I'm not too sure what Frank from Holland sent - don't remember that.

But, take a look at my web page on my 'mini-EDM'. I used it for burning
out taps. It worked very well. If a fluid flow was added, it would do even
better. I hope that Fred Proctor has kept in mind the suggestion that there
be a way to control the feed of an axis by feeding a sensed EDM current
into one of the STG card's ADC channels.
