Re: build an edm (links)

here is the link to the 125 page book "Build and EDM" by Robert
Langolis.

http://www.okdpm.com/tek9.asp?pg=products&specific=jnoploc8
of course it is on backorder.

so, besides the links below and the NAMES pictures,
http://www.pacificsun.ca/~robert/2001/part05.htm

this appears to be the 'state of the industry"

Now, I am really interested in the NAMES Show.
I wish I could go.

if any of you do make it, take as many picturess of EDM stuff as you
can. the rest of us would be greatlful for your efforts.
