Self made EDM spark eroding machine with the DIY book of Ben Fleming for the home workshop

Self made EDM spark eroding machine with the DIY book of Ben Fleming for the home workshop Here I show my DIY homemade EDM machine with much examples of operating and setups. I am always happy for comments and suggestions especially regarding my problems with unstable burn of small electrodes, excessive wear and the performance of home made pulse EDM solutions. If I can't fix the problems maybe I will try to make a pulse EDM to machine the small slots for the heat exchangeers of my stirling engines. It is really painful to make them conventionally :-( .
