Homebrew PCBs

Now that I am retired and no longer have access fine facilities, I use a 
carbide-tipped hand
tool (scribe) that I believe I purchased from Edmund Scientific or some 
place like that. I score the
PC material and snap it clean over the straight edge of my work bench. I 
think carbide tipped
scribes or scoring tools are readily available, and they last a long 
time, even when scoring
epoxy glass.
