Homebrew PCBs

Steve,
      I use precut surplus PCB stock. I think I saw on Think and 
Tinker that the Mechanical Etching bits can be used to scribe and
snap board. I have a feeling this only works with some types. I
scribe and snap Perfboard on the holes.

                                            John
