A print head, particularly suitable for use in an electrolytic printer, is fabricated by winding a coil onto a square mandrel. Depending upon diameter and center-to-center spacing, this assembly could be used to form a two- or four- channel print head. Each side of the mandrel becomes one channel of the print head. Length is no object in forming a head using this method, since standard 8" or 11" head configurations could be done on a lathe set-up. A print head was made using a lathe and setting automatic feed rate to a pitch of .008" per revolution. This places the winding, which is being fed onto the mandrel, on .008" centers. Insulated and relatively inexpensive copper wire #34 gauge was used on an experimental basis. Platinum would probably be the best choice for commercial print head implementation.
