Ferric chloride gone into liquid

[BusyBee]

I've never tried it, but you can mechanically mill the copper rather than etch it.  A CNC mill can automate the process. BusyBee's little board in the last post looks like a crude version of of milling.  BusyBee also reminded me that I too used paint (car touch-up) as a resist.

I can remember finishing boards by hand but do remember totally cutting by hand was possible but error prone and tedious, so I think that that board was probably a combination. I have never really had access to machine tools except at college.

I still prefer veroboard, or similar or my modern take on etched board which is to use manhattan layout with copper faced board and glued on islands.
