Re: build an edm

Hi Babar,

There are 3 sources I have found so far.

I have not read any of these books.

#1, Dan has plans on his site, and photos. and would offer some
support if you had questions.
www.seanet.com/~dmauch

#2 Village press offers the book that I assume is an edited
compilation of the articles from Home shop machinest
many places to buy, $18.00 at village press if you can find the link.
(poor site design)
http://www.build-stuff.com/015book.htm
copywrite 1997- 54 pages

#3 e-bay "BUILD A METAL DISINTEGRATER EDM TAP REMOVER " 34 pages
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1924903934
