Alternatively, wind the wire onto a mandrill.

Or would that be a mandrel?


I've seen both spellings recommended in print, but winding wire onto a
mandrill will be far more entertaining.


what i have seen is a 'coil form' is something that remains inside the coil
once it is complete. a 'coil former' is a removable frame or device that
you wind the coil on and then remove. These can be for large coils that are
then supported by something else, like tank coils in amps. Or for coils
that are then put on a core that is built separately, as in a high voltage
power transformer.
