I have to admit, the EDM process sounds very interesting. I am 99%
certain it could be easily adapted to any existing CNC router (or
mill). My fear is the power supply - I don't know enough yet about
the electronics to make the power supply. By chance, do you have
that link to the information you and the other fellow were talking
about a couple of days ago? I guess I should look that over to see
if it is basic enough for me to understand it.
