The best into is a review of Jon Elson's page. very simple
explanation.

Jon Elson's Mini-EDM
http://pico-systems.com/edm.html

and for more into data, get a copy of the langolis book and/or the
other build an edm book, both are on e-bay for a good price.

Dan has plans, although I have not reviewed them, as I understand,
his plans get good reviews and his plans were the only ones with wire
as a design.

videos on his site.

plans for sinker and wire

Many people read the langolis book build a complete unit from that.

I think the other e-bay book is similar, just don't get the one with
patents. all that book has is pages of patents, no engineering
notes. interesting for the more advanced, but not a intro level.

and if you build, realize that EDM is a very very slow process. a
one inch drill can remove a cubic inch of metal in under a minute.
it could take 4 hours to bore a 1/8 inch hole, 1" deep with EDM.

The nice thing is that while it is working, you can clean up the
shop, hang those shelves and paint the place.
