Second Coil

View of finished coil. To alleviate potential for the bobbin chafing
the magnet wire, identical rubber bands were placed at each edge.
As the coil was wound slowly around a "zillion" times to achieve
a measured resistance of 600 ohms, it was coated with 2-part epoxy.

other sizes: small medium large original auto
