Guide links needed, router techniques

Does anyone know where I can find a guide to different router techniques realating to car customization?  I'm asking because I read a post somewhere where the guy had a square cutting jig of some sort to make perfect sqaures/recatangles and such.  Also, does anyone know where to find a guide on putting in a custom car pc?  I've got ideas on how to put the car pc in but I've seen some peripherals that I don't know wheter or not they are neccesary when using the PC.  Anyone have any good links on building a good fiberglassed frame for a center console or even links to pictures or other installs?  I've seen a few on this site and have helped out a lot.  Or if you all have any good web addresses for other forums that have good content it would be appreciated.

this is where i got the square tool from check out all the stuf here lots on cool items for custom fab. as far as books on router stuff i go to BARNS AND NOBLE sit in the magazine section and read wood working mags for about an hour one or twice a week and if i read any thing realy good i might just buy one
