I am thinking about building and experimenting with EDM. I am conserned about power shocks damaging wires in walls, appliances and electricity meter, so i thought i could totaly isolate power for edm:
using two drilling machines connected by shaft: one runing from power-grid and other being off grid and "PRODUCING" electricity for EDM?
Is this feasible?
Will power shocks destroy such dynamo, will brushes burn off?
thanks for any advices
