-all metalworking index, it is intended to hit most of the major information sources and suppliers that may be of use to anyone doing metalworkins/prototyping on the scale of FIRST robots. Hopefully, it will be of use to your teams.
If you don’t see your favorite link listed, just let us know - we will be happy to add it!
Also, for more robot-specific information, check out http://ranier.hq.nasa.gov/telerobotics_page/internetrobots.html
