Wiseguy, the former is just something to wind the coil on, so that it is the right size to slip over the transformer core. You wind the coil, have some tape under it and up the ends and tie the coil with the tape, then remove the former. Generally then you tape the coil and fit it to the core with some insulation between it and the core.
