3. COIL DIAMETERS-Depending upon wire size, coils as
small as a fraction of an inch and up to 12" in outside
diameter can be made on Perkins coilers. The position of
the horizontal slide and vertical adjustment screw with the
large knurled head, located below the coiling point, deter-
mines coil diameter. A guide for determining the smallest
diameter coil which can be'made with wires or different
diameters is shown in the following table. ,Soft wires"or
6. COlLER OPERATORS-Perkins Wire Coilers are ex-
tremely versatile machines. Most users designate one or .:
two men in each department to operate the coiler. With .
minimum practice they rapidly become expert in turning
out springs or coils quickly. accurately and at low cost.
