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.
