Homebrew PCBs

Hi John,

I recall the JFax, and AEA's fax.  Milling PCB's is quite a challenge,
and even more interesting!  

I didn't quite get the "scratch and etch".  This is for isolation, like
milling?  Just enough to remove resist?  

What about a burnishing bit, perhaps abrasive, to scrub off resist?  It
would have to be quite small dia.  Just mill through the resist.
