EDM and HSM Magazine

Back in 94 or 95 (I can't remember when exactly), I purchased the
series of HSM Magazine with Robert Langlois' great build plans for a
sinker EDM. I was left a little disappointed when the very last
article alluded to some specific circuits but didn't go into enough
detail to finish them.

Lately I heard that the same author published a new series in last
year's HSM Mag. for a wire EDM system. I am curious to know if
anyone has done anything with the articles (or if they are even
plans for building a wire EDM)?

Please let me know if this subject has been addressed and where I
can find the thread. I searched for "Langlois" and didn't come up
with much.

Thanks,

Oliver
