Subject: Homemade EDM

I belive HSM ran a series of articles on a home made EDM machine. It was
based on a Popular Science article. One of the two articles had a bunch of
errors in it.

I would like to build a machine and wonder if anyone has "bulletproof"
instructions on how to proceed. Does anyone have the articles or other
data on their homepage?? 

Thanks to all.

Regards

Bob Beck

I am not sure it was based on anything other than the original designer's
knowledge and experience, one Robert P Langlois. The project ran for 6
issues (12 months) beginning in May/June 1995.

A call to HSM 1-800-447-367 will get you back issues at $5.00 per copy if
they are available. If issues are not available they will give you the
number of a Microfilm company that has all issues available on film.

I have not yet built it but I followed it closely. I am not sure there
were so many 'errors' as improvements as the project developed over the 12
month period. It would be important to read all 6 issues *before* starting
as things changed for the better along the way.

You might also try to reach Robert Langlois on the NewsGroup 
Sci.Electronics.?  I corresponded with him a year or so ago about this
project, when he wanted to know about homemade circuit boards.
There are several sci.electronics.*** groups, I don't know for sure which
ones he reads more often.  You could also use the dejanews search engine
to look for an old posting of his just to get his net address.

The web pages at http://plains.uwyo.edu/~metal
have a brief section on EDM.  The Pop Sci article is sort of the
grand-daddy of them all, but in no way resembles the HSM series.
