Hi I found this on youtube:
EDM
Handy things to have!
Portable ones are available, but of course they are not cheap.
I made a pretty “cheezy “ one a while back, using a simple circuit that was published back in the sixties, very poor results.
Two books are available telling how to make your own, one includes a printed circuit board, but finding all the needed components was not so easy. Especially the proper capacitors.
I gave up.
Small EDMs are sometimes available but again, a very used machine, with older electronics, and still a few thousand dollars.
Lots of potential, but I finally decided that I there are some tools that I just will have to live without!
