Brian,

Jon is a member of this group, and a few of us have made that unit.

There is a better machine, one that is described in Ben Flemmings
book, or the book by Langolis, I think both are in the links section
of this site, and the EDM_CNC site.

There are also a few EDM groups.

http://finance.groups.yahoo.com/group/EDM_CNC/

and

http://tech.groups.yahoo.com/group/EDMHomeBuilders/

The second one is by Flemming and you can buy his book directly.

the improvement over Jon's pages is that Flemming uses a motor and
circuit to feed the electrode and is not a hand feed operation.
