wire edm

hi
i am new to your group.I made a dan maulch cnc milling
machine using draw guides, it worked well,Dan was very
helpful.
Now I want to make a wire EDM machine.
I surfed and found the club. The Home Shop Machinist had
an article, but I dont have it.
Any body know of some places to look for information.

My wood router is 24in x 24 in , I run the maxnc
controller software, generate g-code with BOBCAD , and
drawings in genericcad cadd6 (bought out by Autocad).
I hope to do the same with wire edm.
Thanks
