The following description was provided: ================================================================= Here is my edm project. The power supply was made from instructions in a book, "Build An EDM", written by Robert Langlois. The machine itself is my own design. Table and saddle ride on PACIFIC BEARINGS and 1/2" Thompson shafting. I used a 90v dc gearmotor controlled by an Allen Bradley, PLC, to raise and lower the electrode automatically. When the depth is reached, the electrode raises and shuts down the machine. Submitted by Jim Glass Genoa, IL
