Forming Coils to Make Flexible Wire Connections
Forming Wire Coils
When connections are made to bells and batteries with small copper wires covered with cotton or silk, it is necessary to have a coil in a short piece of the line to make it flexible. A good way to do this is to provide a short rod about 3/16 in. in diameter cut with a slit in one end to hold the wire and a loop made on the other end to turn with the fingers. The end of the wire is placed in the slit and the coil made around the rod by turning with the loop end.
