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 :-( .
Greetings
Ralf
