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!

He dosen’t mention the price? It does look to be an improvement over the designs in the books I mentioned.

I’ll have to look for future video!

Thanks for posting!
