  1. Choose any thickness of wire— from .005 to 0.25. Thin wires are safer and cut cleaner, but they sag and break if stressed. Large wires are more durable.
  2. Use the transformer and control unit shown.
  3. Design a fixture to hold the wire— use a spring to hold a constant tension in the wire.
  4. We offer components only— not instructions for building. This schematic is shown only to indicate how a system could be configured. Consult an electrcian or electrical engineer for proper wiring and setup.
